## Detailed Description

Subclass of BillboardChain which automatically leaves a trail behind one or more Node instances.

Remarks:
  An instance of this class will watch one or more Node instances, and automatically generate a trail behind them as they move. Because this class can monitor multiple modes, it generates its own geometry in world space and thus, even though it has to be attached to a SceneNode to be visible, changing the position of the scene node it is attached to makes no difference to the geometry rendered.

  The 'head' element grows smoothly in size until it reaches the required size, then a new element is added. If the segment is full, the tail element shrinks by the same proportion as the head grows before disappearing.

  Elements can be faded out on a time basis, either by altering their colour or altering their alpha. The width can also alter over time.

  'v' texture coordinates are fixed at 0.0 if used, meaning that you can use a 1D texture to 'smear' a colour pattern along the ribbon if you wish. The 'u' coordinates are by default (0.0, 1.0), but you can alter this using setOtherTexCoordRange if you wish.

This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.

  You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.

Parameters:

  | constantEntry | The auto constant entry referring to the parameter being updated
  | params | The parameters object which this method should call to set the updated parameters.

virtual void Ogre::ShadowCaster::extrudeBounds | ( | AxisAlignedBox & | box,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist
| ) | const`[protected, virtual, inherited]`

Utility method for extruding a bounding box.

Parameters:

  | box | Original bounding box, will be updated in-place
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude

static void Ogre::ShadowCaster::extrudeVertices | ( | const HardwareVertexBufferSharedPtr & | vertexBuffer,
|  | size_t | originalVertexCount,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist
| ) | `[static, inherited]`

Utility method for extruding vertices based on a light.

Remarks:
  Unfortunately, because D3D cannot handle homogeneous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.

Parameters:

  | vertexBuffer | The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
  | originalVertexCount | The count of the original number of vertices, i.e. the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude

virtual void Ogre::ShadowCaster::generateShadowVolume | ( | EdgeData * | edgeData,
|  | const HardwareIndexBufferSharedPtr & | indexBuffer,

|  | unsigned long | flags
| ) | `[protected, virtual, inherited]`

Generates the indexes required to render a shadow volume into the index buffer which is passed in, and updates shadow renderables to use it.

Parameters:

  | edgeData | The edge information to use
  | indexBuffer | The buffer into which to write data into; current contents are assumed to be discardable.
  | light | The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing
  | shadowRenderables | A list of shadow renderables which has already been constructed but will need populating with details of the index ranges to be used.
  | flags | Additional controller flags, see ShadowRenderableFlags

virtual const String& Ogre::AnimableObject::getAnimableDictionaryName | ( | void |  | ) | const`[protected, virtual, inherited]`

| Returns the number of chain elements.

virtual unsigned short Ogre::Renderable::getNumWorldTransforms | ( | void |  | ) | const`[virtual, inherited]`

Returns the number of world transform matrices this renderable requires.

Remarks:

If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

Reimplemented in Ogre::BorderRenderable, Ogre::InstancedGeometry::GeometryBucket, and Ogre::SubEntity.

Real Ogre::BillboardChain::getSquaredViewDepth | ( | const Camera * | cam | ) | const`[virtual, inherited]`

Returns the camera-relative squared depth of this renderable.

Remarks:
  Used to sort transparent objects. Squared depth is used rather than actual depth to avoid having to perform a square root on the result.

Implements Ogre::Renderable.

virtual Technique* Ogre::Renderable::getTechnique | ( | void |  | ) | const`[virtual, inherited]`

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks:

virtual uint32 Ogre::MovableObject::getTypeFlags | ( | void |  | ) | const`[virtual, inherited]`

Get the 'type flags' for this MovableObject.

Remarks:
  A type flag identifies the type of the MovableObject as a bitpattern. This is used for categorical inclusion / exclusion in SceneQuery objects. By default, this method returns all ones for objects not created by a MovableObjectFactory (hence always including them); otherwise it returns the value assigned to the MovableObjectFactory. Custom objects which don't use MovableObjectFactory will need to override this if they want to be included in queries.

Reimplemented in Ogre::BillboardSet, Ogre::Entity, Ogre::Frustum, Ogre::Light, Ogre::ParticleSystem, and Ogre::StaticGeometry::Region.

bool Ogre::Renderable::getUseIdentityProjection | ( | void |  | ) | const`[inherited]`

Returns whether or not to use an 'identity' projection.

Remarks:
  Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this.

See also:
  Renderable::setUseIdentityProjection

Definition at line 168 of file OgreRenderable.h.

bool Ogre::Renderable::getUseIdentityView | ( | void |  | ) | const`[inherited]`

Returns whether or not to use an 'identity' view.

