Synopsis

- param
- The parameter that will be set.
- x
- The value to which param will be set.
Return Values

Description
cgSetParameter1f sets the value of a given scalar or vector parameter.
Once cgSetParameter1f 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
cgSetParameter1f was introduced in Cg 1.2.
