I almost hate to draw attention to this but just in case it ever matters...
For various reasons, I ended up writing some IVE readers in Java.
Mostly because I had some .ive files that no version of OSG I had
available would load correctly. And partly because this is the sort of
thing that feeds an odd manic part of my brain.
At any rate, the stuff is implemented to allow code configurable
profiles because I was pretty sure I was going to have to hack a
non-standard version. The result of which is something that is almost
like documentation... in code:
http://meta-jb.cvs.sourceforge.net/meta-jb/sandbox/src/java/org/progeeks/osg/io/StandardIveConfiguration.java?revision=1.11&view=markup
Each supported object type has an individual object profile with field
types added (with an optional version designator).
I never finished it so there are some objects that aren't defined yet
but I got it to the point that it could load all of my own IVE files and
I was able to determine more about what was wrong with my bad ones.
There have also been some changes in the IVE format that are harder to
configure this way (byte ordering changes, etc.)... one day I may even
get back to it.
Not sure it's at all useful, but it does centrally describe (in a way)
the IVE format... with a little translation. Other than that, it's
probably only useful to me. :)

Thanks once again for the incredibly fast response. Up to now I've been
using the OsgDotNet wrappers, so writing a Custom Visitor class means
maintaining and updating the wrappers as well. At least, if I understand
the solution correctly. I will of course make every effort to leverage
the native loader.

Thanks Robert, grinding through the learning curve now. Getting to the
vertices was easy (getVertexArray). Was looking for something similar
for image/textures.
It's straight forward, just look at the NodeVisitor examples I
mentioned.
Is there any documentation on the IVE format? A spec file?
No there is no spec file, it is not meant to be read in a non native
way like an interchanges format such Collada.
Given you have a perfectly serviceable loader it'd be madness to try
and read it by hand, please just use my suggestion.
Robert.
