| Abstract: | Interpolation is a basic calculation for raycasting algorithm and has a lot of calculation,which directly influence the rendering speed.Tranditional trilinear interpolation costs a lot in the rendering process and many people have improved it.A new plane interpolation is proposed in this paper.It can obviously improve rendering speed,and the image quality of this new plane interpolation is acceptable. |
