Before building, make sure that you have the OpenGL development libraries installed.
make
./vince
When running this in the program’s window try hitting space a few times and see what happens!
The vince.alt.c code of the submission will run on SGI IRIX and
also has the recursive CPP
macro (which sneaked in accidentally) removed.
To compile this alternate version:
make alt
Use vince.alt
as you would vince
above.
Try it just like vince
as above.
This beauteous entry makes use of visual {}
s and whitespace to instruct the
OpenGL development libraries to create beauteous
visuals. Even hitting the space bar while the program runs produces a “spacey”
effect! :-)
NOTE: when hitting space bar make sure that the program window is in focus!
Challenge: Try modifying the texture to something of your own design.
The executable needs to read in its own source code in order to run. As long as the source is in the same directory as the executable it should be able to find it…
The program requires the OpenGL library.
The program abuses severely the whitespace and { } ;
exceptions in the
file size limits.
OpenGL. It works (slowly) with Mesa.
16bpp graphics capability (but might work at other depths)
The original source needs to be in the same directory as the executable,
and the source’s name should be the same as the executable but with .c
on the
end.
I was annoyed after the last IOCCC because I slaved away on a clever text based game only to find all of the game entries used X11. X11 isn’t standard C!
So to one up them, I decided to use OpenGL. It’s standard, and most Unix-like systems these days have either accelerated graphics or else software rendering.
It was a challenge getting the source code below the 2k limit. OpenGL has way
too many ‘GRATUITOUSLY_LONG_CONSTANTS
’ and ‘glLongStudlyFunctionNames();
’.
Therefore, much of the obfuscation comes secondary to just reducing the code size to fit under the limit while still having some semblance of a demo.
There are some interesting abuses scattered about.
Try hitting the space bar when the program is running.
Try modifying the texture to your own custom design…
Many thanks to John Clemens for testing this on various machines for me.
