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.

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.

Parameters
indexThe 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.
acTypeThe type of automatic constant to set
extraInfoIf the constant type needs more information (like a light index) put it here.
void Ogre::GpuProgramParameters::setAutoConstant ( size_t  index,
AutoConstantType  acType,

const Vector2 vec 
)

Sets a 4-element floating-point parameter to the program via Vector2.

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.

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

Sets a multiple value constant boolean 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
nameThe name of the parameter
valPointer to the values to write
countThe number of 'multiples' of floats to write
multipleThe number of raw entries in each element to write, the default is 4 so count = 1 would write 4 floats.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.

void Ogre::GpuProgramParameters::setNamedConstant ( const String name,
uint  val 
)

Sets a single value constant unsigned 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
nameThe name of the parameter
valThe value to set
void Ogre::GpuProgramParameters::setNamedConstant ( const String name,
const Vector4 vec 
)

Parameters
nameThe name of the parameter
valThe value to setSets a Vector4 parameter to the program.
nameThe name of the parameter
vecThe 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
indexThe 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).
vecThe value to set
void Ogre::GpuProgramParameters::setNamedConstant ( const String name,
const Vector2 vec 
)

Sets a Vector2 parameter to the program.

Parameters
nameThe name of the parameter
vecThe value to set
void Ogre::GpuProgramParameters::setNamedConstant ( const String name,
const Matrix4 m 
)

Sets a Matrix4 parameter to the program.

Parameters
nameThe name of the parameter
mThe value to set
void Ogre::GpuProgramParameters::setNamedConstant ( const String name,
const Matrix4 m,
size_t  numEntries 
)

Sets a list of Matrix4 parameters to the program.

Parameters
nameThe 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.
mPointer to an array of matrices to set
numEntriesNumber of Matrix4 entries
void Ogre::GpuProgramParameters::setNamedConstant ( const String name,
const ColourValue colour 
)

Sets a ColourValue parameter to the program.

Parameters
nameThe name of the parameter
colourThe value to set
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
This named option will only work if you are using a parameters object created from a high-level program (HighLevelGpuProgram).
Parameters
nameThe name of the parameter
valPointer to the values to write
countThe number of 'multiples' of floats to write
multipleThe 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 double *  val,
size_t  count,
size_t  multiple = 4 
)

Sets a multiple 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
nameThe name of the parameter
factorThe amount by which to scale the time value
void Ogre::GpuProgramParameters::setNamedSubroutine ( const String subroutineSlot,
const String subroutine 
)

Set subroutine name by slot name.

void Ogre::GpuProgramParameters::setSubroutine ( size_t  index,
const String subroutine 
)

Set subroutine name by slot index.

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

Gets the physical buffer index associated with a logical bool constant index.

Note
Only applicable to low-level programs.
Parameters
logicalIndexThe logical parameter index
requestedSizeThe requested size - pass 0 to ignore missing entries and return std::numeric_limits<size_t>::max()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.
