ool S.insphere(const d3 point& p)
returns true, if p lies in the interior of the sphere
through p1 , p2 , p3 , p4 .
double S.vol( ) returns the signed volume of the simplex.
d3 simplex S.reflect(const d3 point& p, const d3 point& q, const d3 point& v)
d3 simplex S.reflect(const d3 point& p)
d3 simplex S.translate(const vector& v)
returns S reflected across the plane through (p, q, v).
returns S reflected across point p.
returns S translated by vector v.
Precond. : v.dim( ) = 3.
d3 simplex
S.translate(double dx, double dy, double dz)
returns S translated by vector (dx, dy, dz).
d3 simplex S + const vector& v returns S translated by vector v.
d3 simplex S − const vector& v returns S translated by vector −v.
