## Detailed Description

Collects together the program parameters used for a GpuProgram.

Remarks:
  Gpu program state includes constant parameters used by the program, and bindings to render system state which is propagated into the constants by the engine automatically if requested.

  GpuProgramParameters objects should be created through the GpuProgram and may be shared between multiple Pass instances. For this reason they are managed using a shared pointer, which will ensure they are automatically deleted when no Pass is using them anymore.

  High-level programs use named parameters (uniforms), low-level programs use indexed constants. This class supports both, but you can tell whether named constants are supported by calling hasNamedParameters(). There are references in the documentation below to 'logical' and 'physical' indexes; logical indexes are the indexes used by low-level programs and represent indexes into an array of float4's, some of which may be settable, some of which may be predefined constants in the program. We only store those constants which have actually been set, therefore our buffer could have gaps if we used the logical indexes in our own buffers. So instead we map these logical indexes to physical indexes in our buffer. When using high-level programs, logical indexes don't necessarily exist, although they might if the high-level program has a direct, exposed mapping from parameter names to logical indexes. In addition, high-level languages may or may not pack arrays of elements that are smaller than float4 (e.g. float2/vec2) contiguously. This kind of information is held in the ConstantDefinition structure which is only populated for high-level programs. You don't have to worry about any of this unless you intend to read parameters back from this structure rather than just setting them.

| Operator = overload.

void Ogre::GpuProgramParameters::setAutoConstant | ( | size_t | index,
|  | AutoConstantType | acType,
|  | size_t | extraInfo = `0`
| ) |

Sets up a constant which will automatically be updated by the system.

Remarks:
  Vertex and fragment programs often need parameters which are to do with the current render state, or particular values which may very well change over time, and often between objects which are being rendered. This feature allows you to set up a certain number of predefined parameter mappings that are kept up to date for you.

Parameters:

  | index | The location in the constant list to place this updated constant every time it is changed. Note that because of the nature of the types, we know how big the parameter details will be so you don't need to set that like you do for manual constants.
  | acType | The type of automatic constant to set
  | extraInfo | If the constant type needs more information (like a light index) put it here.

void Ogre::GpuProgramParameters::setAutoConstantReal | ( | size_t | index,
|  | AutoConstantType | acType,

| ) |

void Ogre::GpuProgramParameters::setConstant | ( | size_t | index,
|  | const int * | val,
|  | size_t | count
| ) |

Sets a multiple value constant integer parameter to the program.

Remarks:
  Different types of GPU programs support different types of constant parameters. For example, it's relatively common to find that vertex programs only support floating point constants, and that fragment programs only support integer (fixed point) parameters. This can vary depending on the program version supported by the graphics card being used. You should consult the documentation for the type of low level program you are using, or alternatively use the methods provided on RenderSystemCapabilities to determine the options.

Parameters:

  | index | The logical constant index at which to place the parameter (each constant is a 4D integer)
  | val | Pointer to the values to write, must contain 4*count ints
  | count | The number of groups of 4 ints to write

  | count | The number of groups of 4 floats to write

void Ogre::GpuProgramParameters::setConstant | ( | size_t | index,
|  | const Matrix4 * | m,
|  | size_t | numEntries
| ) |

Sets a list of Matrix4 parameters to the program.

Parameters:

  | index | The logical constant index at which to start placing the parameter (each constant is a 4D float). NB since a Matrix4 is 16 floats long, so each entry will take up 4 indexes.
  | m | Pointer to an array of matrices to set
  | numEntries | Number of Matrix4 entries

void Ogre::GpuProgramParameters::setConstant | ( | size_t | index,
|  | const Matrix4 & | m
| ) |

Sets a Matrix4 parameter to the program.

Parameters:

  | index | The logical constant index at which to place the parameter (each constant is a 4D float). NB since a Matrix4 is 16 floats long, this parameter will take up 4 indexes.
  | m | The value to set

void Ogre::GpuProgramParameters::setConstant | ( | size_t | index,
|  | const Vector3 & | vec
| ) |

Sets a 4-element floating-point parameter to the program via Vector3.

Parameters:

  | index | The logical constant index at which to place the parameter (each constant is a 4D float). Note that since you're passing a Vector3, the last element of the 4-element value will be set to 1 (a homogeneous vector)
  | vec | The value to set

void Ogre::GpuProgramParameters::setConstant | ( | size_t | index,
|  | Real | val
| ) |

Sets a single floating-point parameter to the program.

Note:
  This is actually equivalent to calling setConstant(index Vector4(val, 0, 0, 0)) since all constants are 4D.

Parameters:

  | index | The logical constant index at which to place the parameter (each constant is a 4D float)
  | val | The value to set

void Ogre::GpuProgramParameters::setConstant | ( | size_t | index,
|  | const Vector4 & | vec
| ) |

Sets a 4-element floating-point parameter to the program.

Parameters:

  | index | The logical constant index at which to place the parameter (each constant is a 4D float)
  | vec | The value to set

void Ogre::GpuProgramParameters::setConstantFromTime | ( | size_t | index,
|  | Real | factor
| ) |

Sets a named parameter up to track a derivation of the current time.

Parameters:

  | index | The index of the parameter
  | factor | The amount by which to scale the time value

void Ogre::GpuProgramParameters::setIgnoreMissingParams | ( | bool | state | ) |

| Tells the program whether to ignore missing parameters or not. Definition at line 1159 of file OgreGpuProgram.h.

void Ogre::GpuProgramParameters::setNamedAutoConstant | ( | const String & | name,
|  | AutoConstantType | acType,
|  | size_t | extraInfo = `0`
| ) |

Sets up a constant which will automatically be updated by the system.

