Name
cgGLSetMatrixParameterArrayfr - set the values of a matrix array parameter
Synopsis
#include <Cg/cgGL.h> void cgGLSetMatrixParameterArrayfr( CGparameter param, long offset, long nelements, const float * v );Parameters
- param
- The matrix array parameter that will be set.
- offset
- An offset into the array parameter at which to start setting elements. A value of 0 will begin at the first element of the array.
- nelements
- The number of elements to set. A value of 0 will default to the total number of elements in the array minus the value of offset.
- v
- The array of values to which to set the parameter. This must be a contiguous set of values with size nelements times the number of elements in the matrix.
Return Values
None.
Description
cgGLSetMatrixParameterArrayfr sets the value of a matrix array parameter from an array of floats laid out in row-major order.
Examples

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.
CG_INVALID_PARAMETER_ERROR is generated if the parameter fails to set for any other reason.
History
cgGLSetMatrixParameterArrayfr was introduced in Cg 1.1.
