Using vector subtraction to move a point onto a circle


Circles, spheres, and radii…

For a couple of reasons, I was playing around a bit with spherifying/circulizing this weekend:

Based on this basic idea: “every point on a sphere/circle is the same distance from the center”, I was able to rough-out a couple of ICE trees:


Creating a circle on the surface of a mesh required just a little bit of 3d vector math. Here’s a little video that goes over using vector subtraction to move a point onto a circle. I spent more time setting up the “Show Values” in my demo then I did recording the thing.
