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
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
In case of any such problem, simply get an svgalib distribution from the net. Yo
dont 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
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.
