Detailed Description

Generate conic spiral surfaces that resemble sea-shells.

vtkParametricConicSpiral generates conic spiral surfaces. These can resemble sea shells, or may look like a torus "eating" its own tail.

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.

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.

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.

void vtkParametricConicSpiral::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 vtkObject.

static vtkParametricConicSpiral* vtkParametricConicSpiral::New ( )

static

Construct a conic spiral surface with the following parameters: MinimumU = 0, MaximumU = 2Pi, MinimumV = 0, MaximumV = 2Pi, JoinU = 0, JoinV = 0, TwistU = 0, TwistV = 0, ClockwiseOrdering = 1, DerivativesAvailable = 1, A = 0.2, B = 1.0, C = 0.1, N = 2.

virtual int vtkParametricConicSpiral::GetDimension ( )

inlinevirtual

Return the parametric dimension of the class.

Implements vtkParametricFunction.

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

virtual

A conic spiral surface. 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 vtkParametricConicSpiral::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.
