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 ...
raytracing with CUDA - Stack Overflow
https://stackoverflow.com/questions/39473/raytracing-with-cuda
This problem, with the current state of the art in ray-tracing code, reduces your GPU utilization by a factor of 16-32, which may make performance unacceptable for your application, especially if it's real-time (e.g. a game). It still might be …

CUDA Path Tracer. Path tracing has long been the select method used by the graphics community to render photo-realistic images. It has found wide uses across several industries, and plays a major role in animation and filmmaking, with most special effects rendered using some form of Monte Carlo light transport.
Ray Tracing in One Weekend in CUDA - GitHub
https://github.com/rogerallen/raytracinginoneweekendincuda
Ray Tracing in One Weekend in CUDA. This is yet another Ray Tracing in One Weekend clone, but this time using CUDA instead of C++. CUDA can be used to speed up the code. For example, on my machine, the C++ code renders the test image in 90 seconds. The CUDA accelerated code renders the image in about 7 seconds.
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 ...
Nvidia CUDA Cores Explained: How are they different?
https://www.techcenturion.com/nvidia-cuda-cores/
CUDA cores; Tensor cores; Ray-Tracing cores; Each core is designed for a very specific purpose. Ray-Tracing cores are exclusive to Nvidia RTX graphics cards, and there are no GPUs from AMD that have Ray Tracing Cores. However, AMD’s upcoming RDNA 2 based GPUs will support Hardware Accelerated Ray Tracing.

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. 2. try to use more share memory. It is easy to do with the application I’m working, but I don’t think that you can easily use share memory in ray tracer.
