we are not using Galileo yet, so the six methods you mentioned in your
original post are not implemented in GEF3D. I suggest you either
implement them yourself or wait until we do it. Either way, there are
some methods in the Graphics class that we do not support properly yet.
I have just committed a new version of LWJGLGraphics that has support
for some of those methods (mostly setters that will be ignored now).
Those methods that still throw an exception are now documented in the
class javadoc.
I suggest you update to the latest revision and have a look. I hope
this helps get GEF3D to run for you. If you have any further problems,
let us know.
