Public Instance Constructors

Sphere Constructor Constructor without parameter. I initialize UFactor with 2*PI and VFactor with PI.

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
Radius retrieves or writes the radius of the sphere
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 Overrides the method getCross and implements a method for get the crosspoint with a Line L, which is nearer to L.Q.
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 Return the normalvector of a sphere
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 sphere for the to parameters u and v which are given in the interval [0, 1]
vDerivation Calculates the partial vDerivation
