Well, the wood will be thinnest in the corners and thickest at the centre of each piece. Assuming you want at least 1/2" everywhere, you need to:
Take the difference between the inradius (radius of the sphere tangent to the faces at their centres) and the out- or exradius (of the sphere tanget to ...

Stella uses OpenGL (the Open Graphics Library) for rendering. AFAIK this is just like the real world in that it needs a light source or everything looks black. The 3D rotation, perspective and stuff is also handled by OpenGL, so decoupling the colour from the rest of the software might be a problem ...

You have your X, Y and Z axes. How do you go beyond these?
Mathematically it is really easy, you just add a W axis at right angles to all the others. When you project a 3-D object onto the X-Y plane (say a computer screen), you just forget the Z dimension. Similarly, to project a 4-D object onto ...

Rob, doesn't Stella offer svg vector output for nets and perspectives? These can be displayed directly in any modern web browser, or printed off, and crucially at any scale without loss of detail. They are even cross-platform.
Sorry I can't check my own copy, I no longer run Windows and am not yet ...

Yes, there are many such polyhedra, known as deltahedra. See for example the Wikipedia
Deltahedron article.
