d3 rat point p.translate(const rat vector& v)
returns p + v, i.e., p translated by vector v
Precondition: v.dim() = 3.
d3 rat point
p + const rat vector& v
returns p translated by vector v
Precondition: v.dim() = 3.
d3 rat point
p − const rat vector& v
returns p translated by vector −v
Precondition: v.dim() = 3.
rational p.sqr dist(const d3 rat point& q)
returns the squared distance between p and q.
rational p.xdist(const d3 rat point& q)
returns the x-distance between p and q.
rational p.ydist(const d3 rat point& q)
returns the y-distance between p and q.
rational p.zdist(const d3 rat point& q)
returns the z-distance between p and q.
rat vector
p − const d3 rat point& q
returns the difference vector of the coordinates.
ostream&
ostream& O ≪ const d3 rat point& p
writes the homogeneous coordinates (x, y, z, w) of p to
output stream O.
istream&
istream& I ≫ d3 rat point& p
reads the homogeneous coordinates (x, y, z, w) of p
from input stream I.
