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: http://gts.sourceforge.net 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.
