Delaunay triangulation in Lua.
Based on Delaunay triangulation library by Yonaba ([email protected]).
Deviations from original library:
- Triangulation function takes array instead of tuple;
- Use LuaJIT FFI if possible( turnable off ).
Using FFI increases performance roughly x2.
Using FFI reduces memory usage approx. on 40-50%. It's possible to futher decrese memory use by setting:
_G.DELAUNAY_FFI_TYPE = 'float'in this case memory usage drops on 60-70%. Note that you must set it before the library is loaded and shouldn't change it later.
