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.
