Constructor & Destructor Documentation

Emma::Line::Line (   )  [inline]

virtual Emma::Line::~Line (   )  [inline, virtual]

EMMA_EXPORT Emma::Line::Line (  const Fusion::Vec3f &  p0, const Fusion::Vec3f &  p1 )

Construct a line from two points lying on the line. If you want to construct a line from a position and a direction, use Line(p, p + d). Line is directed from p0 to p1.
