Abstract:
Reusing engineering data has opened a new opportunity to improve product quality, shorten design lead-time and reduce costs using existing know-how within the design process. Geometrical aspects or 3D shape information of a product is an essential data which can be reused in CAD software. In order to compare and retrieve the existing 3D models, having a precise computational representation of a shape, so-called shape index or shape signature, is a main challenge. The shape signature is often used for the shape similarity comparison. There are several specifications for a shape signature like quick to compute, easy to index, invariant under transformation, independent of 3D representations, tessellation, genus or topology. The algorithms or the methods which decompose a shape into a signature can be classified into seven main classes. This paper aims to focus on the discussion of the first three methods, i.e., Invariant-based methods, Harmonics-based methods, and Graph-based methods, and provide the related literature review on their underlying approaches with highlighting methodologies, advantages and disadvantages
