This algorithm converts a hyperbola into a rational Bspline curve. The hyperbola is an Hypr2d from package gp with the parametrization : P (U) = Loc + (MajorRadius * Cosh(U) * Xdir + MinorRadius * Sinh(U) * Ydir) where Loc is the location point of the hyperbola, Xdir and Ydir are the normalized directions of the local cartesian coordinate system of the hyperbola. KeyWords : Convert, Hyperbola, BSplineCurve, 2D . More...
