[vtkusers] creating polygons from polylines and making holes in polygons (isolines related)

[sebastien MARAUX]

Hello,

I have a few questions :

0. I load some polylines from a file, describing isolines and
 "negative islands" isolines, I assume I can identify negative
 islands by putting a scalar for it ?

1. How to create solid polygons from polylines (ie isolines) ?

2. How to make holes in this polygons with other polygons
(negative island isolines)

Thank you in advance for your tips, tricks and advices.

Seb
