Ray casting computer graphics
WebRay casting is the use of ray-surface intersection tests to solve a variety of problems in computer graphics and computational geometry. The distinction is that ray casting is a rendering algorithm that never recursively traces secondary rays, whereas other ray tracing-based rendering algorithms may do so. Ray-marching is an implementation of a ...

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 … See more Ray casting is the most basic of many computer graphics rendering algorithms that use the geometric algorithm of ray tracing. Ray tracing-based rendering algorithms operate in image order to render three-dimensional … See more This figure shows an example of the binary operators in a composition tree using + and – where a single ray is evaluated. See more Ray casting qualifies as a brute force method for solving problems. The minimal algorithm is simple, particularly in consideration of its many applications and ease of use, but applications typically cast many rays.
