Hi Tobias,
The 3D extension does not work with 1.1 sources, you must develop against
1.10 sources if you want to get it work. So.. you say that your task is to
implement the gvSIG 3D extension in Eclipse RCP, do you mean to implement or
to port gvSIG 3D? Do you need the whole gvSIG or only the 3D visualization
framework?
Let us know your advances if you are allowed, it is a very interesting
development for us!
Cheers.
