generate smoothed isocontours from segmented 3D image data (i.e., "label maps")
vtkSurfaceNets3D creates boundary/isocontour surfaces from a label map (e.g., a segmented image) using a threaded, 3D version of the multiple objects/labels Surface Nets algorithm. The input is a 3D image (i.e., volume) where each voxel is labeled (integer labels are preferred to real values), and the output data is a polygonal mesh separating labeled regions / objects. (Note that on output each region [corresponding to a different segmented object] will share points/edges on a common boundary, i.e., two neighboring objects will share the boundary that separates them.) This threaded implementation uses concepts from Flying Edges to achieve high performance and scalability.
The filter implements a contouring operation over a non-continuous scalar field. In comparison, classic contouring methods (like Flying Edges or Marching Cubes) presume a continuous scalar field. In comparison, this method processes non-continuous label maps, which corresponds to discrete regions in an input 3D image (i.e., volume). With a non-continuous scalar function, the usual data interpolation across a continuous function (e.g., interpolation along cell edges) is not possible. Instead, when the edge endpoint voxels are labeled in differing regions, the edge is split and transected by a quad polygon that connects the center points of the voxels on either side of the edge. Later, using a energy minimization smoothing process, the resulting polygonal mesh is adjusted to produce a smoother result. (Constraints on smoothing displacements may be specified to prevent excessive shrinkage and/or object distortion.)
The smoothing process is controlled by setting a convergence measure, the number of smoothing iterations, the step size, and the allowed (constraint) distance that points may move. These can be adjusted to provide the desired result. This class provides a method to access an internal instance of vtkConstrainedSmoothingFilter, through which these smoothing parameters may be specified, and which actually performs the smoothing operation. (Note: it is possible to skip the smoothing process altogether by disabling smoothing [e.g., invoking SmoothingOff()] or setting the number of smoothing iterations to zero. This can be useful when using a different smoothing filter like vtkWindowedSincPolyDataFilter; or if an unsmoothed, aliased output is desired. The reason the smoothing is built in to this filter is to remain faithful to the original published literature describing the Surface Nets algorithm, and for performance reasons since smoothing stencils can be generated on the fly.)
See the following reference for more details about the implementation: W. Schroeder, S. Tsalikis, M. Halle, S. Frisken. A High-Performance SurfaceNets Discrete Isocontouring Algorithm. arXiv:2401.14906. 2024. (http://arxiv.org/abs/2401.14906).
The Surface Nets algorithm was first proposed by Sarah Frisken. Two important papers include the description of surface nets for binary objects (i.e., extracting just one segmented object from a volume) and multi-label (multiple object extraction).
S. Frisken (Gibson), “Constrained Elastic SurfaceNets: Generating Smooth Surfaces from Binary Segmented Data”, Proc. MICCAI, 1998, pp. 888-898.
S. Frisken, “SurfaceNets for Multi-Label Segmentations with Preservation of Sharp Boundaries”, J. Computer Graphics Techniques, 2022.
Note that one nice feature of this filter is that algorithm execution occurs only once no matter the number of object labels / contour values. In many contouring-like algorithms, each separate contour value requires an additional algorithm execution with a new contour value. So in this filter large numbers of contour values do not significantly affect overall speed. The user can specify which objects (i.e., labels) are to be output to the filter. (Unspecified labels are treated as background and not output.)
Besides output geometry defining the surface net, the filter outputs a two-component, cell data array indicating the labels/regions on either side of the polygons composing the output vtkPolyData. (This can be used for advanced operations like extracting shared/contacting boundaries between two objects. The name of this cell data array is "BoundaryLabels".)
Note also that the content of the filter's output can be controlled by specifying the OutputStyle. This produces different output which may better serve a particular workflow. For example, it is possible to produce just exterior boundary faces, or extract selected objects/ labeled regions from the surface net.
Implementation note: For performance reasons, this filter is internally implemented quite differently than described in the literature. The main difference is that concepts from the Flying Edges parallel isocontouring algorithm are used. Namely, parallel, edge-by-edge processing is used to define cell cases, generate smoothing stencils, and produce points and output polygons. Plus the constrained smoothing process is also threaded using a double-buffering approach. For more information on Flying Edges see the paper:

