Accelerated Ray Tracing in One Weekend in CUDA
https://developer.nvidia.com/blog/accelerated-ray-tracing-cuda/
The C++ ray tracing engine in the One Weekend book is by no means the fastest ray tracer, but translating your C++ code to CUDA can result in a 10x or more speed improvement! Let’s walk through the process of converting the C++ code from Ray Tracing in One Weekend to CUDA. Note that as you go through the C++ coding process, consider using git ...

README.md python-ray-tracing-with-cuda-example An example of cuda ray tracing in pure python syntax. It reproduces the result of Ray Tracing in One Weekend The original cpp code takes around 4 hours to complete, while this python CUDA implementation takes less than 1 minute.
raytracing with CUDA - Stack Overflow

For instance, imagine all 32 highly-coherent rays bouncing off a sphere. They will all go in fairly different directions after this bounce, and will probably hit objects made out of different materials, with different lighting conditions, and so forth.
CUDA Real Time Ray Tracing Tutorial | Geeks3D
https://www.geeks3d.com/20090814/cuda-real-time-ray-tracing-tutorial/
This tutorial is focused on sending a ray into a loaded triangulated model, computing the first hit position and do simple light calculations. It shows how to send the mesh data to CUDA via CUDA 1D texture or how to communicate between OpenGL and CUDA via PBO (Pixel Buffer Object). You can download source codes and executables here:

An Implementation of Ray Tracing in CUDA
https://cseweb.ucsd.edu/~baden/classes/Exemplars/260_fa09/ChenDasPan_cse260_fa09.pdf
For example, the \ray casting"[1] shoots rays from the viewpoint and nds the closest object that intersects the ray. Ray casting does not trace the rays further. The advantage of ray tracing is that it traces the lights bouncing among objects, which allows a much more realistic simulation of lighting over other rendering methods.

GPU ray tracing with CUDA
https://dc.ewu.edu/cgi/viewcontent.cgi?article=1093&context=theses
Ray Tracing is a rendering method that generates high quality images by simulating how light rays interact with objects in a virtual scene. The ray tracing technique can accurately portray advanced optical effects, such as reflections, refractions, and shadows, but at a greater computational cost and rendering time than other rendering methods.
