BTFDBB: BTF Datenbank Bonn und Messlabor

OBJECTS2012 Datasets

Here you can download the 3D geometry as triangle meshes and corresponding appearance as compressed BTF files for a number of objects that have been captured using the Dome setups of our department.

All datasets are free to use, modify and re-distribute for research and scholarship purposes. Furthermore, it is allowed to publish images made using the models or the BTF data in a scholary article or book, as long as proper credit is given to the University of Bonn's BTF Database. Some of the datasets (Ganesh, Ivory Figurine, Santa) represent artifacts with religious or cultural significance and improper use might affront certain groups of people. Please respect this fact and try to avoid potentially offending usage.
Any usage of the datasets for commercial purposes is not allowed without our permission and in some cases the permission of third parties.

The data presented here has been captured and processed using the methods described in

Christopher Schwartz, Michael Weinmann, Roland Ruiters and Reinhard Klein "Integrated High-Quality Acquisition of Geometry and Appearance for Cultural Heritage", VAST 2011.

Please acknowledge or cite this work when using the datasets.
In case you are using the food objects you may instead also refer to

You can find four more captured objects that in addition to the processed BTF and geometry include the measured raw image data and HDR combined input data in the OBJECTS2011 dataset section.
