Class SurfaceExtractorCubes

  • All Implemented Interfaces:
    java.io.Serializable
    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.

                             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
