Ruby angle_between issue

More elegant solution: # Counter-clockwise angle from vector2 to vector1, as seen from normal. def angle_in_plane(vector1, vector2, normal = Z_AXIS) Math.atan2((vector2 * vector1) % normal, vector1 % vector2) end def edge_angle(edge) angle = angle_in_plane(edge.faces[0].normal, edge.faces[1].normal, edge.line[1]) # Assuming mesh is oriented, i.e. edge is reversed in exactly one out of the two # faces. If not, the return value depends the order the faces are presented in. edge.revers…
