Reducing Render Time in Ray Tracing by Pixel Averaging

Abstract

Many computer graphics rendering algorithms and techniques use ray tracing for generatingnatural and photo-realistic images. Ray tracing is a method to convert 3D-modeles into 2D-high quality images by complex computation. The millions of rays must be simulated and traced to create realistic image. A method for reducing render time is acceleration structures. The kd -tree is the most commonly used in accelerating ray tracing algorithms. This paper has focused on reducing render time. We propose tow methods that are combined with ray tracing method for obtaining some pixel colour of image plane . Our methods are linear algorithm and arefaster than ray tracing method. Our results show that our methods are at least 50% faster than spatial median approach for reasonably complex scenes with around 70k polygons and about 0.2% quality degradation. In this article, we show that these proposal methods canbe combined with other ray tracing methodssuch as SAH to reduce render time.
