Detailed Description

an actor that supports multiple levels of detail

vtkLODActor is an actor that stores multiple levels of detail (LOD) and can automatically switch between them. It selects which level of detail to use based on how much time it has been allocated to render. Currently a very simple method of TotalTime/NumberOfActors is used. (In the future this should be modified to dynamically allocate the rendering time between different actors based on their needs.)

There are three levels of detail by default. The top level is just the normal data. The lowest level of detail is a simple bounding box outline of the actor. The middle level of detail is a point cloud of a fixed number of points that have been randomly sampled from the mapper's input data. Point attributes are copied over to the point cloud. These two lower levels of detail are accomplished by creating instances of a vtkOutlineFilter (low-res) and vtkMaskPoints (medium-res). Additional levels of detail can be add using the AddLODMapper() method.

To control the frame rate, you typically set the vtkRenderWindowInteractor DesiredUpdateRate and StillUpdateRate. This then will cause vtkLODActor to adjust its LOD to fulfill the requested update rate.

For greater control on levels of detail, see also vtkLODProp3D. That class allows arbitrary definition of each LOD.

Warning
If you provide your own mappers, you are responsible for setting its ivars correctly, such as ScalarRange, LookupTable, and so on.
On some systems the point cloud rendering (the default, medium level of detail) can result in points so small that they can hardly be seen. In this case, use the GetProperty()->SetPointSize() method to increase the rendered size of the points.

Creates a vtkLODActor with the following defaults: origin(0,0,0) position=(0,0,0) scale=(1,1,1) visibility=1 pickable=1 dragable=1 orientation=(0,0,0).

NumberOfCloudPoints is set to 150.

void vtkLODActor::Render ( vtkRenderer ,
vtkMapper  
)
overridevirtual

This causes the actor to be rendered.

It, in turn, will render the actor's property and then mapper.

Reimplemented from vtkActor.

int vtkLODActor::RenderOpaqueGeometry ( vtkViewport viewport)
overridevirtual

This method is used internally by the rendering process.

We override the superclass method to properly set the estimated render time.

Reimplemented from vtkActor.

void vtkLODActor::ReleaseGraphicsResources ( vtkWindow )
overridevirtual

Release any graphics resources that are being consumed by this actor.

The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkActor.

void vtkLODActor::AddLODMapper ( vtkMapper mapper)

Add another level of detail.

They do not have to be in any order of complexity.

virtual void vtkLODActor::SetLowResFilter ( vtkPolyDataAlgorithm )
virtual

You may plug in your own filters to decimate/subsample the input.

The default is to use a vtkOutlineFilter (low-res) and vtkMaskPoints (medium-res).

virtual void vtkLODActor::SetMediumResFilter ( vtkPolyDataAlgorithm )
virtual

You may plug in your own filters to decimate/subsample the input.

The default is to use a vtkOutlineFilter (low-res) and vtkMaskPoints (medium-res).

virtual vtkPolyDataAlgorithm* vtkLODActor::GetLowResFilter ( )
virtual

You may plug in your own filters to decimate/subsample the input.

The default is to use a vtkOutlineFilter (low-res) and vtkMaskPoints (medium-res).

virtual vtkPolyDataAlgorithm* vtkLODActor::GetMediumResFilter ( )
virtual

You may plug in your own filters to decimate/subsample the input.

The default is to use a vtkOutlineFilter (low-res) and vtkMaskPoints (medium-res).

virtual int vtkLODActor::GetNumberOfCloudPoints ( )
virtual

Set/Get the number of random points for the point cloud.

virtual void vtkLODActor::SetNumberOfCloudPoints ( int  )
virtual

Set/Get the number of random points for the point cloud.

virtual vtkMapperCollection* vtkLODActor::GetLODMappers ( )
virtual

All the mappers for different LODs are stored here.

The order is not important.

void vtkLODActor::Modified ( )
overridevirtual

When this objects gets modified, this method also modifies the object.

Reimplemented from vtkObject.

void vtkLODActor::ShallowCopy ( vtkProp prop)
overridevirtual

Shallow copy of an LOD actor.

Overloads the virtual vtkProp method.

Reimplemented from vtkActor.

protectedvirtual
virtual void vtkLODActor::UpdateOwnLODs ( )
