How to do ray tracing in modern OpenGL? - Stack Overflow
https://stackoverflow.com/questions/3667218/how-to-do-ray-tracing-in-modern-opengl
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
Introduction to Computer Graphics, Section 8.1 -- Ray Tracing
https://math.hws.edu/graphicsbook/c8/s1.html
8.1.2 Recursive Ray Tracing Basic ray casting can be used to compute OpenGL-style rendering and, with the addition of shadow rays, to implement shadows as well. More features can be implemented by casting a few more rays. The improved algorithm is called ray tracing. Consider specular reflection.

Show activity on this post. a few question regarding the ray tracing algorithm: Can anyone tell me please if I understood the algorithm ray tracing correctly? it gets the first object that intersects with the ray. (if there are no intersections it goes out) then if the object is reflective it sends recursively a reflection ray and compute the ...

The direction of the ray is calculated using the reflection equation R = 2 * (V * N) * N - V and the ray origin is merely the intersection point offset slightly by the normal of that point. The tracer function will continue to recursively call itself with new reflection rays up to two times, assuming the ray keeps reflecting with more surfaces.

CSE 472: The Big Honkin' Ray Tracing Tutorial
https://www.cse.msu.edu/~cse472/projects/raytrace-tutorial.html
When the program starts, it will display your model using OpenGL. When you select a Ray Trace menu option, it will create an image using your slow, but much cooler, renderer and display that image instead of the OpenGL rendering. Add a bool value to CChildView called m_raytrace and initialize it to false in the CChildView constructor.

Recursive Ray Tracing For realistic rendering, we need the following setup: an eye point E, a viewing screen S, and one or more point light sources with known location, color, and intensity (see Figure 1). We also need to specify the locations and the shapes of all the objects in the scene, together with their reflectivity, transparency, and ...
