I had almost no time to play today. But I did achieve an important milestone in my geometry toolkit.

There is a square path with rounded corners, expressed as a parametric function.

This path is then stretched in the vertical axis to form a square-spiral.

Following that path, I extrude an oscillating and evolving cross section.

This particular shape is pointless, but it assembles and demonstrates a number of important techniques that I will need later.

It contains 86400 polygons.

I know that the ZBrush guys have all this worked out already, but I'm enjoying figuring it out from first principles.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