This enum is used to control the production of the filter output.
Different output styles are used to transform the data so they can be used in different workflows, providing tradeoffs between speed, memory, and auxiliary information. By default (OUTPUT_STYLE_DEFAULT) the filter produces a mesh with shared points (i.e., points are not duplicated), and all mesh polygons, both interior and exterior, are produced. OUTPUT_STYLE_BOUNDARY is similar to OUTPUT_STYLE_DEFAULT except that only mesh polygons that are on the boundary are produced (i.e., only polygons that border the background region) - thus no interior polygons are produced. OUTPUT_STYLE_SELECTED is used to extract faces bounding selected regions.

Set a particular label value at label number i.
The index i ranges between (0 <= i < NumberOfLabels). (Note: while labels values are expressed as doubles, the underlying scalar data may be a different type. During execution the label values are cast to the type of the scalar data.) Note the use of "Value" and "Label" when specifying regions to extract. The use of "Value" is consistent with other VTK continuous-scalar field isocontouring algorithms; however the term "Label" is more consistent with label maps. Warning: make sure that the value of the background label (see definition below) is different than any of the specified labels, otherwise the generated cell scalars may be incorrect.

Note that the ConstraintScale is used to adjust the size of the constraint distance or box when set automatically.

If automatic is on, the constraint distance and constraint box will calculated and set (based on the input size of the volume voxel). Note that the ConstraintScale is used to adjust the size of the constraint distance or box when set automatically. (Typically the constraint distance defines a circumscribing sphere around a voxel, and the constraint box is a box with voxel spacing.) If constraints are not set automatically, then the constraint distance and/or constraint box should be set manually.) By default, automatic smoothing constraints are enabled.

Indicate whether to use optimized smoothing stencils.
Optimized stencils (which are on by default) are designed to better smooth sharp edges across the surface net. In some cases it may be desired to disable the use of optimized smoothing stencils.

Get the instance of vtkConstrainedSmoothingFilter used to smooth the extracted surface net.
To control smoothing, access this instance and specify its parameters such as number of smoothing iterations and constraint distance. If you wish to disable smoothing, set SmoothingOff().

Specify the form (i.e., the style) of the output.
Different styles are meant to support different workflows. OUTPUT_STYLE_DEFAULT provides the basic information defining the output surface net. OUTPUT_STYLE_BOUNDARY produces much smaller output since the interior polygon faces are not produced. Finally, OUTPUT_STYLE_SELECTED enables the user to extract a subset of the labeled regions. This is useful because the smoothing operation will occur across all the specified input regions, meaning that the selected regions do not change shape due to changes in the specified input regions. You must specify the selected regions (i.e., labels) to output.

Specify the strategy to triangulate the quads (not applicable if the output mesh type is set to MESH_TYPE_QUADS).
If TRIANGULATE_GREEDY is specified, then quads are triangulated in no particular order. If TRIANGULATED_MIN_EDGE is specified, then trianglate the quad using a minimum-edge-length diagonal. If TRIANGULATED_MIN_AREA is specified, then trianglate the quad to produce a minimum surface area. By default, TRIANGULATE_MIN_EDGE is used. (Slight performance affects may occur, with TRIANGULATION_GREEDY generally the fastest.)

Enable caching of intermediate data.
A common workflow using this filter requires extracting object boundaries (i.e., the isocontour), and then repeatedly rerunning the smoothing process with different parameters. To improve performance by avoiding repeated extraction of the boundary, the filter can cache intermediate data prior to the smoothing process. In this way, the boundary is only extracted once, and as long as only the internal constrained smoothing filter is modified, then boundary extraction will not be reexecuted. By default this is enabled.
