C++ (Cpp) Hyperplane::normal примеры использования

Пример #1

Vector3d getPlaneIntersection( const Hyperplane<double,3> &plane1, const Hyperplane<double,3> &plane2, double lambda)
{
	double dot = plane1.normal().dot(plane2.normal());
	Vector3d cross = plane1.normal().cross(plane2.normal());
	double c1 = (plane1.offset() - plane2.offset()*dot )/(1.0-dot*dot);

	double c2 = (plane2.offset() - plane1.offset()*dot )/(1.0-dot*dot);

	Vector3d r = (c1*plane1.normal() + c2*plane2.normal() ) + lambda*(cross);

	return r;
}

Пример #2

Vector3d getReflected(const Vector3d &p, const Hyperplane<double,3> &plane)
{   Vector3d r = p- 2*plane.signedDistance(p)*plane.normal();
	return r;
}
