am trying to do something similar. This is the what i did not sure if it
would work for you or if this is how its supposed to be. i brokeup the vrml
file into several small vrml files one for each object.Then read the smaller
vrml files one at a time as a node and modified their individual properties
using their node paths. If anyone can tell me of a way where i can modify
the properties of multiple objects within the scene using a single vrml file
it would be great.

I have recently start using TGS Open Inventor for Windows NT but I have to
confess that I am facing some problems. I am involved in a medical project
aiming to deliver robotic therapy to patients that have suffered from
stroke. It has been decided that we will use a combination of virtual and
real tasks to deliver appiling activities to the user. This surely will
in patient's motivation and improve the recovery time. The first prototype
is intended to go to one hospital at the end of December for clinical
To start with, I have modelled a virtual room using 3D studio MAX and have
converted this scene into VRML 97 format. Somehow I have managed to read
VRML scene into Open Inventor, but my main problem now is on how to access
the VRML scene in order to perform actions such as, move objects from one
location to another, detect when a collison occured, etc. Despit the books
(The Inventor Mentor, The Inventor Toolmaker, and TGS Extesions User's
guide) I am still lost! I have been trying to find examples but couldn't.
I wonder if you could help my in this matter, if you have any documentation
(tutorials, examples, etc) which relates to the problem discribed. Anything
will help! It is extremely difficult for me at the moment and without
yet the abstraction behind computer graphics and the way Open Inventor
really works adds to my difficulty to solve the problem.
I will be very gratfull if you could help me in any way. I am looking
further to hearing from you.
