I'm working on adding lighting to the FieldTrip library (ticket
http://trac.haskell.org/FieldTrip/ticket/16). I have some initial data types
I'm thinking that the GContext will keep track of which of the 8 opengl
lights are used and enable them if they are.
I was wondering what ideas folks have had with lighting. Some issues that
are on my mind:
- OpenGL limits the number of lights to 8.
- It would be nice, for a spotlight primitive, to allow the light's
position and a point it is pointing toward to go through different
transformations. This would allow a fixed light to follow an object, for
example. I don't know yet how to provide this functionality.
