I was thinking to write a program to generate an eye. I don't draw and I don't model - I program.

I like doing procedurally generated geometry and procedurally generated UV coordinates. It means I can change a few parameters and alter the density, polygon arrangement, etc without having to move a bunch of vertices by hand or with tools I don't understand. Of course, this technique is totally useless for something as irregular as a human. But the eye is basically a few curves revolved around a center line.

I prefer using refraction on the cornea rather than transparency, because when viewed from the side, a transparent surface does not "lift" the iris into view with transparency. But Poser deems a refractive surface to be a shadow caster. That's a problem. An eye that was actually made in two parts would allow me to disable shadows on the cornea. Which is why I was thinking of generating eyes procedurally, as I could not in a million years make the edges line up perfectly smooth between cornea and sclera.

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)
