This class is a simple algorithm that takes a single starting simplex -- a tetrahedron, triangle, or line segment -- and calls a function you pass it with (possibly many times) tetrahedra, triangles, or lines adaptively sampled from the one you specified. It uses an algorithm you specify to control the level of adaptivity.
This class does not create vtkUnstructuredGrid output because it is intended for use in mappers as well as filters. Instead, it calls the registered function with simplices as they are created.
The subdivision algorithm should change the vertex coordinates (it must change both geometric and, if desired, parametric coordinates) of the midpoint. These coordinates need not be changed unless the EvaluateEdge() member returns true. The vtkStreamingTessellator itself has no way of creating a more accurate midpoint vertex.
Here's how to use this class:
vtkStreamingTessellator to interpolate field values at newly created vertices. Interpolated field values are stored just beyond the parametric coordinates associated with a vertex. They will always be double values; it does not make sense to interpolate a boolean or string value and your output and subdivision subroutines may always cast to a float or use floor() to truncate an interpolated value to an integer.

Reset/access the histogram of subdivision cases encountered. The histogram may be used to examine coverage during testing as well as characterizing the tessellation algorithm's performance. You should call ResetCounts() once, at the beginning of a stream of tetrahedra. It must be called before AdaptivelySample3Facet() to prevent uninitialized memory reads. These functions have no effect (and return 0) when PARAVIEW_DEBUG_TESSELLATOR has not been defined. By default, PARAVIEW_DEBUG_TESSELLATOR is not defined, and your code will be fast and efficient. Really! |
