Previous parametric representations of smooth genus-zero surfaces require a collection of abutting patches (e.g. splines, NURBS, recursively subdivided polygons). We introduce a s...

Developable surfaces are modelled with pieces of right circular cones. These cone spline surfaces are well-suited for applications: They possess degree two parametric and implicit...
In this paper we introduce a new framework for geometric modeling that combines implicit and parametric surface representations with volumetric warpings. The framework is based on...
Interactive geometry environments support the creation and exploitation of interactive geometric sketches. However, such environments are often driven in a rigid manner, following...
Type abstraction and intensional type analysis are features seemingly at odds--type abstraction is intended to guarantee parametricity and representation independence, while type ...
