Detailed Description

Represents a directed line in 3D space.

Constructor & Destructor Documentation

EMMA_EXPORT 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.

Member Function Documentation

EMMA_EXPORT bool getClosestPoints (  const Line &  line2, Fusion::Vec3f &  ptOnThis, Fusion::Vec3f &  ptOnLine2 )  const

Find closest points between the two lines. Return false if they are parallel, otherwise return true.
