Implements Ogre::Resource.

SubMesh* Ogre::Mesh::createSubMesh | ( | void |  | ) |

Creates a new SubMesh.

Remarks:
  Method for manually creating geometry for the mesh. Note - use with extreme caution - you must be sure that you have set up the geometry properly.

SubMesh* Ogre::Mesh::createSubMesh | ( | const String & | name | ) |

Creates a new SubMesh and gives it a name.

void Ogre::Mesh::nameSubMesh | ( | const String & | name,
|  | ushort | index |

|  | const String & | newGroup = `StringUtil::BLANK` |
| ) |  |  |

Makes a copy of this mesh object and gives it a new name.

Remarks:
  This is useful if you want to tweak an existing mesh without affecting the original one. The newly cloned mesh is registered with the MeshManager under the new name.

Parameters:

  | newName | The name to give the clone
  | newGroup | Optional name of the new group to assign the clone to; if you leave this blank, the clone will be assigned to the same group as this Mesh.

const AxisAlignedBox& Ogre::Mesh::getBounds | ( | void |  | ) | const

Get the axis-aligned bounding box for this mesh.

Real Ogre::Mesh::getBoundingSphereRadius | ( | void |  | ) | const

Gets the radius of the bounding sphere surrounding this mesh.

void Ogre::Mesh::_setBounds | ( | const AxisAlignedBox & | bounds,
|  | bool | pad = `true` |
| ) |  |  |

Manually set the bounding box for this Mesh.

Remarks:
  Calling this method is required when building manual meshes now, because OGRE can no longer update the bounds for you, because it cannot necessarily read vertex data back from the vertex buffers which this mesh uses (they very well might be write-only, and even if they are not, reading data from a hardware buffer is a bottleneck).

Parameters:

  | pad | If true, a certain padding will be added to the bounding box to separate it from the mesh

void Ogre::Mesh::_setBoundingSphereRadius | ( | Real | radius | ) |

Manually set the bounding radius.

Remarks:
  Calling this method is required when building manual meshes now, because OGRE can no longer update the bounds for you, because it cannot necessarily read vertex data back from the vertex buffers which this mesh uses (they very well might be write-only, and even if they are not, reading data from a hardware buffer is a bottleneck).

void Ogre::Mesh::setSkeletonName | ( | const String & | skelName | ) |

Sets the name of the skeleton this Mesh uses for animation.

Remarks:
  Meshes can optionally be assigned a skeleton which can be used to animate the mesh through bone assignments. The default is for the Mesh to use no skeleton. Calling this method with a valid skeleton filename will cause the skeleton to be loaded if it is not already (a single skeleton can be shared by many Mesh objects).

Parameters:

  | skelName | The name of the .skeleton file to use, or an empty string to use no skeleton

bool Ogre::Mesh::hasSkeleton | ( | void |  | ) | const

Returns true if this Mesh has a linked Skeleton.

bool Ogre::Mesh::hasVertexAnimation | ( | void |  | ) | const

Returns whether or not this mesh has some kind of vertex animation.

const SkeletonPtr& Ogre::Mesh::getSkeleton | ( | void |  | ) | const

Gets a pointer to any linked Skeleton.

Returns:
  Weak reference to the skeleton - copy this if you want to hold a strong pointer.

const String& Ogre::Mesh::getSkeletonName | ( | void |  | ) | const

Gets the name of any linked Skeleton.

void Ogre::Mesh::_initAnimationState | ( | AnimationStateSet * | animSet | ) |

Initialise an animation set suitable for use with this mesh.

Remarks:
  Only recommended for use inside the engine, not by applications.

void Ogre::Mesh::_refreshAnimationState | ( | AnimationStateSet * | animSet | ) |

Refresh an animation set suitable for use with this mesh.

Remarks:
  Only recommended for use inside the engine, not by applications.

void Ogre::Mesh::addBoneAssignment | ( | const VertexBoneAssignment & | vertBoneAssign | ) |

Assigns a vertex to a bone with a given weight, for skeletal animation.

