Triangulate with beautify caused a bug when there were existing edges
could make the bmesh-operator return an invalid face-map.
Now the beauty is calculated on the 2d-tri's resulting from polyfill,
its simpler and faster.
- could crash if triangulate attempted to create an existing face.
- tagging edges to rotate was unreliable, don't do this anymore.
now check if edge is in the array passed to the beauty function.
Quads: Beauty, Fixed, Fixed Alternate, Shortest Diagonal
Ngons: Beauty, Scanfill
* Shortest Diagonal is the default method in the modifier (popular
elsewhere), but beauty is the default in Ctrl+T).
* Remove the need for output slot and beauty operator to be called
after Clt+T
Patch with collaborations and reviewed by Campbell Barton
The ear loop method is potentially too slow (OˆN).
We are not using the 'beauty' option at the moment.
I'll incorporate that next.
(and later specific methods for quad splitting)
Patch done in collaboration (and reviewed by) with Campbell Barton.
