Ok, hi I managed to get the Geometry and put it into a new Shape3D and
displayed it. I was very happy, when I could see your surface in mine
"GIS3DView"!
Unfortunately it is not in the right place.
I am displaying my other objects directly at their world coordinates.
For example the surface I developed with VisAD has the following vertices:
Messstelle mit ID 246539
y Rechtswert: 3549415
x Hochwert: 5496636
z Gelaendehoehe [m]: 179.35
Messstelle mit ID 286032
Rechtswert: 3547115
Hochwert: 5502025
Gelaendehoehe [m]: 171.06
Messstelle mit ID 306035
Rechtswert: 3546710
Hochwert: 5501795
Gelaendehoehe [m]: 171.0
Messstelle mit ID 20096031
Rechtswert: 3548125
Hochwert: 5498345
Gelaendehoehe [m]: 175.0
Messstelle mit ID 20176037
Rechtswert: 3547638
Hochwert: 5500060
Gelaendehoehe [m]: 174.0
Messstelle mit ID 20186032
Rechtswert: 3547949
Hochwert: 5499551
Gelaendehoehe [m]: 174.9
Messstelle mit ID 20196038
Rechtswert: 3546885
Hochwert: 5497250
Gelaendehoehe [m]: 189.2
but the GeometryArray from the Shape3D has the following Point3d-Objects:
Wich kind of Transformations are done by the VisAD Delaunay Triangulation?
Is it possible to get rid of them? Or how do I get my original coordinates
back?
Again, many thanks for your patient help, Desiree
