ABSTRACT3D mesh segmentation is a fundamental process for Digital Shape Reconstruction in a variety of applications including Reverse Engineering, Medical Imaging, etc. It is used to provide a high level representation of the raw 3D data which is required for CAD, CAM and CAE. In this paper, we present an exhaustive overview of 3D mesh segmentation methodologies examining their suitability for CAD models. In particular, a classification of the various methods is given based on their corresponding underlying fundamental methodology concept as well as on the distinct criteria and features used in the segmentation process.

Abstract-Skeleton-base-animation methods have been commonly used in the character animations. The process of making skeleton for character animation is a long-winded task requiring manual tweaking. This paper presents a novel method to create an automatic animated skeleton from 3D human geometric model through mesh contraction. An automatically generated skeleton is animated by using Kinect captured human motion. The method first, extract a 1D curve-skeleton from the mesh through mesh contraction with constraints. Secondly, the hierarchical joint-based skeleton (armature) has been generated, using the extracted 1D curve-skeleton of the input mesh automatically. Third, the real-time human motion is captured by using the Kinect device. The Kinect captured motion also converts into a standard skeleton motion BVH (Biovision hierarchical) format. Finally, the Kinect motion is retargeted to animate the resulting skeleton of the mesh through joint mapping. The main objective of the proposed approach is to minimize labor-intensive process of skeleton adjustment for character animation. The results of a mesh generated skeleton and plausible skeleton animation to demonstrate the efficiency of the proposed work. The mesh generated skeleton and Kinect motion skeleton both can be directly useful for mesh skinning, mesh rigging, and motion retargeting to create satisfactory character animation.

“…In recent years, there have been several papers addressing this problem, e.g. (Katz and Tal, 2003;Li et al, 2001;Lee et al, 2005;Shamir, 2004;Katz et al, 2005). These techniques produce very nice decompositions.…”

Keywords:3D shape retrieval, 3D shape matching.Abstract: This paper examines the application of the human vision theories of Marr and Biederman to the retrieval of three-dimensional objects. The key idea is to represent an object by an attributed graph that consists of the object's meaningful components as nodes, where each node is fit to a basic shape. A system that realizes this approach was built and tested on a database of about 400 objects and achieves promising results. It is shown that this representation of 3D objects is very compact. Moreover, it gives rise to a retrieval algorithm that is invariant to non-rigid transformations and does not require normalization.
