Raytracing Render Switcher with Embree

We introduce a way of implementing physically-based renderers that can switch rendering methods with raytracing library. Various (PBR) generate beautiful images are close to human view real world. However, comparison between corresponding pairs pixels image generated by different is necessary verify whether the implementation correctly obeys mathematical models PBR. For comparison, result must be same scene, resolution, from camera angle. explain fundamental theory PBR first, and present overview library for PBR, Embree, developed Intel, as rendering-switchable implementation. Finally, we demonstrate computing renderer developed. The extended other method implementations.
