Detailed Description

Predefined controller value for setting a single floating- point value in a constant paramter of a vertex or fragment program.

Remarks:

Any value is accepted, it is propagated into the 'x' component of the constant register identified by the index. If you need to use named parameters, retrieve the index from the param object before setting this controller up.

Note:

Retrieving a value from the program parameters is not currently supported, therefore do not use this controller value as a source, only as a target.
