Effects of Digitizing Ray-based 3-D Visual Data

Abstract

Ray-based representation of 3-D visual data is on the assumption that 4-D ray parameters, which represent the position of passing point and direction, are regarded as analog data. In this paper, we examine the effects of digitization of 4-D ray parameters. In such condition, ray data is chosen incorrectly when new image is synthesized, which causes local distioritions in synthsized image.
