Menu Method
The method menu is filled by the active geometry and therefore depends on
its geometry type. Please note, that the active geometry is set in Inspector-Display, or by ctrl-tab mechanism, or
by ctrl-right mouse.
Here is a list of frequent geometry classes and their menus. Note, that
the menus are inherited by subclasses.
Menu Method for PointSets
Allows to apply several geometric and non-geometric operations on the
current object.
Info
These methods print debug information to the JavaView console window which
is opened by Ctrl-d or F3 or by invoking menu Window->Console
or via the popup-menu in the display.

re-calculated. Should never be necessary.

display to the JavaView debug console.
