I tried 0.80 downloaded from the website and the Xith3D SVN trunk with XIN from the website. The XIN on sourceforge doesn't look much different from the one on the website. Unless there's more than one version of XIN and I was looking at the wrong one. The actual code in XIN has at least one syntax error, there's a closing parenthesis missing from one of the EmptyScene examples.
The XIN examples don't compile with 0.8.0. You should use the new 0.9.0-beta1 or SVN Trunk. There is only one XIN version on the Website, which should always be the PDF export of the current SVN OO-version. The only different versions out there are versions downloaded earlier

.
Could you maybe give me a hint, on which page / chapter the syntax error is? I will fix it then.
I tried using Xith in SWT with the old code from old tuts extracted from my old projects and it seems to work, the new wrappers give me a "no renderpipeline defined" error. Maybe my code isn't complete enough to cause the error, but it shouldn't be too difficult to get Xith running in SWT.
Sorry, the SWT renderer is not yet complete. It's just the enum constants that are already there, to make people familiar with them. Amos Wenger will complete it soon. He said, it's not too complicated.
