Showroom

SHOWROOM - Revolves a 3D plot showroom-style.

This function was especially designed to provide for those moments when you just created a
stunning 3D plot, and feel the need to sit back and admire the result for a moment. The
animation mimicks a cliché revolving automobile showroom, hence the name.

Syntax:
SHOWROOM Revolves the current plot at the default speed for one revolution
SHOWROOM(N) Revolves N times
SHOWROOM(N, V) Revolves N times with angular speed V (deg / sec)

- By default one revolution (N = 1) is performed at 30 degrees per second (V = 30).
- When no figure is active at the moment, a standard peaks plot is generated.
- A button press or click on the figure terminates the animation prematurely.
- For counterclockwise movement, enter a negative value for V.
- For 2D views and views with elevations close to 90 degrees this function happens to
cause a psychedelic flip-effect.
