ABSTRACT

Ray tracing and rasterization are often presented as a dichotomy. Since the early days of computer graphics, ray tracing has been the gold standard for visual realism. By allowing physically accurate simulation of light transport, ray tracing renders extremely high-quality images. Real-time rendering, on the other hand, is dominated by rasterization. In spite of being less physically accurate, rasterization can be accelerated by efficient, commonly available GPUs and has mature standardized programing interfaces.
