How the CINEMA 4D render engine works

A 3D render engine is a very complicated piece of software that's designed to simulate how …light and how cameras and how other types of objects behave in the real world. …Now when you hit the Render button in Cinema 4D, some very important things happen. …Now I have a simple scene here of a green light shining down on the sphere and I've …got a camera pointing at that, and I'm going to hit the Play button here in the interface. …Now when you hit the Render button, a couple of things happen. …The first thing that happens is, from the point of view of the camera and from the point of …view of the light source, …the render engine sends out these little mathematical probabilities called rays, and those rays …are designed to figure out what types of pixels are going to be drawn in the frame.…

Let's look through the camera by pressing the active Camera icon and we'll get this …cute little animation that pops us right into the point of view of the camera. …And you can see that from the camera's point of view, these lines represent the rays. …
