gl_trisetcolorlookup(3)	      Svgalib User Manual      gl_trisetcolorlookup(3)

NAME
       gl_trisetcolorlookup, gl_trigetcolorlookup - manages a color lookup ta-
       ble for shadowing

SYNOPSIS
       #include	<triangle.h>

       void gl_trisetcolorlookup(int i,	long color);
       long gl_trigetcolorlookup(int i);

DESCRIPTION
       gl_trisetcolorlookup sets the color of an index i in the	table used  in
       more than 256 color modes to interpolate	tables.

       Note  that  it is your responsibility to	set all	the intermediate color
       values.

       You can use this	function to create the index table, but	 remember  not
       to let i	go over	4096.

       gl_trigetcolorlookup retrieves a	previously set value from the table.

       Beware,	these  functions are not a direct part of the svgalib library.
       Instead their source is part of svgalib and can be found	in the threeD-
       kit/  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.

       In  case	 of  any such problem, simply get an svgalib distribution from
       the net.	Yo don't need to install it. Just make in the threeDkit/  sub-
       directory. As of	this writing, svgalib-1.2.12.tar.gz is the latest ver-
       sion  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 mirrored by a site close to you.

       The functions are defined in the	tri.o and triangl.o  files  (or	 their
       resp. sources) which you	must link to your program.
