3dVolMarchingCubes

Outputs the isosurface of the input volume as an OFF file

Usage: 3dVolMarchingCubes [-i <fileName.vol>] [-t <threshold>] [-a <adjacency>] [-o <output.off>]

Outputs the isosurface of value <threshold> of the volume <fileName.vol> as an OFF file <output.off>. The <adjacency> (0/1) allows to choose between interior (6,18) and exterior (18,6) adjacency.

Allowed options are :

-h [ --help ]                         display this message
-i [ --input ] arg                    the volume file (.vol)
-t [ --threshold ] arg (=1)           the value that defines the isosurface 
                                      in the image (an integer between 0 and 
                                      255).
-a [ --adjacency ] arg (=0)           0: interior adjacency, 1: exterior 
                                      adjacency
-o [ --output ] arg (=marching-cubes.off)
                                      the output OFF file that represents the
                                      geometry of the isosurface

Example:

$ 3dVolMarchingCubes -i $DGtal/examples/samples/lobster.vol -t 30
# we invert the default normol orientation to improve display (-n option):
$ meshViewer -i marching-cubes.off -n   

You should obtain such a result:

Resulting visualization.

You can test on other samples like http://www.tc18.org/code_data_set/3D_greyscale/bonsai.vol.bz2

$ 3dVolMarchingCubes -i bonsai.vol  -t 80

You should obtain such a result:

Resulting visualization.
