Access control is one of the key steps to ensuring the availability, confidentiality and integrity of system resources. While it has been fully applied in various network systems, it's still relatively new for collaborative CAD. This paper provides a new framework of multi-level access control for collaborative CAD based on hierarchical product modeling. A(More)
Great efforts have been devoted to seamless quadrangulation of triangular mesh for its practical application in constructing surface patches. This type of algorithm sets up a parameterization on the triangular mesh and a re-meshing is carried out then to the quadrangulate mesh. The paper proposes a novel algorithm to quad-segment the triangular mesh. Our(More)
