class | gce_MakeParab |
This class implements the following algorithms used to create Parab from gp. Defines the parabola in the parameterization range : ]-infinite, +infinite[ The vertex of the parabola is the "Location" point of the local coordinate system (axis placement) of the parabola. The "XDirection" and the "YDirection" of this system define the plane of the parabola. The "XAxis" of the parabola ("Location", "XDirection") is the axis of symmetry of the parabola. The Xaxis is oriented from the vertex of the parabola to the Focus of the parabola. The "YAxis" of the parabola ("Location", "YDirection") is parallel to the directrix of the parabola. The equation of the parabola in the local coordinates system is Y**2 = (2*P) * X P is the distance between the focus and the directrix of the parabola (called Parameter). The focal length F = P/2 is the distance between the vertex and the focus of the parabola. More... |
