NAME

       meshfix - a surface mesh cleaning and repairing utility

SYNOPSIS

       meshfix <file1> [<file2>] [OPTIONS]

DESCRIPTION

       Meshfix  is  a  surface mesh repairing and cleaning tool. It was written by Marco Attene, Mirko Windhoff,
       Axel Thielscher. The details regarding this tool can be found in the below paper

       M. Attene - A lightweight approach to repairing digitized polygon meshes.  The Visual Computer, 2010. (c)
       Springer.

       Meshfix processes file1 and saves the result to <file1>_fixed.off.  An optionally passed file2 is  merged
       with the first one.

       Accepted input formats are OFF, PLY and STL.

OPTIONS

       This program accepts the following input parameters:

       -a <epsilon_angle>
              Allowed range: 0 < epsilon_angle < 2, default: 0 (degrees)

       -j     Join 2 biggest components if they overlap, remove the rest.

       -jc    Join the closest pair of components.

       -h|(--help)
              Print this help and exit.

       --shells <n>
              Only the n biggest shells are kept.

       -o <output>
              Set the output filename (without extension).

       -q     Quiet mode, don't write much to stdout.

       -u <steps>
              Uniform remeshing of the whole mesh, steps > 0

       --vertices <n>
              Constrain number of vertices to n (only with -u)

       --no-clean
              Don't clean.

       --smooth <n>
              Apply n laplacian smoothing steps.

       -s|(--stl)
              Result is saved in STL     format instead of OFF.

       -w|(--wrl)
              Result is saved in VRML1.0 format instead of OFF.

       --fsmesh <n>
              Result is saved in FreeSurfer format instead of OFF.

       --xshift <d>
              Shift  x-coordinates  of vertices by d when saving output.  Only works with --fsmesh; used to deal
              with small FreeSurfer glitch

       --msh  Result is saved in gmsh format for debugging (including vertex and triangle masks)

       --cut-outer <d>
              Remove triangles of 1st that are outside of the 2nd shell.

       --cut-inner <d>
              Remove triangles of 1st that are inside  of the 2nd shell.  Dilate 2nd by d; Fill holes  and  keep
              only 1st afterwards.

       --decouple-inin <d>
              Treat 1st file as inner, 2nd file as outer component.  Resolve overlaps by moving inners triangles
              inwards.

       --decouple-outin <d>
              Treat 1st file as outer, 2nd file as inner component.  Resolve overlaps by moving outers triangles
              inwards.

       --decouple-outout <d>
              Treat 1st file as outer, 2nd file as inner component.  Resolve overlaps by moving outers triangles
              outwards.  Constrain the min distance between the components > d.

       --fineTuneIn <d> <n>
              Used  to  fine-tune  the  minimal  distance  between surfaces A minimal distance d is ensured, and
              reached in n substeps When using the surfaces for subsequent volume  meshing  by  gmsh  this  step
              prevent too flat tetrahedra

       --fineTuneOut <d> <n>
              Similar  to  --fineTuneIn, but ensures minimal distance in the other direction --dilate <d> Dilate
              the surface by d. d < 0 means shrinking.  --intersect If the mesh contains  intersections,  return
              value  =  1.   --intersect  -o fname.msh If the mesh contains intersections, return value = 1.  In
              addtion, save mesh with highlighted intersections in Gmsh format
