Detailed Description

template<class LineScalarType, bool NORM = false>
class vcg::Line2< LineScalarType, NORM >

Templated class for 2D lines. This is the class for infinite lines in 3D space. A Line is stored just as two Point2: an origin and a direction (not necessarily normalized).

Parameters:

	LineScalarType	(template parameter) Specifies the type of scalar used to represent coords.
	NORM,:	if on, the direction is always Normalized
