mia-meshfilter(1) General Commands Manual mia-meshfilter(1)

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

input mesh to be filtered
For supported file types see PLUGINS:mesh/io
output mesh that have been filtered
For supported file types see PLUGINS:mesh/io

Help & Info

trace ‐ Function call trace
debug ‐ Debug output
info ‐ Low level messages
message ‐ Normal messages
warning ‐ Warnings
fail ‐ Report test failures

Processing

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

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..

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..

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

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)
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

Virtual IO to and from the internal data pool

Recognized file extensions: .@

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 triangle mesh input/output support

Recognized file extensions: .PLY, .ply

STL mesh io plugin

Recognized file extensions: .STL, .stl

Vista/Simbio triangle mesh input/output support

Recognized file extensions: .-, .V, .VMESH, .v, .vmesh

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>]
