-Project description
-
-Implementation of simple portable 3D graphics library.
--------------------------------------------------------------------------------
-Dependencies:
-
-Dojo Core, dojox.gfx.
--------------------------------------------------------------------------------
-Documentation
-
-Not ready yet.
--------------------------------------------------------------------------------
-Installation instructions
-
-Grab the following from the Dojo SVN Repository:
-http://svn.dojotoolkit.org/var/src/dojo/dojox/trunk/gfx3d.js
-http://svn.dojotoolkit.org/var/src/dojo/dojox/trunk/gfx3d/*
-
-Install into the following directory structure:
-/dojox/gfx3d/
-
-...which should be at the same level as your Dojo checkout.

They are rendered in arbitary order. In this case, BSP is the rescure.</p>
