Animating great circles

Introduction

This is an animation I did in 2004 which illustrates the intersection of great circles on a sphere. This particular dome was inspired by R. Buckminster Fuller's Bamboo Domes, an authority on dome construction. There is quite some documentation involved regarding techniques and mathematical equations needed for this animation.

I used the openGL library which is applicable to all operating systems. The language used is C++.

OpenGL is very well supported on the net, and all necessary documentation is readily available.
