scene graph viewer
mum8dad
Could anyone point me to a tool that visualizes a VRML file's scene graph?
In order to understand vrml and computer graphics in general, scene graphs
seem really important, so I'd like to see a graph representing one of my
simple worlds.
I got the Java 3D Scene Graph Editor (included with the Java 3D Fly
Through), but try as I might I can't get it running. I really want one for
vrml anyway.
Thanx for any help,
Dave.

This can be done with cosmoworlds ("outline editor"), white_dune
("Scene Tree"), glview etc...

( most are -- as you might expect -- Java ):
Viewing VRML Scene Graphs
-------------------------
| Picking of VRML objects with your mouse is demonstrated
| in a new book, Java 3D Programming, by Daniel Selman ....
|
| The source code is avaible for free.
|
| This new book uses the old, reliable
| Sun VRML Loaders for Java3d.
|
| The program reads a 3d scene as a simple VRML
| text file, and displays the Java3d Scene Graph
| ( which is interactive, you can expand and collapse
| the branches of the scenegraph and examine the
| contents of the nodes ), it renders the 3d scene,
| and when you click on an object it tells you what
| you clicked on.

White Dune VRML Editor / Scene Graph Viewer
-------------------------------------------
| White_dune is a low level VRML97 tool for
| Unix/Linux and M$Windows.
|
| It can read VRML97 files, display and let
| the user change the scenegraph/fields.
| Unlike most highlevel tools, it uses a light
| model based on the VRML97 standard.
|
| White_dune is not complete yet, especially in
| the 3D preview window. But even if you do not
| see the node/field in 3D, you can graphically
| change the values.

Sun's Java3d Fly Thru can read and render VRML
with their old, reliable VRML Loaders for Java3d,
I've used it, both the old version 1.0 & the newer
Netbeans version.
What problem did you have ?
What worked and what didn't work for you ?
I've found Sun's code to be very reliable
and it works reliably for me, it just has
to be set up properly.
I've used it on Windows & Linux, and have
almost entirely stopped using Windows entierly ;^))

Does this mean you can read a random .java file and extract the
java3D calls and change the scenegraph ? What is done with the
rest (non java3D) part of the .java file ?

using the Sun VRML Loaders but haven't used
it very much: it's new, under development and
some of the features are listed as "alpha quality",
others as yet unimplemented.
The Scene Graphs are taversalable through
standard recursive calls down the branches
(when set to be readable) and it operates
on the Scene Graphs and does not parse the
".java" files at all.
The MJB Editor may be more usefull to most
at this point ( both repeated below ).
Though the Sun / Netbeans FlyThru & Scene Editor
do have some interesting XML functions for
specifying the preferances & etc. and it lets
you move around and set some of the viewing
parameters and configurations so you can do
things like to "move to see the entire scene"
and find out what the ViewPoint position is.
The Source code is free & available so you can
see how any part, or all of it is done, and
you can improve on it, if you are so inclined.

So what is a "java3D scene graph" ?
Not (as the name let think) the structure of
graphic objects build as API-calls in a .java
file but a file with somehow stored 3D objects ?
A reenvented VRML97, OpenInventor fileformat,
Performer .pf? fileformat etc. ?

Spazz3d seems to do more for less at the
standard price and has an avid group entusiastic
users, and it also supports seamless
H-Anim Avatars by helping you create or
convert them ( example & info below ):
| Spazz3D has easy-to-use working views and
| the essential drag-and-drop scenegraph window
| where you can reparent nodes with ease.
| The tool bars are dockable so you can customize
| the layout of your workspace. The OpenGL based
| browser simulator does a good job of testing
| your work and the de-bugger is helpful for tracking
| down what events trigger what.

Yes, but at $150 it's more expensive and
appears to do less than Spazz3d:

With Java3d you get free tools for creating VRML
and viewing VRML scene graphs ( with these and other
programs ) and you can render interactive VRML
animations in a browser with the Sun VRML Loaders,
or you can do it out of the browser and read & write
to and from local files, or fetch files from the web.
