Name

cgGLGetMatrixParameterArraydc - get the values from a matrix array parameter

Synopsis

#include <Cg/cgGL.h>

void cgGLGetMatrixParameterArraydc( CGparameter param,
                                    long offset,
                                    long nelements,
                                    double * v );

Parameters

param
The matrix array parameter from which the values will be retrieved.
offset
An offset into the array parameter at which to start getting elements. A value of 0 will begin at the first element of the array.
nelements
The number of elements to get. A value of 0 will default to the total number of elements in the array minus the value of offset.
v
The array into which to retrieve the values. The size of v must be nelements times the number of elements in the matrix.

Return Values

None.

Description

cgGLGetMatrixParameterArraydc retrieves an array of values from a matrix array parameter using column-major ordering.

Examples

to-be-written

Errors

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

CG_ARRAY_PARAM_ERROR is generated if param is not an array parameter.

CG_NOT_MATRIX_PARAM_ERROR is generated if the elements of param are not matrix parameters.

CG_OUT_OF_ARRAY_BOUNDS_ERROR is generated if offset or nelements is outside the bounds of param.

CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.

History

cgGLGetMatrixParameterArraydc was introduced in Cg 1.1.
