Abstract
Three-dimensional transition effects such as cross-fades between successive three-dimensional scenes are generated by manipulating depth (or 'Z') values as they transition over time in a series of transitional frames from the Z values associated with the first three-dimensional scene to the Z values associated with the second three-dimensional scene. In addition, a composition of two three-dimensional scenes is produced by first generating a pixel map of absolute differences between Z values of the two three-dimensional scenes, then blurring the pixel map, and finally blending color values of the two three-dimensional scenes according to a blending factor determined by the blurred pixel map values.
