OpenGL currently does not support hardware boosted Ray tracing. DirectX 12 on windows does have support for it. It is recommended to wait a few more years before creating a Ray tracing only renderer although it is possible using DirectX 12 with current desktop and laptop hardware. Support from mobile may take decades.

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.
How to do ray tracing in modern OpenGL?
https://newbedev.com/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/
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 following image:

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.

You really can't compare OpenGL and raytracing in that way. OpenGL is a rasterizer drawing API, i.e. it just puts single points, lines and triangles to the screen. There's no such thing like a scene or coherent geometric objects. Even if implemented in software, a rasterizer like OpenGL can be blazingly fast, quite easily.

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

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).

Set Ray Lenght. 1. Take the middle point of the ray. 2. Determine if that point is above of below the terrain 3. if the point is below the terrain take the upper half / else take the lower half of the ray 4. Repeat N times steps 1-4.
