OpenGL is kinda neat. I toyed very briefly with animations, trying to learn it the summer of 2016 after I met some guys who worked at Imaginex. I wanted to experiment with it to make cool animations like you might see in a fractal animation YouTube video. I didn’t get very far, but I did do enough to figure out a general strategy for building complex geometric animations.
Start with a simple shape (in my case, a square) and apply a function to it. Now you have a new pattern! Apply another function to this pattern, you get a totally new pattern. Keep applying patterns until you get something totally crazy and complex, all built out of simple building blocks.
0: start with a boring square
P = sq
1: make that square empty
P = empty(sq)
2: now make it pulsate
P = pulsate(empty(sq))
3: a grid of squares (0’)
P = grid(sq)
4: a grid of empty squares (3+1)
P = grid(empty(sq))
5: a grid of pulsating empty squares (2+3) or (4x(2))
P = grid(pulsate(empty(sq)))
6: a zooming grid of pulsating empty squares (5’)
P = zoom(grid(pulsate(empty(sq))))
I got some weird behavior here, with the green lines disappearing.
This is something totally different… Spin!
Now, to make the whole grid rotate!
