Accelerated Ray Tracing in One Weekend in CUDA
https://developer.nvidia.com/blog/accelerated-ray-tracing-cuda/
int num_pixels = nx*ny; size_t fb_size = 3*num_pixels*sizeof(float); // allocate FB float *fb; checkCudaErrors(cudaMallocManaged( (void **)&fb, fb_size)); This call renders the image on the GPU and has the CUDA runtime divide the …

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.
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 …
An Implementation of Ray Tracing in CUDA
https://cseweb.ucsd.edu/~baden/classes/Exemplars/260_fa09/ChenDasPan_cse260_fa09.pdf
The pseudo code for our ray tracing algorithm is shown in Algorithm 1. The nal combined color Algorithm 1 Ray Tracing 1. for each pixel pixel in the image plane do 2. ... 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 ...

CUDA-Accelerated Ray Tracer Renderer - Nablax's page
https://nablax7.com/cuda-accelerated-ray-tracer-renderer/
After Learning the ray tracing in one weekend tutorial, I want to try to speed up the rendering with the help of GPU, I render the image with OpenGL with CUDA-OpenGL interop. To build a BVH tree in parallel, I implemented a so-called linear BVH based …
Ray Tracing - CUDA Programming and Performance - NVIDIA …
https://forums.developer.nvidia.com/t/ray-tracing/514
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.

Raytracing In One Weekend Series in C++, CUDA, and OptiX
https://github.crookster.org/raytracing-iow-in-cpp-cuda-and-optix/
One day, I found Peter Shirley’s Ray Tracing In One Weekend Book Series. I was able to implement my own copy of the code from his books, eventually also incorporating some versions using CUDA and Nvidia’s Optix 6.5 ray-tracing frameworks.. Low-noise render from the OptiX implementation. Building. The Cpp version is in portable, non-modern (that’s a GOOD …
