A computer-implemented method for determining bounded-parallax constraints for the placement of a pair of stereoscopic cameras within a computer-generated scene. An initial near-parallax value is determined based on the focal length and a minimum scene depth. An initial far-parallax value is determined based on a focal length. A scaled near-parallax value and scaled far-parallax value are calculated based on the initial near-parallax value, initial far-parallax value, and a range of focal lengths. A creative near-parallax value is calculated based on a stereo-shift value and the product of a stereo-volume and the scaled near-parallax value. A creative far-parallax value is calculated based on the stereo-shift value and the product of the stereo-volume and the scaled far-parallax value. The creative near-parallax value and the creative far-parallax value are stored as the bounded-parallax constraints for the placement of the pair of stereoscopic cameras. |
