“…Note that these three models are only topologically equivalent and have no semantically meaningful correspondences, which would be difficult for previous approaches that require surface-feature points as user input. We further compare our approach to the method of Fan 11 that utilizes Poly-cubes for compatible quadrangulation using the two examples in Figure 6 ( Figure 7 in Reference [11]). Observe in Table 3 that, besides the ease of setting up the base domain, our method greatly improves the L 2 metric in these two examples.…”

Mesh quadrangulation has received increasing attention in the past decade. While previous works have mostly focused on producing a high quality quad mesh of a single model, the connectivity of the quadrangulation is typically difficult to control and varies among models even with similar shapes. In this paper, we propose a novel interactive framework for quadrangulating a set of models collectively with compatible connectivity. Furthermore, we demonstrate its application to 3D mesh morphing. In our approach, the user interactively sketches a skeleton within each model, and our method automatically computes compatible base domains for all models from these skeletons, on which the models are parameterized. With this novel parameterization, it is very easy to generate a pleasing and smooth 3D morphing sequence among these compatible models. The method yields quadrangulation with comparable quality to existing approaches, but greatly simplifies compatible re-meshing among a group of topologically equivalent models, in particular characters and animals models, with direct applications in shape blending and morphing.

In this paper we present a new algorithm for establishing correspondence between objects based on matching of extracted skeletons. First, a point cloud of an input model is scanned. Second, a skeleton is extracted from the scanned point cloud. In the last step, all the extracted skeletons are matched based on valence of vertices and segment lengths. The matching process yields into two direct applications -topological mapping and segment mapping. Topological mapping can be used for detection of joint positions from multiple scans of articulated figures in different poses. Segment mapping can be used for animation transfer and for transferring of arbitrary surface per-vertex properties. Our approach is unique, because it is based on matching of extracted skeletons only and does not require vertex correspondence.

“…(The detailed comparisons among different polycube map construction methods are documented in Section 5.) Because of the highly regular structure, polycube maps are very promising in seamless texture mapping and synthesis [11,2], level-of-detail [12], morphing [3], and T-spline construction [4,5].…”

Polycube map is a global cross-surface parameterization technique, where the polycube shape can roughly approximate the geometry of modeled objects while retaining the same topology. The large variation of shape geometry and its complex topological type in real world applications make it difficult to effectively construct a high-quality polycube that can serve as a good global parametric domain for a given object. In practice, existing polycube-map construction algorithms typically require a large amount of user interaction for either pre-constructing the polycubes with great care or interactively specifying the geometric constraints to arrive at the user-satisfied maps. Hence, it is tedious and labor intensive to construct polycube maps for surfaces of complicated geometry and topology. This paper aims to develop an effective method to construct polycube maps for surfaces with complicated topology and geometry. Using our method, users can simply specify how close the target polycube mimics a given shape in a quantitative way. Our algorithm can both construct a similar polycube of high geometric fidelity and compute a high-quality polycube map in an automatic fashion. In addition, our method is theoretically guaranteed to output a one-to-one map. To demonstrate the efficacy of our method, we apply the automatically-constructed polycube maps in a number of computer graphics applications, such as seamless texture tiling, T-spline construction, and quadrilateral mesh generation.
