Name

cgGLSetParameter1d - set the values of a scalar or vector parameter

Synopsis

#include <Cg/cgGL.h>

void cgGLSetParameter1d( CGparameter param,
                         double x );

Parameters

param

The parameter that will be set.

x

The value to which param will be set.

Return Values

None.

Description

cgGLSetParameter1d sets the value of a scalar or vector parameter.

cgGLSetParameter1d 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

double x = 1.0;

cgGLSetParameter1d(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

cgGLSetParameter1d was introduced in Cg 1.1.
