1. Field of the Invention
The present invention relates generally to 3D image production for stereoscopic motion pictures, and more specifically to the rendering and compositing stages in computer generated 3D image production.
2. Discussion of the Related Art
Computer generated imagery (CGI) is becoming more common for use in the production of stereoscopic motion pictures. Typically, large quantities of 3D computer models are rendered by render farms to produce two sets of 2D images, each set representing one of the stereo cameras required for stereoscopic viewing. These 2D images are then composited, for example, using a node based compositing tool to provide two final composited 2D images for each frame of the stereoscopic motion picture. The composited 2D images are then color corrected, further processed and edited for final production. Various techniques exist to project the final two cameras to the user such that the user visually interprets the illusion of depth.
