Detailed Description

Generates a three dimensional view of the network and connections using OpenGL. Stores a data representation of all the neurons and connections. Parameters for this display are set using the Network Viewer Properties widget. Some of the methods are adapted from gltools, provided in the OpenGL Superbible, Third Edition.
