| 摘 要： | 提出等值面直接显示算法，充分利用数据空间的相关性，把体素分为边界体素和内部体素，并采用体数据边界表示法，降低了内存。绘制等值面时，将视线与边界体素的求交运算转化为对离散视线上点的扫描，避开对整个体数据空间的遍历，从而减少了计算量。

| Abstract: | An accelerated direct rendering algorith of isosurface for 3D data sets is presented.The problem for calculating the intersections of the ray and the bounding cells pierced by the isosurface can be viewed as the problem of sampling alonga 3D discreteray.It is shown that the algorithm is better on memory requirement and speed than traditional algorithm through its realization on PC. |