Remarks:
  Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this.

virtual const Sphere& Ogre::MovableObject::getWorldBoundingSphere | ( | bool | derive = `false` | ) | const`[virtual, inherited]`

| Retrieves the worldspace bounding sphere for this object. Reimplemented in Ogre::Entity.

void Ogre::BillboardChain::getWorldTransforms | ( | Matrix4 * |  | ) | const`[virtual, inherited]`

Gets the world transform matrix / matrices for this renderable object.

Remarks:
  If the object has any derived transforms, these are expected to be up to date as long as all the SceneNode structures have been updated before this is called.

  This method will populate xform with 1 matrix if it does not use vertex blending. If it does use vertex blending it will fill the passed in pointer with an array of matrices, the length being the value returned from getNumWorldTransforms.

Note:
  Internal Ogre never supports non-affine matrix for world transform matrix/matrices, the behavior is undefined if returns non-affine matrix here.

| ) | `[virtual, inherited]`

| Called immediately after the Renderable has been rendered. Definition at line 119 of file OgreRenderable.h.

virtual bool Ogre::Renderable::preRender | ( | SceneManager * | sm,
|  | RenderSystem * | rsys
| ) | `[virtual, inherited]`

Called just prior to the Renderable being rendered.

Remarks:
  OGRE is a queued renderer, so the actual render commands are executed at a later time than the point at which an object is discovered to be visible. This allows ordering & grouping of renders without the discovery process having to be aware of it. It also means OGRE uses declarative render information rather than immediate mode rendering - this is very useful in that certain effects and processes can automatically be applied to a wide range of scenes, but the downside is that special cases are more difficult to handle, because there is not the declared state to cope with it.

  This method allows a Renderable to do something special at the actual point of rendering if it wishes to. When this method is called, all the material render state as declared by this Renderable has already been set, all that is left to do is to bind the buffers and perform the render. The Renderable may modify render state itself if it wants to (and restore it in the postRender call) before the automated render happens, or by returning 'false' from this method can actually suppress the automatic render and perform one of its own.

Returns:
  true if the automatic render should proceed, false to skip it on the assumption that the Renderable has done it manually.

Definition at line 116 of file OgreRenderable.h.

virtual const LightList& Ogre::MovableObject::queryLights | ( | void |  | ) | const`[virtual, inherited]`

Gets a list of lights, ordered relative to how close they are to this movable object.

Remarks:
  By default, this method gives the listener a chance to populate light list first, if there is no listener or Listener::objectQueryLights returns NULL, it'll query the light list from parent entity if it is present, or returns SceneNode::findLights if it has parent scene node, otherwise it just returns an empty list.

  The object internally caches the light list, so it will recalculate it only when object is moved, or lights that affect the frustum have been changed (

  SceneManager::_getLightsDirtyCounter), but if listener exists, it will be called each time, so the listener should implement their own cache mechanism to optimise performance.

  This method can be useful when implementing Renderable::getLights in case the renderable is a part of the movable.

Returns:
  The list of lights use to lighting this object.

virtual void Ogre::BillboardChain::removeChainElement | ( | size_t | chainIndex | ) | `[virtual, inherited]`

Remove an element from the 'tail' of a chain.

Parameters:

  | chainIndex | The index of the chain

virtual void Ogre::RibbonTrail::removeNode | ( | Node * | n | ) | `[virtual]`

| Remove tracking on a given node.

virtual void Ogre::MovableObject::removeQueryFlags | ( | unsigned long | flags | ) | `[virtual, inherited]`

| As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object. Definition at line 350 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::removeVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

| As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object. Definition at line 378 of file OgreMovableObject.h.

virtual void Ogre::RibbonTrail::resetAllTrails | ( | void |  | ) | `[protected, virtual]`

| Reset all tracked chains to initial state.

virtual void Ogre::RibbonTrail::resetTrail | ( | size_t | index,
|  | const Node * | node
| ) | `[protected, virtual]`

| Reset the tracked chain to initial state.

void Ogre::MovableObject::setCastShadows | ( | bool | enabled | ) | `[inherited]`

Sets whether or not this object will cast shadows.

Remarks:
  This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.

Note:
  This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

Definition at line 456 of file OgreMovableObject.h.

virtual void Ogre::RibbonTrail::setColourChange | ( | size_t | chainIndex,
|  | Real | r,
|  | Real | g,
|  | Real | b,
|  | Real | a
| ) | `[virtual]`

Enables / disables fading the trail using colour.

