Face

class m3sh.hds.Face(index)

Face base class.

In a halfedge based mesh representation a face is defined by the closed loop of halfedges starting at the halfedge attribute.

Parameters:

index (int) – Face index.

The vertices of a face can be visited in several ways. Using __len__() and __getitem__()

for i in range(len(f)):
    print(f[i])

is equivalent to using __iter__()

for v in f:
    print(v)

Note

The latter is much more efficient and preferred.
