Abstract

A method for simultaneous generation of stereoscopic images of implicitly defined surfaces is presented. Ray tracing, a computationally intensive but `photo-realistic'' rendering technique, is used to generate these images. Traditional ray tracing of stereoscopic images involves generating left eye and right eye images separately, which effectively doubles the computational work involved. A method originally developed for animation and later adopted for stereo ray tracing achieves computational speedup in ray tracing stereoscopic images by generating the right eye image as the left eye image is generated. The work presented here extends that method to obtain stereoscopic images of implicitly defined surfaces of the form f(x,y,z) equals 0. Implicitly defined quadric surfaces such as spheres, ellipsoids, hyperboloids of one sheet and two sheets, and surfaces derived from fault-tolerant software modeling applications were rendered using this method. The speedups achieved for these surfaces under different stereoscopic setups are compared and tabulated.
