Abstract

In this paper we present a method for accelerating volume rendering by judicious choice of the sample stepping distance. This distance is taken for convenience to be 1 unit in the standard algorithm, but the algorithm can be accelerated by adapting the distance to the view direction. Advantage can be taken of the fact that samples occur only on cube faces, and realistically the computational cost of the volume rendering algorithm is reduced by 50%, with very little image degradation. This method achieves an excellent balance between the image quality and computation time. The method involves very little extra computation to initiate, and works for arbitrary viewing directions.
