+Star-geometry-3d
+================
The purpose of this library is to help create clean and decorated 3D
geometries. These geometries are suitable to be partitioned into
-enclosures using the star-enclosures library. It also provides
+enclosures using the star-enclosures-3d library. It also provides
mechanisms to construct triangle-related app data, detect
inconsistencies and dump the resulting geometry in various formats (OBJ,
VTK, C code chunks).
