About

Geodesica is an OpenGL(r) cross platform Geodesic modelling program that is designed to make advanced geodesic construction fun and easy to understand. The program is quite sophisticated and can generate dual space frames in Quad-Edge mode. Struts and angles can be measured interactively with labels identifying the respective components.

Geodesica is programmed in C++ using a modified version of the Wild Magic 3 graphics engine; the UI was built with the FLTK toolkit. Geodesica runs on Linux™ and MS™Windows.
