Detailed Description
extract geometry for structured grid
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).
The output of this filter is affected by the structured grid blanking. If blanking is on, and a blanking array defined, then those cells attached to blanked points are not output. (Blanking is a property of the input vtkStructuredGrid.)
- Warning:
- 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.

Member Function Documentation
| static vtkStructuredGridGeometryFilter* vtkStructuredGridGeometryFilter::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkPolyDataAlgorithm.
| static int vtkStructuredGridGeometryFilter::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataAlgorithm.
| virtual int vtkStructuredGridGeometryFilter::IsA | ( | const char * | name | ) | [virtual] |
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataAlgorithm.
| static vtkStructuredGridGeometryFilter* vtkStructuredGridGeometryFilter::SafeDownCast | ( | vtkObjectBase * | o | ) | [static] |
Reimplemented from vtkPolyDataAlgorithm.

| void vtkStructuredGridGeometryFilter::PrintSelf | ( | ostream & | os, |
| vtkIndent | indent | ||
| ) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkPolyDataAlgorithm.
| virtual int* vtkStructuredGridGeometryFilter::GetExtent | ( | ) | [virtual] |
Get the extent in topological coordinate range (imin,imax, jmin,jmax, kmin,kmax).
| virtual void vtkStructuredGridGeometryFilter::GetExtent | ( | int | data[6] | ) | [virtual] |
Get the extent in topological coordinate range (imin,imax, jmin,jmax, kmin,kmax).
| void vtkStructuredGridGeometryFilter::SetExtent | ( | int | iMin, |
| int | iMax, | ||
| int | jMin, | ||
| int | jMax, | ||
| int | kMin, | ||
| int | kMax | ||
| ) |
Specify (imin,imax, jmin,jmax, kmin,kmax) indices.
| void vtkStructuredGridGeometryFilter::SetExtent | ( | int | extent[6] | ) |
Specify (imin,imax, jmin,jmax, kmin,kmax) indices in array form.
| virtual int vtkStructuredGridGeometryFilter::RequestData | ( | vtkInformation * | request, |
| vtkInformationVector ** | inputVector, | ||
| vtkInformationVector * | outputVector | ||
| ) | [protected, virtual] |
This is called by the superclass. This is the method you should override.

| ) | [protected, virtual] |
This is called by the superclass. This is the method you should override.
Reimplemented from vtkPolyDataAlgorithm.
| virtual int vtkStructuredGridGeometryFilter::FillInputPortInformation | ( | int | port, |
| vtkInformation * | info | ||
| ) | [protected, virtual] |
Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.
Reimplemented from vtkPolyDataAlgorithm.
