Attribute-based modeling is a new method to design shapes, anything from animated cloth to terrain. It creates a surface that interpolates any set of given (parametric) curves and points in any configuration, and it interpolates to slopes and curvatures. The points, and the curves with slopes and curvatures are called attributes. Since they are not tied to any underlying topology, as with traditional methods, attributes curves can be chosen to represent the important features of an object. This is one key to its power. Designers are able to focus on the features that define an object. In the traditional method, a designer has to consider a patch layout based on the mathematics of the technique. For example, in a B-spline approach, many of the curves have no design purpose; they exist only to serve B-spline requirements. In attribute-based modeling, key modeling notions, such as multi-sided patches, freeform topology, floating curves and points, general parametric curves, small database and fast computation, are combined into a single modeling representation. Attribute Based Modeling is novel, compact, fast, versatile and supports a good design interface. It is still in a development phase, looking for good collaborators and partners.
