ABSTRACT:
A data processing system provides high performance three-dimensional graphics. In one embodiment a processor of the data processing system performs a computer algorithm that creates a motion illusion regarding an object being displayed in a computer graphics scene by drawing multiple images of the object and varying the application of an attribute, such as transparency, color, intensity, reflectivity, fill, texture, size, and/or position including depth, to the images in a manner that provides the object with an illusion of three-dimensional motion between a first position and a second position. Also described are an integrated circuit for implementing the motion illusion algorithm and a computer-readable medium storing a data structure for implementing the motion illusion algorithm.
