887.0. "Atari Boing! Demo" by MEIS::ZIMMERMAN (Angry goose! Angry, angry goose!) Tue Nov 10 1987 12:33

    I saw an impressive ST demo at Lechmere's in Nashua yesterday.  It
    had a couple of red and white checkered spheres and a couple of
    mirrored spheres tumbling around each other over a plane covered with
    Atari logos that slid off toward the horizon.  It was nothing that
    you couldn't do on an Amiga - just a ray-traced animation loop - but
    a customer looking at an Amiga running Boing! and an Atari running
    this thing might conclude that the Atari was a much more
    sophisticated machine.

    That is a fairly old demo called 'Shiny Bubbles', and it is indeed
    very impressive, despite the limited color pallette.  The images
    were ray traced, then stored consecutively in RAM.  The original
    Amiga Boing! demo was done the hard way, through pixel moving. 
    I don't think the ST could duplicate the original Amiga Boing! ball
    without the blit chip, at least not as fast as the Amiga, since
    the Amiga blitter supposedly can draw twice as fast as the 68000
    can.
    
    The Atari is a very capable animation machine, if one uses page
    flipping of pre-recorded frames.  I believe it can hit 30 frames
    per second or more.  The Amiga has been clocked at 60 frames
    per second.  The Apple ][GS is limited to about 5 frames per second.

    I remember reading somewhere that Atari did duplicate the Boing!
    ball demo, and ran it at a rate faster than the Amiga version.
    Of course, it didn't have the booming thud sound, or have
    any cpu left over to multitask with (the amiga ball demo isn't
    running at max speed).  But for the demo wars, it did make their
    demo look better.
    
    Hopefully the disks from the Badge Killer Demo contest will be
    available from Fred Fish or even C-A soon (rumor on usenet that
    C-A might want to ship them to each dealer).
