SHAPE: a synthetic dataset of articulated 3D spacecraft models with optical and mass properties

SHAPE (Spacecraft Hierarchies, Articulation, Physics, Ensembles) is a dataset of 34,000 procedurally generated spacecraft models, made by the SatForm3D generator: 10,000 in an unconditioned regime and 2,000 in each of 12 mission regimes. Each model is one HDF5 file with closed triangle meshes and per-facet reflectance, specularity and emissivity, the component hierarchy with subsystem labels, revolute joints with limits and named deployment states, the mass, centre of mass and inertia tensor, and the seed and configuration digest that regenerate it. The deposit holds 29 archives and two checksum files:- population_<regime>.tar.gz (13 archives): all 34,000 models in HDF5;- blueprints_<regime>.tar.gz (13 archives): the blueprint of every model, from which the generator rebuilds it at any facet size;- multires.tar.gz: 520 models built at five facet sizes from 0.5 to 0.04 m;- samples.tar.gz: 195 models in HDF5, glTF, URDF and OBJ;- docs_and_config.tar.gz: the configuration snapshot, the licences, the data records and the Python loader satform_loader.py;- SHA256SUMS.txt and MANIFEST_SHA256.txt: the SHA-256 of every archive and of the list as a whole. Check a download with: sha256sum -c SHA256SUMS.txt The HDF5 files open in HDFView or myHDF5, and the glTF samples in any glTF viewer. The Python loader needs h5py and numpy. The code of the generator is at https://github.com/paulzap/SHAPE under the Apache-2.0 licence. Data descriptor: Zapevalin, P. R.
