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 ...

GPU ray tracing with CUDA
https://dc.ewu.edu/cgi/viewcontent.cgi?article=1093&context=theses
graphical data calculation. By redesigning the recursive ray tracing algorithm to use iterative loops, ray tracing can be parallelized on the GPU's multiple cores and this results in a considerable gain in the rendering speeds of ray tracers. 1.1 Ray Tracing Ray tracing is a powerful rendering method consisting of a series of simple algorithms ...
Writing A Ray Tracer using CUDA | Brent’s Website
https://retroscience.net/ray-tracing-with-cuda.html
What took the CPU (1 thread) over 30 seconds to render, I was able to get CUDA to render in ~20 milliseconds. There are plenty of places on the internet to learn how to write a ray tracer, so that is exactly what I did, I found one online and learned about making a lambert, metal, and glass material ray tracer (with some configurable values). I had 1 problem with what I learned, the …

An Implementation of Ray Tracing in CUDA
https://cseweb.ucsd.edu/~baden/classes/Exemplars/260_fa09/ChenDasPan_cse260_fa09.pdf
CUDA is potentially suitable for this job: GPUs have hundreds of cores which can trace the lights of the pixels simultaneously. Therefore, a naive approach to parallelize the problem in GPU is creating a ... ray tracing, the key observation is that the color in an image most likely changes gradually from pixel to pixel. For example, in Figure 2 ...
Ray Tracing - CUDA Programming and Performance - NVIDIA …

My code on ATI is faster than my unopimized code on CUDA. The reason is my program had a lot of memory dependence, Here is what I did to improve: 1. Use texture cache. If your data structures is read only, just bind them to a texture cache. ( for my case , a linear texture cache) It just works, fast and easy. or.
Optimizing Raytracing Algorithm Using CUDA

Raytracing: This method can simulate actual reflection a ray on objects, and generate realistic images. In these images, reflection, refraction, absorption, and shadow are represented well, and after a ray intersect object, also rays of light are computed. In this method, generating images is costly and depend on depth number of a ray of light [3].
