Hi Haskellers,
I'm trying to generate a random vertex in OpenGL as follows.
genPosition :: IO (Vertex3 GLfloat)
genPosition = do x <- getStdRandom $ randomR (-1.6,1.6)
y <- getStdRandom $ randomR (-1.0,1.0)
return (Vertex3 x y (-1))
Unfortunately the compiler complains about me having to implement an instance
of Random for GLfloat.
How do I do this (or avoid having to do this)?
Cheers,
Mark
