Function Documentation

◆ bm_extrude_copy_face_loop_attributes()

static void bm_extrude_copy_face_loop_attributes	(	BMesh *	bm,
		BMFace *	f )

static

Copy the loop pair from an adjacent face to both sides of this quad.

The face is assumed to be a quad, created by extruding. This function won't crash if its not but won't work right either. e_b is the new edge.

Note: The edge this face comes from needs to be from the first and second verts to the face. The caller must ensure this else we will copy from the wrong source.

When create an edge for an extruded face region check surrounding edge flags before creating a new edge.
