Ray casting is faster than ray tracing. Ray casting is faster because its world is limited by one or more geometric constraints (simple geometric shapes); a ray …

Ray tracing is a more complex series of tasks which uses ray casting and/or ray marching to compute not only the point of intersection between origin and object surface (or voxel cell etc) but which iteratively computes secondary and tertiary rays, which can be used to collect data used typically (but not exclusively) for calculation of reflected or refracted light.

Same idea as ray casting except once you hit a triangle you reflect on it and go into a different direction. The number of reflection you allow is the “depth” of your ray tracing. The color of the pixel can be calculated, based off the light source and all the polygons it had to reflect off of to get to that screen pixel.

The 3D version of this is called Voxel space ray cast however the map is not voxel space instead 2 raster images RGB,Height are used. For more info see: ray cast; Voxel space ray casting (back) ray trace. This usually follows physical properties of light so ray split in reflected and refracted and we stop usually after some number of hits.

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...

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.
Ray casting - Wikipedia
https://en.wikipedia.org/wiki/Ray_casting
Ray casting is the methodological basis for 3D CAD/CAM solid modeling and image rendering. It is essentially the same as ray tracing for computer graphics where virtual light rays are "cast" or "traced" on their path from the focal point of a camera through each pixel in the camera sensor to determine what is visible along the ray in the 3D scene. The term "Ray Casting" was introduced …

Ray tracing captures those effects by working back from our eye (or view camera) — a technique that was first described by IBM’s Arthur Appel, in 1969, in “ Some Techniques for Shading Machine Renderings of Solids .”. It traces the path of a light ray through each pixel on a 2D viewing surface out into a 3D model of the scene.
