Simple!?? NO! Those buttons look perfect. I have never yet figured out
how to model them. You've done the impossible. Can I have the code?

I love it, simple indeed and yet very stylish. Bravo!

Maybe.. I hate to dissapoint everyone, but the keys were modelled in
Rhino.

The trick is that the top surface of the key is not flat, but
cylindrically concave in the vertical direction. This makes a workd of
difference.

I'm sure the CSG expers out there can work out the filleting in POV.

Forget about CSG...do it with isosurfaces. ;-)
Actually, may not be too difficult...

Here's my attempt.

That's a great iso-key, Tor!

I tried to make a computer keyboard early in 1998 and never finished it.  No
characters on the keys or any
LEDs.  All CSG, it didn't look so good at the distance shown in the attached image.

Thank you Bob.

I wish that I could have patience to model things like these.

hmm, looked easy to me ;)
When hand-coding complex CSGs, it really, really, really, really helps to
know your math!

Well well... Yes, Tor Olav managed to make a real nice Iso-key...
Something I couldn't have done.. I tried some time ago..

Anyway, ISO's are slow, especially if one wants a whole key-board. And I
still would say, Simon de Vet's keys are the best... So, Simon, can we
talk you into sharing the Rhino-mesh with us? If you made a good
transfer it might be a small file.. :o)

I mean, now the key have been modelled, it is not necessary that I
struggle to model a similar one..

It's incredibly realistic! At the first glance I thought that it was a photo
(and I like the idea, too).

Very good
