Raycast in Unity is a Physics function that projects a Ray into the scene, returning a boolean value if a target was successfully hit. When this happens, information about the hit, such as the distance, position or a reference to the object’s Transform, can be stored in a Raycast Hit variable for further use.

Does Doom use Raycasting?
Just to point out, Doom’s rendering engine is not a raycaster (as Wolfenstein 3D is) – that is, it doesn’t work by casting a ray for each column of the screen. Rather, it is a BSP engine. The geometry of the level is divided into a binary tree, and that tree is walked down to render the scene.
What is Monte Carlo rendering?
Path tracing is a computer graphics Monte Carlo method of rendering images of three-dimensional scenes such that the global illumination is faithful to reality. Fundamentally, the algorithm is integrating over all the illuminance arriving to a single point on the surface of an object.
Why is ray tracing better than rasterization?
Ray tracing can render accurate shadows, recursive reflections, refractions, and any reflected/bounced light. Rasterized rendering can’t do accurate shadows, recursive reflections, refractions, or any reflected/bounced light; with rasterized rendering you have to fake or skip these qualities.
Who created ray tracing?
The idea of ray tracing comes from as early as the 16th century when it was described by Albrecht Dürer, who is credited for its invention.