Remarks:
  This method is only valid after calling setSkeletonName. Since this is a one-off process there exists only 'addBoneAssignment' and 'clearBoneAssignments' methods, no 'editBoneAssignment'. You should not need to modify bone assignments during rendering (only the positions of bones) and OGRE reserves the right to do some internal data reformatting of this information, depending on render system requirements.

  This method is for assigning weights to the shared geometry of the Mesh. To assign weights to the per-SubMesh geometry, see the equivalent methods on SubMesh.

void Ogre::Mesh::clearBoneAssignments | ( | void |  | ) |

Removes all bone assignments for this mesh.

Remarks:
  This method is for modifying weights to the shared geometry of the Mesh. To assign weights to the per-SubMesh geometry, see the equivalent methods on SubMesh.

void Ogre::Mesh::_notifySkeleton | ( | SkeletonPtr & | pSkel | ) |

Internal notification, used to tell the Mesh which Skeleton to use without loading it.

Remarks:
  This is only here for unusual situation where you want to manually set up a Skeleton. Best to let OGRE deal with this, don't call it yourself unless you really know what you're doing.

BoneAssignmentIterator Ogre::Mesh::getBoneAssignmentIterator | ( | void |  | ) |

Gets an iterator for access all bone assignments.

void Ogre::Mesh::generateLodLevels | ( | const LodDistanceList & | lodDistances,
|  | ProgressiveMesh::VertexReductionQuota | reductionMethod,
|  | Real | reductionValue |
| ) |  |  |

Automatically generates lower level of detail versions of this mesh for use when a simpler version of the model is acceptable for rendering.

Remarks:
  There are 2 ways that you can create level-of-detail (LOD) versions of a mesh; the first is to call this method, which does fairly extensive calculations to work out how to simplify the mesh whilst having the minimum affect on the model. The alternative is to actually create simpler versions of the mesh yourself in a modelling tool, and having exported them, tell the 'master' mesh to use these alternative meshes for lower detail versions; this is done by calling the createManualLodLevel method.

  As well as creating the lower detail versions of the mesh, this method will also associate them with depth values. As soon as an object is at least as far away from the camera as the depth value associated with it's LOD, it will drop to that level of detail.

  I recommend calling this method before mesh export, not at runtime.

Parameters:

  | lodDistances | A list of depth values indicating the distances at which new lods should be generated.
  | reductionMethod | The way to determine the number of vertices collapsed per LOD
  | reductionValue | Meaning depends on reductionMethod, typically either the proportion of remaining vertices to collapse or a fixed number of vertices.

ushort Ogre::Mesh::getNumLodLevels | ( | void |  | ) | const

Returns the number of levels of detail that this mesh supports.

Remarks:
  This number includes the original model.

const MeshLodUsage& Ogre::Mesh::getLodLevel | ( | ushort | index | ) | const

Gets details of the numbered level of detail entry.

void Ogre::Mesh::createManualLodLevel | ( | Real | fromDepth,
|  | const String & | meshName |
| ) |  |  |

Adds a new manual level-of-detail entry to this Mesh.

Remarks:
  As an alternative to generating lower level of detail versions of a mesh, you can use your own manually modelled meshes as lower level versions. This lets you have complete control over the LOD, and in addition lets you scale down other aspects of the model which cannot be done using the generated method; for example, you could use less detailed materials and / or use less bones in the skeleton if this is an animated mesh. Therefore for complex models you are likely to be better off modelling your LODs yourself and using this method, whilst for models with fairly simple materials and no animation you can just use the generateLodLevels method.

Parameters:

  | fromDepth | The z value from which this Lod will apply.
  | meshName | The name of the mesh which will be the lower level detail version.

void Ogre::Mesh::updateManualLodLevel | ( | ushort | index,
|  | const String & | meshName |
| ) |  |  |

Changes the alternate mesh to use as a manual LOD at the given index.

Remarks:
  Note that the index of a LOD may change if you insert other LODs. If in doubt, use getLodIndex().

