Detailed Description

A group of manually updated parameters that are shared between many parameter sets.

Remarks:: Sometimes you want to set some common parameters across many otherwise different parameter sets, and keep them all in sync together. This class allows you to define a set of parameters that you can share across many parameter sets and have the parameters that match automatically be pulled from the shared set, rather than you having to set them on all the parameter sets individually.

: Parameters in a shared set are matched up with instances in a GpuProgramParameters structure by matching names. It is up to you to define the named parameters that a shared set contains, and ensuring the definition matches.

Note:: Shared parameter sets can be named, and looked up using the GpuProgramManager.

void Ogre::GpuSharedParameters::removeAllConstantDefinitions ( )

Remove a constant definition from this shared set of parameters.

void Ogre::GpuSharedParameters::removeConstantDefinition ( const String & name )

Remove a constant definition from this shared set of parameters.

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

Sets a single value constant floating-point 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::GpuSharedParameters::setNamedConstant	(	const String &	name,
		int	val
	)

Sets a single value constant integer 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:

name	The name of the parameter
val	The value to set

void Ogre::GpuSharedParameters::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::GpuSharedParameters::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:

name	The name of the parameter
vec	The value to set

void Ogre::GpuSharedParameters::setNamedConstant	(	const String &	name,
		const Vector2 &	vec
	)

Sets a Vector2 parameter to the program.

Parameters:

name	The name of the parameter
vec	The value to set

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

Sets a Matrix4 parameter to the program.

Parameters:

name	The name of the parameter

void Ogre::GpuSharedParameters::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
