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

Ray casting is a technique that transforms a limited form of data (a very simplified map or floorplan) into a 3D projection by tracing rays from the …

RAY-CASTING AND RAY-TRACING Like ray-casting, ray-tracing "determines the visibility of surfaces by tracing imaginary rays of light from viewer's eye to the object in the scene" (Foley 701). From both definitions, it seems that ray-casting and ray-tracing is the same. Indeed, some books use both terms interchangeably.

Unlike other forms of ray tracing, where rays originate from a light source and bounce off objects to arrive at the observer, in ray casting, they're "cast" directly from the viewpoint. When cast rays intersect an object, the object's color and brightness at that point determines the value of one pixel in the final image.

Raycasting is often used to project 2d maps onto a 3d screen, and has a variant called list-based raycasting where instead of moving a fixed step distance you move to the nearest edge of a grid until calculating an intersection. Raycasting is the simplest of …

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, ray tracing and ray marching all tend to be used interchangeably as a generalists catch-all term for a rendering process which relies on computed lines of intersection, but there are subtle distinctions implied when speaking precisely.
