class MakeHyperbola from GC inherits Root from GC
|
|
|
|
---Purpose :This class implements construction algorithms for a hyperbola in
|
|
-- 3D space. The result is a Geom_Hyperbola hyperbola.
|
|
-- A MakeHyperbola object provides a framework for:
|
|
-- - defining the construction of the hyperbola,
|
|
-- - implementing the construction algorithm, and
|
|
-- - consulting the results. In particular, the Value
|
|
-- function returns the constructed hyperbola.
|
|
-- To define the main branch of an hyperbola.
|
|
-- The parameterization range is ]-infinite,+infinite[
|
|
-- It is possible to get the other branch and the two conjugate
|
|
-- branches of the main branch.

|
|
-- The major radius is the distance between the Location point
|
|
-- of the hyperbola C and the apex of the Main Branch (or the
|
|
-- Other branch). The major axis is the XAxis.
|
|
-- The minor radius is the distance between the Location point
|
|
-- of the hyperbola C and the apex of the First (or Second)
|
|
-- Conjugate branch. The minor axis is the YAxis.
|
|
-- The major radius can be lower than the minor radius.

|
|
-- - its major axis is defined by Center and S1,
|
|
