meshgeometry | Mesh geometry tools

meshgeometry is a C++ library. meshgeometry has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

mesh geometry tools. several commands can be chained together, with the same operation appearing many times in the same command line. they are processed sequentially. i/o commands |description ---------------------|---------------- -iformat format_name |force input format (needs to precede imesh) -oformat format_name |force output format (needs to precede omesh) -i filename |input file (also accepts -imesh) -o filename |output file (also accepts -omesh) -odata filename |output data. geometry measurement |description -------------------------------------------------|---------------- -absgi |compute absolute gyrification index -area |surface area -checkorientation |check that normals point outside -centre |move the mesh’s barycentre to the origin -euler |print euler characteristic -foldlength |compute total fold length -size |display mesh dimensions -tris |display number of triangles -verts |display number of vertices -volume |compute mesh volume -curv |compute curvature -depth |compute sulcal depth -areamap |compute surface area per vertex -icurv number_of_iterations |integrated curvature (warning: icurv changes the geometry of the mesh) -isolatedverts |count the number of isolated vertices in the mesh. geometry modification |description -------------------------------------------------|---------------- -add filename |add mesh at filename to the current mesh -average n_meshes path1 path2 …​ pathn |compute an average of n_meshes all of the same topology -barycentricprojection reference_mesh |print barycentric coordinates for each vertex in reference_mesh -fixflip |detect flipped triangles and fix them -fixsmall |detect triangles with an angle >160 -flip |flip normals degrees and fix them -laplacesmooth lambda number_of_iterations |laplace smoothing -level level_value |adds new vertices (and triangles) to the edges that cross level_value in the vertex data
