set OPENVRML_DATADIR=C:\openvrml-0.18.6\data 
set OPENVRML_NODE_PATH=C:\openvrml-0.18.6\src\node
set OPENVRML_SCRIPT_PATH=C:\openvrml-0.18.6\models\rotation_toy.wrl

 

It still crashes on me.

I would like to use OpenVRML to open and parse VRML files.  Does this require a node/scripting engine?

 

If I ever distribute my own stand-alone VRML reader/viewer based on the OpenVRML libraries,
can I do this minimalistically, without any node/scripting setup?

 

I was hoping openvrml.dll was the only file I needed to distribute.
