The ray-tracing problem is, given an optical system and the position and direction of an initial light ray, to decide if the light ray reaches some given final position. For many years ray tracing has been used for designing and analyzing optical systems. Ray tracing is now used extensively in computer graphics to render scenes with complex curved objects under global …
Ray tracing (graphics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(graphics)
Ray tracing (graphics) Not to be confused with Ray tracing (physics). This recursive ray tracing of reflective colored spheres on a white surface demonstrates the effects of shallow depth of field, "area" light sources, and diffuse interreflection. In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a ...

In this perspective, ray-tracing can characterize the channel in terms of Multi Path Components (MPCs) to provide a highly accurate model, at the price of extreme computational complexity (e.g., for processing detailed environment information about the propagation), which limits the scalability of the simulations.

graphics - Performance of Ray Tracing - Stack Overflow
https://stackoverflow.com/questions/13138841/performance-of-ray-tracing
A well-designed ray tracer will use acceleration datastructures that improve on the performance of a naive ray tracer. The general consensus is that performance can scale like log (scene complexity) per sample due to your acceleration structure -- although you also need to build and maintain the acceleration structure! – comingstorm.

7 Problems Raytracing Doesn't Solve
https://erikmcclure.com/blog/7-problems-raytracing-doesnt-solve/
Ray Tracing is an algorithm that constructs images based on a scientific model of cameras, lighting, a scene, and the optics involved. Depending on complexity of that model, Ray Tracing takes a very long time to compute, and modern hardware so far has been incapable to master that complexity in a sufficient degree to create real-time animations.

Reducing the O(n²) Time Complexity of a Ray Casting ...
https://stackoverflow.com/questions/45896293/reducing-the-on%c2%b2-time-complexity-of-a-ray-casting-algorithm
For example, using the ray tracing algorithm on a scene with 100.000 is still possible, but takes about ~10 minutes and that amount will exponentially increase when the scene consists of more triangles. Is there a way to reduce the time complexity to a lower complexity class without fundamentally changing the way the algorithm works?