Parameters:

  | index | The index of the level to be changed
  | meshName | The name of the mesh which will be the lower level detail version.

ushort Ogre::Mesh::getLodIndex | ( | Real | depth | ) | const

Retrieves the level of detail index for the given depth value.

ushort Ogre::Mesh::getLodIndexSquaredDepth | ( | Real | squaredDepth | ) | const

Retrieves the level of detail index for the given squared depth value.

Remarks:
  Internally the lods are stored at squared depths to avoid having to perform square roots when determining the lod. This method allows you to provide a squared length depth value to avoid having to do your own square roots.

bool Ogre::Mesh::isLodManual | ( | void |  | ) | const

Returns true if this mesh is using manual LOD.

Remarks:
  A mesh can either use automatically generated LOD, or it can use alternative meshes as provided by an artist. A mesh can only use either all manual LODs or all generated LODs, not a mixture of both.

Definition at line 454 of file OgreMesh.h.

void Ogre::Mesh::_setLodInfo | ( | unsigned short | numLevels,
|  | bool | isManual |
| ) |  |  |

Internal methods for loading LOD, do not use.

void Ogre::Mesh::_setLodUsage | ( | unsigned short | level,
|  | MeshLodUsage & | usage |
| ) |  |  |

Internal methods for loading LOD, do not use.

void Ogre::Mesh::removeLodLevels | ( | void |  | ) |

Removes all LOD data from this Mesh.

void Ogre::Mesh::setVertexBufferPolicy | ( | HardwareBuffer::Usage | usage,
|  | bool | shadowBuffer = `false` |
| ) |  |  |

Sets the policy for the vertex buffers to be used when loading this Mesh.

Remarks:
  By default, when loading the Mesh, static, write-only vertex and index buffers will be used where possible in order to improve rendering performance. However, such buffers cannot be manipulated on the fly by CPU code (although shader code can). If you wish to use the CPU to modify these buffers, you should call this method. Note, however, that it only takes effect after the Mesh has been reloaded. Note that you still have the option of manually repacing the buffers in this mesh with your own if you see fit too, in which case you don't need to call this method since it only affects buffers created by the mesh itself.

  You can define the approach to a Mesh by changing the default parameters to MeshManager::load if you wish; this means the Mesh is loaded with those options the first time instead of you having to reload the mesh after changing these options.

Parameters:

  | usage | The usage flags, which by default are HardwareBuffer::HBU_STATIC_WRITE_ONLY
  | shadowBuffer | If set to true, the vertex buffers will be created with a system memory shadow buffer. You should set this if you want to be able to read from the buffer, because reading from a hardware buffer is a no-no.

void Ogre::Mesh::setIndexBufferPolicy | ( | HardwareBuffer::Usage | usage,
|  | bool | shadowBuffer = `false` |
| ) |  |  |

Sets the policy for the index buffers to be used when loading this Mesh.

Remarks:
  By default, when loading the Mesh, static, write-only vertex and index buffers will be used where possible in order to improve rendering performance. However, such buffers cannot be manipulated on the fly by CPU code (although shader code can). If you wish to use the CPU to modify these buffers, you should call this method. Note, however, that it only takes effect after the Mesh has been reloaded.

Parameters:

  | usage | The usage flags, which by default are HardwareBuffer::HBU_STATIC_WRITE_ONLY
  | shadowBuffer | If set to true, the index buffers will be created with a system memory shadow buffer. You should set this if you want to be able to read from the buffer, because reading from a hardware buffer is a no-no.

HardwareBuffer::Usage Ogre::Mesh::getVertexBufferUsage | ( | void |  | ) | const

Gets the usage setting for this meshes vertex buffers.

Definition at line 513 of file OgreMesh.h.

HardwareBuffer::Usage Ogre::Mesh::getIndexBufferUsage | ( | void |  | ) | const

unsigned short Ogre::Mesh::_rationaliseBoneAssignments | ( | size_t | vertexCount,
|  | VertexBoneAssignmentList & | assignments |
| ) |  |  |

Rationalises the passed in bone assignment list.

