NAME
cgSetParameter4d - set the value of scalar and vector parametersSYNOPSIS
#include <Cg/cg.h>
void cgSetParameter4d( CGparameter param, double x, double y, double z, double w );
PARAMETERS
- param
- The parameter that will be set.
- x, y, z, w
- The values used to set param.
RETURN VALUES
None.DESCRIPTION
cgSetParameter4d sets the value of a given scalar or vector parameter.If more values are passed in than param requires, the extra values will be ignored.
Once cgSetParameter4d has been used to set a parameter, the values may be retrieved from the parameter using the CG_CURRENT enumerant with cgGetParameterValues.
If an API-dependant layer of the Cg runtime (e.g. cgGL) is used, these entry points may end up making API (e.g. OpenGL) calls.
EXAMPLES
to-be-writtenERRORS
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.CG_INVALID_PARAMETER_ERROR is generated if param is a varying input to a fragment program.
HISTORY
cgSetParameter4d was introduced in Cg 1.2.SEE ALSO
