Member Function Documentation

void makVrv::DtBoundingBox::invalidate ( )

Mark the bounds invalid by setting all lower dimensions greater than the upper dimensions.

bool makVrv::DtBoundingBox::valid ( ) const

Is the bounds valid.

bool makVrv::DtBoundingBox::contains	(	float	x,
		float	y
	)		const

Does this bounding box contain the point.

DtBoundingBox& makVrv::DtBoundingBox::operator+= ( const Dt2dPoint & vector )

Move the Bounding Box by a vector.

DtBoundingBox& makVrv::DtBoundingBox::operator|= ( const DtBoundingBox & other )

Combine the two boxes together.

void makVrv::DtBoundingBox::centerOn ( Dt2dPoint pos )

Move the box's center point to the position, without changing the size.

void makVrv::DtBoundingBox::expandTo	(	float	width,
		float	height
	)

Expand the boxes size around its current center to have a width and height specified.
