NAME
mia-meshfilter - Run filters on a 3D mesh.
SYNOPSIS
mia-meshfilter -i <in-file> -o <out-file> [options] <PLUGINS:mesh/filter>
DESCRIPTION
mia-meshfilter This program runs a series filters on a given input mesh. The filters are given as extra
parameters on the command line and are run in the order in which they are given. To obtain a list of
available filters you may run
'mia-plugin-help mesh/filter' from the command line
OPTIONS
-i --in-file=(required, input); io
input mesh to be filtered
For supported file types see PLUGINS:mesh/io
-o --out-file=(output, required); io
output mesh that have been filtered
For supported file types see PLUGINS:mesh/io
Help & Info
-V --verbose=warning
verbosity of output, print messages of given level and higher priorities. Supported
priorities starting at lowest level are:
trace ‐ Function call trace
debug ‐ Debug output
info ‐ Low level messages
message ‐ Normal messages
warning ‐ Warnings
fail ‐ Report test failures
error ‐ Report errors
fatal ‐ Report only fatal errors

Processing
--threads=-1
Maxiumum number of threads to use for processing,This number should be lower or equal to
the number of logical processor cores in the machine. (-1: automatic estimation).
PLUGINS: mesh/filter
addscale This filter sorts sets the scale parameter for each vertex from a 3D image. Image and mesh are
expected to be in the same physical coordinate space., supported parameters are:
img =(required, string)
3DImage that contains the scale values as a volume image..
deltribynormal
This filter deletes all triangles that have a normal that differs by the given angle from the
provided direction., supported parameters are:
angle = 5; float
Tolerance angle (in degree) that the normal can diviate from the provided direction..
dir =(required, 3dfvector)
Direction the triangle normals are expected to point to. The orientation of the vector is
taken into account..
scale This plug-in provides a filter to scale triangulat meshes by a given strategy, supported
parameters are:
anisoscale = [[1,1,1]]; 3dfvector
Ansiotropic scaling parameter..
box-end = [[256,256,256]]; 3dfvector
Box end for fitbox scaling..
box-start = [[0,0,0]]; 3dfvector
Box start for fitbox scaling..
isoscale = 1; float
Isotropic scaling parameter..
shift = [[0,0,0]]; 3dfvector
Shift mesh after scaling..
strategy = iso-linear; dict
Isotropic scaling parameter.. Supported values are:
iso-linear ‐ Scale and shirt the mesh by scaling it isotropically as given by
parameter 'isoscale' and apply a shift as given by parameter 'shift'
aniso-linear ‐ Scale and shirt the mesh by scaling it anisotropically as given by
parameter 'anisoscale' and apply a shift as given by parameter 'shift'
iso-fitbox ‐ Fit the mesh into the given box by shifting it and apply isotropic
scaling. The box is given by the parameters 'box-start' for upper, left, frontal
corner, and 'box-end' for the lower, right back corner
aniso-fitbox ‐ Fit the mesh into the given box by shifting it and apply anisotropic
scaling. The box is given by the parameters 'box-start' for upper, left, frontal
corner, and 'box-end' for the lower, right back corner
selectbig This filter selects the component with the highest number of triangles from a mesh that is
actually composed of disconnected components. Components are considered to be disconnected if
they don't share a common edge (they might share a common vertex though
(no parameters)
vtxsort This filter sorts the vertices of a mesh according to the given direction. Specifically, the
dot product between the given direction and the vertices will be ordered ascending, supported
parameters are:
dir = [[0,0,1]]; 3dfvector
Sorting direction,.
PLUGINS: mesh/io
datapool Virtual IO to and from the internal data pool
Recognized file extensions: .@
off plugin to load/store some Geomview OFF files. Supported is only the ASCII format 3D meshes with
normales and per-vertex RGB colors. Alpha values and texture coordinates, as well as per face
properties are ignored. Polygons are read and triangulated.
Recognized file extensions: .OFF, .off
ply Ply triangle mesh input/output support
Recognized file extensions: .PLY, .ply
stl STL mesh io plugin
Recognized file extensions: .STL, .stl
vista Vista/Simbio triangle mesh input/output support
Recognized file extensions: .-, .V, .VMESH, .v, .vmesh
vtk A subset of VTK mesh in-and output: Triangle meshes are written, and triangle meshes and
triangle strips are read. Additional per-vertex attributes are supported: 'normals', 'colors'
for three component colors, and 'scale' for a scalar value attached to each vertex. The data is
written by the vtkPolyDataWriter in binary format.
Recognized file extensions: .VTK, .VTKMESH, .vtk, .vtkmesh
EXAMPLE
Run an isotropic scaling on input.vmesh to fit it into the box defined by the corners <0,0,0> -
<128,128,128> and save the result to output.vmesh
mia-meshfilter -i input.vmesh -o output.vmesh
scale:strategy=iso-fitbox,box-start=[<0,0,0>],box-end=[<128,128,128>]
