Member Function Documentation

RmVector3D RmBoundBox::GetCenter (   )

Center of boundbox. Return center of bound box Returns: Center point of boundbox See also: RmVector3D

void RmBoundBox::GetCornerVertices (  RmVector3D *  pCornerVerts  )

Get corner vertices. Get corner vertices ( 8 of them ) and put them to pCornerVerts It is assumed that pCornerVerts is large enough to hold 8 vectors Parameters: pCornerVertices  8 vector table to receive corner of boundbox See also: RmVector3D Returns: None

const RmVector3D& RmBoundBox::GetMax (   )  const [inline]

Maximum point. Accessor for maximum point Returns: Maximum point See also: RmVector3D

RmVector3D& RmBoundBox::GetMax (   )  [inline]

Maximum point. Accessor for maximum point Returns: Maximum point See also: RmVector3D

const RmVector3D& RmBoundBox::GetMin (   )  const [inline]

Minimum point. Accessor for minimum point Returns: Minimum point See also: RmVector3D

RmVector3D& RmBoundBox::GetMin (   )  [inline]

Minimum point. Accessor for minimum point Returns: Minimum point See also: RmVector3D

RmVector3D RmBoundBox::GetRange (   )

Range f boundbox. Return range ( max - min ) of bound box Returns: Range of boundbox See also: RmVector3D

bool RmBoundBox::IsEmpty (   )  const [inline]

Is empty. Returns if Boundbox is empty Returns: true if boundbox is empty

RmBoundBox RmBoundBox::operator * (  const RmMatrix4x4 &  mat  )

Transform boundbox. Transformed BoundBox by matrix Parameters: mat  Matrix to transform boundbox with Returns: New boundbox

void RmBoundBox::SetEmpty (  bool  bEmpty  )  [inline]

Set empty. Set empty flag Parameters: bEmpty  Flag for empty or not Returns: None

void RmBoundBox::Union (  const RmBoundBox &  box  )

Do union operation. If any corner of given boundbox is outside of current boundbox, expand bound box to include the source boundbox Parameters: box  Boundbox to do Union Returns: None

void RmBoundBox::Union (  const RmVector3D &  point  )

Do union operation. If given point is outside of current boundbox, expand bound box to include given point Parameters: point  Point to do Union Returns: None
