Advanced Illumination Techniques for GPU-Based Volume Raycasting

体可视化中的光照计算技术的权威论述-Volume raycasting techniques are important Abstract for both visual arts and

visualization. They allow an efficient generation of visual effects and

the visualization of scientific data obtained by tomography or numerical

simulation. Thanks to their flexibility, experts agree that GPU-based

raycasting is the state-of-the art technique for interactive volume rendering.

It will most likely replace existing slice-based techniques in the near

future. Volume rendering techniques are also effective for the direct rendering

of implicit surfaces used for soft body animation and constructive

solid geometry.
