Voronoi Foam Moomin

thingiverse

This design is based on our SIGGRAPH 2016 paper Procedural Voronoi Foams for Additive Manufacturing. Content For each example in this collection, we provide several data sets: Raw volume data of the model without a base. Raw volume data of the model with a flat base. A ply mesh of the surface without a base. A ply mesh of the surface with a flat base. When available, the .tar.gz file used to print the model on the Ember 3D printer. When available, the .b9j file used to print the model on the B9Creator 3D printer. Miscellaneous Notes The surface mesh is obtained by running Marching Cube on the volume data. The surface is unfiltered, but you can run a few steps of Laplacian smoothing on it. The volume data is padded with zeros so that Marching Cube can be run directly on it. The volume data can be opened directly in Paraview (open the .mhd file). Alternatively, the volume data can be read as a 3D numpy array using this Python script. When using the .b9j file, you need to reset the file settings from the B9 software. The reason is that the .b9j has been produced directly from the slice images, using an old version of the file format. Citation You are free to use this data for personal or academic purposes.
