Assign to DtRwBoundingVolume. Assigns value only.

virtual const char* DtAttachedTerrain::readerWriterType ( ) const

virtual

Used to supply a string type that this reader writer type is.

This can be used in place of dynamic-casting. Also used by the opd editor to determine which type of control to create

virtual

virtual bool DtAttachedTerrain::closestIntersection ( const DtVector &  curPosition, DtVector &  intersection, bool  ignoreWater, bool *  dataAvailable = 0, bool  overrideBlockingAssert = false  ) const

virtual

Returns true if a there is a terrain intersection at the given local position.

The algorithm checks for intersections along a chord in the direction of gravity at that location (from halfHeightOfChord above to halfHeightOfChord below localPosition). If ignoreWaterSurface is true, advances through list of intersection returned until first DtSurface that is not a water surface is found.

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

virtual

Computes the list of all intersections of a chord (in Database Coordinates) with the attached terrain database.

Parameters

Input
chord	the chord to test
irtFlag	specifies which data should be calculated and returned for each intersection point

Note

that passing an irtFlag value of INT_EXISTS will probably never return more than one intersection.

Parameters

Output
intList	the result of the terrain intersection
dataAvailable	Please see Synchronous and Asynchronous Calls with Paged Terrains for information on how to specify that this function be blocking or non-blocking. If the data is not yet paged in, dataAvailable will be set to false and intList will not reflect any terrain intersections
overrideBlockingAssert	when set to true this parameter will prevent an assertion from being thrown when the terrain implementation has myAssertOnBlockingTerrainCalls set to true. This should only be done when the call is being made from outside the main simulation thread and a blocking call would not cause a a problem.

Returns

result of the terrain intersection or data availability

Return values

true	if the chord intersects the terrain
false	if dataAvailable was specified and returns true, then the chord does not intersect the terrain. Otherwise false indicates that the data is not yet available.
