Detailed Description

Describes a branch of a hyperbola in the plane (2D space). A hyperbola is defined by its major and minor radii and, as with any conic curve, is positioned in the plane with a coordinate system (gp_Ax22d object) where:

the origin is the center of the hyperbola,
the "X Direction" defines the major axis, and
the "Y Direction" defines the minor axis. This coordinate system is the local coordinate system of the hyperbola. The branch of the hyperbola described is the one located on the positive side of the major axis. The orientation (direct or indirect) of the local coordinate system gives an explicit orientation to the hyperbola, determining the direction in which the parameter increases along the hyperbola. The Geom2d_Hyperbola hyperbola is parameterized as follows: P(U) = O + MajRad*Cosh(U)*XDir + MinRad*Sinh(U)*YDir where:
P is the point of parameter U,
O, XDir and YDir are respectively the origin, "X Direction" and "Y Direction" of its local coordinate system,
MajRad and MinRad are the major and minor radii of the hyperbola. The "X Axis" of the local coordinate system therefore defines the origin of the parameter of the hyperbola. The parameter range is ] -infinite,+infinite [. The following diagram illustrates the respective positions, in the plane of the hyperbola, of the three branches of hyperbolas constructed using the functions OtherBranch, ConjugateBranch1 and ConjugateBranch2: ^YAxis | FirstConjugateBranch | Other | Main ------------------— C ------------------—>XAxis Branch | Branch | SecondConjugateBranch | Warning The value of the major radius (on the major axis) can be less than the value of the minor radius (on the minor axis). See Also GCE2d_MakeHyperbola which provides functions for more complex hyperbola constructions gp_Ax22d gp_Hypr2d for an equivalent, non-parameterized data structure
