       threed - The svgalib 3d demo


       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  environment  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 animation 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 system 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 limited 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   at   /pub/Linux/libs/graphics   and   at
       /pub/linux/sources/libs which will most probably be mirrored by a site close to you.

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