Ray casting is faster because its world is limited by one or more geometric constraints (simple geometric shapes); a ray-tracing world can be almost any shape. Ray casting was developed in the...

Path tracing is a type of ray tracing. When using path tracing for rendering, the rays only produce a single ray per bounce. The rays do not follow a defined line per bounce (to a light, for example), 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.

All ray based techniques seem to revolve about casting rays through each pixel of an image which are supposed to represent rays of real light. This allows to render very realistic images. As a matter of fact I am making a simple program that renders such images myself based on Raytracing in one Weekend.

Ray casting is a process where points of intersection with a line are computed analytically, using formulas of intersection. Ray marching is a specific algorithm, a variant on ray casting where samples are taken down a line to test for intersections or other criteria.

However, ray-casting is the natural precursor to ray-tracing, as it tells us with what part of which object the ray intersects and provides all necessary information to cast subsequent rays. The vtkOBBTree Class

Fundamentally, Raycasting involves creating a ray and calculating what it hits (or if it hits a particular thing). Raytracing involves creating a ray and tracing its path as it reflects/refracts through the scene so that you can determine what light might arrive at its source from the other direction. Very simple, non-technical explanations...

Raytracing is the fastest but hardest of the three, while raycasting is the slowest and easiest, and raymarching has the advantage of being able to efficiently render 3d fractals and calculate a surface normal. And that's the end! Hope this helps :) Also, sorry for not really providing examples.

Ray casting Ray casting, as the original method of the other two variants, is a technique that transform a limited form of data (a very simplified map or floor plan) into a 3D projection by tracing rays from the view point into the viewing volume. Computation: Rays are cast and traced in groups based on some geometric constraints.
