实时显示直纹面拼接形体的方法探讨

Research on the Algorithm of Real-Time Generation of Making up Quadric Line-Vein Surfaces

以等灰度带理论为基础，提出了直纹面拼接体的快速生成算法。这种算法只需求出拼接体中一个图元的等灰度线，即可由相关性求出整个拼接体的等灰度线，大大提高了拼接体的图象生成速度。经理论分析和软件仿真本算法适合实时图象显示系统。

Based on equal-intensity line principle. a fast algorithm of making up quadric line-vein surfaces is presented. The algorithm only needs to calculate equal-intensity lines of one element so that all elements' equal-intensity lines can be gotten through the relation- ship of each other. Theoretic analysis and simulation prove that the algorithm is fast enough to generate images in real time.
