FANTASIA
              Author:  Tony Barker, Sydney, Australia


This demonstration has been written as an interactive demonstration
of the STe.  It represents a simple yet fun way to experiment with
mouse control and the artistic potential of the STe.

For the technically minded, we are introducing 32 colours on the screen
at any one time, most of the objects refresh at 15 frames per second with
some of the smaller objects refreshing at up to 50 frames per second.

The sound sample used in FANTASIA has been captured at 12517Hz as a
single channel mix.  If you are looking for a stereo mix, then refer to
BOINGSTE which we have also placed into the public domain.


TO OPERATE:

-       Double-click on FANTASIA.PRG to launch this demonstration.
        Yes!  FANTASIA may be launched in either low or medium resolution.

-       FANTASIA will begin in AUTO mode allowing you to observe each
        of the 3D objects that are an integral part of this demonstration.

-       Press the RETURN key to switch to any of the objects that are
        an integral part of FANTASIA.

-       The control panel at the base of your screen shows the position
        of each axis of the object on the screen (THETA, PHI, RHO), the
        DISTANCE is an arbitrary unit of measure from your viewing point,
        while the CONTROL slot indicates whether FANTASIA is in KEYBOARD, 
        AUTO or MOUSE control.

-       To begin to appreciate the power of FANTASIA, we suggest you
        select the MOUSE option (toggle the SPACEBAR until the word MOUSE
        appear in the control slot) and hold down the left mouse button.
        Immediately, the object on the screen will begin to move forward
        into your viewing plane.  Alternatively, by holding down the right
        mouse button, the object will recede from your viewing frame.

-       As a next step, move the mouse around the table in either 
        a circular or horizontal manner.  Observe how easy it is to 
        manipulate the object through each of the three axis.

-       Once you have mastered this step, press the "C" key on the 
        keyboard.  This toggles the screen clearing mode to an OFF
        position.  Again, use your mouse controls to manipulate the
        object . . . . and observe the results!  Experiment at will
        and discover how you can create your own fantastic shapes
        which seem to pulsate and swirl.

-       To restore the screen clearing mode, press the "C" key.


EXTRA HELP:

-       Press HELP and an illustrated picture will appear on the screen
        showing each of the controls.  Press any key to return to the
        control screen.

-       Press UNDO to restore your object to a zero status position.
        A useful step to restore the orientation of an object.

-       Press "Q" on the keyboard to return to the desktop.

-       The subtle nuances of FANTASIA are best realised with the
        keyboard mode selected.  Study the HELP screen to understand
        how you can control the rotational paths of your object from
        the numeric keypad.
 
-       Remember, pressing the RETURN key will toggle between the
        various objects that are part of FANTASIA. 

-       Be sure to connect your Atari STe to the loudest "ghetto blaster"
        you can place your hands on and pump up the volume.  Enjoy!
