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 ...

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 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.
Accelerated Ray Tracing in One Weekend in CUDA - Developer …
https://forums.developer.nvidia.com/t/accelerated-ray-tracing-in-one-weekend-in-cuda/148615
Recent announcements of NVIDIA’s new Turing GPUs, RTX technology, and Microsoft’s DirectX Ray Tracing have spurred a renewed interest in ray tracing. Using these technologies vastly simplifies the ability to write applications using ray tracing. But what if you’re curious about how ray tracing actually works?

https://github.com/kwea123/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. NOTE: The code is not guaranteed to be fully optimized, but I intend to provide some insights on efficient python ...
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.
LITERATURE REVIEW: CUDA Accelerated Raytracing
https://gowtham-maran.github.io/Literature%20Review.pdf
For real-time applications, the Whitted algorithm [53] is the prominent ray tracing algorithm. There are many implementations of GPU ray traversal in earlier works. Purcell et al. [43] explained how a GPU ray tracing pipeline can be applied over a paradigm of stream programming. As an acceleration framework, they used a Uniform Grid, expanding ...
