vtkRectilinearGridGeometryFilter - extract geometry for a rectilinear grid

Super Class: vtkRectilinearGridToPolyDataFilter

Description:

vtkRectilinearGridGeometryFilter is a filter that extracts geometry from a rectilinear grid. By specifying appropriate i-j-k indices, it is possible to extract a point, a curve, a surface, or a "volume". 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 rectilinear 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.

Methods:

	void vtkRectilinearGridGeometryFilter ()
	const char *GetClassName ()
	void PrintSelf (unknown & ,vtkIndent )
	static vtkRectilinearGridGeometryFilter *New ()
	int *GetExtent ()
	void SetExtent (int ,int ,int ,int ,int ,int )
	void SetExtent (int *)
	void Execute ()

Detailed Method Descriptions:

Construct with initial extent (0,100, 0,100, 0,0) (i.e., a k-plane).

static vtkRectilinearGridGeometryFilter *New ()

Get the extent in topological coordinate range (imin,imax, jmin,jmax, kmin,kmax).

int *GetExtent ()

Specify (imin,imax, jmin,jmax, kmin,kmax) indices.

void SetExtent (int ,int ,int ,int ,int ,int )

Specify (imin,imax, jmin,jmax, kmin,kmax) indices in array form.

void SetExtent (int *)
