Create (S : Shape from TopoDS;

Relatif : Boolean from Standard = Standard_False;
Ang : Real from Standard = 0.5)
returns IncrementalMesh from BRepMesh;
---Purpose: If the boolean <Relatif> is True, the
-- deflection used for the polygonalisation of
-- each edge will be <D> * Size of Edge.
-- the deflection used for the faces will be the maximum
-- deflection of their edges.

returns Boolean from Standard;

---Purpose: Builds the incremental mesh of the shape
IsModified (me)

---Purpose: Locate a correct discretisation if it exists
-- Set no one otherwise
Update (me : mutable;
F : Face from TopoDS)
is static private;
---Purpose: If the face is not correctly triangulated, or
-- if one of its edges is to be discretisated
-- correctly, the triangulation of this face is
-- built.
GetStatusFlags (me)
returns Integer from Standard

SetParallel ( me : mutable;

---Purpose:
-- Request algorithm to launch in multiple threads to improve performance.
IsParallel (me)
returns Boolean from Standard;
---Purpose:
-- Returns the multi-threading usage flag.

-- Plugin interface

---Purpose:
-- Plugin interface for the Mesh Factories.
IsParallelDefault (myclass)
returns Boolean from Standard;
---Purpose:
-- Returns multi-threading usage flag set by default in
-- Discret() static method (thus applied only to Mesh Factories).
SetParallelDefault (myclass;

---Purpose:
-- Setup multi-threading usage flag set by default in
