Display of scalar 3-D datasets through static and animated slices (the latter can be saved as movies), contour slices, and iso-surfaces.

This is a simplified version of the 3-D volume viewer "V3D" written by Robert Barsch and available from the Matlab File Exchange, File ID 2255.

The main differences are:

Most of the menu buttons have been replaced by those in Matlab's standard menu bar.

The GUI's are in English and have been adapted to R14.

The function has the standard help section with examples.

There is a "Need help?" menu button.

The volume to be viewed must be the first argument of the function (no input from a file).

The axis annotation (labels) of the volume plotted can be specified.

The z-axis can be up or down (for geophysics).

The axis aspect ratio can be "equal" or "normal" (in Matlab parlance).

A number of minor modifications (such as make handles of GUI's and main window "invisible", "reuse" GUI windows, add/change defaults, request confirmation before closing of the main window, delete all open figures when the main window is closed) have been made to fit the way I prefer a GUI like this one to work.

Disabled button (Faecher) the intended functionality of which I could not guess and for which the call-back function did not exist. 

Changed some of the defaults (length of pause during animation, initial slice).

Added some error trapping.
