I think there would be interest in 3D boards, but there are two issues:

(a) 3D rendering code
(b) the code for moving chequers around etc.

In order to make (b) work the programmer of (a) should provide formulae
for determining chequer positions, point positions, cube positions, dice
positions, so we can determine what to do if we get a single click at
position (427px,325px).


I think most of the code present in gnubg in gtkboard.c can be reused.
We just need to write new functions that determine what is "under" a
given pixel position.

I definitely think it's a good idea!

BTW, is there are port of OpenGL to windows?
