Electronic Geometry Models
Reviewed collection of digital geometry models for research and education in mathematics. The geometry models in this archive cover a broad range of mathematical topics from geometry, topology, and to some extent from numerics. Examples are geometric surfaces, algebraic surfaces, topological knots, simplicial complexes, vector fields, curves on surfaces. All models are accompanied with a unique description. The most important models, the geometry jewels, are reviewed by the Zentralblatt fRr Mathematik.
