I went out tonight to three art openings around town and I was totally jazzed from seeing art. So I have come home and tried to do something before I go to sleep. This is my first sketch that is a continuation of the day before.
I was looking at things and thinking about in-between. I have made a simple patch that takes yesterday’s patch but adds a cloud of random points and I can do linear interpolation between the two. It is crude right now but there are some very interesting intermediate states between objects that arrive. I have also properly implemented the Dan Shiffman sugar from his space junk sketch so I get some more variation from frame to frame.
Again, OPENGL so code will follow the image, now animated.
