geom.edge.start.poly
Syntax
- p = geom.edge.start.poly(e)
Get the first polygon attached to edge e. This is used to iterate through all polygons attached to an edge using the
geom.edge.start.index
,geom.poly.next.poly
andgeom.poly.next.index
functions.Returns: p - polygon pointer Arguments: e - edge pointer
Usage Example
The following example illustrates how geom.edge.start.poly
can be used to iterate through all polygons connected to an edge.
global test20 = geom.edge.id(geom.poly.edge(pnt,1))
global test21 = geom.node.id(geom.poly.node(pnt,2))
global test22 = geom.poly.normal(pnt)
global test23 = geom.poly.pos(pnt)
global test24 = geom.poly.area(pnt)
; 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)
