generic class ToolPolyhedron from Intf (Polyhedron as any)
|
|
|
|
---Purpose: Describes the signature of a polyedral surface with only
|
|
-- triangular facets and the information necessary to compute
|
|
-- the interferences.
|
|
|
|
|
|
uses XYZ from gp,
|
|
Pnt from gp,
|
|
Box from Bnd,
|
|
HArray1OfBox from Bnd
|
|
|
|
|
|
raises OutOfRange from Standard
|
|
|
|
|
|
is Bounding (myclass; thePolyh : Polyhedron)
|
|
returns Box from Bnd;
|
|
---Purpose: Returns the bounding box of the ToolPolyhedron.
|
|
|
|
ComponentsBounding
|
|
(myclass; thePolyh : Polyhedron)
|
|
returns HArray1OfBox from Bnd;
|
|
---Purpose: Returns the array of boxes. The box <n> corresponding
|
|
-- to the triangle <n>.
|
|
|
|
|
|
DeflectionOverEstimation
|
|
(myclass; thePolyh : Polyhedron)
|
|
returns Real from Standard;
|
|
---Purpose: Returns the tolerance of the polygon.
|
|
|
|
|
|
-- Structure needings :
|
|
|
|
NbTriangles (myclass; thePolyh : Polyhedron)
|
|
returns Integer from Standard;
|
|
---Purpose: Returns the number of triangles in this polyedron.
|
|
|
|
|
|
Triangle (myclass; thePolyh : Polyhedron;
|
|
Index : in Integer from Standard;
|
|
P1,P2,P3 : out Integer from Standard)
|
|
raises OutOfRange from Standard;
|
|
---Purpose: Returns the indices of the 3 points of the triangle of
|
|
-- address Index in the ToolPolyhedron.
|
|
|
|
|
|
Point (myclass; thePolyh : Polyhedron;
|
|
Index : in Integer)
|
|
returns Pnt from gp
|
|
raises OutOfRange from Standard;
|
|
---Purpose: Returns the point of index i in the polyedron.
|
|
|
|
|
|
TriConnex (myclass; thePolyh : Polyhedron;
|
|
Triang : in Integer;
|
|
Pivot,Pedge : in Integer;
|
|
TriCon : out Integer;
|
|
OtherPedge : out Integer)
|
|
returns Integer
|
|
raises OutOfRange from Standard;
|
|
---Purpose: Returns the triangle <Tricon> connected to the triangle
|
|
-- <Triang> by the edge <Pivot><Pedge>. The third point of
|
|
-- the connected triangle is returned in <OtherPedge> (Used to
|
|
-- turn around a vertex). When the edge <Pivot><Pedge> is
|
|
-- free (no connected triangle) <Tricon> is null. In this
|
|
-- case the function returns the triangle on the free bound of
|
|
-- the polyhedron connected to <Triang> by vertex <Pivot>.
