It really is. I’d been through bits of it a few other times but I have trouble focusing on anything for long. But this time, I had a goal which compels a focus. I’m going to focus solely on everything I can do in vectors – and that’s a lot. Nothing else.

I’ll get to Quaterions – I swear I will. I understand them intuitively and I know I’ll end up in Unity or something but right now, I’m NOT going to worry about gimbel locking just yet.

Right now, I use Excel to sketch out most of my ideas, or I’ll throw together a video using whatever I can find to do it or worst, I’ll try to draw. Ugh.

But what I’ve been missing is a sketchpad for simple animating line drawing that respects basic physics.

There’s a chasm between understanding and doing and I want to bridge this old foe.

So, for example, I was in church for Mother’s Day (been a few years) his morning and I was entertaining myself thinking about modeling the movements of various players.

Folks coming in from parking lot, through ushers acting as doors who then close actual doors and join a group inside, the various directions they face and the group up front usually faces them, the directions they turn at different parts of the service.

and I thought, “I want to quickly model that. But with what?”

Then it hit me: Magnets in the floor.

Depending upon where you stand, you will face a particular direction and do a particular thing given a certain concentration and or time passing.

So if you stand in the Usher spot, you do Usher motions which are distinct from group coming in, distinct from pastor and others.

So, will Processing allow that? I dunno. But I know I could get pretty far with vectors alone.
