label &  quadI,
faceList triFaces,
faceList quadFaces 
) const

Split into triangles and quads.

Results in triFaces (starting at triI) and quadFaces (starting at quadI). Returns number of new faces created.

◆ compare()

int compare ( const face a,
const face b 
)
static

Compare faces.

Returns
  • 0: different
  • +1: identical
  • -1: same face, but different orientation
