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

So, you have three possibities. Pure raytracing. Render only a fullscreen quad, and in your fragment shader, read your scene description packed in a buffer (like a texture), traverse the hierarchy, and compute ray-triangles intersections. Hybrid 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.

The shader authoring path for Vulkan is GLSL cross-compiled to SPIR-V, so the addition of GLSL_NVX_raytracing and SPV_NVX_raytracing is consistent with the addition of VK_NVX_raytracing.
opengl - Ray tracing via Compute Shader vs Screen Quad
https://stackoverflow.com/questions/44181875/ray-tracing-via-compute-shader-vs-screen-quad
This is important when you're tracing a complex scene. If your scene is trivial (e.g., Cornell Box), then the difference is negligible. Trace some spheres in your fragment shader all day long. Check http://shadertoy.com/ to witness the madness that can be achieved with modern GPUs and fragment shaders. But.
opengl - Problems implementing a screen space shadow ray …
https://gamedev.stackexchange.com/questions/44758/problems-implementing-a-screen-space-shadow-ray-tracing-shader
Here I previously asked for the possibility of ray tracing shadows in screen space in a deferred shader. Several problems were pointed out. One of the most important problem is that only visible objects can cast shadows and objects between the camera and the shadow caster can interfere. Still I thought it'd be a fun experiment.
Raytracing: Shader Optimisation Question : opengl
https://www.reddit.com/r/opengl/comments/uhlnbg/raytracing_shader_optimisation_question/
I am creating a single shader that performs raytracing. It takes in various shapes (spheres, cylinders, etc) as separate SSBOs and tests against these to determine the ray colour. Nothing shocking, I suspect. My naive implementation has the raytracer performing intersection code against all shapes for each ray.
