Here is my entry, using Pillow script from late 2011.

Another possible approach is to make a loft through some sections like this where the curved corners are gradually expanding on each layer:






The loft initially has an open top, I then turned on surface control points and collapsed the circle edge down to a single point using the edit frame (there is a "flat" snap that you can use for that) and then also flattened that squished down point to be in the same plane as the next inside row of points, having a collapsed point be in the same plane as the next level of points will make a smooth looking tip instead of a sharp point.

For this kind of a thing you want the sections to only gradually change in shape, if you have too big of a change from one section to the next it can make things bumpy. Using Loft style = loose can help reduce bumpyness.

I know that the desired shape here is quite specific: a more rounded domed center that morphs to more pinched corners.

With NURBS construction there are so many ways to achieve surface configurations, each having their own character.

Though, the examples I give are more rounded on the corners, some of the possible construction methods may hold just as viable:

""""""""""there is no transition of the corner to a round edge"""""""""

But that statment along with:

"""""""""With no visible edges/seams""""""""""""

Does not exist..... Hence, all the examples you see have rounded corners, or "concave before convex" at the corner points.

ok then please tell me what kind of geometry the buttons on the rendering show ?!

cheers


t.

the pillow script it was :-)


thanks!!!!

They show hard edges where the transition is... I thought you wanted to "fix" that...

Looks like you got what you wanted from Bemfarmers script.

different approach:

BTW, I thought it was pretty obvious BEFORE I started working it out. Took about a dozen tries.

Nice!

Okay, now try it on the odd-shaped corner rounded buttons. ;-)

looks like it works on rounded corners too:

Is this different approach a network? You show your result but I am not clear how you did it.

Here ya go. Puffy buttons in 18 easy steps. Its actually very easy

Very nicely done. Thanks for sharing your method.

I bow to your genius! Great solution!

I'm going to give that a try, :)
