ADMesh - a program for processing triangulated solid meshes


admesh [OPTION]... file


ADMesh 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 fol‐ lowing command line was input: admesh sphere.stl 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.


--x-rotate=angle Rotate CCW about x-axis by angle degrees --y-rotate=angle Rotate CCW about y-axis by angle degrees --z-rotate=angle Rotate CCW about z-axis by angle degrees --xy-mirror Mirror about the xy plane --yz-mirror Mirror about the yz plane --xz-mirror Mirror about the xz plane --scale=factor Scale the file by factor (multiply by factor) --translate=x,y,z Translate the file to x, y, and z --merge=name 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-all 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 --write-off=name Output a Geomview OFF format file called name --write-dxf=name Output a DXF format file called name --write-vrml=name Output a VRML format file called name --help Display this help and exit --version 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.


To 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 short‐ ened 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 or admesh -fdv sphere.stl The following command lines do the same thing: admesh sphere.stl 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.
