Detailed Description

A landscape patch.

QuadPatch layout (same notations as 3ds Max SDK).

A---> ad ---- da <---D | | | | v v ab ia id dc

| | | |

ba ib ic cd ^ ^ | | | | B---> bc ---- cb <---C

NB: Patch 1x1 or 1xX are illegal: lot of problem: rectangular geomoprh, Son0 and Son1 must be setup as tile at beginning ...

NB: Edges number are:

  • 0: AB.
  • 1: BC.
  • 2: CD.
  • 3: DA.
