admesh: a program for processing triangulated solid meshes
NAMEADMesh - a program for processing triangulated solid meshes
SYNOPSISadmesh [OPTION]... file
DESCRIPTIONADMesh is a program for processing triangulated solid meshes. Currently, ADMesh only reads the STL file format that is used for rapid prototyping applications, although it can write STL, VRML, OFF, and DXF files.
By default, ADMesh performs all of the mesh checking and repairing options on the input file. This means that is checks exact, nearby, remove-unconnected, fill-holes, normal-directions, and normal-values. The file type (ASCII or binary) is automatically detected. The input file is not modified unless it is specified by the --write option. If the following command line was input:
The file sphere.stl would be opened and read, it would be checked and fixed if necessary, and the results of processing would be printed out. The results would not be saved.
The default value for tolerance is the length of the shortest edge of the mesh. The default number of iterations is 2, and the default increment is 0.01% of the diameter of a sphere that encloses the entire mesh.
If any of the options --exact, --nearby, --remove-unconnected, --fill-holes, --normal-directions, --reverse-all, --normal-values, or --no-check are given, then no other checks besides that one will be done unless they are specified or unless they are required by ADMesh before the specified check can be done. For example the following command line:
admesh --remove-unconnected sphere.stl
would first do an exact check because it is required, and then the unconnected facets would be removed. The results would be printed and no other checks would be done.
- Rotate CCW about x-axis by angle degrees
- Rotate CCW about y-axis by angle degrees
- Rotate CCW about z-axis by angle degrees
- Mirror about the xy plane
- Mirror about the yz plane
- Mirror about the xz plane
- Scale the file by factor (multiply by factor)
- Translate the file to x, y, and z
- Merge file called name with input file
- -e, --exact
- Only check for perfectly matched edges
- -n, --nearby
- Find and connect nearby facets. Correct bad facets
- -t, --tolerance=tol
- Initial tolerance to use for nearby check = tol
- -i, --iterations=i
- Number of iterations for nearby check = i
- -m, --increment=inc
- Amount to increment tolerance after iteration=inc
- -u, --remove-unconnected Remove facets that have 0 neighbors
- -f, --fill-holes
- Add facets to fill holes
- -d, --normal-directions
- Check and fix direction of normals(ie cw, ccw)
- Reverse the directions of all facets and normals
- -v, --normal-values
- Check and fix normal values
- -c, --no-check
- Don't do any check on input file
- -b, --write-binary-stl=name
- Output a binary STL file called name
- -a, --write-ascii-stl=name
- Output an ascii STL file called name
- Output a Geomview OFF format file called name
- Output a DXF format file called name
- Output a VRML format file called name
- Display this help and exit
- Output version information and exit
The functions are executed in the same order as the options shown here. So check here to find what happens if, for example, --translate and --merge options are specified together. The order of the options specified on the command line is not important.
EXAMPLESTo perform all checks except for nearby, the following command line would be used:
admesh --exact --remove-unconnected --fill-holes --normal-directions --normal-values sphere.stl
Actually, since the exact check is required by ADMesh before remove-unconnected, and remove-unconnected is required before --fill-holes, the above command line could be shortened as follows with the same results:
admesh --fill-holes --normal-directions --normal-values sphere.stl
And again the same results could be achieved using the short options:
admesh -fudev sphere.stl
admesh -fdv sphere.stl
The following command lines do the same thing:
admesh -fundev sphere.stl
admesh -f -u -n -d -e -v sphere.stl
since the -fundev options are implied by default. To eliminate one of the checks, just remove the letter of the check to eliminate from the "word" fundev.
