Abstract
A computer-implemented method for measuring the stereoscopic quality of a computer-generated object in a three-dimensional computer-generated scene. The computer-generated object is visible from at least one camera of a pair of cameras used for creating a stereoscopic view of the computer-generated scene. A set of surface vertices of the computer-generated object is obtained. A stereoscopic transformation on the set of surface vertices is computed to obtain a set of transformed vertices. A translation vector and a scale vector are computed and applied to the set of transformed vertices to obtain a ghosted set of vertices. The ghosted set of vertices is approximately translational and scale invariant with respect to the set of surface vertices. A sum of the differences between the set of surface vertices and the set of ghosted vertices is computed to obtain a first stereo-quality metric.
