<p>Parallactic changes in the appearance of a surface are simulated using texture mapping. When an image is computed, more than one texture is mapped to the same surface. The coordinate maps of those textures are shifted relative to each other when the viewpoint from which the surface is viewed changes. One texture is normally shown on a pixel of the surface, unless indicates a 'transparent' state for that pixel, in which case the other texture is shown.</p> |
