The following PickCanvas code works OK for me:
PickCanvas pickCanvas = new PickCanvas(canvas, root);
pickCanvas.setMode(PickTool.GEOMETRY_INTERSECT_INFO);
pickCanvas.setTolerance(1.0f);
...
pickCanvas.setShapeLocation(x, y);
PickResult results = pickCanvas.pickClosest();
if ( results != null )
{
PickIntersection info = results.getIntersection(0);
intersectionPoint = new Point3f(info.getPointCoordinates());
}
Hope you can get some help from this.
