virtual bool DtIntersectRecordPassThroughLayer::chordIntersect ( const DtChord &  chord, DtVrfChordIntersectionRecord &  record, DtIntersectionRecord::DtIntersectionType  irtFlag = DtIntersectionRecord::INT_ALL_DATA, bool *  dataAvailable = 0, bool  overrideBlockingAssert = false, int  flags = 0  ) const

virtual

Returns topmost intersection of chord with terrain in record.

Parameters

Input
chord	the chord to test
irtFlag	specifies what intersection data should be filled in for the record.
Output
record	the results of the intersection
dataAvailable	Please see "Synchronous and asynchronous calls with paged terrains" in DtTerrainInterface for information on how to specify that this function be blocking or non-blocking. If this parameter is specified and the required terrain data is not yet paged in, this call will return immediately and dataAvailable will be set to false.
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.
flags	optional flags to pass into the intersector. The flags are implementation dependent

Implements DtTerrainImplementation.
