Static Public Member Functions | |
| static HomgPoint2D | read (vcl_istream &, bool is_homogeneous=false) |
| read from vcl_istream. Default is to assume that points are nonhomogeneous. | |

| Static method to set the default tolerance used for infinitesimal checks. | |
Static Public Attributes | |

| bool HomgPoint2D::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.

| bool HomgPoint2D::get_nonhomogeneous | ( | double & | ex, | |
| double & | ey | |||
| ) | const |
Return the non-homogeneous coordinates of the point.
If the point is at infinity, return false.

Rescale point (defaults to w = 1).
If the point is at infinity, return false
