Member Function Documentation

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.

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.

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.

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()

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.

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>

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.
