Detailed Description

Represents an area query which can be used to extract triangles from DtTerrainInterface.

The box points are in local but the box is always projected against the local topo at the center point of the box.

Member Function Documentation

virtual DtPoint DtTerrainProcessPolygonsBox::northeast ( bool  inLocal = true ) const

virtual

Corner point accessors.

If inlocal is true then the points will be passed back in the local coordinate system. If inLocal is false then the points will be transformed into a local topo coordinate system centered at the center of the box.

virtual

virtual void DtTerrainProcessPolygonsBox::setNewNW ( const DtPoint &  nw )

virtual

Corner points of box in local coordinate system.

virtual void DtTerrainProcessPolygonsBox::setNewSE ( const DtPoint &  se )

virtual

virtual double DtTerrainProcessPolygonsBox::minAltitude ( ) const

virtual

Min/Max altitude of triangles generated.

These values will be used regardless of the altitude of the points that define the box This is generally used to increase performance since finding all the triangles above and below a certain area can be very slow if you don't need them all. Defaults to -100000 to 100000
