Operations

A model of this concept must provide:

Kernel::Vector_3 operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r)
 computes the unit normal of the vectorsq-p and r-p. More...
 

Member Function Documentation

Kernel::Vector_3 Kernel::ConstructUnitNormal_3::operator() ( const Kernel::Point_3 &  p,
const Kernel::Point_3 &  q,
const Kernel::Point_3 &  r 
)

computes the unit normal of the vectorsq-p and r-p.

This requires that Kernel::FT supports the sqrt operation.
