Macro NO_CXX_EXCEPTION was removed from code. Method Raise() was replaced by explicit throw statement. Method Standard_Failure::Caught() was replaced by normal C++mechanism of exception transfer. Method Standard_Failure::Caught() is deprecated now. Eliminated empty constructors. Updated samples. Eliminate empty method ChangeValue from NCollection_Map class. Removed not operable methods from NCollection classes.

//! This class implements the following algorithms used
|
|
//! to create a ConicalSurface from Geom.
|
|
//! * Create a ConicalSurface parallel to another and passing
|
|
//! through a point.
|
|
//! * Create a ConicalSurface parallel to another at a distance
|
|
//! <Dist>.
|
|
//! * Create a ConicalSurface by 4 points.
|
|
//! * Create a ConicalSurface by its axis and 2 points.
|
|
//! * Create a ConicalSurface by 2 points and 2 radius.
|
|
//! The local coordinate system of the ConicalSurface is defined
|
|
//! with an axis placement (see class ElementarySurface).
|
|
//!
|
|
//! The "ZAxis" is the symmetry axis of the ConicalSurface,
|
|
//! it gives the direction of increasing parametric value V.
|
|
//! The apex of the surface is on the negative side of this axis.
|
|
//!
|
|
//! The parametrization range is :
|
|
//! U [0, 2*PI], V ]-infinite, + infinite[
|
|
//!
|
|
//! The "XAxis" and the "YAxis" define the placement plane of the
|
|
//! surface (Z = 0, and parametric value V = 0) perpendicular to
|
|
//! the symmetry axis. The "XAxis" defines the origin of the
|
|
//! parameter U = 0. The trigonometric sense gives the positive
|
|
//! orientation for the parameter U.
|
|
//!
|
|
//! When you create a ConicalSurface the U and V directions of
|
|
//! parametrization are such that at each point of the surface the
|
|
//! normal is oriented towards the "outside region".
