(

)

const

Given a direction vector in local coordinates, this function determines which corner of the bounding volume is farthest from the object origin in that direction, i.e.

if all of the bv vertices are projected onto a ray from the origin in the given direction, which one is farthest along the ray in the + direction.

const Dt3dBoundingVolume& DtEntityCollision::obstructionBoundingVolume ( ) const

virtual

Implements DtCollision.

Dt3dBoundingVolume& DtEntityCollision::obstructionBoundingVolume ( )

virtual

Implements DtCollision.

void DtEntityCollision::setDistanceSquared ( double  distanceSquared )

virtual

Implements DtCollision.

double DtEntityCollision::distanceSquared ( ) const

virtual

Implements DtCollision.

virtual const DtDcm& DtEntityCollision::obstructionLocalOrientationMatrix ( ) const

virtual

Adds to the distance...argument is a distance, not a distance-squared.

So if the distance is 7, then distanceSquared() will return 49; if addDistance(2) is then called, then after distanceSquared() will return 81. fixme
