Accurate collision response on polygonal meshes
Proceedings Computer Animation 2000, 2002We present a very general geometrical correction method for enforcing collisions and other geometrical constraints between polygonal mesh surfaces. It is based on a global resolution scheme that takes advantage of an efficient use of the conjugate gradient algorithm to find the appropriate displacement of the mesh vertices that would satisfy all the ...

Watermarking 3D Polygonal Meshes in the Mesh Spectral Domain
2001Digital watermarking embeds a structure called watermark into the target data, such as image and 3D polygonal models. The watermark can be used, for example, to enforce copyright and to detect tampering. This paper presents a new robust watermarking method that adds watermark into a 3D polygonal mesh in the mesh's spectral domain.

Polygonal mesh watermarking using Laplacian coordinates
Computer Graphics Forum, 2010AbstractWe propose a watermarking algorithm for polygonal meshes based on the modification of the Laplacian coordinates. More specifically, we first compute the Laplacian coordinates (x,y,z) of the mesh vertices, then construct the histogram of the lengths of the (x,y,z) vectors, and finally, insert the watermark by altering the shape of that histogram.

Making sky lanterns from polygonal meshes
Computers & Electrical Engineering, 2014Releasing sky lanterns is a popular way of celebrating festivals and ceremonies in the Asian countries. This paper presents a computer-aided approach to help novice users to design flyable sky lantern with desired shape. Given a closed up-right 3D model with a user-specified cutting on the bottom, our system optimizes the shape by regularizing the ...

MDS: Quadrilateral Meshes and Polygonal Boundary
2017The following mesh limitations are always supposed to be satisfied: the mesh consists of strictly convex quadrilaterals. Every mesh element is a convex quadrilateral and the angle between any two sequential edges is strictly less than π, any inner edge has at most one boundary vertex, boundary vertices have valence 2 (a corner vertex ...
