defines dataset interface
<p>
In VTK, spatial-temporal data is defined in terms of a dataset. The dataset consists of geometry (e.g., points), topology (e.g., cells), and attributes (e.g., scalars, vectors, etc.) <a class="el" href="a00590.html" title="defines dataset interface">vtkGenericDataSet</a> is an abstract class defining this abstraction.<p>
Since <a class="el" href="a00590.html" title="defines dataset interface">vtkGenericDataSet</a> provides a general interface to manipulate data, algorithms that process it tend to be slower than those specialized for a particular data type. For this reason, there are concrete, non-abstract subclasses that represent and provide access to data more efficiently. Note that filters to process this dataset type are currently found in the VTK/GenericFiltering/ subdirectory.<p>
Unlike the <a class="el" href="a00374.html" title="abstract class to specify dataset behavior">vtkDataSet</a> class, <a class="el" href="a00590.html" title="defines dataset interface">vtkGenericDataSet</a> provides a more flexible interface including support for iterators. <a class="el" href="a00590.html" title="defines dataset interface">vtkGenericDataSet</a> is also designed to interface VTK to external simulation packages without the penalty of copying memory (see VTK/GenericFiltering/README.html) for more information. Thus <a class="el" href="a00590.html" title="defines dataset interface">vtkGenericDataSet</a> plays a central role in the adaptor framework.<p>
Please note that this class introduces the concepts of "boundary cells". This refers to the boundaries of a cell (e.g., <a class="el" href="a00012.html">face</a> of a tetrahedron) which may in turn be represented as a cell. Boundary cells are derivative topological features of cells, and are therefore never explicitly represented in the dataset. Often in visualization algorithms, looping over boundaries (edges or faces) is employed, while the actual dataset cells may not traversed. Thus there are methods to loop over these boundary cells.<p>
Finally, as a point of clarification, points are not the same as vertices. Vertices refer to points, and points specify a position is space. Vertices are a type of 0-D cell. Also, the concept of a DOFNode, which is where coefficients for higher-order cells are kept, is a new concept introduced by the adaptor framework (see <a class="el" href="a00579.html" title="defines cell interface">vtkGenericAdaptorCell</a> for more information).<p>
