Detailed Description

This file contains functions for answering common Topological and geometric queries about a mesh, such as, "What is the angle between these two faces?" or, "How many faces are incident upon this vertex?" Tool authors should use the functions in this file instead of inspecting the mesh structure directly.

Returns the verts of an edge as used in a face if used in a face at all, otherwise just assign as used in the edge.

Useful to get a deterministic winding order when calling BM_face_create_ngon() on an arbitrary array of verts, though be sure to pick an edge which has a face.

Note
This is in fact quite a simple check, mainly include this function so the intent is more obvious. We know these 2 verts will always make up the loops edge

This is for use in cases where creating a face is possible but would result in many overlapping faces.

An example of how this is used: when 2 triangles are selected that share an edge, pressing F-key would make a new overlapping quad (without a check like this)

earr and varr can be in any order, however they must form a closed loop.
