Abstract :
In this paper a point rendering system for ray tracing is presented. An oriented planar patch which passes a surface point is used to approximate the vicinity of that point. This paper defines a new point attribute for the purpose of efficiently locating the intersection between incoming ray and surface points. Accordingly, an algorithm of intersecting a ray with point geometry is proposed. The algorithm can gain a higher rendering speed in comparison with previous methods and has been demonstrated to get satisfied rendering results. The point rendering system deals well with shadow, reflection and refraction.
