Detailed Description

a specific level-of-detail strategy using the quadric clustering decimation algorithm

vtkQuadricLODActor implements a specific strategy for level-of-detail using the vtkQuadricClustering decimation algorithm. It supports only two levels of detail: full resolution and a decimated version. The decimated LOD is generated using a tuned strategy to produce output consistent with the requested interactive frame rate (i.e., the vtkRenderWindowInteractor's DesiredUpdateRate). It also makes use of display lists for performance, and adjusts the vtkQuadricClustering algorithm to take into account the dimensionality of the data (e.g., 2D, x-y surfaces may be binned into n x n x 1 to reduce extra polygons in the z-direction). Finally, the filter may optionally be set in "Static" mode (this works with the vtkMapper::SetStatic() method). `Enabling Static results in a one time execution of the Mapper's pipeline. After that, the pipeline no longer updated (unless manually forced to do so).

Warning
By default the algorithm is set up to pre-compute the LODs. That is, on the first render (whether a full resolution render or interactive render) the LOD is computed. This behavior can be changed so that the LOD construction is deferred until the first interactive render. Either way, when the LOD is constructed, the user may notice a short pause.
This class can be used as a direct replacement for vtkActor. It may also be used as a replacement for vtkFollower's (the ability to track a camera is provided).

virtual void vtkQuadricLODActor::SetStatic ( int  )
virtual

Turn on/off a flag to control whether the underlying pipeline is static. If static, this means that the data pipeline executes once and then not again until the user manually modifies this class. By default, Static is off because trying to debug this is tricky, and you should only use it when you know what you are doing.

virtual void vtkQuadricLODActor::SetDataConfiguration ( int  )
virtual

Force the binning of the quadric clustering according to application knowledge relative to the dimension of the data. For example, if you know your data lies in a 2D x-y plane, the performance of the quadric clustering algorithm can be greatly improved by indicating this (i.e., the number of resulting triangles, and the quality of the decimation version is better). Setting this parameter forces the binning to be configured consistent with the dimnesionality of the data, and the collapse dimension ratio is ignored. Specifying the value of DataConfiguration to UNKNOWN (the default value) means that the class will attempt to figure the dimension of the class automatically using the CollapseDimensionRatio ivar.

virtual void vtkQuadricLODActor::SetCollapseDimensionRatio ( double  )
virtual

If the data configuration is set to UNKNOWN, this class attempts to figure out the dimensionality of the data using CollapseDimensionRatio. This ivar is the ratio of short edge of the input bounding box to its long edge, which is then used to collapse the data dimension (and set the quadric bin size in that direction to one). By default, this value is 0.05.

If the data configuration is set to UNKNOWN, this class attempts to figure out the dimensionality of the data using CollapseDimensionRatio. This ivar is the ratio of short edge of the input bounding box to its long edge, which is then used to collapse the data dimension (and set the quadric bin size in that direction to one). By default, this value is 0.05.

virtual void vtkQuadricLODActor::SetMaximumDisplayListSize ( int  )
virtual

Specify the maximum display list size. This variable is used to determine whether to use display lists (ImmediateModeRenderingOff) or not. Controlling display list size is important to prevent program crashes (i.e., overly large display lists on some graphics hardware will cause faults). The display list size is the length of the vtkCellArray representing the topology of the input vtkPolyData.

Specify the maximum display list size. This variable is used to determine whether to use display lists (ImmediateModeRenderingOff) or not.

virtual

Set/Get the camera to follow. This method is only applicable when the prop type is set to a vtkFollower.

virtual void vtkQuadricLODActor::Render ( vtkRenderer ,

This causes the actor to be rendered. Depending on the frame rate request, it will use either a full resolution render or an interactive render (i.e., it will use the decimated geometry).

Reimplemented from vtkActor.

This method is used internally by the rendering process. We overide the superclass method to properly set the estimated render time.
