Detailed Description

template<class SegmentScalarType>
class vcg::Segment2< SegmentScalarType >

Templated class for 3D segment. This is the class for a segment in 3D space. A Segment is stored just as its two extrema (Point3).

Parameters:

SegmentScalarType

(template parameter) Specifies the type of scalar used to represent coords.
