## Member Function Documentation

 std::pair< double, algebra::Vector3D > IMP::algebra::Torus3D::get_torus_distance ( Sphere3D sphere ) const

Computes distance and derivative of a sphere s relative to the surface of a torus with major radius R and minor radius r (on z=0, the inner and outer torus rings have radii R-r and R+r, respectively).

Returns
a tuple (d,v) s.t.: d = The shortest distance from any point on s to any point on the torus. If s penetrates the torus, the opposite of the maximal penetration depth is returnd. v = the normalized derivative vector of d
