Adaptor2d_Curve2d, Adaptor3d_Curve and Adaptor3d_Surface now inherit Standard_Transient. Interfaces Adaptor2d_HCurve2d, Adaptor3d_HCurve, Adaptor3d_HSurface and their subclasses are now aliases to Adaptor2d_Curve2d, Adaptor3d_Curve and Adaptor3d_Surface. Removed numerous unsafe reinterpret casts. Generic classes Adaptor3d_GenHCurve, Adaptor3d_GenHSurface, Adaptor2d_GenHCurve2d have been removed. Several redundant .lxx files have been merged into .hxx. Removed obsolete adaptor classes with H suffix.

//! This class processes data resulting from
|
|
//! Blend_CSWalking taking in consideration the Surface
|
|
//! supporting the curve to detect the breakpoint.
|
|
//!
|
|
//! The criteria of distribution of points on the line are detailed
|
|
//! because it is to be used in the calculatuon of values approached
|
|
//! by an approximation of functions continued basing on
|
|
//! Blend_SurfRstFunction.
|
|
//!
|
|
//! Thus this pseudo path necessitates 3 criteria of regrouping :
|
|
//!
|
|
//! 1) exit of the domain of the curve
|
|
//!
|
|
//! 2) exit of the domain of the surface
|
|
//!
|
|
//! 3) stall as there is a solution to the problem
|
|
//! surf/surf within the domain of the surface
|
|
//! of support of the restriction.
|
|
//!
|
|
//! Construction of a BRepBlend_Line between a surface and
|
|
//! a pcurve on surface from an approached
|
|
//! starting solution. The output entries of this builder
|
|
//! are of the same nature as of the traditional walking
|
|
//! but the requirements on the Line are not the same
|
|
//! If the determination of validity range is always
|
|
//! guaranteed, the criteria of correct repartition of sections
|
|
//! before smoothing are not respected. The resulting Line
|
|
//! is f(t) oriented.
