#include <vtkImageMarchingCubes.h>
Inheritance diagram for vtkImageMarchingCubes:
vtkImageMarchingCubes is a filter that takes as input images (e.g., 3D image region) and generates on output one or more isosurfaces. One or more contour values must be specified to generate the isosurfaces. Alternatively, you can specify a min/max scalar range and the number of contours to generate a series of evenly spaced contour values. This filter can stream, so that the entire volume need not be loaded at once. Streaming is controlled using the instance variable InputMemoryLimit, which has units KBytes.

|
Get the ith contour value. Definition at line 165 of file vtkImageMarchingCubes.h. References ContourValues, and vtkContourValues::GetValue(). |
|
Get a pointer to an array of contour values. There will be GetNumberOfContours() values in the list. Definition at line 172 of file vtkImageMarchingCubes.h. References ContourValues, and vtkContourValues::GetValues(). |
|
Fill a supplied list with contour values. There will be GetNumberOfContours() values in the list. Make sure you allocate enough memory to hold the list. Definition at line 179 of file vtkImageMarchingCubes.h. References ContourValues, and vtkContourValues::GetValues(). |
|
Set the number of contours to place into the list. You only really need to use this method to reduce list size. The method SetValue() will automatically increase list size as needed.

Set/Get the computation of normals. Normal computation is fairly expensive in both time and storage. If the output data will be processed by filters that modify topology or geometry, it may be wise to turn Normals and Gradients off. |

Note that if ComputeNormals is on, gradients will have to be calculated, but will not be stored in the output dataset.

The InputMemoryLimit determines the chunk size (the number of slices requested at each iteration). The units of this limit is KiloBytes. For now, only the Z axis is split. |

This is called by the superclass. This is the method you should override. Reimplemented from vtkPolyDataAlgorithm. |
|
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. |
