Generic classes: "GccIter_Circ2d2TanOn", "GccIter_Circ2d3Tan", "GccIter_Lin2d2Tan", "GccIter_Lin2dTanObl" from "GccIter" package were converted to the non-generic classes and moved to the "Geom2dGcc" package. Names of this classes were changed to: "Geom2dGcc_Circ2d2TanOnIter", "Geom2dGcc_Circ2d3TanIter", "Geom2dGcc_Lin2d2TanIter", "Geom2dGcc_Lin2dTanOblIter". And their internal classes: "GccIter_FunctionTanCuCuOnCu", "GccIter_FunctionTanCuCuCu", "GccIter_FunctionTanCirCu", "GccIter_FunctionTanCuCu", "GccIter_FunctionTanCuPnt", "GccIter_FunctionTanObl" also converted to the non-generic and moved to the "Geom2dGcc" package(their declarations were moved to "Geom2dGcc.cdl"). Enumerations" Type1, Type2 and Type3 were moved to "Geom2dGcc.cdl". Package "GccIter" was deleted.

class Lin2dTanObl from Geom2dGcc
|
|
|
|
---Purpose: This class implements the algorithms used to
|
|
-- create 2d line tangent to a curve QualifiedCurv and
|
|
-- doing an angle Angle with a line TheLin.
|
|
-- The angle must be in Radian.
|
|
-- Describes functions for building a 2D line making a given
|
|
-- angle with a line and tangential to a curve.
|
|
-- A Lin2dTanObl object provides a framework for:
|
|
-- - defining the construction of 2D line(s),
|
|
-- - implementing the construction algorithm, and
|
|
-- - consulting the result(s).
