Hi,
I am trying to use the PickTool object to allow the user of a 3D
environment to choose any part of a loaded scene graph (using a
pointer-like device), and subsequently translate/rotate the entire scene
graph using this pointer device.
However, although the user is able to pick an object (a Shape3D object),
when I try to use the getSceneGraphPath() function of PickResult, the
resulting SceneGraphPath object that is returned contains only the
terminal leaf (the Shape3D object) and the root object - all nodes
inbetween (which I have manually verified do exist) are not part of the
returned pathway.
The following is a snippet of code used to retrieve the picked object and
resultant scene graph path:
-------------------------------------------------------
//create a PickTool for the current Locale and make it a cylinder
PickTool pickTool = new PickTool(getLocale());
pickTool.setShapeCylinderRay(wandOrigin, wandDirection, 10.0);
PickResult result = pickTool.pickClosest();
//make sure the user picks a valid object
if (result != null)
{
SceneGraphPath path = result.getSceneGraphPath();
System.out.println("Number of nodes in path: " + path.nodeCount());
// ...
}
---------------------------------------------
This problem persists no matter what kind of scene graphs I load into
Java3D.
Any suggestions on why the SceneGraphPath returned has no intermediate
nodes? Thanks!
Ted
