Create a server for 3D worlds similar to opensim with python and postgres, the goal ist to have a small and fast implemetation. Also to build a viewer working in a browser.
VisSim is a visual simulator for semi-stationary objects written in C++. The viewer can move around in three dimensional space to view the object from different directions and distances. VisSim uses OpenGL/GLUT and it runs in client-server mode.
