vtkStructuredGridGeometryFilter - extract geometry for structured grid

Super Class: vtkStructuredGridToPolyDataFilter

Description:

vtkStructuredGridGeometryFilter is a filter that extracts geometry from a structured grid. By specifying appropriate i-j-k indices, it is possible to extract a point, a curve, a surface, or a "volume". Depending upon the type of data, the curve and surface may be curved or planar. The volume is actually a (n x m x o) region of points. The extent specification is zero-offset. That is, the first k-plane in a 50x50x50 structured grid is given by (0,49, 0,49, 0,0).

 

Caveats:

If you don't know the dimensions of the input dataset, you can use a large number to specify extent (the number will be clamped appropriately). For example, if the dataset dimensions are 50x50x50, and you want a the fifth k-plane, you can use the extents (0,100, 0,100, 4,4). The 100 will automatically be clamped to 49.
