Summary

0001203: portions of vrml models being dynamically culled out

Description

This is really a problem w/ the vrml importer,
but i've had little suvvess tracking down anyone still attached to that code, so.

With the VRML models at:
http://predictor.scripps.edu/scientific_update_gallery.php [^]

As one gets closer to the models,
various portions of it seem to be culled out of the scene,
as if by a visibility test,
even tho those portions are well within view.

Also picking is very dodgy.

The models are composed of several sub-objects,
but there appears to be no tricky transforms in the file.

Have loaded & re-written them with 3rd party software,
obtaining a differently-structured file but with the same results.

See attached screenshots.

(0001494 - 55 - 61 - 61 - 61 - 61 - 61) elenzil 05-16-05 21:38	actually i think this may be my fault. more to come...

(0001495 - 700 - 1012 - 1012 - 1012 - 1012 - 1012) elenzil 05-16-05 23:14	confirmed: this was introduced in my own version by me. it's frustrating tho - the cause was that i re-configured the behavior of #scale: so that instead of this: --- SomeClass scale: s multiply my own translation by s. actually scale myself. for all my children: child scale: s. --- it was like this: --- SomeClass scale: s actually scale myself. for all my children: multiply child's translation by s. child scale: s. --- this makes a lot more sense to me because with the previous way, if you scale an object, it translates ! however, this ran into complications with the boundSphere of TMeshes which i haven't been able to sort out.
