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, wherein the disparity value defines a horizontal offset between a left eye image and a right eye image at the distance for the at least one of the animated models.
