creativMotion has been going through the C4D Xpresso nodes one by one, offering some insights into how they operate. Each time, there is a practical example of how you would use the nodes in Xpresso, and how you can re-create the node’s effects using Python.

Here, creativMotion has a look into the technical explanation of how Ray Collision node in Xpresso works and offers a practical example for how you might use it in your work. In the end, he covers a bit about how to use Ray Collision to draw on a curved surface in Cinema 4D.
