Hi, thanks for your help, I found a Shap3D there, but I have problems
detaching it:
public void displayChanged(DisplayEvent e) {
if (e.getId() == DisplayEvent.TRANSFORM_DONE) {
System.out.println("displaychanged");
BranchGroup branchGroup = renderer.getBranch();
branchGroup.detach();
Enumeration enum = branchGroup.getAllChildren();
System.out.println(branchGroup);
while(enum.hasMoreElements()) {
Object o;
o = enum.nextElement();
if (o instanceof BranchGroup) {
System.out.println((BranchGroup) o);
}
if (o instanceof Shape3D) {
System.out.println((Shape3D) o);
Shape3D shape3d = (Shape3D) o;
// GIS3DView machen und fuellen
GIS3DView gis3dView = new GIS3DView(true);
Layer3D layer3d = new Layer3D();
layer3d.addShape(shape3d);
gis3dView.addLayer(layer3d);
GisTermService s = GisTerm.lookupService("GisTerm");
JTabbedPane p = gisTerm.getTabbedPane();
p.add("VisAD",gis3dView);
p.setSelectedComponent(gis3dView);
}
}
}
I get the following exception:
