public class SurfaceExtractorCubes extends WildMagic.LibImagics.Extraction.ExtractSurfaceCubes
A level surface extractor that is based on decomposing voxels into cubes, assuming a linear interpolation on the cubes, and extracting triangular level sets for those cubes. The resulting level surface is a triangle mesh.

      public SurfaceExtractorCubes(int iXBound, int iYBound, int iZBound, int[] aiData, float fXDelta, float fYDelta, float fZDelta, int[] direction, float[] startLocation, TransMatrix dicomMatrix)
      Create a level surface extractor for a 3D image. The delta input values are important when the voxels are not cubic. For example, a typical MRI might have z-slice spacing about 5 times that of the x and y spacing. In this case, dx = 1, dy = 1, and dz = 5. The idea is that 1 is a 'voxel unit' and the z-slices are spaced by 5 voxel units.
      Parameters:
      iXBound - the number of columns in the 3D image
      iYBound - the number of rows in the 3D image
      iZBound - the number of slices in the 3D image
      aiData - The image data stored in order of slice indices, each slice stored in row-major order. That is, slice z=0 is stored first, slice z=1 is stored next, and so on. In slice z=0, the y=0 row is stored first, the y=1 row is stored next, and so on.
      fXDelta - the relative voxel x-size (in voxel units)
      fYDelta - the relative voxel y-size (in voxel units)
      fZDelta - the relative voxel z-size (in voxel units)
      direction - array of direction factors == 1 or -1.
      startLocation - array of startLocation
      dicomMatrix - DOCUMENT ME!
