From the PickCanvas-doc:
<snip>
PickCanvas pickCanvas = new PickCanvas(canvas, scene);
pickCanvas.setMode(PickTool.GEOMETRY_INTERSECT_INFO);
pickCanvas.setTolerance(4.0f);
Then for each mouse event:
pickCanvas.setShapeLocation(mouseEvent);
PickResult[] results = pickCanvas.pickAll();
<snap>
PickIntersection PICKINTER = results[0].getIntersection(0) ;
from the PickIntersection-doc:
<snap>
Point3d getClosestVertexCoordinates()
Get coordinates of closest vertex (local)
Point3d getClosestVertexCoordinatesVW()
Get coordinates of closest vertex (world)
<snip>
You will have to check for length-0 or null PickResult-arrays and you have to
set some capabilities on the shapes and geometrie-arrays.
have fun.
