Each mesh has material information. PhysicalComponents contains user interface architecture for Teddy. Most of it is work in progress. You should know about the Projection class. The Area class is baseclass for all user interface components, looking at it wont hurt.
Physics contains a very very simple physics simulation code.
Scenes contains scene and camera related stuff of Teddy. SysSupport contains directory scanning and timer code. Teddy in the root source directory is the main application. The UI class contains all highlevel testing environment setup and runtime operations. The simulation thread maintains system time.
