Scene-Tree

 

This project tries to display a global view of the data hierachy tree. This is useful for GRAPE novices which are not sure about the object buttons in the manag menu, and it allows to quick navigation in a complicated data hierarchy.

Scan the data hierarchy tree from its root. Print the result on stdout.

Pick in the tree window.

left mouse:

goto object, as if walked in the local view in the manag menu

middle mouse:

The project adds the display method "draw-scene-tree" as well, which allows to zoom and rotate or to print the tree; the user interface operates with send-methods found at class Root.
