Yay! Robert over at Flight404 was kind enough to give me some pointers as to what I needed to do to get my Perlin flow field experiment working using Daniel Shiffman’s excellent Vector3D library. This is a first example. It’s simplistic and not terribly interesting visually, but it’s a start.
I’ve been trying to do this ever since I saw Robert’s magnetosphere video months and months ago, and I’m cheered up by finally making it work, in a simple way.
