The GNU Triangulated Surface Library

File Release Notes and Changelog

Release Name: 0.6.0

Notes:
In this version, all the input functions are using a new structure
(GtsFile) which fixes the problem of reporting syntax errors when
reading input files. A detailed message describing the location (line,
column) and the type of syntax error can now be easily set. All the
read() methods of the library classes now use this mechanism which
gives far clearer error reporting.

This comes at a cost however and a number of input functions
(gts_surface_read() etc...) have changed interface. Using the examples/
it should be easy to port your code though.

Other significant changes include:

*  New gts_surface_refine() syntax: allows for more generic cost functions.

*  New gtscheck executable: checks for topologically incorrect
   surfaces using in particular the new function
   gts_surface_is_self_intersecting().

*  src/: gts.h, partition.c: Bisection algorithms now takes an extra
   "imbalance" argument which allows some control over the weight
   balancing of the partition.

*  src/cdt.c: Checks for degenerate triangles when looking for root
   of the search (thanks to Mashuda Glencross for reporting this
   problem).

*  tools/gtstemplate: for generation of a template used to create new
   object classes.

Plus a large number of small (and not so small) bug fixes (thanks to
all the peole who reported bugs, their names are listed in the THANKS
file).