Remarks:
  OGRE supports up to 4 bone assignments per vertex. The reason for this limit is that this is the maximum number of assignments that can be passed into a hardware-assisted blending algorithm. This method identifies where there are more than 4 bone assignments for a given vertex, and eliminates the bone assignments with the lowest weights to reduce to this limit. The remaining weights are then re-balanced to ensure that they sum to 1.0.

Parameters:

  | vertexCount | The number of vertices.
  | assignments | The bone assignment list to rationalise. This list will be modified and entries will be removed where the limits are exceeded.

Returns:
  The maximum number of bone assignments per vertex found, clamped to [1-4]

void Ogre::Mesh::_compileBoneAssignments | ( | void |  | ) |

Internal method, be called once to compile bone assignments into geometry buffer.

Remarks:
  The OGRE engine calls this method automatically. It compiles the information submitted as bone assignments into a format usable in realtime. It also eliminates excessive bone assignments (max is OGRE_MAX_BLEND_WEIGHTS) and re-normalises the remaining assignments.

void Ogre::Mesh::_updateCompiledBoneAssignments | ( | void |  | ) |

Internal method, be called once to update the compiled bone assignments.

Remarks:
  The OGRE engine calls this method automatically. It updates the compiled bone assignments if requested.

void Ogre::Mesh::buildTangentVectors | ( | VertexElementSemantic | targetSemantic = `VES_TANGENT`,
|  | unsigned short | sourceTexCoordSet = `0`,
|  | unsigned short | index = `0` |
| ) |  |  |

This method builds a set of tangent vectors for a given mesh into a 3D texture coordinate buffer.

Remarks:
  Tangent vectors are vectors representing the local 'X' axis for a given vertex based on the orientation of the 2D texture on the geometry. They are built from a combination of existing normals, and from the 2D texture coordinates already baked into the model. They can be used for a number of things, but most of all they are useful for vertex and fragment programs, when you wish to arrive at a common space for doing per-pixel calculations.

  The prerequisites for calling this method include that the vertex data used by every SubMesh has both vertex normals and 2D texture coordinates.

Parameters:

  | targetSemantic | The semantic to store the tangents in. Defaults to the explicit tangent binding, but note that this is only usable on more modern hardware (Shader Model 2), so if you need portability with older cards you should change this to a texture coordinate binding instead.
  | sourceTexCoordSet | The texture coordinate index which should be used as the source of 2D texture coordinates, with which to calculate the tangents.
  | index | The element index, ie the texture coordinate set which should be used to store the 3D coordinates representing a tangent vector per vertex, if targetSemantic is VES_TEXTURE_COORDINATES. If this already exists, it will be overwritten.

bool Ogre::Mesh::suggestTangentVectorBuildParams | ( | VertexElementSemantic | targetSemantic,
|  | unsigned short & | outSourceCoordSet,
|  | unsigned short & | outIndex |
| ) |  |  |

Ask the mesh to suggest parameters to a future buildTangentVectors call, should you wish to use texture coordinates to store the tangents.

Remarks:
  This helper method will suggest source and destination texture coordinate sets for a call to buildTangentVectors. It will detect when there are inappropriate conditions (such as multiple geometry sets which don't agree). Moreover, it will return 'true' if it detects that there are aleady 3D coordinates in the mesh, and therefore tangents may have been prepared already.

Parameters:

  | targetSemantic | The semantic you intend to use to store the tangents if they are not already present; most likely options are VES_TEXTURE_COORDINATES or VES_TANGENT; you should use texture coordinates if you want compatibility with older, pre-SM2 graphics cards, and the tangent binding otherwise.
  | outSourceCoordSet | Reference to a source texture coordinate set which will be populated
  | outIndex | Reference to a destination element index (e.g. texture coord set) which will be populated

void Ogre::Mesh::buildEdgeList | ( | void |  | ) |

Builds an edge list for this mesh, which can be used for generating a shadow volume among other things.

void Ogre::Mesh::freeEdgeList | ( | void |  | ) |

Destroys and frees the edge lists this mesh has built.

void Ogre::Mesh::prepareForShadowVolume | ( | void |  | ) |

This method prepares the mesh for generating a renderable shadow volume.

