Detailed Description

subdivide triangles based on edge and/or area metrics

vtkAdaptiveSubdivisionFilter is a filter that subdivides triangles based on maximum edge length and/or triangle area. It uses a simple case-based, multi-pass approach to repeatedly subdivide the input triangle mesh to meet the area and/or edge length criteria. New points may be inserted only on edges; depending on the number of edges to be subdivided a different number of triangles are inserted ranging from two (i.e., two triangles replace the original one) to four.

Triangle subdivision is controlled by specifying a maximum edge length and/or triangle area that any given triangle may have. Subdivision proceeds until their criteria are satisfied. Note that using excessively small criteria values can produce enormous meshes with the possibility of exhausting system memory. Also, if you want to ignore a particular criterion value (e.g., triangle area) then simply set the criterion value to a very large value (e.g., VTK_DOUBLE_MAX).

An incremental point locator is used because as new points are created, a search is made to ensure that a point has not already been created. This ensures that the mesh remains compatible (watertight) as long as certain criteria are not used (triangle area limit, and number of triangles limit).

To prevent overly large triangle meshes from being created, it is possible to set a limit on the number of triangles created. By default this number is a very large number (i.e., no limit). Further, a limit on the number of passes can also be set, this is mostly useful to generated animations of the algorithm.

Finally, the attribute data (point and cell data) is treated as follows. The cell data from a parent triangle is assigned to its subdivided children. Point data is interpolated along edges as the edges are subdivided.

Warning
The subdivision is linear along edges. Thus do not expect smoothing or blending effects to occur. If you need to smooth the resulting mesh use an algorithm like vtkWindowedSincPolyDataFilter or vtkSmoothPolyDataFilter.

The filter retains mesh compatibility (watertightness) if the mesh was originally compatible; and the area, max triangles criteria are not used.

Warning
The filter requires a triangle mesh. Use vtkTriangleFilter to tessellate the mesh if necessary.

virtual void vtkAdaptiveSubdivisionFilter::SetMaximumEdgeLength ( double  )
virtual

Specify the maximum edge length that a triangle may have.

Edges longer than this value are split in half and the associated triangles are modified accordingly.

virtual double vtkAdaptiveSubdivisionFilter::GetMaximumEdgeLength ( )
virtual

Specify the maximum edge length that a triangle may have.

Edges longer than this value are split in half and the associated triangles are modified accordingly.

virtual void vtkAdaptiveSubdivisionFilter::SetMaximumTriangleArea ( double  )
virtual

Specify the maximum area that a triangle may have.

Triangles larger than this value are subdivided to meet this threshold. Note that if this criterion is used it may produce non-watertight meshes as a result.

virtual double vtkAdaptiveSubdivisionFilter::GetMaximumTriangleArea ( )
virtual

Specify the maximum area that a triangle may have.

Triangles larger than this value are subdivided to meet this threshold. Note that if this criterion is used it may produce non-watertight meshes as a result.

virtual void vtkAdaptiveSubdivisionFilter::SetMaximumNumberOfTriangles ( vtkIdType  )
virtual

Set a limit on the maximum number of triangles that can be created.

If the limit is hit, it may result in premature termination of the algorithm and the results may be less than satisfactory (for example non-watertight meshes may be created). By default, the limit is set to a very large number (i.e., no effective limit).

virtual vtkIdType vtkAdaptiveSubdivisionFilter::GetMaximumNumberOfTriangles ( )
virtual

Set a limit on the maximum number of triangles that can be created.

If the limit is hit, it may result in premature termination of the algorithm and the results may be less than satisfactory (for example non-watertight meshes may be created). By default, the limit is set to a very large number (i.e., no effective limit).

virtual void vtkAdaptiveSubdivisionFilter::SetMaximumNumberOfPasses ( vtkIdType  )
virtual

Set a limit on the number of passes (i.e., levels of subdivision).

If the limit is hit, then the subdivision process stops and additional passes (needed to meet other criteria) are aborted. The default limit is set to a very large number (i.e., no effective limit).

virtual vtkIdType vtkAdaptiveSubdivisionFilter::GetMaximumNumberOfPasses ( )
virtual

Set a limit on the number of passes (i.e., levels of subdivision).

If the limit is hit, then the subdivision process stops and additional passes (needed to meet other criteria) are aborted. The default limit is set to a very large number (i.e., no effective limit).

void vtkAdaptiveSubdivisionFilter::SetLocator ( vtkIncrementalPointLocator locator)

Set / get a spatial locator for merging points.

By default, an instance of vtkMergePoints is used. This is used to merge coincident points during subdivision.

virtual vtkIncrementalPointLocator* vtkAdaptiveSubdivisionFilter::GetLocator ( )
virtual

Set / get a spatial locator for merging points.

By default, an instance of vtkMergePoints is used. This is used to merge coincident points during subdivision.

virtual void vtkAdaptiveSubdivisionFilter::SetOutputPointsPrecision ( int  )
virtual

Set/get the desired precision for the output types.

See the documentation for the vtkAlgorithm::Precision enum for an explanation of the available precision settings.

virtual int vtkAdaptiveSubdivisionFilter::GetOutputPointsPrecision ( )

void vtkAdaptiveSubdivisionFilter::CreateDefaultLocator ( )

Create a default locator.

Used to create one when none is specified.

vtkMTimeType vtkAdaptiveSubdivisionFilter::GetMTime ( )
