Abstract
By growing power and flexibility of modern GPU, hardware based volume rendering techniques show their great powers in accelerating rendering. In this paper, we propose a 3D texture base algorithm with local phong lighting model. It load medical image series as volume data, then creates 3D texture from the volume data, then setups and renders proxy-geometry to sample 3D texture. Phong model is used for local light effect. Finally, composites sampled values and uses transfer function to map data value to final color value. We also implement this algorithm and analyze its performance.
