Hi Thomas, The FixedFunctionTechnique also uses the OpenGL fixed function pipeline for doing the volume rendering and as a consequence is very limited in what effects it can render. The FixedFunctionTechnque is also something you'd use for very old hardware, The RayTracedTechnque is what you'd use for any modern computer.