Remarks:
  Preparing a mesh to generate a shadow volume involves firstly ensuring that the vertex buffer containing the positions for the mesh is a standalone vertex buffer, with no other components in it. This method will therefore break apart any existing vertex buffers this mesh holds if position is sharing a vertex buffer. Secondly, it will double the size of this vertex buffer so that there are 2 copies of the position data for the mesh. The first half is used for the original, and the second half is used for the 'extruded' version of the mesh. The vertex count of the main VertexData used to render the mesh will remain the same though, so as not to add any overhead to regular rendering of the object. Both copies of the position are required in one buffer because shadow volumes stretch from the original mesh to the extruded version.

  Because shadow volumes are rendered in turn, no additional index buffer space is allocated by this method, a shared index buffer allocated by the shadow rendering algorithm is used for addressing this extended vertex buffer.

EdgeData* Ogre::Mesh::getEdgeList | ( | unsigned int | lodIndex = `0` | ) |

Return the edge list for this mesh, building it if required.

Remarks:
  You must ensure that the Mesh as been prepared for shadow volume rendering if you intend to use this information for that purpose. The LOD at which to get the edge list, 0 being the highest.

const EdgeData* Ogre::Mesh::getEdgeList | ( | unsigned int | lodIndex = `0` | ) | const

Return the edge list for this mesh, building it if required.

Remarks:
  You must ensure that the Mesh as been prepared for shadow volume rendering if you intend to use this information for that purpose. The LOD at which to get the edge list, 0 being the highest.

bool Ogre::Mesh::isPreparedForShadowVolumes | ( | void |  | ) | const

Returns whether this mesh has already had it's geometry prepared for use in rendering shadow volumes.

Definition at line 643 of file OgreMesh.h.

bool Ogre::Mesh::isEdgeListBuilt | ( | void |  | ) | const

|  | const Matrix4 * | boneMatrices,
|  | const IndexMap & | indexMap |
| ) |  |  | `[static]`

Prepare matrices for software indexed vertex blend.

Remarks:
  This function organise bone indexed matrices to blend indexed matrices, so software vertex blending can access to the matrix via blend index directly.

Parameters:

  | blendMatrices | Pointer to an array of matrix pointers to store prepared results, which indexed by blend index
  | boneMatrices | Pointer to an array of matrices to be used to blend, which indexed by bone index
  | indexMap | The index map used to translate blend index to bone index

static void Ogre::Mesh::softwareVertexBlend | ( | const VertexData * | sourceVertexData,
|  | const VertexData * | targetVertexData,
|  | const Matrix4 *const * | blendMatrices,
|  | size_t | numMatrices,
|  | bool | blendNormals |
| ) |  |  | `[static]`

Performs a software indexed vertex blend, of the kind used for skeletal animation although it can be used for other purposes.

Remarks:
  This function is supplied to update vertex data with blends done in software, either because no hardware support is available, or that you need the results of the blend for some other CPU operations.

Parameters:

  | sourceVertexData | VertexData class containing positions, normals, blend indices and blend weights.
  | targetVertexData | VertexData class containing target position and normal buffers which will be updated with the blended versions. Note that the layout of the source and target position / normal buffers must be identical, ie they must use the same buffer indexes
  | blendMatrices | Pointer to an array of matrix pointers to be used to blend, indexed by blend indices in the sourceVertexData
  | numMatrices | Number of matrices in the blendMatrices, it might be used as a hint for optimisation.
  | blendNormals | If true, normals are blended as well as positions

static void Ogre::Mesh::softwareVertexMorph | ( | Real | t,
|  | const HardwareVertexBufferSharedPtr & | b1,
|  | const HardwareVertexBufferSharedPtr & | b2,
|  | VertexData * | targetVertexData |
| ) |  |  | `[static]`

Performs a software vertex morph, of the kind used for morph animation although it can be used for other purposes.

