NAME
     threed - The svgalib 3d demo

SYNOPSIS
     3d

DESCRIPTION
     Well, the 3d demo...

     I, Michael, the current svgalib maintainer, do not have any source for it.

     Thus,  you  may experience weird problems with new svgalib versions and you
     need installed a.out libc and svgalib versions.  Also the demo is known  to
     be  buggy	in several aspects. Thus, do not panic if it appears not to work
     for you.

     If it works in a certain mode for you be happy and play around with it. For
     example, with recent svgalibs, 3d is unable to initialize the mouse if  not
     started directly in a linux console for unknown reasons.

     Otherwise: Don't worry at all.

   Here's the author's (Harm's) info about it:
     There's  also a 3d demo binary included in this directory. It has been in a
     similar state for several months now, but I'm planning  to  get  some  work
     done  (although  it probably won't be the amazing multi-player networked 3D
     lightsource-shaded real-time VGA virtual reality simulation). I'll  release
     the source code at some point (when it has some degree of flexibility). I'm
     sorry that there's no scene description file; it will come. So now you know
     you can do this kind of thing in Linux. And it's practically 100% C code.

     You  can set the graphics mode to be used with the SVGALIB_DEFAULT_MODE en-
     vironment variable (e.g. G640x480x256). All linear 256 color, 32K color and
     16M color modes are supported, with page flipping used if available. Planar
     256 color VGA modes also work. This should do 800x600 full screen 3D anima-
     tion at near 10 fps with a good system.  Request:	Please	report	if  page
     flipping  goes  wrong  on	a  particular  chipset (e.g. ET4000, Trident) in
     320x200x256. Also 32-bit pixel truecolor modes don't work	correctly,  this
     will be fixed.  The user interface is somewhat primitive at this point:

     - Use the mouse to rotate.
     - Left button accelerates, right decelerates.
     - Press <W> to move upwards, <S> to go down again.
     - Use <R> and <F> to control the zoom factor.
     - <q> or <Ctrl>-C exits.

     Note  that  the light source rotates quickly at an infinite distance.  This
     is not something that will easily occur naturally (as far as I know)...

     This demo is part of svgalib and can be found in the demos/ subdirectory of
     the original svgalib distribution. However, it is not installed in the sys-
     tem by default, s.t. it is unclear where you can find it  if  your  svgalib
     was installed by some linux distribution. Even then, when you have the demo
     on your system, you probably won't have the sources s.t. it is only of lim-
     ited use for you.

     In  case  of  any such problem, simply get an svgalib distribution from the
     net. You even don't need to install it. Just make in the demos/ subdirecty.
     As of this writing, svgalib-1.2.12.tar.gz is the latest version and can  be
     retrieved	by  ftp  from  sunsite.unc.edu	at  /pub/Linux/libs/graphics and
     tsx-11.mit.edu at /pub/linux/sources/libs which will most probably be  mir-
     rored by a site close to you.

BUGS
     Countless.
     In addition, source is still not available. Sorry, I just don't have it.
