Name
cgGLSetParameter1f - set the values of a scalar or vector parameter
Synopsis
#include <Cg/cgGL.h> void cgGLSetParameter1f( CGparameter param, float x );Parameters
- param
- The parameter that will be set.
- x
- The value to which param will be set.
Return Values
None.
Description
cgGLSetParameter1f sets the value of a scalar or vector parameter.
cgGLSetParameter1f may be called with uniform or varying parameters. When called with a varying parameter, the appropriate immediate mode OpenGL entry point will be called. However, the cgGLGetParameter functions only work with uniform parameters.
Examples
float x = 1.0f; cgGLSetParameter1f(param, x);Errors
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 the parameter fails to set for any other reason.
History
cgGLSetParameter1f was introduced in Cg 1.1.
