gl_trisetcolorlookup(3)       Svgalib User Manual      gl_trisetcolorlookup(3)

       gl_trisetcolorlookup, gl_trigetcolorlookup - manages a color lookup
       table for shadowing

       #include <triangle.h>

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

       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

       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
       threeDkit/ 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

       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/
       subdirectory. 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.

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