Name
cgSetParameter3d - set the value of scalar and vector parameters
Synopsis
#include <Cg/cg.h> void cgSetParameter3d( CGparameter param, double x, double y, double z );Parameters
- param
- The parameter that will be set.
- x, y, z
- The values used to set param.
Return Values
None.
Description
cgSetParameter3d sets the value of a given scalar or vector parameter.
If more values are passed in than param requires, the extra values will be ignored.
Once cgSetParameter3d has been used to set a parameter, the values may be retrieved from the parameter using the CG_CURRENT enumerant with cgGetParameterValues.
If an API-dependant layer of the Cg runtime (e.g. cgGL) is used, these entry points may end up making API (e.g. OpenGL) calls.
Examples
to-be-written
Errors
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
CG_INVALID_PARAMETER_ERROR is generated if param is a varying input to a fragment program.
History
cgSetParameter3d was introduced in Cg 1.2.
