LED style animation with MAXScript
Just illustration of an example approach which can be done and without writing code but there also a few points where using MAXScript can save alot of time.
Ok, this I start just as idea for quick reply into the forum but as I remember LED style animation is popular task in animators colleges and as am not sure if there is a similar tutorial, I made this.
The idea is to use "helper"-object(s) (any geometry) which to serve as a Brush, and with all the freedom of how you like/need to animate them, including not just there movement but also their size and shape, and according to the "intersection" between them and the "dots" (spheres in this video), animate the material ID's of this "dot"-objects.
No audio recorded but you can see what I typing into the Listener and what it produce in real time. I hope this video is useful anyway as is.
The code I typed is attached as well.
