Abstract
We propose a material dependent volume illumination method that provides better reflective features of each material within the volume data. Our method can be applied to not only single light source but also environment lighting using prefiltered environment maps with diffuse and specular BRDFs (bidirectional reflectance distribution functions). In this case, multiple specular maps for each material are used in order to achieve material dependent reflections. As a result, our method provided fast prefiltering and real-time rendering speed while delivering material dependent illumination resulting in better reflection of observation and visualization.
