In an apparatus and method for representing computer-modeled objects comprising a plurality of adjacent polygon surfaces, the image impression in the corner points of the polygon surfaces is calculated according to a local illumination model, whereas the image impression of the remaining pixels is interpolated according to the Gouraud shading method, and a color or brightness value is additionally calculated for simulating a surface structure for each pixel, the value taking into consideration the influence of the surface structure on the image impression without necessitating a complicated calculation of the local illumination model in each pixel.
