Ray casting is considered the most basic of computer-graphics rendering algorithms and uses the geometric algorithm of ray tracing. The first ray-casting algorithm used for rendering was presented...

Ray Tracing Fundamentals. Ray casting is the process in a ray tracing algorithm that shoots one or more rays from the camera (eye position) through each pixel in an image plane, and then tests to see if the rays intersect any primitives (triangles) in the scene. If a ray passing through a pixel and out into the 3D scene hits a primitive, then the distance along the ray from the origin …

Raytracing, raymarching and raycasting are all different ways to render objects in a 3d space. Despite losing on speed to rasterizers or poly-filling, they have the advantage of being able to do accurate lighting, reflections, shadows, etc. that rasterizers …

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.

In CGI (computer-generated imagery), ray casting is the most basic form of raytracing. 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 …

That’s ray tracing. Ray tracing is eye-oriented process that needs walking through each pixel looking for what object should be shown there, which is also can be described as a technique that follows a beam of light (in pixels) from a set point and simulates how it reacts when it encounters objects.

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.

ray cast. is using raster image to hold the scene and usually stop on first hit (no reflections and ray splitting) and does not necessarily cast ray on per pixel basis (usually per row or column of screen). 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.
What is Ray Casting? - Definition from Techopedia
https://www.techopedia.com/definition/21614/ray-casting
Ray casting is distinct from ray tracing, with ray casting being a rendering algorithm which would never recursively trace secondary rays, while ray tracing is capable of doing so. Ray casting is also simple to use compared to other rendering algorithms such as ray tracing. Ray casting is fast, as only a single computation is needed for every vertical line of the screen. …
