I put the program and its source-code in its own folder. It requires windows to run , i'm using Windows 7 64 bit on my computer But FreeBasic is a 32bit...
It started as a Sphere made by D.J.Peters on the Freebasic forum under "General / Squares" It made a sphere out of triangles in OpenGL.  I played with it...
Buckyballs Astronomers have discovered the solid form of tiny carbon spheres in deep space inside a vast cloud of particles locked in orbit around two distant...
Hi folks, Geometric modeling is a great passion of mine. I've been experimenting with techniques to build polyhedra for many years now and though it all I've...
I've always had an interest in spherical geometry. I once wrote a program for an HP HP-97 printing programmable calculator that calculated iteratively (miunute...
It sounds like your prism's are :  You've got patterns on the outside of the sphere, and they shrink as you delve into the sphere, but remains the same...
Thank you. The prisms are of 2 types: regular pentagonal & irregular hexagonal in cross-section. There are 32 in all - 12 pentagonal & 20 hexagonal, each type...
Perhaps a good question to ask regarding this problem is what spherical geometry programs might be available that might be able to tackle this sort of thing. I...
I'm not an expert, although I have used Mathematica, which seems like a great program to me. However, here's my humble view on your problem. You said the...
Hi Caroling I'll have to give your suggestion some thought. The method you suggests (using the sides & angles of known regular pentagonal prisms to determine...
I've taken another look at the truncated icosahedron & I had picked up a mistaken impression along the way that the pentagons were regular and that the...
I forogt i had a soccerball program on my computer, a guy named Dodicat on the FreeBasic forum had posted it a year or so ago. He writes unusually complex...
I've taken a look at the truncated rhombic triacontahedron & you might have picked up the impression that the pentagons were regular and that the hexagons were...
Hi & thanks for the reference. It makes the following statements which I'm not following: The truncated rhombic triacontahedron is a convex polyhedron...
