| class | gce_MakeParab2d |
Implements construction algorithms for gp_Parab2d. The parabola is infinite and represented in a local 2D coordinate system. The XAxis is the symmetry axis directed from vertex to focus, and the YAxis is parallel to the directrix. The equation in local coordinates is: Y**2 = (2*P) * X, where P is the distance between focus and directrix. The focal length F = P / 2 is the distance from vertex to focus. More... | |
