Detailed Description

Generate a Mobius strip.

vtkParametricMobius generates a Mobius strip.

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:

Member Function Documentation

static int vtkParametricMobius::IsTypeOf

(

const char *

name

)

[static]

Return 1 if this class type 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 int vtkParametricMobius::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.

static vtkParametricMobius* vtkParametricMobius::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkParametricFunction.

virtual vtkObjectBase* vtkParametricMobius::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkParametricFunction.

vtkParametricMobius* vtkParametricMobius::NewInstance

(

)

const

Reimplemented from vtkParametricFunction.

void vtkParametricMobius::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 vtkParametricMobius* vtkParametricMobius::New

(

)

[static]

Construct a Mobius strip with the following parameters: MinimumU = 0, MaximumU = 2*Pi, MinimumV = -1, MaximumV = 1, JoinU = 1, JoinV = 0, TwistU = 0, TwistV = 0, ClockwiseOrdering = 1, DerivativesAvailable = 1, Radius = 1.

Reimplemented from vtkObject.

virtual void vtkParametricMobius::SetRadius

(

double

)

[virtual]

Set/Get the radius of the Mobius strip.

virtual double vtkParametricMobius::GetRadius

(

)

[virtual]

Set/Get the radius of the Mobius strip.

virtual int vtkParametricMobius::GetDimension

(

)

[inline, virtual]

Return the parametric dimension of the class.

Implements vtkParametricFunction.

Definition at line 58 of file vtkParametricMobius.h.

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

The Mobius strip. This function performs the mapping , returning it as Pt. It also returns the partial derivatives Du and Dv. . Then the normal is .

Implements vtkParametricFunction.

virtual double vtkParametricMobius::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, Du, Dv 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.
