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 ...
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 …
CUDA Real Time Ray Tracing Tutorial | Geeks3D
https://www.geeks3d.com/20090814/cuda-real-time-ray-tracing-tutorial/
Here is a nice tutorial about how to code a real time ray tracer using CUDA. 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 ...

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 ...

of ray tracing is to simulate re ections, refractions, and shadows, which are di cult using other algorithms. The computation can be naturally paralellized due to the independency among pixels. 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 ...
Optimizing Raytracing Algorithm Using CUDA
https://gowtham-maran.github.io/Optimizing%20Raytracing%20Algorithm%20Using%20CUDA.pdf
generate image using raytracing algorithm to run on CPU or GPU in multi-thread algorithm. GPU This algorithm employs light with depth of 8 to generate images. It is optimized by changing pixel travel priority and ray of light to thread, dedicating depth function to empty threads, and using optimized functions from MSDN library.
