NON-LINEAR DEPTH RENDERING OF STEREOSCOPIC ANIMATED IMAGES
First Claim
1. A computer-based method for rendering stereoscopic images, comprising:
- storing in memory a set of images comprising computer animated models;
operating a processor to position a pair of offset, virtual cameras for imaging the set of images; and
rendering the set of images with the processor based on a non-linear relationship between a disparity value assigned to at least one of the animated models and a distance between the cameras and the at least one of the animated models.

Abstract
A method for rendering stereoscopic images with non-linear depth variation The method includes storing content in memory that is ready for rendering, e.g., computer animated images including animated objects or models. A processor is operated to position stereo or horizontally offset cameras and to render the images based on a non-linear relationship between disparity assigned to one or more of the animated objects and a distance between the cameras and the objects. The non-linear relationship is defined by a function or algorithm callable by the processor such as a function that defines a curved depth variation for the computer animated scene. In other cases, the non-linear relationship is defined by stored table, and the rendering includes using the distance between the cameras and an object to retrieve the disparity value to assign to that object. More than one non-linear relationship may be used to render objects with differing depth variations.
