The mental ray renderer can generate reflections and refractions by ray tracing. Ray tracing traces the path of rays sampled from the light source. Reflections and refractions generated this way are physically accurate.

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 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 …

-trace on|off Normally, mental ray will use a combination of a scanline rendering algorithm and ray tracing to calculate samples of the scene. If -trace off is specified, ray tracing is disabled, and mental ray will rely exclusively on the scanline algorithm.-trace_depth reflect int [refract int [sum int]] reflect limits the number of recursive reflection rays. If it is set to 0, no reflection rays will …
Path Tracing vs Ray Tracing - Dusterwald.com
https://www.dusterwald.com/2016/07/path-tracing-vs-ray-tracing/
So in ray tracing a ray is sent out from the virtual camera into the scene and traced until it intersects with a solid body. At this point a ray is cast to each of the light sources in the scene to calculate illumination and surface shading is calculated for the intersection point.
What is Path Tracing and Ray Tracing? And Why do They …

Path tracing provides a solution to that. When using path tracing for rendering, the rays only produce a single ray per bounce. The rays do not follow a set line per bounce, but rather shoot off in a random direction. The path tracing algorithm then takes a random sampling of all of the rays to create the final image.

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 …
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.
