Detailed Description

approximate nonlinear FEM elements with simplices

$Date$ $Revision$

This class approximates nonlinear FEM elements with linear simplices.

Warning: This class is temporary and will go away at some point after ParaView 1.4.0.

This filter rifles through all the cells in an input vtkDataSet. It tesselates each cell and uses the vtkStreamingTessellator and vtkDataSetEdgeSubdivisionCriterion classes to generate simplices that approximate the nonlinear mesh using some approximation metric (encoded in the particular vtkDataSetEdgeSubdivisionCriterion::EvaluateEdge implementation). The simplices are placed into the filter's output vtkDataSet object by the callback routines AddATetrahedron, AddATriangle, and AddALine, which are registered with the triangulator.

The output mesh will have geometry and any fields specified as attributes in the input mesh's point data. The attribute's copy flags are honored, except for normals.

Internals:

The filter's main member function is RequestData(). This function first calls SetupOutput() which allocates arrays and some temporary variables for the primitive callbacks (OutputTriangle and OutputLine which are called by AddATriangle and AddALine, respectively). Each cell is given an initial tesselation, which results in one or more calls to OutputTetrahedron, OutputTriangle or OutputLine to add elements to the OutputMesh. Finally, Teardown() is called to free the filter's working space.
