In this research, a method for free-form deformation of SLIM (Sparse Low-degree IMplicit) surfaces is presented. By employing a Laplacian based mesh deformation technique, a global deformation is realized as movements of the centers of the local function supports. A graph connectivity for defining t … Continue reading “Laplacian Deformation of Implicit Surfaces”

MeshToSS: Converting Subdivision Surfaces from Dense Meshes
This paper introduces the theoretical aspects of MeshToSS, a software system for converting dense triangle meshes into Loop subdivision surfaces. The software takes mesh-format data such as VRML and transforms it into a subdivision surface that approximates the input mesh. The output is either the c … Continue reading “MeshToSS: Converting Subdivision Surfaces from Dense Meshes”
Multiresolution Interpolation Meshes
We propose a new multiresolution-based shape representation for 3D mesh morphing. Our approach does not use combination operations that caused some serious problems in the past approaches for mesh morphing. Therefore, we can calculate a hierarchical interpolation mesh robustly using two types of sub … Continue reading “Multiresolution Interpolation Meshes”
Approximate Shortest Path on Polyhedral Surface and Its Applications
A new algorithm is proposed for calculating the approximate shortest path on a polyhedral surface. The method mainly uses Dijkstra’s algorithm and is based on selective refinement of the discrete graph of a polyhedron. Although the algorithm is an approximation, it has the significant advantag … Continue reading “Approximate Shortest Path on Polyhedral Surface and Its Applications”
Interactive Homogeneous Remeshing
Unstructured triangular meshes are the most standard representation for surface geometry in computer graphics applications due to their simplicity and flexibility. Especially, meshes with special regular connectivity such as subdivision connectivity and with uniform spatial distribution are more use … Continue reading “Interactive Homogeneous Remeshing”
Metamorphosis of Arbitrary Triangular Meshes
Recently, animations with deforming objects have been frequently used in various computer graphics applications. Metamorphosis (or morphing) of three-dimensional objects is one of the techniques which realizes shape transformation between two or more existing objects. In this paper, we present an ef … Continue reading “Metamorphosis of Arbitrary Triangular Meshes”
Interactive Mesh Fusion Based on Local 3D Metamorphosis
This paper proposes a new mesh modeling scheme, called mesh fusion, based on three-dimensional (3D) mesh-based metamorphosis. We establish the attachment from a part of one mesh to a part of another with smooth boundaries, employing the traditional cutting and pasting operation in conjunction with a … Continue reading “Interactive Mesh Fusion Based on Local 3D Metamorphosis”
