As for 2019 Ray tracing is an option for real time rendering but requires high end GPUs most users don't have. Some of these GPUs are designed specifically for Ray tracing. OpenGL currently does not support hardware boosted Ray tracing. DirectX 12 on windows does have support for it.

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/.

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.

OpenGL ray tracing. This is a program I made that is pretty cool if you ask me! When it's compressed it's only 46 kilobytes. It uses ray tracing to calculate the colour of each pixel.

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

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.

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.

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.
