Shape Processing: ShapeDNA

LaPy - Laplace-Beltrami Python Library
ShapeDNA is now available as part of the more extensive and highly efficient open source
LaPy Python package:
shapeDNA-tria 1.3 (deprecated binary - Linux and Mac)
ShapeDNA-tria is a package to compute accurate eigenvalues and eigenfunctions of the Laplace Beltrami operator using higher order FEM (with Dirichlet or Neumann boundary condition). You can try out two shape retrieval database examples here: Research:ShapeAnalysis.
  • Computes eigenvalues and eigenfunctions
  • Up to cubic FEM for highly accurate approximation
  • Dirichlet or Neumann boundary condition
  • Input: PLY, SMF,OBJ,OFF, VTK,ASC3d,STL,..
  • Global mesh refinement for coarse meshes
  • Tangential smoothing for low quality meshes
  • Converter: Input/Output in different file formats
Related Publications (see all my publications for more):
This program is a command line tool! The download package (...tar.gz) is a compressed archive containing a single directory.
Linux: unpack it with: tar xzvf shapeDNA-tria.tar.gz
MAC: probably Safari will already decompress the archive, double click the remaining shapeDNA-tria.tar file and it will extract the folder in Downloads. You can then move it anyplace you like.
Open a terminal, change into that directory and call it like: ./shapeDNA-tria ... (don't forget the './') or for Mac: ./shapeDNA-tria-osx . If you call it from a different path, make sure to set the environment variable SHAPEDNA_HOME to point to the directory with the key.txt file.
Register and Download - LINUX and MAC OSX binary:
  • Available to Universities for non-profit research purposes.
  • To download: please register with your university email address below to obtain download link.
  • The software is available as a LINUX and MAC OSX binary only. Windows binaries are not planned in the near future.
  • Instead of an open source C++ release, we now distribute a highly efficient open source LaPy Python Package, including ShapeDNA functionality. The binaries here are deprecated and will not be supported any longer.
  • You may NOT use this software for commercial purposes.
