Faster file reading. Interface for calling Triangle from another program. Triangle neighbor lists. Objects can be numbered from zero. Ability to suppress insertion of new points on the boundary, thus preserving compatibility with adjacent meshes.
Handles duplicate input points correctly.
Of special interest. Triangle's robust geometric predicates are available separately from the Robust Predicates page . If you use Triangle or Show Me , and especially if you use them to accomplish real work, I would like very much to hear from you. Also, let me know if you want me to put you on a list to receive email whenever a new version of Triangle, or another tool in the Archimedes chain, is available. No need to fear a full mailbox.
