Nurbs3d Methods

The methods of the Nurbs3d class are listed below. For a complete list of Nurbs3d class members, see the Nurbs3d Members topic.

Public Instance Methods

Changed (inherited from Curve3D) This method is called, when the curve is changed. It fires the event OnChanged
Clone (inherited from Curve3D) Produces an exact copy of the curve by using the BinaryFormatter. So you have to mark a new instance of Curve with the attribute [Serializable].
Close Closes a Nurbs by changing some Controlpoints and some Weights.
Copy (inherited from Curve3D) Copy the Curve. Some instances override this method.
DefaultKnots (inherited from BSpline3d) Gets the DefaultKnots.
Derivation The Derivation of a Nurbs
Distance (inherited from Curve3D)Overloaded. This method calculates the distance of a LineType to a Curve only in case, when the distance is smaller then MaxDist, otherwise big will be returned. You can imagine a cylinders with radius MaxDist around the Curve. If the line goes through the "curved" cylinder, then the distance will be calculated and returned.
Equals (inherited from Object) 
GetHashCode (inherited from Object) 
GetMaxrect (inherited from Curve3D)Overloaded. Gets a minimal Box, which contains a curve, transformed by a transformation.
GetType (inherited from Object) 
InsertPoint (inherited from Curve3D) Inserts a point at the position, which is given by Param.
Invert (inherited from Curve3D) Inverts the orientation of a curve. The base-method is empty. You should override it in a derived class.
LengthToParam (inherited from Curve3D) Converts a length to a param, which can be used in the method Value.
NormalCross (inherited from Curve3D) Calculates a point of a Curve, which is nearest to "Point"
ParamToLength (inherited from Curve3D) Calculates the length of a part of the curve, which is given from 0 to the value param.
SetBorder (inherited from Curve3D) Restricts the Curve to the startpoint A and the endpoint B. The method works regular only if A and B are "close to the curve".
Slice (inherited from BSpline3d) Overrides the Slice-method.
ToArray (inherited from Curve3D) This method fills values, calculated by the function Value in an array, starting at index.
ToString (inherited from Object) 
ToxyzArray (inherited from Curve3D) Gets an array of Resolution+1 interpolationpoints.
Transform (inherited from BSpline3d) Overrides the Transform-method, whitch transforms the ControlControlPoints.
UniformKnots (inherited from BSpline3d) Gets the UniformKnots
Value Overrides the abstract Value function Valueof the curve class and retrieves the Bezierfunction of t depending on the control points ControlPoints.

Protected Instance Methods

Finalize (inherited from Object) 
getA (inherited from Curve3D) This is the virtual Get-Method of A. By default it calls 'Value(fromParam)'.
getAtang (inherited from BSpline3d) Overrides the getAtang and returns Points[1] - Points[0].
getB (inherited from Curve3D) This is the virtual Get-Method of B. By default, it provides 'Value(toParam)'.
getBtang (inherited from BSpline3d) Overrides the getAtang and returns Points[3] - Points[2].
GetMaxrect (inherited from Curve3D)Overloaded. Gets the smaller rectangle, which contains the curve.
getVisible (inherited from Curve3D) virtual getmethod of the property Visible
MemberwiseClone (inherited from Object) 
setA (inherited from BSpline3d) Overrides the method setA by setting the value of the Point[0];
setAtang (inherited from BSpline3d) Overrides the abstract getA-method and returns the point[0]. Overrides the setAtang-method
setB (inherited from BSpline3d) Overrides the setA-method by setting the endpoint to Points[3].
setBtang (inherited from BSpline3d) Overrides the setBtang by setting Points[2] to Points[3] - value;
SetClosed (inherited from Curve3D) Virtual Settermethod of Closed-property
SetControlPoints Overrides the SetControlPoints-method and makes sure, that the Weights are well defined.
setVisible (inherited from Curve3D) Virtual setmethod of the property Visible
SetWeights Virtual Set method of Weights.
