摘要
插值算法是光线投射法中基本的计算方法,计算量很大,直接影响成像速度。传统的三元线性插值比较费时,许多人对其进行改进。本文提出一种平面插值算法,可以明显地提高成像速度并且图像质量仍可以接受。
Interpolation is a basic calculation for raycasting algorithm and has a lot of calculation, which directly influence the rendering speed. Tranditional trilinear interpolatian 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.
