Solid modelling with DESIGNBASE

TL;DR: Volumetric form features which are intrinsic to the shape of a given object are recognized from the boundary information through ASVP decomposition, and hierarchical relationships between the recognized form features are obtained in addition to global spatial information.

TL;DR: The theory of geometric continuity within the subject of CAGD is reviewed in this paper, where the problem of filling an n-sided hole occurring within a smooth rectangular patch complex is considered.

TL;DR: A novel method is described to recognize volumetric form features intrinsic to the shape of a given solid using ASVP decomposition, and how the form feature decomposition is converted into corresponding negative components to represent the removal volume for machining applications.

TL;DR: In this paper, an approach to path planning using a nonlinear programming approach is presented, where the free space of the workspace is represented as a set of inequality constraints of a non-linear programming problem, using vehicle configuration variables.
