Detailed Description

create oriented ribbons from lines defined in polygonal dataset

vtkRibbonFilter is a filter to create oriented ribbons from lines defined in polygonal dataset. The orientation of the ribbon is along the line segments and perpendicular to "projected" line normals. Projected line normals are the original line normals projected to be perpendicular to the local line segment. An offset angle can be specified to rotate the ribbon with respect to the normal.

Warning:
The input line must not have duplicate points, or normals at points that are parallel to the incoming/outgoing line segments. (Duplicate points can be removed with vtkCleanPolyData.) If a line does not meet this criteria, then that line is not tubed.

Member Function Documentation

virtual const char* vtkRibbonFilter::GetClassName (  )  [virtual]

Reimplemented from vtkPolyDataAlgorithm.

static int vtkRibbonFilter::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 vtkPolyDataAlgorithm.

virtual int vtkRibbonFilter::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 vtkPolyDataAlgorithm.

static vtkRibbonFilter* vtkRibbonFilter::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkPolyDataAlgorithm.

void vtkRibbonFilter::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 vtkPolyDataAlgorithm.

static vtkRibbonFilter* vtkRibbonFilter::New (  )  [static]

Construct ribbon so that width is 0.1, the width does not vary with scalar values, and the width factor is 2.0.

Reimplemented from vtkPolyDataAlgorithm.

virtual void vtkRibbonFilter::SetWidth ( double   )  [virtual]

Set the "half" width of the ribbon. If the width is allowed to vary, this is the minimum width. The default is 0.5

virtual double vtkRibbonFilter::GetWidth (  )  [virtual]

Set the "half" width of the ribbon. If the width is allowed to vary, this is the minimum width. The default is 0.5

virtual void vtkRibbonFilter::SetAngle ( double   )  [virtual]

Set the offset angle of the ribbon from the line normal. (The angle is expressed in degrees.) The default is 0.0

virtual double vtkRibbonFilter::GetAngle (  )  [virtual]

Set the offset angle of the ribbon from the line normal. (The angle is expressed in degrees.) The default is 0.0
