Thank you Bo. Good catch. The current version of Xj3D has fixed this
bug. You can either jump into the current version of CVS or wait a few
days(likely April 20th) and we will be tagging a new release of the
project as stable. I spent a fair bit of time pouring over the
IndexedFaceSet code so I'm hoping I've cleaned up any remaining bugs.
Other bugs of note that have been fixed as well include:
Problems with handling ccw flag - resulted in weird texturing
Incorrect handling of non-uniform scales - caused incorrect translations
I'd also encourage future bug reports to be placed on the source list.
