Abstract

Abstract In a computer graphics system, wherein three-dimensional data is processed to produce dynamic displays, two-dimensional texture images are sequentially mapped onto objects in the display to form movable animated figures. Objects receiving two-dimensional texture maps may be transparent and take specific forms for certain effects, for example, intersecting planes, stamps, moving objects, and so on. Texture maps are composed utilizing a variety of source devices including: computer graphics systems, video cameras, two-dimensional scanners.
