class Vertex from ShapeBuild
---Purpose: Provides low-level functions used for constructing vertices
uses
Pnt from gp,
Vertex from TopoDS
is
CombineVertex ( me; V1, V2: Vertex from TopoDS; tolFactor: Real = 1.0001 )
returns Vertex from TopoDS;
---Purpose: Combines new vertex from two others. This new one is the
-- smallest vertex which comprises both of the source vertices.
-- The function takes into account the positions and tolerances
-- of the source vertices.
-- The tolerance of the new vertex will be equal to the minimal
-- tolerance that is required to comprise source vertices
-- multiplied by tolFactor (in order to avoid errors because
-- of discreteness of calculations).
CombineVertex ( me; pnt1, pnt2: Pnt from gp; tol1, tol2: Real;
tolFactor: Real = 1.0001 )
returns Vertex from TopoDS;
---Purpose: The same function as above, except that it accepts two points
-- and two tolerances instead of vertices
end Vertex;
