Detailed Description
generate isosurface(s) from volume/images
- Date:

- Revision:

1.36
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.
- Warning:
-
This filter is specialized to volumes. If you are interested in contouring other types of data, use the general vtkContourFilter. If you want to contour an image (i.e., a volume slice), use vtkMarchingSquares.
