Name

cgGLGetMatrixParameter - get the values from a matrix parameter

Synopsis

#include <Cg/cgGL.h>

/* TYPE is float or double */

void cgGLGetMatrixParameter{fd}{rc}( CGparameter param,
                                     TYPE * matrix );

Parameters

param
The matrix parameter from which the values will be retrieved.
matrix
An array into which the values will be retrieved. The size must be the number of rows times the number of columns of param.

Return Values

None.

Description

The cgGLGetMatrixParameter functions retrieve the values from a matrix parameter.

There are versions of the function that return either float or double values signified by f or d in the function name.

There are versions of the function that assume the array of values is laid out in either row or column order signified by r or c respectively in the function name.

The cgGLGetMatrixParameter functions may only be called with uniform parameters.

Examples

to-be-written

Errors

CG_INVALID_PROFILE_ERROR is generated if param's profile is not a supported OpenGL profile.

CG_NOT_MATRIX_PARAM_ERROR is generated if param is not a matrix parameter.

CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.

History

The cgGLGetMatrixParameter functions were introduced in Cg 1.1.
