Liquid Brain using Managed DirectX 9.0


Liquid Brain is a Managed DirectX animated example of hexagonally close packed spheres. In Hexagonally close packed formation, spheres are efficiently packed together so that each sphere is surrounded by 12 other spheres. For more information about close packed structures, visit: 

The spheres in the program are represented by the "Particle" class. Each particle is programmed to have up to 12 neighbor particles. The particles are programmed to prefer to be located close to each of its neighbors according to the close packing formation. When any particle is moved to a new location, it will attempt to re-establish the close packing and therefore will move toward it's neighbors. Likewise, the neighbors of that particle will also move to re-establish the close packed formation. The results is a very fluid and organic motion.
