This directory contains class diagrams that describe how the MeshVizXLM interfaces have been implemented and intergrated in this demo.
 
	- PillarGrid.jpg shows the design of the PillarGrid data structures. 
	  The 2 types of data storage PillarEGrid and PillarGridJIK are used according to the DemoSettings.h file.
	- PillarMesh.jpg shows the design of the MeshVizXLm interface implementation wrapping up the PillarGrid data structures.
	  The demo instantiates a CachedTopoPillarMesh class.
	- SubSampling.jpg shows how to use MeshVizXLM interfaces to create a subsampled pillargrid without duplicating the data.
	- Demo.jpb shows how to integrate the PillarGrid and MeshVizXLM into an OpenInventor scenegraph.
