Name

cgSetTextureStateAssignment - sets a state assignment to a texture effect parameter

Synopsis

#include <Cg/cg.h>

CGbool cgSetTextureStateAssignment( CGstateassignment sa,
                                    CGparameter param );

Parameters

sa

A state assignment of type CG_TEXTURE.

param

An effect parameter of type CG_TEXTURE.

Return Values

Returns CG_TRUE if it succeeds in setting the state assignment.

Returns CG_FALSE otherwise.

Description

cgSetTextureStateAssignment sets the value of a state assignment of texture type to an effect parameter of type CG_TEXTURE.

Examples

CGparameter effectParam = cgCreateEffectParameter(effect,
                                                  "normalizeCube",
                                                  CG_SAMPLERCUBE);
CGstate state = cgGetNamedSamplerState(context, "Texture");
CGstateassignment sa = cgCreateSamplerStateAssignment(effectParam, state);
CGbool ok = cgSetTextureStateAssignment(sa, value);

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 texture 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

cgSetTextureStateAssignment was introduced in Cg 1.5.
