Opengl and glsl can be used for both ray and path tracing if you are really good at it. however there are few other better options like Nvidia optix with Cuda toolkit, directx 12, vulkan ray tracing, metal, falcor. Note that, all these are low level APIs that could be good performance with Nvidia recent rtx technology and support multi gpus Share

OpenGL is a rasterizer. Forcing it to do raytracing is possible, but difficult. This is why raytracing is not "ideal for real time graphics in a few years". In a few years, only hybrid systems will be viable. So, you have three possibities. Pure raytracing.

Ray-Tracing-OpenGL A OpenGL implement of ray tracing running on GPU. To compile the project, you need to add some extra files: Add glad.c to your project. Add glad, glfw, glm to include path. Add opengl32.lib , glfw3.lib to additional dependency.

In the OpenGL ES ray tracing API, rays are emitted via a programmable stage called the Frame Shader. In a G-buffer hybrid renderer, a frame shader instance runs for each G-buffer pixel. The object data stored in the G-buffer is used to initialize zero-to-many rays per-pixel.
Ray tracing with OpenGL Compute Shaders (Part I)
https://blog.lwjgl.org/ray-tracing-with-opengl-compute-shaders-part-i/
Dec 8, 2014 • 1 min read. An excellent first part article/tutorial of a series on 'Ray tracing with OpenGL Compute Shaders' by Kai Burjack. Its pretty rare to find good tutorials covering such topics especially using modern OpenGL techniques. By the end of the tutorial series its expected that you'll be able to produce cool results like the ...

c++ - opengl ray tracing and mesh - Stack Overflow
https://stackoverflow.com/questions/31195937/opengl-ray-tracing-and-mesh
Usually, in ray tracing, we have objects such as sphere, cylinder, plane (triangle), and torus for which we have a closed form function and we can find their intersection with rays. For complicated objects like bunny, ray is casted and intersected with a collection of planes (triangles). Share Improve this answer answered Jul 3, 2015 at 3:56
raytracing - Nvidia RTX ray tracing OpenGL extension
https://gamedev.stackexchange.com/questions/165971/nvidia-rtx-ray-tracing-opengl-extension
Is your question whether or not OpenGL headers exist for the RTX extension? It appears it can only be accessed through NVIDIA OptiX, DXR, and Vulkan. From the website: Developers can access NVIDIA RTX ray tracing through the NVIDIA OptiX application programming interface, through Microsoft’s DirectX Raytracing API (DXR) and Vulkan. Share
Raytracing support in OpenGL (equivalent of DXR)?
https://community.khronos.org/t/raytracing-support-in-opengl-equivalent-of-dxr/77016
I asked 2 different NVidia guys at SIGGRAPH this year (one of which was presenting on “NVidia RTX on Vulkan” in the NVidia booth), and both said that there are no plans to support the raytracing capability from OpenGL. (RTX being the new GPU line which has the new RT cores – for HW-accelerated ray tracing support – in addition to CUDA ...
OpenGL - Will it ever have RTX Raytracing support?
https://community.khronos.org/t/opengl-will-it-ever-have-rtx-raytracing-support/104489
Do your ray tracing in Vulkan, and then use Vulkan/GL interop to interact with that code from your GL app. The “OpenGL” quiz question at the SIGGRAPH 2019 Khronos BOF was actually spent on this, believe it or not, and the prize was a GPU Ray Tracing book (a capability which requires Vulkan or DXR to get at).
