| virtual const char* vtkParametricMobius::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkParametricFunction.
| 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 vtkTypeRevisionMacro 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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkParametricFunction.
| static vtkParametricMobius* vtkParametricMobius::SafeDownCast | ( | vtkObject * | o | ) | [static] |
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.

| 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.
