WebJun 9, 2024 · Raycasting is in effect, simply the first leg of the journey. In the example above, the first raycast is from the camera through the desired image until it intersects the scene object. In the above example, we can see the application of raytracing theory as a raycast simulation in a video game.

A typical 3D data set is a group of 2D slice images acquired by a CT, MRI, or MicroCT scanner. Usually these are acquired in a regular pattern (e.g., one slice for each millimeter of depth) and usually have a regular number of image pixels in a regular pattern.
