Detailed Description

Composites multiple images.

Date:

2000/12/10 20:08:22

Revision:

1.10

vtkCompositeFilter Takes a number of inputs of structured points with pixel data and z-buffer data, and composites them into one. The pixel data should be stored in point scalars, and the z buffer data should be stored in a point field called ZBuffer. This is the format produced by vtkRendererSource.

Notes:

Although this filter processes structured points, future plans are to have it produce vtkImageData and have it render select pieces of the image. Also, this filter ignores alpha (for now).

Member Function Documentation

vtkCompositeFilter* vtkCompositeFilter::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkStructuredPointsSource.

virtual const char* vtkCompositeFilter::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 vtkStructuredPointsToStructuredPointsFilter.

int vtkCompositeFilter::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 vtkStructuredPointsToStructuredPointsFilter.

virtual int vtkCompositeFilter::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 vtkStructuredPointsToStructuredPointsFilter.

vtkCompositeFilter* vtkCompositeFilter::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 vtkStructuredPointsToStructuredPointsFilter.

void vtkCompositeFilter::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.

void vtkCompositeFilter::AddInput (  vtkStructuredPoints *    )

Add a dataset to the list of data to append.

void vtkCompositeFilter::RemoveInput (  vtkStructuredPoints *    )

Remove a dataset from the list of data to append.

vtkStructuredPoints* vtkCompositeFilter::GetInput (  int    idx )

Get any input of this filter.

void vtkCompositeFilter::operator= (  const vtkCompositeFilter &    )  [inline, protected]

Definition at line 86 of file vtkCompositeFilter.h.

void vtkCompositeFilter::Execute (    )  [protected, virtual]

Reimplemented from vtkSource.

int vtkCompositeFilter::ComputeInputUpdateExtents (  vtkDataObject *    data )  [protected, virtual]

What is the input update extent that is required to produce the desired output? By default, the whole input is always required but this is overridden in many subclasses. Reimplemented from vtkSource.
