Fragment Data

bindFragDataLocation :: Program -> String -> SettableStateVar DrawBufferIndex Source #

bindFragDataLocation binds a varying variable, specified by program and name, to a drawbuffer. The effects only take place after succesfull linking of the program. invalid arguments and conditions are - an index larger than maxDrawBufferIndex - names starting with gl_ linking failure will ocure when - one of the arguments was invalid - more than one varying varuable name is bound to the same index It's not an error to specify unused variables, those will be ingored.

getFragDataLocation :: Program -> String -> IO (Maybe DrawBufferIndex) Source #

query the binding of a given variable, specified by program and name. The program has to be linked. The result is Nothing if an error occures or the name is not a name of a varying variable. If the program hasn't been linked an InvalidOperation error is generated.
