                         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.",
