Re: [www-vrml] some questions about X3D

[Reed Hedges <reed@interreality.org>]

I've been slowly working on a VRML "server" for VOS/A3DL (the Abstract 3D Layer
for the Virtual Object System; See http://interreality.org).  In the next few
months I hope to focus on it a bit more.  

A3DL specifies a scenegraph of VOS objects (Vobjects) that is different from X3D
and VRML's scenegraph in many regards but not disastrously so.  The objects in
the A3DL graph have types and send and recieve messages over the network to
reflect or change state, and otherwise communicate. This is not based on any
Web/HTTP stuff at all. 

The VRML Server reads in a VRML file, creates the equivalent A3DL object structure, 
and then you can talk to it using VOS (e.g. with the A3DL rendering client, "terangreal"). 
Currently not all VRML nodes are supported; after I finish adding those missing
nodes, the next step is to get routes and scripts working.

If anyone wants X3D support in that server, I can put that on my TODO list.
(Even better, you can help me write it in the server, or create a nice X3D
library in C++ I can use).

Let me know if you want to help or are otherwise interested in this project.
