| 1. A method of identifying an absence of image information when generating a complementary stereoscopic image pair, the method
comprising:
projecting at least a portion of a first 2D image comprising image information onto computer-generated geometry from a first
camera having a first viewing frustum at a first camera location;
designating a second camera having a second viewing frustum at a second camera location, wherein the second viewing frustum
includes at least a portion of the computer-generated geometry;
determining depth values associated with the image information in the first viewing frustum and in the second viewing frustum,
wherein each of the depth values indicates a distance between one of the cameras and a point in the projected first 2D image
in the viewing frustum for the associated camera; and
identifying an absence of valid image information in a stereoscopic image corresponding to the first 2D image by comparing
the depth values for corresponding points of the projected first 2D image in the first and second viewing frustums.
