Fixed regular expression so that they match better and more efficiently (without leading whitespace). None of my old VRML models could be loaded using the previous versions of the regexes.
Fixed overwriting the scene instead of adding to it in VRML loader example. This preserves the lighting and the controls, so that the Box can be spinned and is lit.
first, rather primitive import of IndexedFacedSet
Now loading an Indexed faceset with the correct normals applied and shapes with more then 3 angles split up into triangles
- IndexedFaceSet parsing
- Improvements when it comes ot USE statements.
- Transforms and scale get applied to the wrong nodes, because the parsing is unaware of in which node it currently is.
- Fixed rotation by replacing the way the Quaternion is set
- Fixed loading indexed facesets, something went wrong when trimming the strings
- Loading the geometry of an indexed faceset is now (in basic form) complete
- Simpler calculation (by calling a method on the geometry) of face normals
- Double sided material is friendly towards crappy  IndexedFaceSets
- New model (house) in example
