generate object boundaries from labelled volumes
<p>
takes as input a volume (e.g., 3D structured point set) of segmentation labels and generates on output one or more models representing the boundaries between the specified label and the adjacent structures. One or more label values must be specified to generate the models. The boundary positions are always defined to be half-way between adjacent voxels. This filter works best with integral scalar values. If ComputeScalars is on (the default), each output cell will have cell data that corresponds to the scalar value (segmentation label) of the corresponding cube. Note that this differs from <a class="el" href="a00988.html" title="generate isosurface(s) from volume">vtkMarchingCubes</a>, which stores the scalar value as point data. The rationale for this difference is that cell vertices may be shared between multiple cells. This also means that the resultant polydata may be non-manifold (cell faces may be coincident). To further process the polydata, users should either: 1) extract cells that have a common scalar value using <a class="el" href="a01707.html" title="extracts cells where scalar value in cell satisfies threshold criterion">vtkThreshold</a>, or 2) process the data with filters that can handle non-manifold polydata (e.g. <a class="el" href="a01887.html" title="adjust point positions using a windowed sinc function interpolation kernel">vtkWindowedSincPolyDataFilter</a>). Also note, Normals and Gradients are not computed. <dl class="warning" compact><dt><b>Warning:</b></dt><dd>This filter is specialized to volumes. If you are interested in contouring other types of data, use the general <a class="el" href="a00323.html" title="generate isosurfaces/isolines from scalar values">vtkContourFilter</a>. If you want to contour an image (i.e., a volume slice), use <a class="el" href="a00989.html" title="generate isoline(s) from structured points set">vtkMarchingSquares</a>. </dd></dl>
