NOTE:	this is a quick guide to using TkSM.  I wish I had the time to create
	a tutorial (or at least a man page) for TkSM, but I didn't, and that
	is a low priority item right now.  If you have questions that you
	don't see answers for in here, please email me and I will do my best
	to respond as quickly as possible.

NOTE2:	A reasonable level of familiarity with basic 3D graphics concepts
	such as view volume, projection transformations, surface and vertex
	normals, material properties, and hidden surface removal is assumed.
	It would also help if you have access to "Computer Graphics: Principles
	and Practice" and "OpenGL Programming Guide", since I generally follow
	the terminology of the these two books in naming parameters.

Using TkSM is a two-step process.  You first create a cell and populate
the cell with 3D models.  Then you attach one or more viewports to the cell.
The viewports are 'windows' into the world (cell) occupied by the models,
You can have multiple viewports positioned at different locations in the
same cell to look at the objects from different perspectives.  

Please see the files:

  cell		for information about cells and models
  viewport	for information creating and using viewports
  texture	for information about creating and using textures
  vrml		for information about TkSM's VRML support
