A method for efficiently manipulating 3D scenes recorded by a virtual camera using a computer system comprised of projectors, graphics accelerators, one or more CPUs, instances of 3D rendering software, and a MIDI interface, includes receiving from the MIDI controller camera parameters, defining left camera and right camera parameters based on the camera parameters, determining left and right images based upon left and right camera parameters, projecting left and right images, viewing left and right images, integrating left and right images to represent a 3D scene, manipulating the 3D scene until the user is satisfied, and storing the left and right camera parameters, and storing the left and right images.
