Detailed Description

This terrain implementation is a polygonal terrain representation.

Polygons can have a soiltype defined and an associated color. It is in the GDB format which holds both the polygons and any associated vector features.

virtual bool DtGdbTerrainImplementation::loadTerrain ( const makArchives::DtGenericTerrainRecord &  rec, MAKVRinTerra::DtFeatureLoader &  featureLoader, const TerrainSettings &  settings = TerrainSettings()  )

virtual

Loads a terrain given the terrain record and a key/value pair of settings.

These settings are interpreted (or not) by the implementation

Implements DtTerrainImplementation.

virtual bool DtGdbTerrainImplementation::chordIntersect ( const DtChord &  chord, DtChordIntersectionRecord &  record, DtIntersectionRecord::DtIntersectionType  irtFlag = DtIntersectionRecord::INT_ALL_DATA, bool *  dataAvailable = 0, bool  overrideBlockingAssert = false  ) const

virtual

Returns topmost intersection of chord with terrain in record.

irtFlag specifies what intersection data should be filled in for the record.

Implements DtTerrainImplementation.

virtual bool DtGdbTerrainImplementation::allIntersectsAlongChord ( const DtChord &  chord, DtChordIntersectRecordList &  intList, DtIntersectionRecord::DtIntersectionType  irtFlag = DtIntersectionRecord::INT_ALL_DATA, bool *  dataAvailable = 0, bool  overrideBlockingAssert = false  ) const

virtual

Returns all intersections of chord with terrain.

intList is the list of each intersection record. irtFlag specifies what intersection data should be filled in for the record.

Implements DtTerrainImplementation.

virtual

Returns

A DtTerrainCapabilites structure that describes the capabilities of the currently loaded terrain.
