Abstract

Texture-mapping hardware has been successfully exploited for volume rendering. In this paper, we combine splatting method with 2D texture mapping efficiently and propose an algorithm for footprint algorithm based volume rendering accelerated by multi texture mapping. First of all, a regular data set is divided by some texture slices along the primary viewing direction. Then the segmented data are projected to the texture slices plane. Lastly, all these texture slices compose the final image by blending. With our algorithm, the scaled volume data set can be rendered effectively and fast but not degrade the quality of image remarkably.