Remarks:
  This function will linearly interpolate positions between two source buffers, into a third buffer.

Parameters:

  | t | Parametric distance between the start and end buffer positions
  | b1 | Vertex buffer containing VET_FLOAT3 entries for the start positions
  | b2 | Vertex buffer containing VET_FLOAT3 entries for the end positions
  | targetVertexData | VertexData destination; assumed to have a separate position buffer already bound, and the number of vertices must agree with the number in start and end

static void Ogre::Mesh::softwareVertexPoseBlend | ( | Real | weight,
|  | const std::map< size_t, Vector3 > & | vertexOffsetMap,
|  | VertexData * | targetVertexData |
| ) |  |  | `[static]`

Performs a software vertex pose blend, of the kind used for morph animation although it can be used for other purposes.

Remarks:
  This function will apply a weighted offset to the positions in the incoming vertex data (therefore this is a read/write operation, and if you expect to call it more than once with the same data, then you would be best to suppress hardware uploads of the position buffer for the duration)

Parameters:

  | weight | Parametric weight to scale the offsets by
  | vertexOffsetMap | Potentially sparse map of vertex index -> offset
  | targetVertexData | VertexData destination; assumed to have a separate position buffer already bound, and the number of vertices must agree with the number in start and end

const SubMeshNameMap& Ogre::Mesh::getSubMeshNameMap | ( | void |  | ) | const

Gets a reference to the optional name assignments of the SubMeshes.

Definition at line 720 of file OgreMesh.h.

void Ogre::Mesh::setAutoBuildEdgeLists | ( | bool | autobuild | ) |

Sets whether or not this Mesh should automatically build edge lists when asked for them, or whether it should never build them if they are not already provided.

Remarks:
  This allows you to create meshes which do not have edge lists calculated, because you never want to use them. This value defaults to 'true' for mesh formats which did not include edge data, and 'false' for newer formats, where edge lists are expected to have been generated in advance.

Definition at line 732 of file OgreMesh.h.

bool Ogre::Mesh::getAutoBuildEdgeLists | ( | void |  | ) | const

Sets whether or not this Mesh should automatically build edge lists when asked for them, or whether it should never build them if they are not already provided.

Removes all morph Animations from this mesh.

VertexData* Ogre::Mesh::getVertexDataByTrackHandle | ( | unsigned short | handle | ) |

Gets a pointer to a vertex data element based on a morph animation track handle.

Remarks:
  0 means the shared vertex data, 1+ means a submesh vertex data (index+1)

void Ogre::Mesh::updateMaterialForAllSubMeshes | ( | void |  | ) |

Iterates through all submeshes and requests them to apply their texture aliases to the material they use.

Remarks:
  The submesh will only apply texture aliases to the material if matching texture alias names are found in the material. If a match is found, the submesh will automatically clone the original material and then apply its texture to the new material.

  This method is normally called by the protected method loadImpl when a mesh if first loaded.

void Ogre::Mesh::_determineAnimationTypes | ( | void |  | ) | const

Internal method which, if animation types have not been determined, scans any vertex animations and determines the type for each set of vertex data (cannot have 2 different types).

bool Ogre::Mesh::_getAnimationTypesDirty | ( | void |  | ) | const

Are the derived animation types out of date?

virtual void Ogre::Resource::preLoadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions before the load process, but after the resource has been marked as 'loading'.

Note:
  Mutex will have already been acquired by the loading thread. Also, this call will occur even when using a ManualResourceLoader (when loadImpl is not actually called)

Definition at line 149 of file OgreResource.h.

virtual void Ogre::Resource::preUnloadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions before the unload process.

Note:
  Mutex will have already been acquired by the unloading thread.

virtual void Ogre::Resource::postUnloadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions after the unload process, but before the resource has been marked as fully unloaded.

Note:
  Mutex will have already been acquired by the unloading thread.

