## Detailed Description

extract geometry for structured points

Date:
  2002/01/22 15:29:24

Revision:
  1.3

vtkImageDataGeometryFilter is a filter that extracts geometry from a structured points dataset. By specifying appropriate i-j-k indices (via the "Extent" instance variable), it is possible to extract a point, a line, a plane (i.e., image), or a "volume" from dataset. (Since the output is of type polydata, 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 volume is given by (0,49, 0,49, 0,0).

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

virtual const char* vtkImageDataGeometryFilter::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkStructuredPointsToPolyDataFilter. Reimplemented in vtkStructuredPointsGeometryFilter.

int vtkImageDataGeometryFilter::IsTypeOf | ( | const char * | type | ) | `[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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkStructuredPointsToPolyDataFilter. Reimplemented in vtkStructuredPointsGeometryFilter.

virtual int vtkImageDataGeometryFilter::IsA | ( | const char * | type | ) | `[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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkStructuredPointsToPolyDataFilter. Reimplemented in vtkStructuredPointsGeometryFilter.

vtkImageDataGeometryFilter* vtkImageDataGeometryFilter::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkStructuredPointsToPolyDataFilter. Reimplemented in vtkStructuredPointsGeometryFilter.

void vtkImageDataGeometryFilter::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 vtkStructuredPointsToPolyDataFilter.

vtkImageDataGeometryFilter* vtkImageDataGeometryFilter::New | ( |  | ) | `[static]`

| Construct with initial extent of all the data Reimplemented from vtkObject. Reimplemented in vtkStructuredPointsGeometryFilter.
