void Init(IPointMatrix poles)
void Init1(IPointMatrix_DG poles, IMatrix_DG weights)
IPartialBezierProps_DG GetAxialProps(VARIANT_BOOL u)
PairInt_DG GetPoleMatrixSize()
Point_DG GetPole(int indexU, int indexV)
The indices must be in [0, GetAxialProps(u).GetPoleCount()-1] range.
void SetPole(int indexU, int indexV, Point_DG point)
The indices must be in [0, GetAxialProps(u).GetPoleCount()-1] range.
void SetPole1(int indexU, int indexV, Point_DG point, double weight)
The indices must be in [0, GetAxialProps(u).GetPoleCount()-1] range.
IPointMatrix_DG GetPoles()
double GetWeight(int indexU, int indexV)
The indices must be in [0, GetAxialSplineProps(u).GetPoleCount()-1] range.
void SetWeight(int indexU, int indexV, double weight)
The indices must be in [0, GetAxialSplineProps(u).GetPoleCount()-1] range.
IMatrix_DG GetWeights()
Point_DG GetPoint(DG2D uv)
Vect_DG GetNormal(DG2D uv)
void GetJet1(DG2D uv, Point_DG point, out Vect_DG d1u, out Vect_DG d1v)
Returns point and derivatives at the uv parameters
void GetJet2(DG2D uv, Point_DG point, out Vect_DG d1u, out Vect_DG d1v, out Vect_DG d2u, out Vect_DG d2v, out Vect_DG d2uv)
Returns point and derivatives at the uv parameters
Vect_DG GetJetN(DG2D uv, int Nu, int Nv)
Returns point and derivatives of the specified order at the uv parameters
ICurve_DG GetIsoCurve(bool u, double paramAt)
If u is true, returns curve v->S(paramAt, v) parametrised by v.
(u, v)->S(u,v) here denotes
the surface mapping as defined by GetPoint() method above.
paramAt must be within the range returned by IUVSurface_DG.GetParameterRange(true,min,max).
The returned curve will have range IUVSurface_DG.GetParameterRange(false,min,max).
Conversely, if u is false, the method returns curve u->S(u, paramAt) parametrised by u.
void SwapUV()
Exchanges the u and v parametric directions. As a consequence: The pole and weight tables are transposed,
the knot and multiplicity tables are exchanged, degrees of continuity, and rational, periodic and uniform characteristics are exchanged, and the orientation of the surface is inverted.
void Transform(IFrame_DG transform)
Applies the transformation to this surface
