class Surface from ShapeCustom
|
|
|
|
---Purpose: Converts a surface to the analitical form with given
|
|
-- precision. Conversion is done only the surface is bspline
|
|
-- of bezier and this can be approximed by some analytical
|
|
-- surface with that precision.

is
|
|
|
|
Create returns Surface from ShapeCustom;
|
|

Create (S: Surface from Geom) returns Surface from ShapeCustom;

|
|
Init (me: in out; S: Surface from Geom);
|
|
|
|
Gap (me) returns Real;
|
|
---C++: inline
|
|
---Purpose: Returns maximal deviation of converted surface from the original
|
|
-- one computed by last call to ConvertToAnalytical
|
|
|
|
ConvertToAnalytical (me: in out; tol: Real;
|
|
substitute: Boolean)
|
|
returns Surface from Geom;
|
|
---Purpose: Tries to convert the Surface to an Analytic form
|
|
-- Returns the result
|
|
-- Works only if the Surface is BSpline or Bezier.
|
|
-- Else, or in case of failure, returns a Null Handle
|
|
--
|
|
-- If <substitute> is True, the new surface replaces the actual
|
|
-- one in <me>
|
|
--
|
|
-- It works by analysing the case which can apply, creating the
|
|
-- corresponding analytic surface, then checking coincidence
|
|
-- Warning: Parameter laws are not kept, hence PCurves should be redone
|
|
|
|
ConvertToPeriodic (me: in out; substitute: Boolean; preci: Real = -1)
|
|
returns Surface from Geom;
|
|
---Purpose: Tries to convert the Surface to the Periodic form
|
|
-- Returns the resulting surface
|
|
-- Works only if the Surface is BSpline and is closed with
|
|
-- Precision::Confusion()
|
|
-- Else, or in case of failure, returns a Null Handle