Definition at line 166 of file OgreResource.h.

virtual void Ogre::Resource::queueFireBackgroundLoadingComplete | ( | void |  | ) | `[protected, virtual, inherited]`

Queue the firing of background loading complete event.

virtual void Ogre::Resource::load | ( | bool | backgroundThread = `false` | ) | `[virtual, inherited]`

Loads the resource, if it is not already.

Remarks:
  If the resource is loaded from a file, loading is automatic. If not, if for example this resource gained it's data from procedural calls rather than loading from a file, then this resource will not reload on it's own.

Parameters:

  | backgroundThread | Indicates whether the caller of this method is the background resource loading thread.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

virtual void Ogre::Resource::reload | ( | void |  | ) | `[virtual, inherited]`

Reloads the resource, if it is already loaded.

Remarks:
  Calls unload() and then load() again, if the resource is already loaded. If it is not loaded already, then nothing happens.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

bool Ogre::Resource::isReloadable | ( | void |  | ) | const`[inherited]`

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 228 of file OgreResource.h.

bool Ogre::Resource::isManuallyLoaded | ( | void |  | ) | const`[inherited]`

Is this resource manually loaded?

Definition at line 235 of file OgreResource.h.

virtual void Ogre::Resource::unload | ( | void |  | ) | `[virtual, inherited]`

Unloads the resource; this is not permanent, the resource can be reloaded later if required.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

size_t Ogre::Resource::getSize | ( | void |  | ) | const`[inherited]`

Retrieves info about the size of the resource.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 247 of file OgreResource.h.

virtual void Ogre::Resource::touch | ( | void |  | ) | `[virtual, inherited]`

'Touches' the resource to indicate it has been used.

Reimplemented in Ogre::Material, and Ogre::UnifiedHighLevelGpuProgram.

Referenced by Ogre::Material::touch().

const String& Ogre::Resource::getName | ( | void |  | ) | const`[inherited]`

Gets resource name.

Reimplemented in Ogre::SkeletonInstance.

ResourceHandle Ogre::Resource::getHandle | ( | void |  | ) | const`[inherited]`

Reimplemented in Ogre::SkeletonInstance.

bool Ogre::Resource::isLoaded | ( | void |  | ) | const`[inherited]`

Returns true if the Resource has been loaded, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 270 of file OgreResource.h.

LoadingState Ogre::Resource::isLoading | ( |  | ) | const`[inherited]`

Returns whether the resource is currently in the process of background loading.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 279 of file OgreResource.h.

LoadingState Ogre::Resource::getLoadingState | ( |  | ) | const`[inherited]`

Returns the current loading state.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 286 of file OgreResource.h.

bool Ogre::Resource::isBackgroundLoaded | ( | void |  | ) | const`[inherited]`

Returns whether this Resource has been earmarked for background loading.

Remarks:
  This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 303 of file OgreResource.h.

void Ogre::Resource::setBackgroundLoaded | ( | bool | bl | ) | `[inherited]`

Tells the resource whether it is background loaded or not.

Remarks:

See also:
  Resource::isBackgroundLoaded . Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 313 of file OgreResource.h.

void Ogre::Resource::escalateLoading | ( |  | ) | `[inherited]`

Escalates the loading of a background loaded resource.

Remarks:
  If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

void Ogre::Resource::addListener | ( | Listener * | lis | ) | `[inherited]`

Register a listener on this resource.

See also:
  Resource::Listener

void Ogre::Resource::removeListener | ( | Listener * | lis | ) | `[inherited]`

Reimplemented in Ogre::SkeletonInstance.

Definition at line 337 of file OgreResource.h.

void Ogre::Resource::changeGroupOwnership | ( | const String & | newGroup | ) | `[inherited]`

Remarks:
  This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.

Parameters:

  | newGroup | Name of the new group

ResourceManager* Ogre::Resource::getCreator | ( | void |  | ) | `[inherited]`

Gets the manager which created this resource.

Definition at line 349 of file OgreResource.h.

const String& Ogre::Resource::getOrigin | ( | void |  | ) | const`[inherited]`

Get the origin of this resource, e.g.

a script file name.

Remarks:
  This property will only contain something if the creator of this resource chose to populate it. Script loaders are advised to populate it.

