Alright alright... I know it's silly but... what method do you use to make a sphere out of all Quads? -- I don't like the ball command as it gives triangles at the ends that do not deform right durring bump displacement or even subdivision. I think there is an All Quad ball that I have on a CD somewhere... am I best off just importing that when that is what I need? -- There has to be a relatively easy way to make it yourself. :)

One way is to make a cube then Metaform (shift-d) to taste :)

Yea I thought of that.... but would I be assured that the sphere is perfectly round? --- I may just find that sphere on the CD... to be perfectly honest... I think it's on Spline God's World Wide Tour CD. -- So I don't think I could post it here because of copy issues.

A box and Metaform + Spherize two or three times in succession?

Hey Minus,

This may work for you. Towards the end you'll want to use a reference sphere to shape this out, but it will give you a sphere made entirely of quads.

I'm impressed by your clever use of simple deformers, Steve! I took a minute to try and solve this myself, but wasn't succesfull. Really neat solution.

Ahh ... interesting. With that method I'm sure I could get it round enough for any of my purposes. -- Thanks!

@ minus: Happy to help! I hope it works out for you. :)

@ evenflcw: Thanks! :) I read in a book recently that 3-sided patches are really just 4-sided patches with two points occupying the same space. That sparked the idea that a quad could look like a triangle and still be a quad, which is sort of what minus was looking for. It might not be the most elegant solution, but it's worth a try. :)

Cheers!
