Ashish,
I have written a PickScreenObject class that allows you to pick Shape3D
object(s)
off the screen , and put them in an array. It is implemented as a Behavior.
.Right now it allows you to select any Shape3D NODE by clicking on it on the
screen.
But how to receive/use that Shape3D node in your main program is not done (I
guess
it is your job). One way could be to extend PickScreenObject to implement
PickingCallback and then retrieve the geometry inside your callback class's
method (for drawing lines between them etc).
I have included a sample program which uses this behavior also.(ColorTest.java)
Hope this will help you in figuring out your problem.
Regards,
Anand

Hello Anand!
Thanks very much for your continuing help and because
of it I have understood lot of things. But there is a
problem with the program. Shape3D myShape is null and
hence the if loop which states that:
if ( myShape != null ) is not executed.
I am getting the message "scenegraph path is null",
which you will get if myshape is null.
Please inform me why myshape is null. I am attaching
the program with this mail for your reference. Please
run the program and try to draw a line between two
solids, you will get messages in console window. I
hope you won't have to waste too much time over it.
Thanks for your continuing supoport.
Ashish
