Member Function Documentation

D1()

static void BRepGProp_EdgeTool::D1 ( const BRepAdaptor_Curve &  C, const Standard_Real  U, gp_Pnt &  P, gp_Vec &  V1  )

static

Returns the point of parameter U and the first derivative at this point.

FirstParameter()

static Standard_Real BRepGProp_EdgeTool::FirstParameter ( const BRepAdaptor_Curve &  C )

static

Returns the parametric value of the start point of the curve. The curve is oriented from the start point to the end point.

IntegrationOrder()

static Standard_Integer BRepGProp_EdgeTool::IntegrationOrder ( const BRepAdaptor_Curve &  C )

static

Returns the number of Gauss points required to do the integration with a good accuracy using the Gauss method. For a polynomial curve of degree n the maxima of accuracy is obtained with an order of integration equal to 2*n-1.

Intervals()

static void BRepGProp_EdgeTool::Intervals ( const BRepAdaptor_Curve &  C, TColStd_Array1OfReal &  T, const GeomAbs_Shape  S  )

static

Stores in <T> the parameters bounding the intervals of continuity <S>.

The array must provide enough room to accomodate for the parameters. i.e. T.Length() > NbIntervals()

LastParameter()

static Standard_Real BRepGProp_EdgeTool::LastParameter ( const BRepAdaptor_Curve &  C )

static

Returns the parametric value of the end point of the curve. The curve is oriented from the start point to the end point.

NbIntervals()

static Standard_Integer BRepGProp_EdgeTool::NbIntervals ( const BRepAdaptor_Curve &  C, const GeomAbs_Shape  S  )

static

Returns the number of intervals for continuity <S>. May be one if Continuity(me) >= <S>

Value()

static gp_Pnt BRepGProp_EdgeTool::Value ( const BRepAdaptor_Curve &  C, const Standard_Real  U  )

static

Returns the point of parameter U on the loaded curve.
