BIT-QUAD creation support: a few basic operations to work with bit-quads simplices (quads defined by faux edges over a tri mesh backbone)

[ basic operations: ]

bool IsDoublet(const FaceType& f, int wedge) void RemoveDoublet(FaceType &f, int wedge, MeshType& m)

• identifies and removed "Doublets" (pair of quads sharing two consecutive edges)

bool IsSinglet(const FaceType& f, int wedge) void RemoveSinglet(FaceType &f, int wedge, MeshType& m)

void FlipDiag(FaceType &f)

• rotates the faux edge of a quad (quad only change internally)

bool RotateEdge(FaceType& f, int w0a);

• rotate a quad edge (clockwise or counterclockwise, specified via template)

bool RotateVertex(FaceType &f, int w0)

• rotate around a quad vertex ("wind-mill" operation)

void CollapseDiag(FaceType &f, ... p , MeshType& m)

• collapses a quad on its diagonal.
• p identifies the pos of collapsed point (as either the parametric pos on the diagonal, or a fresh coordtype)

[ helper functions: ]

ScalarType quadQuality( ... );

• returns the quality for a given quad
• (should be made into a template parameter for methods using it)
• currently measures how squared each angle is

int FauxIndex(const FaceType* f);

• returns index of the only faux edge of a quad (otherwise, assert)

int CountBitPolygonInternalValency(const FaceType& f, int wedge)

• returns valency of vertex in terms of polygons (quads, tris...)
