| Abstract: | The technique of volume rendering is a kind of volume visualisation technique, which can reflect the inside information of the data. This paper introduces three kinds of algorithm for volume rendering: ray-casting algorithm, splatting algorithm and shear-warp algorithm. The differences of their performances are compared and their improvements are also discussed here. Then some results are presented and their perspective are given in the end. |
