Name

cgGLSetParameter4fv - set the values of a scalar or vector parameter

Synopsis

#include <Cg/cgGL.h>

void cgGLSetParameter4fv( CGparameter param,
                          const float * v );

Parameters

param

The parameter that will be set.

v

Array of values used to set param.

Return Values

None.

Description

cgGLSetParameter4fv sets the values of a scalar or vector parameter from the given array of values.

If more values are passed in than the parameter requires, the extra values will be ignored.

cgGLSetParameter4fv may be called with either 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 v[] = {1.0f, 2.0f, 3.0f, 4.0f};

cgGLSetParameter4fv(param, &v);

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

cgGLSetParameter4fv was introduced in Cg 1.1.
