Accessibility Analysis for Polyhedral Objects
The set of accessible or visible directions for a surface feature of a solid is the feature’s GAC (Global Accessibility Cone). GACs are useful for high-level planning of inspection operations, and for other applications. This paper presents an algorithm for computing GACs for faces of polyhedral solids. The algorithm involves calculating the “silhouettes” of solids generated by Minkowski operations.
