Will the edge flips to improve degree collide with edge flips that make a mesh more Delaunay? ie. Will flipping edges to make a degree approach 6 cause the mesh to be less Delaunay or vice versa?
While performing remeshing over and over again, the "improving degree" algorithm above can fall into the trap of flipping an edge back and forth. Do we just keep extra state to detect and stop it?
How many iterations over the mesh is good in practice? Also, is it possible to have an infinite loop if you decide to go until you don't see any you can switch for a whole iteration cycle over the edges?
How exactly does flipping an edge increase the number of elements? When you flip an edge, the number of faces and edges seem to stay the same
For this algorithm when would you know when to stop? Would it be when avg degree is within some epsilon of 6?
Why edges flips and triangle rounds can bring the better quality? Also, can a face be bended even there is not an edge across it?
Since the average degree approaches 6 an the number of elements increases, is there ever a case when it would be beneficial to increase the number of mesh elements in order to improve the average degree?
When would be a good time to stop flipping?
