Since modern GPUs have great computational power as well as high memory bandwidth, running ray tracing on them has been an active field of research in computer graphics in recent years. Furthermore, the introduction of CUDA, a novel GPGPU architecture, has removed several limitations that the traditional GPU-based ray tracing suffered.

The default block size was 8x8x1. Increasing the block size to 16x16x1 gives us a black screen. This may be due to the limited memory size of the blocks.Adding more threads overloads the GPU and it will not run the code. Thus, we set the block size to 10x10x1. Increasing the block size allows more threads to be executed in parallel.
CUDA Real Time Ray Tracing Tutorial | Geeks3D
https://www.geeks3d.com/20090814/cuda-real-time-ray-tracing-tutorial/
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 Buffer Object). You can download source codes and executables here:

https://github.com/WilliamLewww/cuda_raytrace
cuda_raytrace contains a real-time ray-tracer engine that uses OpenGL's interoperability with CUDA. The ray-traced graphics are generated via CUDA which are then copied into a OpenGL texture. The texture is then applied to a quad that encompass the entire view-port. Dependencies CUDA (cuda-10.2) GLFW (glfw-3.3.2) GLEW (glew-2.1.0) GNU make Building
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 superior to a …

Accelerated Ray Tracing in One Weekend in CUDA
https://developer.nvidia.com/blog/accelerated-ray-tracing-cuda/
Chapter 1 in Ray Tracing in One Weekend ends with generating an image with a simple gradient for red & green channels. In a serial language, you use nested for loops to iterate over all of the pixels. In CUDA, the scheduler takes blocks of threads and schedules them on the GPU. But, before we get to that, we have to set up a few preliminaries…

Real-time raytracing in CUDA to find visible voxel objects.
https://www.youtube.com/watch?v=gvP9PWoYsuM
I'm testing the ray tracing technique to collect only visible objects from a large number of voxel objects. Even the CPU can work it, but it's too slow. So I implemented this in CUDA. This has been...
