Measuring errors for massive triangle meshes

2010 IEEE International Workshop on Multimedia Signal Processing, 2010
Our proposal is a method for computing the distance between two surfaces modeled by massive triangle meshes which can not be both loaded entirely in memory. The method consists in loading at each step a small part of the two meshes and computing the symmetrical distance for these areas. These areas are chosen in such a way as the orthogonal projection,

Compressing Multiresolution Triangle Meshes

2001
In this paper, we consider triangle-based two-dimensional multiresolution complexes, called Multi-Triangulations (MTs), constructed based on a vertex-removal simplification strategy, which is the most common strategy used to build simplified representations of surfaces, e.g., terrains.

Fast processing of triangle meshes using triangle fans

International Conference on Shape Modeling and Applications 2005 (SMI' 05), 2006
This paper presents a technique for decomposing a triangulated model into a set of triangle fans. We show that the triangle fan representation improves the performance of several fundamental geometric algorithms operating over triangle meshes. We present two accelerated algorithms, one for computing the nearest intersection between a ray and a fan of ...

Curvature in Triangle Meshes

2012
In many cases notions from differential geometry can be usefully extended to piecewise planar surfaces, and this chapter covers curvature measures on triangle meshes. A frequently used principle is to obtain a smooth surface approximation and to estimate the curvature from this approximation.

Local subdivision on triangle mesh

2012 International Conference on Audio, Language and Image Processing, 2012
Subdivision has been a very popular technology in graphics at home and abroad. It can be splited into global subdivision and local subdivision, and the methods to subdivide are various including butterfly, modified-butterfly, loop, linear, Catmull-Clark, Doo-Sabin and so on.

Snakes on Triangle Meshes

2005
In this work we introduce a new method for representing and evolving snakes that are constrained to lie on a prescribed surface (triangle mesh). The new representation allows to automatically adapt the snake resolution to the surface tesselation and does not need any (unstable) back-projection operations.

DeepMesh: Auto-Regressive Artist-mesh Creation with Reinforcement Learning

arXiv.org
Triangle meshes play a crucial role in 3D applications for efficient manipulation and rendering. While auto-regressive methods generate structured meshes by predicting discrete vertex tokens, they are often constrained by limited face counts and mesh ...

Single Chart Parameterization of Triangle Meshes

2008
The importance of surface parameterization in the field of Computer Graphics is well understood. Many important applications rely on the construction of a high quality mapping from the 3D surface to a flat domain: texture mapping [1], detail recovering of simplified models [3] and surface re-meshing are the most important and common examples. The first

Model Transduction for Triangle Meshes

Journal of Computer Science and Technology, 2010
This paper proposes a novel method, called model transduction, to directly transfer pose between different meshes, without the need of building the skeleton configurations for meshes. Different from previous retargetting methods, such as deformation transfer, model transduction does not require a reference source mesh to obtain the source deformation ...
