Abstract :
In this paper a new technique for ray tracing point-based models is presented. Our approach offers a higher ray tracing speed in comparison with previous methods. During pre-process, we add an important attribute to each point for the purpose of ray tracing. During rendering, an algorithm of intersecting a ray with point geometry is demonstrated to get satisfied results. Our approach makes it possible to render high quality ray traced images with global illumination. It performs well especially in the way of boundary representation. We have tested our idea for shadows, reflection and refraction.
