ARE FOUR GAITS,

LEAVES THE GROUND
ENTIRELY AT SOME

Computer graphics are
usually either RASTER
images or VECTOR images.
Raster images can be
thought of as an elec-
tronic sheet of paper --
anything you draw on the
paper can be displayed
later.  Vector images
can be thought of as the
dots in a connect-the-
-dots drawing.  The
computer can connect
the dots with line seg-
ments if desired.

In order to animate a
raster image, all one
needs to do is draw
the individual frames
that are needed for
the animation.  The
process is just like
making cartoons, ex-
cept you do not need
to redraw the whole
page (screen) if you
don't want to--and,
of course, you can
change, redraw, re-
color, etc. as often
as you like.

This cross-section view of an airplane
wing shows that the wing bulges at the
top near the front and then tapers to a
point at the back.  This shape causes
air to flow in a manner that creates
lower pressure on the top, which effec-
tively "pulls" the wing up.

When the airplane is moving very slowly,
as when taxiing or starting its takeoff
run, even pressure is exerted above and
below the wing and therefore it cannot
lift the airplane.  Here, greatly en-
larged air molecules are shown passing
over and under the wing.

The air passing over the wing travels
further and faster than the air which
passes under the wing.  As the airplane
picks up speed, this causes the pressure
on top to be lower than on the bottom.
The wing "pulls" in the direction of the
lower pressure, lifting the airplane.

It should be noted that the propeller or
jet engine serves merely to move the
wing (and the airplane) foward through
the air, but they do NOT provide the
lift.  The distinctive shape of the wing
--known as an AIRFOIL--is what causes
the airplane to fly.

This is a demonstration of the graphics
 capabilities of this program.  If you
  would like to see any portions of it
  again, you can get to the Airplane
 section at any time by pressing the
 letter "A"; the Horse section can be
   reached by pressing "H", and the
beginning of the demo can be reached by
 pressing "D".  Also, the "return" key
 will move you foward through the file,
and during the viewing of the four horse
  gaits, Pg Up and Pg Dn will move you
 back and forth through the animations.
 Press any key to start the demo over or
  to go to any part as just mentioned.
