Detailed Description

An object to composite multiple render windows.

Date:

2001/10/31 16:36:11

Revision:

1.2

vtkCompositeManager 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. Subclass implementation may not handle transparency well.

Attention:

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

virtual const char* vtkCompositeManager::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. Reimplemented in vtkTreeComposite.

int vtkCompositeManager::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. Reimplemented in vtkTreeComposite.

virtual int vtkCompositeManager::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. Reimplemented in vtkTreeComposite.

vtkCompositeManager* vtkCompositeManager::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. Reimplemented in vtkTreeComposite.

void vtkCompositeManager::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. Reimplemented in vtkTreeComposite.

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

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

void vtkCompositeManager::SetRenderWindow (  vtkRenderWindow *    renWin )

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

void vtkCompositeManager::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 vtkCompositeManager::InitializeOffScreen (    )

turn off screen rendering on for the

void vtkCompositeManager::StartInteractor (    )

Callbacks that initialize and finish the compositing.

void vtkCompositeManager::ExitInteractor (    )

Callbacks that initialize and finish the compositing.

void vtkCompositeManager::StartRender (    )

Callbacks that initialize and finish the compositing.

void vtkCompositeManager::EndRender (    )

Callbacks that initialize and finish the compositing.

void vtkCompositeManager::RenderRMI (    )

Callbacks that initialize and finish the compositing.

void vtkCompositeManager::ResetCamera (  vtkRenderer *    ren )

Callbacks that initialize and finish the compositing.

void vtkCompositeManager::ResetCameraClippingRange (  vtkRenderer *    ren )

Callbacks that initialize and finish the compositing.

void vtkCompositeManager::ComputeVisiblePropBoundsRMI (    )

Callbacks that initialize and finish the compositing.

void vtkCompositeManager::InitializeRMIs (    )

If the user wants to handle the event loop, then they must call this method to initialize the RMIs.

void vtkCompositeManager::SetReductionFactor (  int    factor )

The reduction facor makes the transfered images smaller to decrease the render time. The final image is pixel replicated to be the original size. This option can be used by an interactor style to help get desired frame rates. The factor only needs to be set on process 0. Call SetRenderWindow before calling SetReductionFactor.

virtual int vtkCompositeManager::GetReductionFactor (    )  [virtual]

The reduction facor makes the transfered images smaller to decrease the render time. The final image is pixel replicated to be the original size. This option can be used by an interactor style to help get desired frame rates. The factor only needs to be set on process 0. Call SetRenderWindow before calling SetReductionFactor.

virtual void vtkCompositeManager::SetUseChar (  int    )  [virtual]

This flag tells the compositer to use char values for pixel data rather than float. Default is float. I have seen some artifacts on some systems with char.

virtual int vtkCompositeManager::GetUseChar (    )  [virtual]

This flag tells the compositer to use char values for pixel data rather than float. Default is float. I have seen some artifacts on some systems with char.

virtual void vtkCompositeManager::UseCharOn (    )  [virtual]

This flag tells the compositer to use char values for pixel data rather than float. Default is float. I have seen some artifacts on some systems with char.

virtual void vtkCompositeManager::UseCharOff (    )  [virtual]

This flag tells the compositer to use char values for pixel data rather than float. Default is float. I have seen some artifacts on some systems with char.

virtual void vtkCompositeManager::SetUseCompositing (  int    )  [virtual]

This flag turns the compositer on or off.

virtual int vtkCompositeManager::GetUseCompositing (    )  [virtual]

This flag turns the compositer on or off.

virtual void vtkCompositeManager::UseCompositingOn (    )  [virtual]

This flag turns the compositer on or off.

virtual void vtkCompositeManager::UseCompositingOff (    )  [virtual]

This flag turns the compositer on or off.

virtual double vtkCompositeManager::GetGetBuffersTime (    )  [virtual]

Get the times to set/get the buffers, Composite, and the time it takes all processes to finish the rendering step.

virtual double vtkCompositeManager::GetSetBuffersTime (    )  [virtual]

Get the times to set/get the buffers, Composite, and the time it takes all processes to finish the rendering step.

virtual double vtkCompositeManager::GetCompositeTime (    )  [virtual]

Get the times to set/get the buffers, Composite, and the time it takes all processes to finish the rendering step.

virtual double vtkCompositeManager::GetMaxRenderTime (    )  [virtual]

Get the times to set/get the buffers, Composite, and the time it takes all processes to finish the rendering step.

float vtkCompositeManager::GetZ (  int    x, int    y )

Get the value of the z buffer at a position.

virtual void vtkCompositeManager::SetController (  vtkMultiProcessController *    )  [virtual]

Set/Get the controller use in compositing (set to the global controller by default) If not using the default, this must be called before any other methods.

virtual vtkMultiProcessController* vtkCompositeManager::GetController (    )  [virtual]

Set/Get the controller use in compositing (set to the global controller by default) If not using the default, this must be called before any other methods.
