We present a novel algorithm for accurately detecting all contacts, including self-collisions, between deformable models. We precompute a chromatic decomposition of a mesh into non-adjacent primitives using graph coloring algorithms. The chromatic decomposition enables us to check for collisions between non-adjacent primitives using a linear-time culling(More)
The Designers' Workbench is a system, developed by the Advanced Knowledge Technologies (AKT) consortium to support designers in large organizations, such as Rolls- Royce, by making sure that a design is consistent with the specification for the particular design as well as with the company's design rule book(s). Currently, to capture the constraint(More)
In many large engineering design organizations the information systems have developed over time into a set of heterogeneous resources. This makes it difficult for engineers to follow a trail through the resources. This situation becomes particular difficult when the Engineer is new to a company; unfamiliar with the systems and unaware of the history of the(More)

The Designers' Workbench is a system, developed to support designers in large organizations, such as Rolls-Royce, by making sure that the design is consistent with the specification for the particular design as well as with the company's design rule book(s). The evolving design is described against a jet engine ontology. Currently , to capture the(More)
