Warning: currently the picking Utilities are not working with GeometryInfo
structure in which the Geometry Type is indexed (e.g. TRIANGLE_FAN_ARRAY,
TRIANGLE_STRIP_ARRAY, etc.).
Try to use others simple structures.
I hope this is useful for you.

Hi,
I managed to get the Java3D 1.2 Pick funktionaliy to work, but it is still
not working with Polygons I create with the help of GeometryInfo-Objects.
I get the following capability set exception:
javax.media.j3d.CapabilityNotSetException: Shape3D: no capability to allow
inter
sect

javax.media.j3d.BehaviorScheduler.doWork(BehaviorScheduler.java:167)

I tried to set the capabilites with the following:
ginfo.setCoordinates(coordsccw);
ginfo.setStripCounts(stripCounts);
Triangulator tr = new Triangulator();
tr.triangulate(ginfo);
NormalGenerator ng = new NormalGenerator();
ng.generateNormals(ginfo);
Stripifier st = new Stripifier();
st.stripify(ginfo);
// Set Appearance
Appearance app = createAppearance();
PolygonAttributes polyAppear = new PolygonAttributes();
polyAppear.setCullFace(PolygonAttributes.CULL_NONE);
app.setPolygonAttributes(polyAppear);
-> ginfo.getGeometryArray().setCapability(Geometry.ALLOW_INTERSECT);
// Create Shape3D
Shape3D shape = new Shape3D();
shape.setAppearance(app);
shape.setGeometry(ginfo.getGeometryArray());
shape.setCapability(Shape3D.ALLOW_APPEARANCE_READ);
shape.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);
-> shape.setCapability(Geometry.ALLOW_INTERSECT);
sf3d.addChild(shape);
But it is not working. So what now?
I really appreciate your help, thanks Desiree
