Detailed Description

fast generation of isosurface from 3D linear cells

vtkContour3DLinearGrid is a specialized filter that generates isocontours from an input vtkUnstructuredGrid consisting of 3D linear cells: tetrahedra, hexahedra, voxels, pyramids, and/or wedges. (The cells are linear in the sense that each cell edge is a straight line.) The filter is designed for high-speed, specialized operation. All other cell types are skipped and produce no output.

To use this filter you must specify an input unstructured grid, and one or more contour values. You can either use the method SetValue() to specify each contour value, or use GenerateValues() to generate a series of evenly spaced contours.

The filter performance varies depending on optional output information. Basically if point merging is required (when PointMerging, InterpolateAttributes, and/or ComputeNormals is enabled), a sorting process is required to eliminate duplicate output points in the isosurface. Otherwise when point merging is not required, a fast path process produces independent triangles representing the isosurface. In many situations the results of the fast path are quite good and do not require additional processing.

Warning: The fast path simply produces output points and triangles (the fast path executes when MergePoints if off; InterpolateAttributes is off; and ComputeNormals is off). Since the fast path does not merge points, it produces many more output points, typically on the order of 5-6x more than when MergePoints is enabled. Adding in the other options point merging, field interpolation, and normal generation results in additional performance impacts. By default the fast path is enabled.; Internal to this filter, a caching iterator is used to traverse the cells that compose the vtkUnstructuredGrid. Maximum performance is obtained if the cells are all of one type (i.e., input grid of homogeneous cell types); repeated switching from different types may have detrimental effects on performance.; For unstructured data, gradients are not computed. Normals are computed if requested; they are "pseudo-normals" in that the normals of output triangles that use a common point are averaged at the point. Alternatively use vtkPolyDataNormals to compute the surface normals.; The output of this filter is subtly different than the more general filter vtkContourGrid. vtkContourGrid eliminates small, degenerate triangles with concident points which are consequently not sent to the output. In practice this makes little impact on visual appearance but may have repercussions if the output is used for modelling and/or analysis.; Input cells that are not of 3D linear type (tetrahedron, hexahedron, wedge, pyramid, and voxel) are simply skipped and not processed.; The filter is templated on types of input and output points, and input scalar type. To reduce object file bloat, only real points (float,double) are processed, and a limited subset of scalar types.; This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.
