Re: [Visualpython-users] 3d surface plot animation

>From the documentation section "Delete an object":

To hide a Visual object just make it invisible: ball.visible = False.
This does not delete the object from computer memory, and you can make
it visible again later.

If however you later re-use the name ball, for example by creating a
new object and naming it ball, Python will be free to release the
memory used by the object formerly named ball (assuming no other names
currently refer to that object). If the object is visible when you
re-use the name ball, the original object will not be deleted from
computer memory, and it will remain visible in the window.

After you make an object named ball invisible, you can delete it
immediately with del ball.
