const

Return the non-homogeneous coordinates of the point as a vector of doubles.

If the point is at infinity, return a vector of Homg::infinity

Definition at line 41 of file HomgPoint3D.cxx.

bool HomgPoint3D::get_nonhomogeneous	(	double &	vx,
		double &	vy,
		double &	vz
	)		const

Return the non-homogeneous coordinates of the point.

If the point is at infinity, return false and set the output values to Homg::infinity.

bool HomgPoint3D::ideal

(

double

tol = 1e-12

const [inline]

Return true iff the point is the point at infinity.

If tol == 0, w() must be exactly 0. Otherwise, tol is used as tolerance value (default: 1e-12), and is checked.
