[Opensim-dev] [realXtend] Re: 3Di Viewer "Rei" goes open source (BSD licensed in-browser viewer)

I'm partial to the .X format myself:

- Yes, it originated proprietarily, but it's fully documented & standardised. The original source no longer uses it.
- It's binary and easy to parse. (low filesizes)
- Features a lot of things that would be good for VWs (mesh animations, skeletons, etc)
- There's importers and exporters for just about every 3D package. (probably better supported than COLLADA)
