By the way, the sphere ain't the only way to get round shiny things.

Here's a demo of something I did for a friend recently. He needed LOTS of bubbles.

I made a shader that generates them on a one-sided square. This scene has two of them, each with 10,000 bubbles. That's 20,000 bubbles altogether. You can't see them all because I cropped the shot.

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)
