“…To robustly detect the primitive features, an existing curvature-based feature segmentation method (Chen and Feng 2014) is used first. After segmenting the mesh model into various feature patches, the shape of each segmented patch and their parameters can be reliably identified by analysing the signs of its average mean and average Gaussian curvatures (Chen and Feng, 2015).…”

This paper presents a structure-altering feature-based editing scheme for triangle mesh models of primitives for engineering application. With the increasing usage of 3D scanning and 3D printing technologies in product design, triangle mesh has become a vital model format in engineering designs. Coupled with its flexible nature in shape manipulation, many design models are now constructed in a mesh form. However, methods to perform direct feature-based mesh model modifications are lacking. Editing features and their defining parameters is greatly underdeveloped for mesh models compared with their parametric model counterparts. Thus, the proposed scheme aims to enable structure-altering feature-based mesh editing through the imposition (mapping) of a feature information layer on top of the triangle mesh model. Feature-based editing is done on the feature information layer. Through information mapping, the mesh model adapts to changes in the feature information layer, resulting in a geometric representation that accurately reflects the feature information layer content. Large-scale model modifications with structure-altering edits are thus achievable for mesh models, allowing straightforward feature-based model editing without the loss of the flexible mesh representation. Numerous case studies have been done to illustrate the effectiveness of the presented feature-based editing scheme. ARTICLE HISTORY

“…For example, these distributions can be used in image processing to improve compression [10]. Some methods in 3D mesh processing also begin to use distributions, for example to apply segmentation [4] or extract object edges [6].…”

“…In our case, the best results are reached using curvatures, because in reverse engineering, features are extracted from curvature analysis. Some methods use curvatures to segment by discontinuities [3,4] or clustering [7], but are often not robust enough around object edges or are designed for CAD meshes [9,1]. Indeed, curvatures are often wrong around object edges because adjacent points can run over many different features.…”

To cite this version:Silvère AbstractToday, it is increasingly frequent and easy to digitize the surface of real 3D objects. However, the obtained meshes are often inaccurate and noisy. In this paper, we present a method to segment a digitized 3D surface from a real object by analyzing its curvature. Experimental results -applied on real digitized 3D meshes -show the efficiency of our proposed analysis, particularly in a reverse engineering process.
