Tubular Sculptures
This paper reviews ways in which many artists have constructed large sculptures from tubular elements, ranging from single cylinders to toroidal or knotted structures, to assemblies of a large number of bent tubes. A few parameterized generators are introduced that facilitate design and evaluation of a variety of such sculptural forms.
متن کامل2-Manifold Sculptures
Many abstract geometrical sculptures have the shape of a (thickened) 2D surface embedded in 3D space. A fundamental theorem about such surfaces states that their topology is captured with just three parameters: orientability, genus, and number of borders. When trying to apply this classification to interesting sculptures of famous artists depicted on the Web, a first non-trivial task is to esta...

Mathematics, as a subject dealing with abstract concepts, poses a special challenge for educators. In students' experience, the subject is often associated with (potentially) unflattering adjectives—"austere", "remote", "depersonalized", and so forth. This paper describes a computer program named HyperGami whose purpose is to alleviate this harsh portrait of the mathematical enterprise. HyperGa...
