This collection exhibits certified models from a broad range of geometric subjects like differential geometry, convex geometry, computational geometry, topology, and numerics. The models in this exhibition have been contributed by numerous authors to provide insight into geometric shapes, serve as unique reference models for scientific experiments and allow validation of numerical experiments. Each model in this archive has a unique identification for citation purposes.

A model is represented by a master file which provides a unique and well-defined description of the model. This master file is the reference data set of the geometry model. Additional files are available for preview, printing, or explanatory purposes.

The models in this archive may be viewed and downloaded for educational purposes and scientific experiments. Models in this data base are considered to be published, therefore, any use of a model must include a full scientific citation to the authors of a model, the model identification, and the name of this archive. See the copyright pages for details.
