public class ModelSurfaceExtractorCubes
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 ModelSurfaceExtractorCubes(int iXBound,
                                  int iYBound,
                                  int iZBound,

                                  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

Method Detail

getLevelSurface

public ModelTriangleMesh getLevelSurface(int iLevel,
                                         ViewJProgressBar progressBar)

Construct a level surface from the 3D image managed by the extractor.

Parameters:

iLevel - the desired level value, in [min(image),max(image)]

progressBar - update to display progress during extraction

Returns:

a triangle mesh that represents the level surface