Parameters:

  | chainIndex | The index of the chain
  | r,g,b,a | The amount to subtract from each colour channel per second

virtual void Ogre::RibbonTrail::setColourChange | ( | size_t | chainIndex,
|  | const ColourValue & | valuePerSecond
| ) | `[virtual]`

Enables / disables fading the trail using colour.

Parameters:

  | chainIndex | The index of the chain
  | valuePerSecond | The amount to subtract from colour each second

void Ogre::Renderable::setCustomParameter | ( | size_t | index,
|  | const Vector4 & | value
| ) | `[inherited]`

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks:
  Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.

Parameters:

  | index | The index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
  | value | The value to associate.

Definition at line 231 of file OgreRenderable.h.

virtual void Ogre::MovableObject::setDebugDisplayEnabled | ( | bool | enabled | ) | `[virtual, inherited]`

Sets whether or not the debug display of this object is enabled.

Remarks:
  Some objects aren't visible themselves but it can be useful to display a debug representation of them. Or, objects may have an additional debug display on top of their regular display. This option enables / disables that debug display. Objects that are not visible never display debug geometry regardless of this setting.

Definition at line 495 of file OgreMovableObject.h.

static void Ogre::MovableObject::setDefaultQueryFlags | ( | uint32 | flags | ) | `[static, inherited]`

virtual void Ogre::RibbonTrail::setInitialColour | ( | size_t | chainIndex,
|  | Real | r,
|  | Real | g,
|  | Real | b,
|  | Real | a = `1.0`
| ) | `[virtual]`

virtual void Ogre::MovableObject::setListener | ( | Listener * | listener | ) | `[virtual, inherited]`

Sets a listener for this object.

Remarks:
  Note for size and performance reasons only one listener per object is allowed.

Definition at line 396 of file OgreMovableObject.h.

virtual void Ogre::BillboardChain::setMaterialName | ( | const String & | name | ) | `[virtual, inherited]`

| Set the material name to use for rendering.

void Ogre::RibbonTrail::setMaxChainElements | ( | size_t | maxElements | ) | `[virtual]`

| Reimplemented from Ogre::BillboardChain.

void Ogre::RibbonTrail::setNumberOfChains | ( | size_t | numChains | ) | `[virtual]`

| Reimplemented from Ogre::BillboardChain.

virtual void Ogre::BillboardChain::setOtherTextureCoordRange | ( | Real | start,
|  | Real | end
| ) | `[virtual, inherited]`

Set the range of the texture coordinates generated across the width of the chain elements.

Parameters:

  | start | Start coordinate, default 0.0
  | end | End coordinate, default 1.0

virtual void Ogre::Renderable::setPolygonModeOverrideable | ( | bool | override | ) | `[virtual, inherited]`

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters:

  | override | true means that a lower camera detail will override this renderables detail level, false means it won't.

Definition at line 296 of file OgreRenderable.h.

virtual void Ogre::MovableObject::setQueryFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Sets the query flags for this object.

Remarks:
  When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

Definition at line 342 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderingDistance | ( | Real | dist | ) | `[virtual, inherited]`

Sets the distance at which the object is no longer rendered.

Parameters:

  | dist | Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

Definition at line 280 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderQueueGroup | ( | uint8 | queueID | ) | `[virtual, inherited]`

Sets the render queue group this entity will be rendered through.

Remarks:
  Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

  See RenderQueue for more details.

Parameters:

  | queueID | Enumerated value of the queue group to use.

Reimplemented in Ogre::Entity, and Ogre::ParticleSystem.

virtual void Ogre::Renderable::setRenderSystemData | ( | RenderSystemData * | val | ) | const`[virtual, inherited]`

gets render system private data

Remarks:
  This should only be used by a render system

Definition at line 364 of file OgreRenderable.h.

virtual void Ogre::BillboardChain::setTextureCoordDirection | ( | TexCoordDirection | dir | ) | `[virtual, inherited]`

Sets the direction in which texture coords specified on each element are deemed to run along the length of the chain.

Parameters:

  | dir | The direction, default is TCD_U.

virtual void Ogre::RibbonTrail::setTrailLength | ( | Real | len | ) | `[virtual]`

Set the length of the trail.

Remarks:
  This sets the length of the trail, in world units. It also sets how far apart each segment will be, ie length / max_elements.

Parameters:

  | len | The length of the trail in world units

virtual void Ogre::BillboardChain::setupBuffers | ( | void |  | ) | `[protected, virtual, inherited]`

virtual void Ogre::BillboardChain::setupChainContainers | ( | void |  | ) | `[protected, virtual, inherited]`

| Setup the STL collections.

virtual void Ogre::BillboardChain::setupVertexDeclaration | ( | void |  | ) | `[protected, virtual, inherited]`

| Setup vertex declaration.

void Ogre::Renderable::setUseIdentityProjection | ( | bool | useIdentityProjection | ) | `[inherited]`

Sets whether or not to use an 'identity' projection.

