Re: [Nel] How to use NLMISC::CPolygon::toConvexPolygons function

Yes. As the method doc says:

 

* Convert a concave polygon into a list of convex polygons using a 2d projection.

* The polygon mustn't overlap itself in the XY plane of the basis passed in parameter.

* The polygon must be direct in the XY plane of the basis passed in parameter. (Counter clock wise)

 

Just give an identity matrix for "basis" and all should be fine

Hi

Can we correctly use NLMISC::CPolygon::toConvexPolygons function with 2D concave polygons,by making z-axis = 0 for every vertex,or is there any other way to convert a 2D concave polygon into a list of convex polygons.
