more specific than light sourcing which is simply changing the colour
intensity of a surface appropriate to its orientation relative to a
source of light.
Everyone will probably have heard of Gouraud shading (linear
interpolation of colour intensity across a surface giving a rounded
appearance). Specular reflection effects are based on Phong shading,
the inner workings of which are described in most University level
computer graphics textbooks. Phong shading is computationally very
expensive compared to Gouraud shading, and GP2 will probably be the
first commercial computer game to have this effect. Just further proof
that Geoff Crammond is indeed God !
