CGLab (since 2016.09) focuses on conducting research on photorealistic rendering, which includes a variety of optimization techniques for ray tracing. The main applications of photorealistic rendering are CG movies, animations, 3D games and immersive technology (AR and VR).
These are articles about the techniques I develop and lessons I learnt while toying or working with computer graphics. Most of it is self-taught and there's lots of reinventing the wheel (which I recommend) but also some innovative and new discoveries that often times are not documented anywhere else (and if any of this content becomes part of your paper or the center of your PhD thesis, I feel it'd be fair to mention this website).
