Efficient image-based rendering of volume data
Jae-Jeong Choi, Yeong Gil Shin · 2002
The paper presents an efficient image based rendering algorithm of volume data. Using intermediate image space instead of image space, mapping becomes more efficient and holes coming from the point-to-point mapping can be removed. Mapping in intermediate image space is easily performed by looking up the table with the depth value of a source pixel. We also suggest a way of minimizing space requirement for pre-acquired images. Experimental results show that the algorithm can generate 25-40 images per second without noticeable image degradation in the case of making 256/sup 2/ images with a 256/sup 3/ voxel data set.
