Sorry John it didn't work.It gives the same result (NULL).
As my last choice I will post some of the code. Maybe you can figure out
somethig wrong. Here it is:
///////////////////////////////////////////////////////
//This checks downwards .Parameter "point" is the center of the ball
///////////////////////////////////////////////////////
public void CheckPocketed(Point3f point){
Point3d end = new Point3d(0 ,-5 , 0 );
Point3d start = new Point3d(point);
SceneGraphPath[] result = null;
start.add( end);
PickSegment pickSegment= new PickSegment(start, end);
result = branch.pickAll(pickSegment);
if (result == null) { System.out.println("Ball Falling!"); }
else System.out.println("Ball NOT Falling!");
}
///////////////////////////////////////////////////////
////This is another class that creates the table and the lamp. I set picking
capability bits too.
///////////////////////////////////////////////////////
public class Table extends TransformGroup{
TransformGroup TableTG;
TransformGroup LampTG;
public Table() {
this.setCapability(Node.ENABLE_PICK_REPORTING);
String filename = "3DModel\\pooltable.3DS";
Scene theScene = null;
Scene accessory = null;
///////////////////////
//Creating the Table///
Loader3DS loader = new Loader3DS();
TableTG = new TransformGroup();
try{
theScene = loader.load(filename);
TableTG.addChild(theScene.getSceneGroup());
TableTG.setCapability(Node.ENABLE_PICK_REPORTING);
TableTG.setPickable(true);
}
catch ( IOException e )
{
System.err.println( "** Exception: " + e.getMessage() );
e.printStackTrace( System.err );
}
Transform3D trans3D = new Transform3D();
trans3D.setTranslation(new Vector3f(0.0f,-0.8f,0.0f));
trans3D.setScale(0.7);
TableTG.setTransform(trans3D);
addChild(TableTG);
//Etc. The file creates other elements that are add to transformgroups
other than TableTG.
THANK YOU

PickSegment ,I am picking from the center of the sphere (transformed center)
downwards (I add a point below the center to it), but I am getting null.

check if it is on the table or pocketed. However ,after picking
scenegraphpath is null, even though the ball is above the table. I am using
Picksegment and calling branchgroup.pickAny().