Definition at line 356 of file OgreResource.h.

void Ogre::Resource::_notifyOrigin | ( | const String & | origin | ) | `[inherited]`

Notify this resource of it's origin.

Definition at line 358 of file OgreResource.h.

virtual void Ogre::Resource::_fireBackgroundLoadingComplete | ( | void |  | ) | `[virtual, inherited]`

Firing of background loading complete event.

Remarks:
  You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

bool Ogre::StringInterface::createParamDictionary | ( | const String & | className | ) | `[protected, inherited]`

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks:
  This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).

Parameters:

  | className | the name of the class using the dictionary

Returns:
  true if a new dictionary was created, false if it was already there

Definition at line 176 of file OgreStringInterface.h.

ParamDictionary* Ogre::StringInterface::getParamDictionary | ( | void |  | ) | `[inherited]`

Retrieves the parameter dictionary for this class.

Remarks:
  Only valid to call this after createParamDictionary.

Returns:
  Pointer to ParamDictionary shared by all instances of this class which you can add parameters to, retrieve parameters etc.

const ParameterList& Ogre::StringInterface::getParameters | ( | void |  | ) | const`[inherited]`

Retrieves a list of parameters valid for this object.

Returns:
  A reference to a static list of ParameterDef objects.

virtual bool Ogre::StringInterface::setParameter | ( | const String & | name,
|  | const String & | value |
| ) |  |  | `[virtual, inherited]`

Generic parameter setting method.

Remarks:
  Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

  | name | The name of the parameter to set
  | value | String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns:
  true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

virtual void Ogre::StringInterface::setParameterList | ( | const NameValuePairList & | paramList | ) | `[virtual, inherited]`

Generic multiple parameter setting method.

Remarks:
  Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

  | paramList | Name/value pair list

virtual String Ogre::StringInterface::getParameter | ( | const String & | name | ) | const`[virtual, inherited]`

Generic parameter retrieval method.

Remarks:
  Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.

Parameters:

  | name | The name of the parameter to get

Returns:
  String value of parameter, blank if not found

virtual void Ogre::StringInterface::copyParametersTo | ( | StringInterface * | dest | ) | const`[virtual, inherited]`

Method for copying this object's parameters to another object.

Remarks:
  This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

  Any unrecognised parameters will be ignored as with setParameter method.

Parameters:

  | dest | Pointer to object to have it's parameters set the same as this object.

static void Ogre::StringInterface::cleanupDictionary | ( |  | ) | `[static, inherited]`

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

SubMeshList Ogre::Mesh::mSubMeshList`[protected]`

A list of submeshes which make up this mesh.

Each mesh is made up of 1 or more submeshes, which are each based on a single material and can have their own vertex data (they may not - they can share vertex data from the Mesh, depending on preference).

VertexData* Ogre::Mesh::sharedVertexData

Shared vertex data.

Remarks:
  This vertex data can be shared among multiple submeshes. SubMeshes may not have their own VertexData, they may share this one.

  The use of shared or non-shared buffers is determined when model data is converted to the OGRE .mesh format.

Definition at line 246 of file OgreMesh.h.

IndexMap Ogre::Mesh::sharedBlendIndexToBoneIndexMap

Shared index map for translating blend index to bone index.

Remarks:
  This index map can be shared among multiple submeshes. SubMeshes might not have their own IndexMap, they might share this one.

  We collect actually used bones of all bone assignments, and build the blend index in 'packed' form, then the range of the blend index in vertex data VES_BLEND_INDICES element is continuous, with no gaps. Thus, by minimising the world matrix array constants passing to GPU, we can support more bones for a mesh when hardware skinning is used. The hardware skinning support limit is applied to each set of vertex data in the mesh, in other words, the hardware skinning support limit is applied only to the actually used bones of each SubMeshes, not all bones across the entire Mesh.

  Because the blend index is different to the bone index, therefore, we use the index map to translate the blend index to bone index.

  The use of shared or non-shared index map is determined when model data is converted to the OGRE .mesh format.
