摘要：In order to achieve flexible 3-D visual communication, we have proposed a light ray based describing method of 3-D images. Furthermore, we have proposed a new concept of “3-D Space Coding” to describe and transmit the entire visual data of a 3-D space. Because the amount of spatial data is huge, it must be compressed for transmission and for easy handling by computers. In order to synthesize an image from one viewpoint, it is not necessary that all of the compressed data are expanded. Only the data essential for each view should be expanded. In this paper, the concept of “3-D Space Coding” is explained and a method for expanding the compressed light ray data locally is discussed in detail. Experimental results show the potential applicability of the proposed method to deal with larger space by local expansion of compressed light ray data.
