Abstract: A user, through the use of an input device, provides signals indicative of x,y and z coordinates to a host central processing unit (CPU). The x,y and z coordinates provided by a user correspond to a desired viewpoint for the display of an object stored in an original data image memory. A graphics CPU is coupled to the host CPU for receipt of the x,y and z coordinates as well as to the original data image memory. The graphics CPU is further coupled to a program memory as well as two display buffers, each of which of comprises a bit map of points on the display. The graphics CPU, executing a rendering program stored in the program memory, renders (writes) the data comprising the object for the viewpoint corresponding to the x,y and z coordinates provided by the user.
