Real-Time Simulation of Time-of-Flight Sensors via Path Tracing using OptiX
I have simulated a Time of Flight sensor by implementing a Path Tracing algorithm with NVIDIA OptiX. For this, I utilized current research to simulate surface properties physically correctly. Even if you're not interested in simulating sensors but only in physically accurate lighting, the article might be interesting for you.
Fundamentals of Photo Realistic Rendering
In this article I summarise the basics of physically based rendering. In particular, I look at the mathematical and physical principles that are necessary to understand global illumination.