Remarks:
  Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this. The default is false.

See also:
  Renderable::getUseIdentityProjection

Definition at line 154 of file OgreRenderable.h.

void Ogre::Renderable::setUseIdentityView | ( | bool | useIdentityView | ) | `[inherited]`

Sets whether or not to use an 'identity' view.

Remarks:
  Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this. The default is false.

See also:
  Renderable::getUseIdentityView

Definition at line 179 of file OgreRenderable.h.

virtual void Ogre::Renderable::setUserAny | ( | const Any & | anything | ) | `[virtual, inherited]`

Sets any kind of user value on this object.

Remarks:
  This method allows you to associate any user value you like with this Renderable. This can be a pointer back to one of your own classes for instance.

Definition at line 315 of file OgreRenderable.h.

virtual void Ogre::MovableObject::setUserAny | ( | const Any & | anything | ) | `[virtual, inherited]`

Sets any kind of user value on this object.

Remarks:
  This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.

Note:
  This value is shared with setUserObject so don't use both!

Definition at line 310 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setUserObject | ( | UserDefinedObject * | obj | ) | `[virtual, inherited]`

Call this to associate your own custom user object instance with this MovableObject.

Remarks:
  By simply making your game / application object a subclass of UserDefinedObject, you can establish a link between an OGRE instance of MovableObject and your own application classes. Call this method to establish the link.

Definition at line 294 of file OgreMovableObject.h.

virtual void Ogre::BillboardChain::setUseTextureCoords | ( | bool | use | ) | `[virtual, inherited]`

Sets whether texture coordinate information should be included in the final buffers generated.

Note:
  You must use either texture coordinates or vertex colour since the vertices have no normals and without one of these there is no source of colour for the vertices.

virtual void Ogre::BillboardChain::setUseVertexColours | ( | bool | use | ) | `[virtual, inherited]`

Sets whether vertex colour information should be included in the final buffers generated.

Note:
  You must use either texture coordinates or vertex colour since the vertices have no normals and without one of these there is no source of colour for the vertices.

virtual void Ogre::MovableObject::setVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Sets the visiblity flags for this object.

Remarks:
  As well as a simple true/false value for visibility (as seen in setVisible), you can also set visiblity flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

Definition at line 370 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisible | ( | bool | visible | ) | `[virtual, inherited]`

Tells this object whether to be visible or not, if it has a renderable component.

Note:
  An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visibility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visibility changes are best done using this method; large or more longer term changes are best done by detaching.

Reimplemented in Ogre::Light.

virtual void Ogre::RibbonTrail::setWidthChange | ( | size_t | chainIndex,
|  | Real | widthDeltaPerSecond
| ) | `[virtual]`

Set the change in ribbon width per second.

|  | const Element & | billboardChainElement
| ) | `[virtual, inherited]`

Update the details of an existing chain element.

Parameters:

  | chainIndex | The index of the chain
  | elementIndex | The element index within the chain, measured from the 'head' of the chain
  | billboardChainElement | The details to set

virtual void Ogre::ShadowCaster::updateEdgeListLightFacing | ( | EdgeData * | edgeData,
|  | const Vector4 & | lightPos
| ) | `[protected, virtual, inherited]`

Tells the caster to perform the tasks necessary to update the edge data's light listing.

Can be overridden if the subclass needs to do additional things.

Parameters:

  | edgeData | The edge information to update
  | lightPos | 4D vector representing the light, a directional light has w=0.0

virtual void Ogre::BillboardChain::updateIndexBuffer | ( | void |  | ) | `[protected, virtual, inherited]`

| Update the contents of the index buffer.

virtual void Ogre::RibbonTrail::updateTrail | ( | size_t | index,
|  | const Node * | node
| ) | `[protected, virtual]`

| Node has changed position, update.

virtual void Ogre::BillboardChain::updateVertexBuffer | ( | Camera * | cam | ) | `[protected, virtual, inherited]`

| Update the contents of the vertex buffer.

void Ogre::BillboardChain::visitRenderables | ( | Renderable::Visitor * | visitor,
|  | bool | debugRenderables = `false`
| ) | `[virtual, inherited]`

Parameters:

  | visitor | Pointer to a class implementing the Renderable::Visitor interface which will be called back for each Renderable which will be queued. Bear in mind that the state of the Renderable instances may not be finalised depending on when you call this.
  | debugRenderables | If false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.
