摘要： A computer-implemented method determining a user-defined stereo effect for a computer-generated scene. A set of bounded-parallax constraints including a near-parallax value and a far-parallax value is obtained. A stereo-volume value is obtained, wherein the stereo-volume value represents a percentage of parallax. A stereo-shift value is also obtained, wherein the stereo-shift value represents a distance across one of: an area associated with a camera sensor of a pair of stereoscopic cameras adapted to film the computer-generated scene; and a screen adapted to depict a stereoscopic image of the computer-generated scene. A creative near-parallax value is calculated based on the stereo-shift value, the stereo-volume, and the near-parallax value. A creative far-parallax value is also calculated based on the stereo-shift value and the product of the stereo-volume and the far-parallax value. The creative near-parallax value and creative far-parallax value are stored in a computer memory as the user-defined stereo effect.

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.

The computer-generated scene includes a pair of stereoscopic cameras adapted to capture an image of at least one computer-generated object and the window object. A left portion and right portion of the image along the left and right edges of the image are obtained. The nearest computer-generated object to the pair of stereoscopic cameras within the left and right portions of the image is identified. The window object is placed between the identified computer-generated object and the stereoscopic cameras at an offset distance from the identified computer-generated object.

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： Bounded-parallax constraints are determined for the placement of a pair of stereoscopic cameras within a computer-generated scene. A minimum scene depth is calculated based on the distance from the pair of cameras to a nearest point of interest in the computer-generated scene. A near-parallax value is also calculated based on the focal length and the minimum scene depth. Calculating the near-parallax value includes selecting a baseline stereo-setting entry from a set of stereo-setting entries, each stereo-setting entry of the set of baseline stereo-setting entries includes a recommended scene depth, a recommended focal length, and a recommended near-parallax value. For the selected baseline stereo-setting entry: the recommended scene depth corresponds to the minimum scene depth, and the recommended focal length corresponds to the focal length. The near-parallax value and far-parallax value are stored as the bounded-parallax constraints for the placement of the pair of stereoscopic cameras.

摘要： A computer-implemented method for smoothing a stereo parameter for a computer-animated film sequence. A timeline for the film sequence is obtained, the timeline comprising a plurality of time entries. A stereo parameter distribution is obtained, wherein the stereo parameter distribution comprises one stereo parameter value for at least two time entries of the plurality of time entries, and wherein the stereo parameter value corresponds a stereo setting associated with a pair of stereoscopic cameras configured to produce a stereoscopic image of the computer-animated film sequence. Depending on a statistical measurement of the stereo parameter distribution, either a static scene parameter is calculated, or a set of smoothed parameter values is calculated.
