Welcome to Xj3D codebase.  

This are notes for the 9 Sept 2002 dev release of Xj3D. 

Major changes since M5:
-----------------------
	Complete rewrite of all of the event model evaluation code. It is now 
  	    fully specification compliant. It is also much more efficient and 
		generally renderer-independent. The only time it dips into renderer
		dependent code is for navigation and view-dependent actions. 
		(ie sensors) No garbage generated and only updates all objects once
		per frame rather than after every eventIn recieved. 

	Initial implementation for a mobile-capable browser/renderer

    Full runtime support for an in-memory VRML scene with no rendered output. 
	   Not all works yet, no navigation or any sensors, just basics. 

	Vector math library following OpenGL conventions

	ProximitySensors now support position_changed and orientation_changed

	VisibilitySensors more accurate about when they are detected

	Protos and Externprotos coming and going from the scene graph work correctly
	  for the inclusion of sensors and bindables.

    Hex encoding of integer values works for all SF/MFInt32 fields.

	MultiTexturing. Modified version of the Blaxxun proposal but more VRML-like.

	OpenGL renderer supports IFS and more efficient vector maths. Viewpoints movable
	    and bindable. Multi-pass rendering available for handling output devices like
	    Elumens Dome & VisionStations. 

	LOD is back functional again.

Known Issues:
-------------
    browser
	    Viewing files with the Java3D-based renderers are causing stuttering 
	        problems when dragging the mouse. This appears to be some issue 
	        between Java3D and Swing as debugging shows that the J3D behaviours
	        are still executing internally, but are not blitting the pixels to 
	        screen. There's nothing we can do about it.
        Reloading a file with multiple inlines using the same URL but not DEFed 
            will cause a multi_parent exception. Switching to a 
            SimpleLoadManager instead of a MemCacheLoadManager will resolve.
        GeoVRML and UMEL local resolution not supported in pre-compiled code,
            you need to specify the local installation path in DIYBrowser.java
            and recompile.
           
    DOMViewer
        Does not support scripts or protos in XML documents.
        Since it sets every field of a node it can uncover bugs that DIYBrowser
        won't.
        
    loader
        Works as advertised

    SAI_DOM_Demo
        Nonfunctional as of M3 release.
