ABSTRACT:
Image data representing multi-dimensional objects are processed, wherein the objects are represented by a plurality of polygons. Lighting characteristics for the polygons are calculated in response to data representing light sources and lighting parameters defining coefficients of specular reflection and diffuse reflection. Not all polygons have significant levels of specular reflection. Advantage is taken of this and the apparatus is arranged to process polygons having significant levels of specular reflection in accordance with a first process while processing other polygons in accordance with a second process.
