Neighbor data
Any given face may have 0 or more neighbors along a given edge. In the illustration below, the face ABC has two
neighbors on the edge opposite vertex A, one neighbor on the edge opposite vertex B and no neighbors on the edge
opposite vertex C.
A manifold mesh may have three or more faces meeting at one edge
You can obtain information about the neighboring faces of a given face using the neighbor property. You can use the
following Lingo code to find out which face is the neighbor to face seven, opposite vertex 13. First, find where vertex
13 appears in the list of vertices for face 7.
put member("3D").model(1).meshDeform.mesh[1].face[7]
-- [13, 14, 11]
Now you know that 13 is vertex one in the face list for face seven, you can ask for the neighbor of vertex one:
put member("3D").model(1).meshDeform.mesh[1].face[7].neighbor[1]
-- [[1, 8, 2, 1]]
