What Is Path Tracing? | NVIDIA Blog

Path tracing simulates the true physics of light, which uses ray tracing as one component of a larger light simulation system. This would mean all lights in a scene are sampled stochastically — using Monte Carlo or other techniques — both for direct illumination, to light objects or characters, and for global illumination, to light rooms or environments with indirect …

Simply put, path tracing is a more advanced form of ray tracing which relies upon simulating the path of light by bouncing back on a single pixel …

Path tracing is a type of ray tracing. It falls under that umbrella, but where ray tracing was originally theorized in 1968, path tracing didn’t come onto the scene until 1986 (and the results were not as dramatic as those now.) Remember the exponential increase in rays mentioned earlier? Path tracing provides a solution to that.
Basics about path tracing · A Graphics Guy's Note
https://agraphicsguynotes.com/posts/basics_about_path_tracing/
Path tracing is a type of ray tracing algorithm which solves the rendering equation very well. And it is unbiased and consistent which means that as the number of samples increases per-pixel, the result is heading for the physically correct value. It is simple and easy to implement once you have mastered the math behind it.
WebGL Path Tracing - Made by Evan
https://madebyevan.com/webgl-path-tracing/
Path tracing is a realistic lighting algorithm that simulates light bouncing around a scene. This path tracer uses WebGL for realtime performance and supports diffuse, mirrored, and glossy surfaces. The path tracer is continually rendering, so the scene will start off grainy and become smoother over time.

https://www.gamesradar.com/forget-ray-tracing-nvidia-calls-path-tracing-one-of-the-largest-breakthroughs-for-real-time-graphics-in-many-years/
In short, path tracing is a big step up from ray tracing technology now used with PC and console games. We still think of ray tracing as being the pinnacle of …
Path Tracing vs Ray Tracing - Dusterwald.com

Path Tracing vs Ray Tracing. July 4, 2016 Sebastian. Path tracing is all the rage in the offline rendering space these days. From Cycles to SuperFly (based on the open source Cycles) to Octane, most new rendering engines seem to be using this technology. Sometimes referred to as “unbiased, physically correct rendering” what is path tracing, how is it different to …
Monte Carlo Path Tracing
http://www.graphics.stanford.edu/courses/cs348b-01/course29.hanrahan.pdf
1.2 Monte Carlo Path Tracing First, let’s introduce some notation for paths. Each path is terminated by the eye and a light. E - the eye. L - the light. Each bounce involves an interaction with a surface. We characterize the interac-tion as either reflection or tranmission. There are different types of reflection and transmission functions.
