Abstract :
A technique for displaying binary space partitioning (BSP) trees that is faster than the usual back-to-front display method is presented. By combining polygon scan-conversion with a dynamic screen data structure, the technique, a front-to-back approach, provides significant speedup in the display time of polygonal scenes that depend on BSP trees, especially in cases where the number of polygons is large. This speedup is confirmed by applying the technique to randomly generated triangles.<>
