Method inter

Geometry/Geometry 3D.cpp:187–190

returns the intersection point of the line with plane p assuming plane and line are not parallel

    // returns the intersection point of the line with plane p
    // assuming plane and line are not parallel
    p3 inter(plane p) { 
        // assert((d | p.n) != 0); // no intersection if parallel
        return o - d * p.side(o) / (d | p.n); 
    }
};

// smallest distance between two lines
