MeshGPT: Generating Triangle Meshes with Decoder-Only Transformers [PDF]

arXiv, 2023
We introduce MeshGPT, a new approach for generating triangle meshes that reflects the compactness typical of artist-created meshes, in contrast to dense triangle meshes extracted by iso-surfacing methods from neural fields. Inspired by recent advances in powerful large language models, we adopt a sequence-based approach to autoregressively generate ...

A Triangle Mesh Standardization Method Based on Particle Swarm Optimization. [PDF]

PLoS One, 2016
To enhance the triangle quality of a reconstructed triangle mesh, a novel triangle mesh standardization method based on particle swarm optimization (PSO) is proposed. First, each vertex of the mesh and its first order vertices are fitted to a cubic curve

Simplifying Triangle Meshes in the Wild [PDF]

arXiv
This paper introduces a fast and robust method for simplifying surface triangle meshes in the wild while maintaining high visual quality. While previous methods achieve excellent results on manifold meshes by using the quadric error metric, they suffer from producing high-quality outputs for user-created meshes, which often contain non-manifold ...

IDTMM: Incremental Direct Triangle Mesh Mapping [PDF]

IEEE Robotics and Automation Letters, 2023
This letter presents an incremental algorithm to generate triangle meshes from Light Detection and Ranging (LiDAR) point clouds with mesh refinement. The algorithm produces triangle mesh directly from LiDAR output without storing a dense point cloud to ...

Mesh Simplification Algorithm Based on the Quadratic Error Metric and Triangle Collapse

IEEE Access, 2020
Triangular mesh is a commonly used method for representing 3D models. With the continuous development of 3D modeling and scanning technologies, the complexity of the mesh is increasing.

Triangle mesh skeletonization using non-deterministic voxel thinning and graph spectrum segmentation [PDF]

MATEC Web of Conferences, 2021
In the context of shape processing, the estimation of the medial axis is relevant for the simplification and re-parameterization of 3D bodies. The currently used methods are based on (1) General fields, (2) Geometric methods and (3) voxel-based thinning.

Effects of cropping, smoothing, triangle count, and mesh resolution on 6 dental topographic metrics.

PLoS ONE, 2019
Dental topography is a widely used method for quantifying dental morphology and inferring dietary ecology in animals. Differences in methodology have brought into question the comparability of different studies. Using primate mandibular second molars, we

A novel algorithm for a continuous and fast 3D projection of points on triangulated surfaces for CAM/CAD/CAE applications [PDF]

Journal of King Saud University: Computer and Information Sciences, 2022
In the present work, a novel algorithm for the continuous projection of point triangles belonging to a triangle mesh is presented. The algorithm uses the normals defined at the vertices of the triangle to perform the projection.

Elastic Correspondence between Triangle Meshes

Computer Graphics Forum, 2019
AbstractWe propose a novel approach for shape matching between triangular meshes that, in contrast to existing methods, can match crease features. Our approach is based on a hybrid optimization scheme, that solves simultaneously for an elastic deformation of the source and its projection on the target.

Repairing triangle meshes built from scanned point cloud [PDF]

, 2007
The Reverse Engineering process consists of a succession of operations that aim at creating a digital representation of a physical model. The reconstructed geometric model is often a triangle mesh built from a point cloud acquired with a scanner ...
