geom.poly.next.index

Syntax

ir = geom.poly.next.index(p,i)

Get the index of the next edge of a polygon. This can be used to iterate through all polygons connected to an edge using the geom.poly.next.poly function.

Returns:

Returns:	ir - edge index
Arguments:	p - polygon pointer i - edge index

ir - edge index

Arguments:

p - polygon pointer

i - edge index

Get local index ir of an edge within the next polygon attached to this edge (note: the same edge has local index i within the source polygon p). This can be used to iterate through all polygons connected to an edge using the geom.poly.next.poly function.

Returns:

Returns:	ir - edge index
Arguments:	p - source polygon pointer i - edge index

ir - edge index

Arguments:

p - source polygon pointer

i - edge index

Usage Example

The following example illustrates how geom.poly.next.index can be used to iterate through all polygons connected to an edge.

    ; Test edge to poly loop
    global test25 = 0
    local edge_pnt = geom.edge.find(setpnt,1)
    local poly_pnt = geom.edge.start.poly(edge_pnt)
    local edge_ind = geom.edge.start.index(edge_pnt)
    loop while poly_pnt # null
        test25 = test25 + 1
        local next_pnt = geom.poly.next.poly(poly_pnt,edge_ind)
        edge_ind = geom.poly.next.index(poly_pnt,edge_ind)
        poly_pnt = next_pnt
    end_loop
