RegisteredCurves | Holds a list of curve types for copying curves and array of curves. A curve will be written in a stream and read from a stream. The basic concept contains the method LoadFromStream and SaveToStream By registrating Register(1, typeof(Line3)); Register(3, typeof(Bezier3D)); Register(4, typeof(QSpline3D)); Register(5, typeof(Nurbs3D)); Register(6, typeof(BSpline3D)); The curves can reconsturcted by calling the empty constructor |

FindType | Gets the associated type of an ID |

Register | Register a CurveType. |

registerAliases | Register "alias"-names for some types. |

Curve3D Constructor | Constructor without parameters. |

A | Gets the starting point of the curve by calling getA. |

Atang | Returns and sets the start tangent. See getAtang and Btang |

B | Gets the endpoint of the curve by calling getB. |

Btang | Returns and sets the end tangent. See getBtang and Atang. |

Closed | Gets and sets the information, that the curve is closed, ie A = B. |

CurveLength | Retrieves the length of the curve. |

fromParam | Retrieves and sets the starting parameter. All parameters are within the interval [fromParam, toParam]. Initial value is 0; |

Maxrect | A property, which calls GetMaxrect |

Neighbors | If a Curve3D is a contur curve of a Face this array contains both Neighbors. In generally this are two. |

Resolution | Retrieves and sets the resolution of the curve. The default value is 20. |

toParam | Retrieves and sets the end parameter. All parameters are within the interval [fromParam, toParam]. Initialvalue is 1; |

Visible | Several classes use this property and hide a curve, where visible is false. |

Changed | This method is called, when the curve is changed. It fires the event OnChanged |

Clone | 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]. |

Copy | Copy the Curve. Some instances override this method. |

Derivation | It returns the first deriavation of the function defined in the method Value. All parameter t are taken from the interval [fromParam,toParam]. |

Distance | 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 | Overloaded. Gets a minimal Box, which contains a curve, transformed by a transformation. |

GetType (inherited from Object) | |

InsertPoint | Inserts a point at the position, which is given by Param. |

Invert | Inverts the orientation of a curve. The base-method is empty. You should override it in a derived class. |

LengthToParam | Converts a length to a param, which can be used in the method Value. |

NormalCross | Calculates a point of a Curve, which is nearest to "Point" |

ParamToLength | Calculates the length of a part of the curve, which is given from 0 to the value param. |

SetBorder | 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 | This method trims the curve to the part between "from" and "to". The base-method sets fromParam = from and toParam = to. In general this is not the best solution. So it is better to override this method without calling to the base method. |

ToArray | This method fills values, calculated by the function Value in an array, starting at index. |

ToString (inherited from Object) | |

ToxyzArray | Gets an array of Resolution+1 interpolationpoints. |

Transform | Transforms a Curve with the transformation given by m. The method in the base class is empty. So you have to override this function, if you want to transform a Curve. |

Value | Its implement a function from R --> R³ public xyz Value(double t){ return new xyz(cos(t), sin(t),t); } public xyz Drivation(double t){ return new xyz(-sin(t), cos(t),1); }This example implements an screw curve. |

Finalize (inherited from Object) | |

getA | This is the virtual Get-Method of A. By default it calls 'Value(fromParam)'. |

getAtang | This method is the getMethod of the Atang-property, which retrieves the start tangent. By default Derivation(fromParam) is returned. |

getB | This is the virtual Get-Method of B. By default, it provides 'Value(toParam)'. |

getBtang | This method is the getMethod of the Btang-property, which retrieves the Endtangent. By default Derivaion(toParam) is returned. |

GetMaxrect | Overloaded. Gets the smaller rectangle, which contains the curve. |

getVisible | virtual getmethod of the property Visible |

MemberwiseClone (inherited from Object) | |

setA | This is the virtual setter method of the property A |

setAtang | This is the virtual setter method of the property Atang |

setB | This is the virtual setter method of the property B |

setBtang | This is the virtual set method of the property B |

SetClosed | Virtual Settermethod of Closed-property |

setVisible | Virtual setmethod of the property Visible |
