Detailed Description

may be associated with a drawObj.. not a drawObj itself.. all methods work in a local coordinate system - push appropriate xform onto stack before calling draw(), also transform any points to local coordinates before calling contains..

Member Function Documentation

void BBox::addBBox (  BBox *const   b2  )  [inline]

enlarge the bbox if necessary to contain this other bbox

void BBox::addBBox (  const BBox  b2  )  [inline]

enlarge the bbox if necessary to contain this other bbox

void BBox::addPt (  const Wpt  p  )  [inline]

enlarge the bbox if necessary to contain this point

Wpt BBox::center (   )  const [inline]

int BBox::contains (  const Wpt  pt, const Wtransf  xform )  [inline]

for intersection tests - return true if pt lies within the bbox transformed by xform

int BBox::contains (  const Wpt  pt  )  [inline]

for intersection tests - return true if pt lies within the bbox

void BBox::draw (   )  [inline]

draws the bounding box. this does not alter the GL state - it is safe for G3D.

Wpt BBox::minPt (   )  const [inline]

void BBox::print (   )  [inline]

void BBox::reset (   )  [inline]

reset the bbox to be a point

void BBox::transformBox (  const Wtransf  transform  )  [inline]

transform a bounding box by a given transformation

double BBox::volume (  const Wtransf  m  )  [inline]

volume of the bbox transformed by m
