Detailed Description

A class used to setup CornerSmoothFlag in CPatch.

NB: it works with a compiled CZone (ie added in a landscape, and got with landscape->getZone()). NB: it changes values directly in CPatch (which it should not be permitted...), but don't except see the changes in realtime.

the doit method.

this Zone and his 8 neighbors should be added into a landscape. this method call setCornerSmoothFlag() on all CPatch of the zone. All corner smooth are set to false but if:

  • the corner is a vertex on a bind 1/X OR the vertex has exaclty 4 patch around him. AND
  • All edges sharing this corner must be smoothed getSmoothFlag()==true. AND
  • All edges sharing this corner must be "SameEdgeOrder", ie the patchs sharing this edge must have same number of tiles along this edge.
This is important for noise computing, and lighting.
