Detailed Description

Description: DtSimSector is a readable/writable description of a sector of responsibility (center and size, both in radians), and some useful methods for using them.

Everything is projected onto the <x y>=""> plane (local), so the sector actually functions as a volume extending infinitely in both z directions.

assignment operator

virtual DtSimSector* DtSimSector::clone ( const DtString &  name, DtReaderWriterRegistry *  parentRegistry = 0  ) const

virtual

virtual int DtSimSector::operator== ( const DtSimSector &  rhs ) const

virtual

Returns 1 if sectors have the same size and same center; 0 otherwise.

virtual void DtSimSector::setSector ( DtReal  center, DtReal  size  )

virtual

This can be called each simulation frame with the entity's current sector information.

If it hasn't changed, the object will do nothing, but if it has, it will recalculate the sector vectors and bodyToSectorOffset. Values are in radians.

virtual DtReal DtSimSector::sectorSize ( ) const

virtual

Size of the sector in radians.

virtual DtReal DtSimSector::sectorCenter ( ) const

virtual

Center of the sector's center in radians.

virtual const DtVector& DtSimSector::centerVector ( ) const

virtual

Gives the center of the sector as a normalized vector in body coordinates.

virtual bool DtSimSector::inSector ( DtReal  angle ) const

virtual

Is this angle within the sector.

virtual bool DtSimSector::inSector ( DtVector  bodyVector ) const

virtual

Is this vector (body coordinates) in the sector.

virtual bool DtSimSector::inSector ( const DtVector &  localPoint, const DtVector &  parentLocation, const DtDcm &  localToBody  ) const

virtual

Is this point (world coordinates) in the sector.

virtual DtReal DtSimSector::bodyToSector ( DtReal  angle ) const

virtual

Converts an angle in body coordinates to an angle in sector coordinates.

virtual DtReal DtSimSector::sectorToBody ( DtReal  angle ) const

virtual

Converts an angle in sector coordinates to an angle in body coordinates.

virtual void DtSimSector::getSelf ( DtlObjPtr  args, const DtFilename &  searchPath, const DtVariableBindingsList &  variableBindings  )

protectedvirtual

Override, so that after read can call setSector to set up variables.

Reimplemented from DtReaderWriter.
