Detailed Description

template<class FT>
class easy3d::GenericOrientedLine< FT >

OrientedLine implements plucker coordinates, which enables oriented lines to be compared.

The comparison, implemented by the side() function, is a predicate similar to the right hand rule. For instance, this class is used for the line-polygon intersection test. (See D.M.Y. Sommerville, Analytical Geometry of Three Dimensions. Cambridge University Press, 1959).

inlinestatic

"right hand rule" like predicate.

Returns

• +1 Positive side
• -1 for negative side.
