ABSTRACT:
A video effects system comprises a graphics generator for generating a three-dimensional image in simulated real time, a digital video effects device for generating a second image and transforming the second image in real time, and a depth combiner for combining the three-dimensional image with the transformed second image to produce an output image that is the intersection of the three-dimensional image and the transformed second image.
