### gts-0.5.1 README file

    General Information
    ===================

    This is the GTS library. GTS stands for the GNU Triangulated
    Surface Library. It includes a number of useful functions to deal with
    triangulated surfaces including, but not limited to, multi-resolution
    models, Delaunay and Constrained Delaunay triangulations, set operations on
    surfaces (intersection, union etc ...), bounding-boxes trees for efficient
    collision and intersection detection, triangle strips generation for fast
    rendering.

    The official web site is:

    Copying
    =======

    The GTS library is distributed under the terms of the Library General
    Public License which is compliant with the guidelines of the Open
    Source and Free Software Fundations. See the file COPYING for details.

    The robust geometric predicates code (src/predicates.c) was written
    and placed in the public domain by Jonathan R. Shewchuk. The original
    version of the code can be found at

    http://www.cs.cmu.edu/~quake/robust.html

    Installation
    ============

    Unix users:

    ./configure
    make
    make install

    See the file 'INSTALL' for generic configure instructions.

    Windows users:
    If you have Microsoft C try:

    cd src
    nmake -f makefile.msc install

    Using GTS
    =========

    From version 0.5.0 you can use the `gts-config' script in order to
    obtain the compile flags and link flags necessary to use the GTS
    library (à la Glib).

    - To compile add `gts-config --cflags` to your compiler flags.
    - To link add `gts-config --libs` to your linker flags.

    When developping code using GTS you probably want to enable control
    over casting operations between objects of the GTS object
    hierarchy. This can be done easily by defining GTS_CHECK_CASTS either
    in the CFLAGS environement variable (CFLAGS=-DGTS_CHECK_CASTS) or on
    the command-line of your compiler.

    This will slow down your code but will warn you when you try to
    perform illegal casts between GtsObjects.

    You can also to do that using the `--check' option of gts-config,
    i.e. by adding `gts-config --cflags --check' to your compiler flags.
