3D object viewer/converter?


I've been searching for centuries...well...actually just once every few weeks for the last year or so...for something remotely resembling Right Hemisphere's Deep Exploration, with little results. I've had 3dto3d installed for a long time, but the help files make no sense to me. I generally don't have too much trouble with commandline applications, but when it comes to working with graphics a GUI is really the only logical approach.
I've also found a program called Convex3D, which is as close to ideal as I've found so far, but have had much difficulty installing it (numerous errors that seem to have nothing to do with dependencies or environment).
Does anyone have suggestions about another GUI alternative? Specifically I'm looking for something which will read Lightwave objects (this is essential, since most of my 3D work is in LWO format).
Ideally, though not essential, it would use OpenGL to display formats including 3DS and BLEND, and be able to export some format readable by Blender.

The Blender plugins I've found which read LWO and 3DS don't work for me...there seems to be issues with Blender and the various versions of Python (seems each specific version of Blender requires a specific version of Python, or some stupid thing like that)...so I'm left searching for other ways to get my Lightwave objects into Blender.

So basically I'm searching for one of three possible solutions:
1) a GUI tool which will read/convert LWO and 3DS
2) some documentation for 3dto3d that doesn't read like source code
3) a way to get my Python scripts to work in Blender (blender version: 2.32, Python version: 2.3)

Thanks for any help.

3dto3d works well enough - command line win/lin etc
For more complex things use blender- it has a number of import export scripts. that come with it

Blender 2.x will NOT support python 2.3 use python 2.2.x instead.

Blender works fine with python 2.3 if you compile it from source.

D'OH!

That's one of the few applications which has failed to compile for me....guess I'll give it another go...
Thanks.

I have a text file here that you might find useful if you're having trouble compiling.

Thank you...this file was very helpful. After making modifications to the appropriate files, and installing Mozilla includes (20mb - yick!), Blender successfully compiled with Python2.3, YAY!
I have no idea if the Python version was the cause of the trouble now. Running some scripts would cause it to crash with an error about missing modules. After rebuilding, the crashes stopped, but instead I got an error about the same missing modules. It turns out that I had somehow added a comma to my $PYTHONPATH...removing it allowed the scripts to find what they needed.
Thanks again...another mystery solved.

edit: I was wondering about one of the changes from that text file, though...is there a particular reason to _not_ use OpenAL? I'm concerned about this if I ever get to the point where I'm using audio in Blender.

The OpenAL support is only used by the game engine and it's somewhat broken atm, but I assume it will be fixed for the next release.

Ok...I assumed they've been having trouble with the game engine, as it's not been mentioned much since Blender was raised from the dead.
I'm just happy that I don't have to bury my old Lightwave files now =o)
