ABSTRACT:
A method for generating realistic images using discrete representations employs a discrete voxel based representation of the scene within a three-dimensional (3-D) Cubic Frame Buffer of infinitesimal voxels. Each voxel stores information corresponding to the attributes of that portion of the scene. Numerous sight rays are traversed through the Cubic Frame Buffer. When a non-transparent infinitesimal voxel is encountered by a traversing sight ray, a hit is recognized. The attributes of that portion of the object that is encountered are then used for generating secondary rays. Depending upon the number and characteristics of the secondary rays that are generated, an appropriate representation of the scene can be generated from any viewing direction.
