Ok, I think I got it,
The VisAd Geometry is stored in a TriangleStripArray, in my Example I had
7 Points, which would build 6 Triangle with a complete of 18 Vertices as I
thought. I fact the GeometryArray has 20 Vertices (I forgot to change the
last two). But why do I need 20 Vertices to build a TriangleStripArray
with 6 Triangles?
Again, many thanks for your help, I really appreciated your fast and
professional answers, thank God there is a thing like the Interent and
e-mail.
