markbecker/OpenCL_Raytracer: A Raytracer utilizing …
https://github.com/markbecker/OpenCL_Raytracer
We designed and developed a ray tracer that demonstrates the OpenCL framework. A suite of benchmark tests were developed to compare relative run times. Benchmarks were run on these systems using native C code on the CPU, and OpenCL using both the CPU and GPU. The project had three main parts: building the ray tracer, utilizing the OpenCL
openCL ray tracing and branching kernel code issue
https://stackoverflow.com/questions/26186383/opencl-ray-tracing-and-branching-kernel-code-issue
Show activity on this post. So I'm trying to implement a ray/path tracer using openCL and it seems pretty straightforward - write a kernel that traces the path of a single ray/pixel/etc and have it execute on multiple rays in parallel. However, when traversing a scene, a single ray has a considerable number of directions it can take.
Realtime raytracing with OpenCL II - One man show - GameDev.net

We accept a ray, the scene and the depth at which we currently are in recursive tracing. The following code : void* intersectObj = 0; int intersectObjType = 0; float t = intersect( ray, scene, &intersectObj, &intersectObjType); finds the first intersection of the ray in the scene and returns a pointer to the object, as well the type of this object.

https://computergraphics.stackexchange.com/questions/7997/opencl-ray-tracer-which-is-better-geometry-code-on-device-side-or-on-host-side
In order to pass data to the device side, in OpenCL you must create the sphere structure on the device as well (that is in the kernel). So you first create your structures as classes or structs on the CPU. The variables in the structs should be of cl_* datatypes. OpenCL provides typedefs for all primitive data types.
Ray tracer in Rust and OpenCL - Alexey Gerasev
https://agerasev.github.io/2019/09/24/clay-ray-tracer.html
This post is about my attempt to write a simple physically-based Monte-Carlo ray tracing engine in Rust and OpenCL. It is aimed to be a convenient framework for toy experiments with ray tracing, so the main goals was modularity and extendability, and also performance was taken into account. ... (source code). It is written in C++ and OpenCL and ...
