摘要： 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.

摘要： A computer-implemented method for computing an effective inter-ocular distance for a modeled viewer based on a maximum ocular divergence angle. A maximum ocular divergence angle, viewing distance, and an inter-ocular distance are obtained for the modeled viewer. An effective inter-ocular distance is computed based on the viewing distance, the inter-ocular distance, and the maximum ocular divergence angle. The effective inter-ocular distance represents the maximum positive parallax for the modeled viewer having the defined maximum ocular divergence angle. The effective inter-ocular distance may be used in a stereoscopic modeling system in place of the inter-ocular distance, the stereoscopic modeling system relating a set of parameters in a camera space to a set of parameters in viewer space. The stereoscopic modeling system may be a stereoscopic transformation.

摘要： A computer-implemented method for defining a range of bounding parameter values that satisfy perceptual constraints for a stereoscopically filmed computer-generated scene. A user selection of a bounding parameter from a set of scene parameters is selected. Values for scene parameters of the set of scene parameters that were not selected as the bounding parameter are obtained. A first bounding value for the bounding parameter is calculated based on a first perceptual constraint and based on the values of the scene parameters of the set of scene parameters that were not selected. A second bounding value for the bounding parameter is also calculated based on a second perceptual constraint and based on the values of the scene parameter of the set of scene parameters that were not selected. The first and second bounding values define a minimum and a maximum value of a range of values and are stored.
