Epipolar plane space subdivision method in stereoscopic ray tracing

This paper presents a novel space subdivision scheme based on epipolar geometry. It is particularly suited to stereoscopic ray tracing in the backprojection method. The resulting rendering algorithm gives a substantial speed improvement over generating stereo pair images separately, and the generated stereo images are effectively identical to those generated separately. In this work, the generation of stereoscopic images is accelerated by two methods, namely stereoscopic backprojection and epipolar plane-space subdivision. The performance of our algorithm is evaluated and compared with the octree algorithm. Experimental results demonstrating the efficiency of the approach are presented.
