Name
cgSetSamplerStateAssignment - sets a state assignment to a sampler effect parameter.
Synopsis
#include <Cg/cg.h> CGbool cgSetSamplerStateAssignment( CGstateassignment sa, CGparameter param );Parameters
- sa
- A state assignment of a sampler type (one of CG_SAMPLER1D, CG_SAMPLER2D, CG_SAMPLER3D, CG_SAMPLERCUBE, or CG_SAMPLERRECT).
- param
- An effect parameter of a sampler type.
Return Values
Returns CG_TRUE if it succeeds in setting the state assignment.
Returns CG_FALSE otherwise.
Description
cgSetSamplerStateAssignment sets a state assignment of a sampler type to an effect parameter of the same sampler type.
Examples
CGparameter effectParam = cgCreateEffectParameter(effect, "normalizeCube", CG_SAMPLERCUBE); CGstate state = cgGetNamedSamplerState(context, "TextureCubeMap"); CGstateassignment sa = cgCreateStateAssignment(technique, state); CGbool ok = cgSetSamplerStateAssignment(sa, effectParam);Errors
CG_INVALID_STATE_ASSIGNMENT_HANDLE_ERROR is generated if sa is not a valid state assignment.
CG_STATE_ASSIGNMENT_TYPE_MISMATCH_ERROR is generated if sa is not a state assignment of a sampler type.
CG_ARRAY_SIZE_MISMATCH_ERROR is generated if sa is an array and not a scalar.
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
History
cgSetSamplerStateAssignment was introduced in Cg 1.5.
