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.
uses
Surface from Geom
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
fields
mySurf: Surface from Geom;
