NAME
cgGLSetParameterArray - sets an array scalar or vector parameters
SYNOPSIS
#include <Cg/cgGL.h> /* type is either float or double */ void cgGLSetParameterArray{1234}{fd}(CGparameter param, long offset, long nelements, const type *v);PARAMETERS
- param
Specifies the array parameter that will be set.
- offset
An offset into the array parameter to start setting from. A value of 0 will start setting from the first element of the array.
- nelements
The number of elements to set. A value of 0 will default to the number of elements in the array minus the offset value.
- v
The array of values to set the parameter to. This must be a contiguous set of values that total nelements times the vector size indicated by the number in the function name.
DESCRIPTION
The cgGLSetParameterArray functions set the value of a given scalar or vector array parameter. The functions are available in various combinations.
Each function will set either 1, 2, 3, or 4 values per array element depending on the function that is used.
There are versions of each function that take either float or double values signified by the f or d in the function name.
RETURN VALUES
The cgGLSetParameterArray functions do not return any values.
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 the offset and/or the nelements parameter are out of the array bounds.
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter handle.
CG_INVALID_PARAMETER_ERROR is generated if the parameter fails to set for any other reason.
