Detailed Description

plot data along an arbitrary polyline.

Date:
2000/12/10 20:08:22
Revision:
1.2

vtkArcPlotter performs plotting of attribute data along polylines defined with an input vtkPolyData data object. Any type of attribute data can be plotted including scalars, vectors, tensors, normals, texture coordinates, and field data. Either one or multiple data components can be plotted.

To use this class you must specify an input data set that contains one or more polylines, and some attribute data including which component of the attribute data. (By default, this class processes the first component of scalar data.) You will also need to set an offset radius (the distance of the polyline to the median line of the plot), a width for the plot (the distance that the minimum and maximum plot values are mapped into), an possibly an offset (used to offset attribute data with multiple components).

Normally the filter automatically computes normals for generating the offset arc plot. However, you can specify a default normal and use that instead.

Member Function Documentation

virtual const char* vtkArcPlotter::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataToPolyDataFilter.

unsigned long vtkArcPlotter::GetMTime   [virtual]
 

New GetMTime because of camera dependency.

Reimplemented from vtkObject.

virtual int vtkArcPlotter::IsA const char *    type [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 vtkPolyDataToPolyDataFilter.

int vtkArcPlotter::IsTypeOf const char *    type [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 vtkPolyDataToPolyDataFilter.

vtkArcPlotter* vtkArcPlotter::New   [inline, static]
 

Instantiate with no default camera and plot mode set to VTK_SCALARS.

Reimplemented from vtkPolyDataSource.

void vtkArcPlotter::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 vtkSource.

vtkArcPlotter* vtkArcPlotter::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataToPolyDataFilter.

virtual void vtkArcPlotter::SetCamera vtkCamera   [virtual]
 

Specify a camera used to orient the plot along the arc. If no camera is specified, then the orientation of the plot is arbitrary.

virtual void vtkArcPlotter::SetDefaultNormal float   ,
float   ,
float   
[virtual]
 

Set the default normal to use if you do not wish automatic normal calculation. The arc plot will be generated using this normal.

virtual void vtkArcPlotter::SetFieldDataArray int    [virtual]
 

Set/Get the field data array to plot. This instance variable is only applicable if field data is plotted.

virtual void vtkArcPlotter::SetHeight float    [virtual]
 

Set the height of the plot. (The radius combined with the height define the location of the plot relative to the generating polyline.)

virtual void vtkArcPlotter::SetOffset float    [virtual]
 

Specify an offset that translates each subsequent plot (if there is more than one component plotted) from the defining arc (i.e., polyline).

virtual void vtkArcPlotter::SetPlotComponent int    [virtual]
 

Set/Get the component number to plot if the data has more than one component. If the value of the plot component is == (-1), then all the components will be plotted.

virtual void vtkArcPlotter::SetPlotMode int    [virtual]
 

Specify which data to plot: scalars, vectors, normals, texture coords, tensors, or field data. If the data has more than one component, use the method SetPlotComponent to control which component to plot.

virtual void vtkArcPlotter::SetRadius float    [virtual]
 

Set the radius of the "median" value of the first plotted component.

virtual void vtkArcPlotter::SetUseDefaultNormal int    [virtual]
 

Set a boolean to control whether to use default normals. By default, normals are automatically computed from the generating polyline and camera.
