[JAVA3D] using GeometryInfo for drawing surfaces with holes ?

[firas]

Hello !
I am trying to draw a 3D surface which could contain holes.

I found it feasable by using GeometryInfo ... But it seems to me that

GeometryInfo add a line from the last point to the first one then when

holes exist. The image could be deformed ...? Is there any idea ?

Another question, what is the best manner to build an interface (with menus

and icons) for a JAVA3D output ...?



Thanks for any help
