%K direct volume rendering, gouraud shading, volumetric illumination.
%X Direct Volume Rendering algorithms are very important tools in the analysis of volumetric data in scientific visualization applications. Volume Shading is a critical step regarding the computational cost of these algortims. This paper presents a fast algorthm for volume shading. The proposed technique is based on decompositing the illumination equation into a sum of functions that can be pre-computed in look-up tables. Preliminary results showed the new algorithm is about six times faster than the conventional method.
