Detailed Description

Contour interpolator for polygonal data.

vtkPolyDataContourLineInterpolator is an abstract base class for contour line interpolators that interpolate on polygonal data.

◆ IsA()

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 vtkContourLineInterpolator.

Reimplemented in vtkPolygonalSurfaceContourLineInterpolator.

◆ PrintSelf()

void vtkPolyDataContourLineInterpolator::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

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 vtkContourLineInterpolator.

Reimplemented in vtkPolygonalSurfaceContourLineInterpolator.

◆ InterpolateLine()

int vtkPolyDataContourLineInterpolator::InterpolateLine ( vtkRenderer ren,
vtkContourRepresentation rep,
int  idx1,
int  idx2 
)
overridepure virtual

Subclasses that wish to interpolate a line segment must implement this.

For instance vtkBezierContourLineInterpolator adds nodes between idx1 and idx2, that allow the contour to adhere to a bezier curve.

Implements vtkContourLineInterpolator.

Implemented in vtkPolygonalSurfaceContourLineInterpolator.

◆ UpdateNode()

int vtkPolyDataContourLineInterpolator::UpdateNode ( vtkRenderer ,
vtkContourRepresentation ,
double vtkNotUsednode,
int   vtkNotUsedidx 
)
overridepure virtual

The interpolator is given a chance to update the node.

vtkImageContourLineInterpolator updates the idx'th node in the contour, so it automatically sticks to edges in the vicinity as the user constructs the contour. Returns 0 if the node (world position) is unchanged.

Reimplemented from vtkContourLineInterpolator.

Implemented in vtkPolygonalSurfaceContourLineInterpolator.

◆ GetPolys()

Be sure to add polydata on which you wish to place points to this list or they will not be considered for placement.
