Detailed Description

An object to composite multiple render windows.

Date:

2000/12/11 14:09:54

Revision:

1.7

vtkTreeComposite operates in multiple processes. Each compositer has a render window. They use vtkMultiProcessControllers to comunicate the color and depth buffer to process 0's render window. It will not handle transparency well.

note:

You should set up the renders and render window interactor before setting the compositers render window. We set up observers on the renderer, An have no easy way of knowing when the renderers change. We could create AddRenderer and RemoveRenderer events ...

Member Function Documentation

vtkTreeComposite* vtkTreeComposite::New (    )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

virtual const char* vtkTreeComposite::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 vtkObject.

int vtkTreeComposite::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 vtkObject.

virtual int vtkTreeComposite::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 vtkObject.

vtkTreeComposite* vtkTreeComposite::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 vtkObject.

void vtkTreeComposite::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 vtkObject.

virtual vtkRenderWindow* vtkTreeComposite::GetRenderWindow (    )  [virtual]

Set/Get the RenderWindow to use for compositing. We add a start and end observer to the window.

void vtkTreeComposite::SetRenderWindow (  vtkRenderWindow *    renWin )

void vtkTreeComposite::InitializePieces (    )

This method sets the piece and number of pieces for each actor with a polydata mapper. My other option is to do it every render, but that would force a partioning scheme.

void vtkTreeComposite::InitializeOffScreen (    )

turn off screen rendering on for the

void vtkTreeComposite::StartInteractor (    )

Callbacks that initialize and finish the compositing.

void vtkTreeComposite::ExitInteractor (    )

void vtkTreeComposite::StartRender (    )

void vtkTreeComposite::EndRender (    )

void vtkTreeComposite::RenderRMI (    )

void vtkTreeComposite::ResetCamera (  vtkRenderer *    ren )

void vtkTreeComposite::ResetCameraClippingRange (  vtkRenderer *    ren )

void vtkTreeComposite::ComputeVisiblePropBoundsRMI (    )

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

Definition at line 131 of file vtkTreeComposite.h.

void vtkTreeComposite::Composite (  int    flag )  [protected]

void vtkTreeComposite::SetRenderWindowInteractor (  vtkRenderWindowInteractor *    iren )  [protected]

void vtkTreeComposite::ComputeVisiblePropBounds (  vtkRenderer *    ren, float    bounds[6] )  [protected]
