NAME
cgGLSetupSampler - initializes a sampler's state and texture object handleSYNOPSIS
#include <Cg/cgGL.h>
void cgGLSetupSampler( CGparameter param, GLuint texobj );
PARAMETERS
- param
- The sampler parameter that will be set.
- texobj
- An OpenGL texture object name to which the parameter will be set.
RETURN VALUES
None.DESCRIPTION
cgGLSetupSampler initializes a sampler; like cgGLSetTextureParameter, it informs the OpenGL Cg runtime which OpenGL texture object to associate with the sampler. Furthermore, if the sampler was defined in the source file with a sampler_state block that specifies sampler state, this sampler state is initialized for the given texture object.Note that in order to use the texture, either cgGLEnableTextureParameter must be called after cgGLSetTextureParameter and before the geometry is drawn, or cgGLSetManageTextureParameters must be called with a value of CG_TRUE.
EXAMPLES
to-be-writtenERRORS
CG_INVALID_PROFILE_ERROR is generated if param's profile is not a supported OpenGL profile.CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
CG_INVALID_PARAMETER_ERROR is generated if param is not a texture parameter or if the parameter fails to set for any other reason.
HISTORY
cgGLSetupSampler was introduced in Cg 1.4.SEE ALSO
