Name

cgGLGetParameterArray3d - get the values from an array parameter

Synopsis

#include <Cg/cgGL.h>

void cgGLGetParameterArray3d( CGparameter param,
                              long offset,
                              long nelements,
                              const double * v );

Parameters

param
The 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
Destination buffer into which the values will be written. The size of v must be 3 * nelements.

Return Values

None.

Description

cgGLGetParameterArray3d retrieves the values from a scalar or vector array parameter.

The function retrieves 3 values per array element.

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_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

cgGLGetParameterArray3d was introduced in Cg 1.1.
