Static Public Member Functions

static DEFINE_STANDARD_ALLOC
Standard_Integer 
ComputeVV (const TopoDS_Vertex &V1, const TopoDS_Vertex &V2)
 Computes distance between vertex V1 and vertex V2,
if the distance is less than sum of vertex tolerances
returns zero,
otherwise returns negative value


static Standard_Boolean HasInternalEdge (const TopoDS_Wire &aW)
 Returns True if wire aW contains edges
with INTERNAL orientation


static void MakeFaceFromWireAndFace (const TopoDS_Wire &aW, const TopoDS_Face &aF, TopoDS_Face &aFNew)
 Build a face based on surface of given face aF
and bounded by wire aW


static TopAbs_State ClassifyPointByFace (const TopoDS_Face &aF, const gp_Pnt2d &P)
 


static Standard_Boolean IsVertex (const TopoDS_Edge &E, const Standard_Real t)
 Computes square distance between a point on the edge E
corresponded to parameter t and vertices of edge E.
Returns True if this distance is less than square
tolerance of vertex, otherwise returns false.


static Standard_Boolean IsVertex (const TopoDS_Edge &E, const TopoDS_Vertex &V, const Standard_Real t)
 Returns True if square distance between vertex V
and a point on the edge E corresponded to parameter t
is less than square tolerance of V


static Standard_Boolean IsVertex (const IntTools_CommonPrt &aCmnPrt)
 Returns True if IsVertx for middle parameter of fist range
and first edge returns True
and if IsVertex for middle parameter of second range and
second range returns True,
otherwise returns False


static Standard_Boolean IsMiddlePointsEqual (const TopoDS_Edge &E1, const TopoDS_Edge &E2)
 Gets boundary of parameters of E1 and E2.
Computes 3d points on each corresponded to average parameters.
Returns True if distance between computed points is less than
sum of edge tolerance, otherwise returns False.


static Standard_Boolean IsVertex (const gp_Pnt &aP, const Standard_Real aTolPV, const TopoDS_Vertex &aV)
 Returns True if the distance between point aP and
vertex aV is less or equal to sum of aTolPV and
vertex tolerance, otherwise returns False


static Standard_Real IntermediatePoint (const Standard_Real aFirst, const Standard_Real aLast)
 Returns some value between aFirst and aLast


static Standard_Integer SplitCurve (const IntTools_Curve &aC, IntTools_SequenceOfCurves &aS)
 Split aC by average parameter if aC is closed in 3D.
Returns positive value if splitting has been done,
otherwise returns zero.


static void RejectLines (const IntTools_SequenceOfCurves &aSIn, IntTools_SequenceOfCurves &aSOut)
 Puts curves from aSIn to aSOut except those curves that
are coincide with first curve from aSIn.


static Standard_Boolean IsDirsCoinside (const gp_Dir &D1, const gp_Dir &D2)
 Returns True if D1 and D2 coinside


static Standard_Boolean IsDirsCoinside (const gp_Dir &D1, const gp_Dir &D2, const Standard_Real aTol)
 Returns True if D1 and D2 coinside with given tolerance


static Standard_Boolean IsClosed (const Handle< Geom_Curve > &aC)
 Returns True if aC is BoundedCurve from Geom and
the distance between first point
of the curve aC and last point
is less than 1.e-12


static Standard_Real CurveTolerance (const Handle< Geom_Curve > &aC, const Standard_Real aTolBase)
 Returns adaptive tolerance for given aTolBase
if aC is trimmed curve and basis curve is parabola,
otherwise returns value of aTolBase
