Detailed Description

vtkSimpleCellTessellator - helper class to perform cell tessellation

Description vtkSimpleCellTessellator is a helper class to perform adaptive tessellation of particular cell topologies. The major purpose for this class is to transform higher-order cell types (e.g., higher-order finite elements) into linear cells that can then be easily visualized by VTK. This class works in conjunction with the vtkGenericDataSet and vtkGenericAdaptorCell classes.

This algorithm is based on edge subdivision. An error metric along each edge is evaluated, and if the error is greater than some tolerance, the edge is subdivided (as well as all connected 2D and 3D cells). The process repeats until the error metric is satisfied. Since the algorithm is based on edge subdivision it inherently avoid T-junctions.

A significant issue addressed by this algorithm is to insure face compatibility across neigboring cells. That is, diagonals due to face triangulation must match to insure that the mesh is compatible. The algorithm employs a precomputed table to accelerate the tessellation process. The table was generated with the help of vtkOrderedTriangulator the basic idea is that the choice of diagonal is made only by considering the relative value of the point ids.

override void Kitware.VTK.vtkSimpleCellTessellator.Dispose ( bool disposing )

protected

Automatically generated protected Dispose method - called from public Dispose or the C# destructor. DO NOT call directly.

Reimplemented from Kitware.VTK.vtkGenericCellTessellator.

int Kitware.VTK.vtkSimpleCellTessellator.GetFixedSubdivisions ( )

Return the number of fixed subdivisions. It is used to prevent from infinite loop in degenerated cases. For order 3 or higher, if the inflection point is exactly on the mid-point, error metric will not detect that a subdivision is required. 0 means no fixed subdivision: there will be only adaptive subdivisions.

The algorithm first performs GetFixedSubdivisions' non adaptive subdivisions followed by at mostGetMaxAdaptiveSubdivisions' adaptive subdivisions. Hence, there are at most `GetMaxSubdivisionLevel' subdivisions.

Postcondition:: positive_result: result>=0 && result<=GetMaxSubdivisionLevel()

virtual vtkGenericAdaptorCell Kitware.VTK.vtkSimpleCellTessellator.GetGenericCell ( )

virtual

Postcondition:: valid_result: result==GetMaxSubdivisionLevel()-GetFixedSubdivisions()

int Kitware.VTK.vtkSimpleCellTessellator.GetMaxSubdivisionLevel ( )

Return the maximum level of subdivision. It is used to prevent from infinite loop in degenerated cases. For order 3 or higher, if the inflection point is exactly on the mid-point, error metric will not detect that a subdivision is required. 0 means no subdivision, neither fixed nor adaptive.
