摘要
并行扫描转换算法,采用通过多边形顶点的扫描线对扫描转换区间进行划分,使划分在各个区域的子多边形都是梯形,这既在一定区域内保持了各种相关性,又消除了对奇点的处理,同时对梯形的扫描转换不需要求交计算而只进行增量计算,提高了扫描转换速度。
In this paper, the scan-line across the vertices of polygon was used to divide the data set in the parallel scan-conversion filling algorithm on Mesh-Connected Computer (MCC). This can reduce the computation of intersect-point and eliminate the oddpoint on the node processors. This also maintains every coherence which is used to improve the process speed in sequence algorithm.
