Cone overview

Public Instance Constructors

Cone Constructor Constuructor without parameters. It sets the UPeriodicity and the UFactor to 2PI.

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.
DisplayList (inherited from Surface) Holds a displaylist, which was generated by Compile
HalfAngle Gets or sets the half angle on the top.
Height Sets or gets the height of the cone by setting the VFactor
Radius Sets or gets the base radius of the cone.
TextureOffset (inherited from Surface) Sets or gets an offset for a texture
TopRadius Gets and sets the top radius of a cone. If Radius and top radius are the same you get a cylinder.
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 (inherited from Surface) Calculates the real length on the surface for an u, when v=const.
getVLength (inherited from Surface) Calculates the real length on the surface for an v, when u=const.
Normal (inherited from Surface) Returns the normal at point u, v, which is calculated as th crossproduct of uDerivation and vDerivation.
ProjectPoint Overrides this method and calculates a point on the cone in u, v parameters. This point is nearest to the given Point.
To2dCurve (inherited from Surface) Erzeugt zu einer 3D-Kurve eine Kurve im Parameterraum, sodass der Abbildung mit Value wieder die 3D-Kurve ergibt.
To3dCurve Is only implemented, if the paramcurve is a 2D - Line. In case that this line is parallel to the x-axis a Circle3d will be returned, which belongs to the paramcurve. If it is parallel to y-axis a Line3d on the Cone, which belongs to the paramcurve will be returned
ToString (inherited from Object) 
uDerivation Overrides the uDerivation function and implements the cone calulations.
Value Overrides the Value function and implements the cone calulations.
vDerivation Overrides the vDerivation function and implements the cone calulations.

Protected Instance Methods

getUResolution (inherited from Surface) Is the virtual getfunction fo the property UResolution
getVResolution (inherited from Surface) Is the virtual getfunction fo the property VResolution
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
