Detailed Description

Environnement used to symmetrise zones.

This class build symmetry specific informations needed to know how transform tiles when a zone is symmetrise.

There is two states for a tile : Regular or Goofy. If the tile is regular, it doesn't need specific transformation when the zone is symmetrise. If the tile is goofy, the tile must be rotate by 180° more to be correct.

Member Function Documentation

bool NL3D::CZoneSymmetrisation::build (  const std::vector< CPatchInfo > &    patchInfo,
float    snapCell,
float    weldThreshold,
const CTileBank &    bank,
CError &    errorDesc,
const NLMISC::CMatrix &    toOriginalSpace
) 
 

Build symmetry informations.

Parameters:
zone  is the zone to build symmetry informations
snapCell  is the unit size of the zones
weldThreshold  is the threshold used to check vertex over snaped positions
errorDesc  is a structure used to return errors
toOriginalSpace  is the matrix used to transform back a vertex in its original position before symmetry / rotation
Returns:
false if the patch topology is invalid for this operations

)  [private]
 

Propagate tile state information for a given tile.

Parameters:
i  is the patch number in the zone that contain the tile to propagate
u  is the tile u coordinate in the patch
v  is the tile v coordinate in the patch
patchInfo  is a vector of patch information
bank  is the tile bank used by the landscape
forceRegular  must be true to force the first propagated tile to Regular if Nothing
Returns:
false if the patch topology is invalid for this operations true if succesful
