Hi Bill and all others,
I did manage to include the with VisAD created Delaunay Shape3D Object in
my application.
/**
* Triangulation of given set of points with delaunay. This method
* throws an event, when 3D-Objects are ready. See displayChanged.
*/
public void makeSurface() {
//System.out.println("Hallo Delaunay!");
RealType x = RealType.getRealType("x");
RealType y = RealType.getRealType("y");
RealType height = RealType.getRealType("height");
try {
RealTupleType xy = new RealTupleType(x, y);
FunctionType terrain_type = new FunctionType(xy, height);
Irregular2DSet set = new Irregular2DSet(xy,new float[][]
{eastValues,northValues});
FlatField terrain = new FlatField(terrain_type, set);
terrain.setSamples(new float[][] {heightValues});
display = new DisplayImplJ3D("display1");
ScalarMap hoxmap = new ScalarMap(x, Display.XAxis);
ScalarMap reymap = new ScalarMap(y, Display.YAxis);
ScalarMap heightmap = new ScalarMap(height, Display.ZAxis);
display.addMap(hoxmap);
display.addMap(reymap);
display.addMap(heightmap);
hoxmap.setRange(-1.0, 1.0);
reymap.setRange(-1.0, 1.0);
heightmap.setRange(-1.0, 1.0);
DataReferenceImpl data_ref = new
DataReferenceImpl("data_ref");
data_ref.setData( terrain );
renderer = new DefaultRendererJ3D();
display.addReferences(renderer,data_ref);
display.addDisplayListener(listener);
}
catch (VisADException ve) {
System.out.println("VisAd TupleType Exception");
}
catch (RemoteException re) {
System.out.println("RemoteExcpetion");
}
//System.out.println("Delaunay ende!");
}
Is it possible with visad to get a shap3d of a part of this triangulation?
Say, I do have coordinates of a point and want to clip the parts of the
object, which are more far away, than 10m, or something similar?
Thanks for your help in advance
Desiree