Remarks:
  Vertex and fragment programs often need parameters which are to do with the current render state, or particular values which may very well change over time, and often between objects which are being rendered. This feature allows you to set up a certain number of predefined parameter mappings that are kept up to date for you.

Note:
  This named option will only work if you are using a parameters object created from a high-level program (HighLevelGpuProgram).

Parameters:

  | name | The name of the parameter
  | acType | The type of automatic constant to set
  | extraInfo | If the constant type needs more information (like a light index) put it here.

void Ogre::GpuProgramParameters::setNamedAutoConstantReal | ( | const String & | name,
|  | AutoConstantType | acType,
|  | Real | rData
| ) |

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | const int * | val,
|  | size_t | count,
|  | size_t | multiple = `4`
| ) |

Sets a multiple value constant floating-point parameter to the program.

  Some systems only allow constants to be set on certain boundaries, e.g. in sets of 4 values for example. The 'multiple' parameter allows you to control that although you should only change it if you know your chosen language supports that (at the time of writing, only GLSL allows constants which are not a multiple of 4).

Note:
  This named option will only work if you are using a parameters object created from a high-level program (HighLevelGpuProgram).

Parameters:

  | name | The name of the parameter
  | val | Pointer to the values to write
  | count | The number of 'multiples' of floats to write
  | multiple | The number of raw entries in each element to write, the default is 4 so count = 1 would write 4 floats.

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | const ColourValue & | colour
| ) |

Sets a ColourValue parameter to the program.

Parameters:

  | name | The name of the parameter
  | colour | The value to set

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | const double * | val,
|  | size_t | count,
|  | size_t | multiple = `4`
| ) |

Sets a multiple value constant floating-point parameter to the program.

  Some systems only allow constants to be set on certain boundaries, e.g. in sets of 4 values for example. The 'multiple' parameter allows you to control that although you should only change it if you know your chosen language supports that (at the time of writing, only GLSL allows constants which are not a multiple of 4).

Note:
  This named option will only work if you are using a parameters object created from a high-level program (HighLevelGpuProgram).

Parameters:

  | name | The name of the parameter
  | val | Pointer to the values to write
  | count | The number of 'multiples' of floats to write
  | multiple | The number of raw entries in each element to write, the default is 4 so count = 1 would write 4 floats.

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | const float * | val,
|  | size_t | count,
|  | size_t | multiple = `4`
| ) |

Sets a multiple value constant floating-point parameter to the program.

  Some systems only allow constants to be set on certain boundaries, e.g. in sets of 4 values for example. The 'multiple' parameter allows you to control that although you should only change it if you know your chosen language supports that (at the time of writing, only GLSL allows constants which are not a multiple of 4).

Note:

Parameters:

  | name | The name of the parameter
  | val | Pointer to the values to write
  | count | The number of 'multiples' of floats to write
  | multiple | The number of raw entries in each element to write, the default is 4 so count = 1 would write 4 floats.

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | const Matrix4 * | m,
|  | size_t | numEntries
| ) |

Sets a list of Matrix4 parameters to the program.

Parameters:

  | name | The name of the parameter; this must be the first index of an array, for examples 'matrices[0]' NB since a Matrix4 is 16 floats long, so each entry will take up 4 indexes.
  | m | Pointer to an array of matrices to set
  | numEntries | Number of Matrix4 entries

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | const Matrix4 & | m
| ) |

Sets a Matrix4 parameter to the program.

Parameters:

  | name | The name of the parameter
  | m | The value to set

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | const Vector3 & | vec
| ) |

Sets a Vector3 parameter to the program.

Note:
  This named option will only work if you are using a parameters object created from a high-level program (HighLevelGpuProgram).

Parameters:

  | index | The index at which to place the parameter NB this index refers to the number of floats, so a Vector3 is 3. Note that many rendersystems & programs assume that every floating point parameter is passed in as a vector of 4 items, so you are strongly advised to check with RenderSystemCapabilities before using this version - if in doubt use Vector4 or ColourValue instead (both are 4D).
  | vec | The value to set

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | const Vector4 & | vec
| ) |

Sets a Vector4 parameter to the program.

Parameters:

  | name | The name of the parameter
  | vec | The value to set

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | int | val
| ) |

Sets a single value constant integer parameter to the program.

Remarks:
  Different types of GPU programs support different types of constant parameters. For example, it's relatively common to find that vertex programs only support floating point constants, and that fragment programs only support integer (fixed point) parameters. This can vary depending on the program version supported by the graphics card being used. You should consult the documentation for the type of low level program you are using, or alternatively use the methods provided on RenderSystemCapabilities to determine the options.

  Another possible limitation is that some systems only allow constants to be set on certain boundaries, e.g. in sets of 4 values for example. Again, see RenderSystemCapabilities for full details.

Note:
  This named option will only work if you are using a parameters object created from a high-level program (HighLevelGpuProgram).

Parameters:

  | name | The name of the parameter
  | val | The value to set

void Ogre::GpuProgramParameters::setNamedConstant | ( | const String & | name,
|  | Real | val
| ) |

Sets a single value constant floating-point parameter to the program.

void Ogre::GpuProgramParameters::setNamedConstantFromTime | ( | const String & | name,
|  | Real | factor
| ) |

Sets a named parameter up to track a derivation of the current time.

Note:
  This named option will only work if you are using a parameters object created from a high-level program (HighLevelGpuProgram).

Parameters:

  | name | The name of the parameter

void Ogre::GpuProgramParameters::setTransposeMatrices | ( | bool | val | ) |

Sets whether or not we need to transpose the matrices passed in from the rest of OGRE.

Remarks:
  D3D uses transposed matrices compared to GL and OGRE; this is not important when you use programs which are written to process row-major matrices, such as those generated by Cg, but if you use a program written to D3D's matrix layout you will need to enable this flag.
