CurveExtruder overview

Public Instance Constructors

CurveExtruder Constructor Initializes a new instance of the CurveExtruder class.

Public Instance Fields

Bounds (inherited from Surface) Holds the Raster for BoundedCurves. This field will be calculated automatically by a call of new Raster(value.getxyArray(),new xy(0,0), 1 / (float)UResolution, 1 / (float)VResolution);
UPeriodicity (inherited from Surface) Some surfaces are periodically in the parameters. For example a Cone has a periode of 2*PI for the u-parameter. The UPeriodicity gets and sets this priodicity. If the value is 0 no periodicity is assumed.
VPeriodicity (inherited from Surface) Some surfaces are periodically in the parameters. For example a Cone has a periode of 2*PI for the u-parameter. The VPeriodicity gets and sets this priodicity. If the value is 0 no periodicity is assumed.

Public Instance Properties

Base (inherited from Surface) Gets and sets a base for the surface.
BoundedCurves (inherited from Surface) Defines a enclosing curve list. If this value is different from null, only the part inside the curves will be drawn by drawSurface.
Curve Sets or gets the curve that will be extruded.
DisplayList (inherited from Surface) Holds a displaylist, which was generated by Compile
Height retrieves or writes the height of the extruded object
TextureOffset (inherited from Surface) Sets or gets an offset for a texture
UFactor (inherited from Surface) The Ufactor normalizes the u parameter to [0,1]. This must be respected, when you define a Value, uDerivation or vDerivation. For example the Cone has a UFactor 2*PI. in the Value method we have
double x = System.Math.Cos(u * UFactor);
double y = System.Math.Sin(u * UFactor);
double z = v * VFactor;
UResolution (inherited from Surface) Defines a Resolution for the u parameter Default is 20;
VFactor (inherited from Surface) The Vfactor normalizes the v parameter to [0,1]. This must be respected, when you define a Value, uDerivation or vDerivation. For example the Cone has a UFactor 2*PI. in the Value method we have
double x = System.Math.Cos(u * UFactor);
double y = System.Math.Sin(u * UFactor);
double z = v * VFactor;
VResolution (inherited from Surface) Defines a Resolution for the v parameter Default is 20;

Public Instance Methods

Compile (inherited from Surface) Create a DisplayList in a MNDevice.
Copy (inherited from Surface) Makes a copy of the surface and returns it.
CreateDisplayList (inherited from Surface) Create a displayList like Compile, but it doesnt stores it to DisplayList
Equals (inherited from Object) 
getCross (inherited from Surface) This method calculates a crosspoint of a LineType with the surface, if this exists. In that case the crosspoint is given by the values u and v and can be calculated with the Value-function
GetHashCode (inherited from Object) 
GetType (inherited from Object) 
getULength Overrides getULength by returning ParamToLength
getVLength Overrides getVLength by returning v*Height.
Normal (inherited from Surface) Returns the normal at point u, v, which is calculated as th crossproduct of uDerivation and vDerivation.
ProjectPoint (inherited from Surface) Gets a point in the u,v parameter room, which is near to the giving Point after transforming with Value.
To2dCurve (inherited from Surface) Erzeugt zu einer 3D-Kurve eine Kurve im Parameterraum, sodass der Abbildung mit Value wieder die 3D-Kurve ergibt.
To3dCurve (inherited from Surface) Creates a 3D-Curve which belongs to the curve which is given by the ParamCurve transformed to the surface
ToString (inherited from Object) 
uDerivation Calculates the partial uDerivation
Value paramtisizes the class by adding (0,0,v) to Curve.Value(u)
vDerivation Calculates the partial vDerivation by returning constant (0,0,1)

Protected Instance Methods

Finalize (inherited from Object) 
getUResolution Overrides the getUResolution-method by resulting Resolution
getVResolution Overrides the getVResolution-method by resulting 1. If abs(Height) < 0.001 will be 1 returned.
MemberwiseClone (inherited from Object) 
setUResolution (inherited from Surface) Is the virtual set-function fo the property UResolution
setVResolution (inherited from Surface) Is the virtual set-function fo the property VResolution
