The VISA+ hardware architecture is the first of a new generation of graphics accelerators designed primarily to render bump-, texture-, environment-and environment-bump-mapped polygons. This paper presents examples of the main graphical capabilities and discusses methods and simplifications used to create high quality images. One of the key concepts in the(More)
Today's high-end Gouraud renderers produce nicely textured scenes by mapping two-dimensional images onto modeled objects in real· time. We present a renderer which textures surfaces in the normal sense of the word using bump textures to simulate wrinkled or dimpled color­ ful surfaces. Using a simplified bump mapping method we first suc­ ceeded in designing(More)
