Ray Tracing Gems

Tomas Akenine-Moeller is a Distinguished Research Scientist at NVIDIA, Sweden, since 2016, and currently on leave from his position as professor in computer graphics at Lund University. Tomas couathored Real-Time Rendering and Immersive Linear Algebra, and has written 100+ research papers. Previously, he worked at Ericsson Research and Intel. Eric Haines currently works at NVIDIA on interactive ray tracing. He co-authored the books Real-Time Rendering, 4th Edition and An Introduction to Ray Tracing, edited The Ray Tracing News, and cofounded the Journal of Graphics Tools and the Journal of Computer Graphics Techniques. He is also the creator and lecturer for the Udacity MOOC Interactive 3D Graphics.
