glsl - How to do ray tracing in modern OpenGL? - Stack …
https://stackoverflow.com/questions/3667218/how-to-do-ray-tracing-in-modern-opengl
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 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 ...

https://github.com/SingleZombie/Ray-Tracing-OpenGL
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. To learn more details about how to build the compiling environment, you can visit https://learnopengl.com/.
Raypicking / raytracing in OpenGL - Game Development Stack …
https://gamedev.stackexchange.com/questions/105798/raypicking-raytracing-in-opengl
Picking in an OpenGL based app, is usually done using external libraries to do the ray-casting. Usually a game has a Physics engine, which must be able to do a ray-cast, so most of the time the actual physics engine is used to do ray-casting. One of such libraries is bullet.
Raytracing in OpenGL via compute shader - Stack Overflow
https://stackoverflow.com/questions/15344282/raytracing-in-opengl-via-compute-shader
Ray r = {vec3 (0,0,0), vec3 (width/2-x, height/2-y, 1000)}; Since width, height, x and y are unsigned variables you will get problems when the term width/2-x becomes negative. This solves the problem: Ray r = {vec3 (0,0,0), vec3 (float (width)/2.0f-float (x), float (height)/2.0f-float (y), 1000)}; Share.
Raytracing support in OpenGL (equivalent of DXR)? - Khronos …
https://community.khronos.org/t/raytracing-support-in-opengl-equivalent-of-dxr/77016
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.
raytracing - Nvidia RTX ray tracing OpenGL extension - Game …
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
