How to do ray tracing in modern OpenGL? - Stack Overflow
https://stackoverflow.com/questions/3667218/how-to-do-ray-tracing-in-modern-opengl
To answer the topic: OpenGL has no RTX extension, but Vulkan has, and interop is possible. Example here: https://github.com/nvpro-samples/gl_vk_raytrace_interop. As for the actual question: To light the triangles, there are tons of techniques, look up for "forward", "forward+" or "deferred" renderers. The technique to be used depends on you goal.
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 ...

OpenGL is not for raytracing. (Pedants here might say you can, but that's probably not how they want you do to your homework assignment.) 9. level 2. Zeliss. · 6y. When I took my graphics courses a few years ago, we had a graphics homework assignment which was to implement a ray-tracer using a fullscreen quad and a fragment shader. It's not ...

https://www.cse.msu.edu/~cse472/projects/raytrace-tutorial.html
The steps in the tutorial are: Step 1 - Create a simple scene graph. Step 2 - Using an Alternative Renderer. Step 3 - Examining COpenGLRender. Step 4 - Ray Trace Mode and Menu. Step 5 - Create An Image to Render To. Step 6 - Display the Ray Trace Image. Step 7 - Create a Renderer Class.
My Ray Tracing Tutorial : opengl
https://www.reddit.com/r/opengl/comments/hnzhej/my_ray_tracing_tutorial/
The first series covers building a simple ray tracer in GLSL. I just stumbled upon this reddit group and decided to share it with you. I hope some of you will find it useful, that would make me super happy. Currently, there are 4 parts, covering basic sphere-ray intersection, directional and point light, Phong shading, and reflections.

https://stackoverflow.com/questions/10909286/speed-of-ray-tracing-compared-to-e-g-opengl-or-other-graphics-implementation
For example, if you have a large number of spheres that you have stored in the right kind of search data structure, it will probably faster to shoot rays through the scene than to draw all the spheres that are in the view frustum on top of each other. GPUs do support ray-tracing algorithms now, and they have done so for several years. You usually have to implement the algorithms …
