NVIDIA RTX Ray Tracing | NVIDIA Developer
https://developer.nvidia.com/rtx/ray-tracing
Ray tracing is a method of graphics rendering that simulates the physical behavior of light. Thought to be decades away from reality, NVIDIA has made real-time ray tracing possible with NVIDIA RTX™ the first-ever real-time ray-tracing GPU—and has continued to pioneer the technology since. Powered by NVIDIA RT Cores, ray tracing adds unmatched beauty and …

On the later chapters, the CUDA code uses M_PI constant in the camera.h code. Please add the following snippet before the camera.h include so there are no build-time errors: #ifndef M_PI #define M_PI 3.14159265358979323846 #endif. Again, thanks for your contribution. I will tinker with the code so I can learn ray tracing better. Have a great day!

DX12 Raytracing tutorial - Part 1 | NVIDIA Developer
https://developer.nvidia.com/rtx/raytracing/dxr/dx12-raytracing-tutorial-part-1
By Martin-Karl Lefrançois and Pascal Gautron # NVIDIA DXR Sample Welcome to Part 1 of the DirectX 12 DXR ray tracing tutorial. The focus of these documents and the provided code is to showcase a basic integration of raytracing within an existing DirectX 12 sample, using the new DXR API. Note that for educational purposes all the code is contained in a very small set of files.
