int D.move( ) animates the contents of D until a button is
pressed and returns the pressed mouse button. If
the movement is stopped or no mouse button is
pressed, NO BUTTON will be returned, else the
number of the pressed mouse button will be returned
(see also Definition and the get mouse operation
of the window data type).
int D.get mouse( ) does the same as move.
int D.read mouse( ) calls move as long as move returns NO BUTTON .
Else the movement is stopped, and the number of
the pressed mouse button is returned.
void D.set position(node v, double x, double y, double z)
sets the position of node v in the visualized graph
D to (x, y, z).

Get- and set-operations
The following operations can be used to get and set the parameters of D.
operations return the previous value of the parameter.
bool D.get x rotation( ) returns true, if D has rotation about the x-axis
enabled, false otherwise.
bool D.get y rotation( ) returns true, if D has rotation about the y-axis
enabled, false otherwise.
bool D.set x rotation(bool b) enables (disables) rotation about the x-axis.
bool D.set y rotation(bool b) enables (disables) rotation about the y-axis.
bool D.get elim( ) returns the hidden line elimination flag.
bool D.set elim(bool b) sets the hidden line elimination flag to b. If b is
true, hidden lines will be eliminated, if b is false,
hidden lines will be shown.
bool D.get solid( ) returns the solid flag of D.
bool D.set solid(bool b) sets the solid flag of D to b. If b is true and the
current graph of D is a planar map, its faces will
be painted in different grey scales, otherwise the
faces will be painted white.
bool D.get draw edges( ) return true, if edges will be drawn, false otherwise.
bool D.set draw edges(bool b) enables (disables) the redraw of the edges of D.
string D.get message( ) returns the message that will be displayed on top
of the drawing area of the window.
