Detailed Description

Generate a superellipsoid.

vtkParametricSuperEllipsoid generates a superellipsoid. A superellipsoid is a versatile primitive that is controlled by two parameters n1 and n2. As special cases it can represent a sphere, square box, and closed cylindrical can.

For further information about this surface, please consult the technical description "Parametric surfaces" in http://www.vtk.org/documents.php in the "VTK Technical Documents" section in the VTk.org web pages.

Also see: http://paulbourke.net/geometry/superellipse/

Warning: Care needs to be taken specifying the bounds correctly. You may need to carefully adjust MinimumU, MinimumV, MaximumU, MaximumV.

Thanks:: Andrew Maclean andre.nosp@m.w.am.nosp@m.aclea.nosp@m.n@gm.nosp@m.ail.c.nosp@m.om for creating and contributing the class.

static

virtual int vtkParametricSuperEllipsoid::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkParametricFunction.

virtual vtkObjectBase* vtkParametricSuperEllipsoid::NewInstanceInternal ( ) const

void vtkParametricSuperEllipsoid::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkParametricFunction.

static vtkParametricSuperEllipsoid* vtkParametricSuperEllipsoid::New ( )

static

Construct a superellipsoid with the following parameters: MinimumU = 0, MaximumU = 2*Pi, MinimumV = 0, MaximumV = Pi, JoinU = 1, JoinV = 0, TwistU = 0, TwistV = 0, ClockwiseOrdering = 1, DerivativesAvailable = 0, N1 = 1, N2 = 1, XRadius = 1, YRadius = 1, ZRadius = 1, a sphere in this case.

virtual int vtkParametricSuperEllipsoid::GetDimension ( )

inlinevirtual

Return the parametric dimension of the class.

Implements vtkParametricFunction.

virtual

Set/Get the scaling factor for the x-axis. Default is 1.

virtual void vtkParametricSuperEllipsoid::SetYRadius ( double )

virtual

Set/Get the scaling factor for the y-axis. Default is 1.

virtual double vtkParametricSuperEllipsoid::GetYRadius ( )

virtual

Set/Get the scaling factor for the y-axis. Default is 1.

virtual void vtkParametricSuperEllipsoid::SetZRadius ( double )

virtual

Set/Get the scaling factor for the z-axis. Default is 1.

virtual double vtkParametricSuperEllipsoid::GetZRadius ( )

virtual

Set/Get the scaling factor for the z-axis. Default is 1.

virtual void vtkParametricSuperEllipsoid::SetN1 ( double )

virtual

Set/Get the "squareness" parameter in the z axis. Default is 1.

virtual double vtkParametricSuperEllipsoid::GetN1 ( )

Set/Get the "squareness" parameter in the x-y plane. Default is 1.

virtual double vtkParametricSuperEllipsoid::GetN2 ( )

virtual

Set/Get the "squareness" parameter in the x-y plane. Default is 1.

virtual void vtkParametricSuperEllipsoid::Evaluate	(	double	uvw[3],
		double	Pt[3],
		double	Duvw[9]
	)

virtual

A superellipsoid. This function performs the mapping $f(u,v) \rightarrow (x,y,x)$ , returning it as Pt. It also returns the partial derivatives Du and Dv. $Pt = (x, y, z), Du = (dx/du, dy/du, dz/du), Dv = (dx/dv, dy/dv, dz/dv)$ . Then the normal is $N = Du X Dv$ .

Implements vtkParametricFunction.

virtual double vtkParametricSuperEllipsoid::EvaluateScalar	(	double	uvw[3],
		double	Pt[3],
		double	Duvw[9]
	)

virtual

Calculate a user defined scalar using one or all of uvw, Pt, Duvw. uvw are the parameters with Pt being the the cartesian point, Duvw are the derivatives of this point with respect to u, v and w. Pt, Duvw are obtained from Evaluate(). This function is only called if the ScalarMode has the value vtkParametricFunctionSource::SCALAR_FUNCTION_DEFINED If the user does not need to calculate a scalar, then the instantiated function should return zero.

Implements vtkParametricFunction.
