SynthAorta Dataset

This repository contains the SynthAorta dataset, based on the paper "SynthAorta: A 3D Mesh Dataset of Parametrized Physiological Healthy Aortas" (arXiv:2409.08635). Any new updates or code related to the dataset will be published on the corresponding GitHub repository: https://github.com/domagoj-bosnjak/SynthAorta.

Dataset info

The dataset contains 30 000 synthetic geometries of physiological, healthy aortas including three supraaortic vessels. Specifically, the dataset contains:

Structured hexahedral meshes; 4 refinement levels with 226, 1 792, 14 336 and 114 688 elements, respectively.

Consistent meshes, with the same node numbering for every example.

Centerlines with local radius data, enabling the recovery of the smooth surface using the convolution surface framework.

Code for outputting the meshes to the .msh file format, easily transferrable to other FEM software.

Usage and file formats

All of the data is stored in binary format for efficiency, with more info in the README.txt. Minimal MATLAB/Octave code is uploaded as well, for the input/output of the meshes and skeletons, and elementary visualizations. The meshes are outputted in the standard .msh format, which can be parsed/converted by any modern FEM software or library. 

The examples folder contains extracted meshes for initial visualization, requiring the open-source software Gmsh.

All feedback is welcome, especially if you run into problems or issues using the dataset; contact us at [e-mail] or [e-mail].

本仓库包含SynthAorta数据集，其依托论文《SynthAorta：参数化生理健康主动脉三维网格数据集》（arXiv:2409.08635）构建。本数据集的所有后续更新及相关代码均将发布于对应GitHub仓库：https://github.com/domagoj-bosnjak/SynthAorta。

## 数据集详情
本数据集包含30000个生理健康主动脉的合成几何模型，内置三支主动脉弓上分支血管。具体涵盖以下内容：
1. 结构化六面体网格：共4种细化等级，单元数量分别为226、1792、14336及114688；
2. 一致性网格：所有样本的节点编号均保持统一；
3. 带有局部半径数据的中心线，可通过卷积曲面框架还原出光滑曲面；
4. 支持将网格输出为.msh文件格式的代码，可轻松迁移至其他有限元（Finite Element Method，FEM）软件中。

## 使用方法与文件格式
为提升存储与读取效率，所有数据均以二进制格式存储，详细说明请参阅项目根目录下的README.txt文件。本仓库同时上传了极简版MATLAB/Octave代码，用于实现网格与骨架的输入输出及基础可视化功能。网格可输出为标准.msh格式，可被任意现代有限元软件或类库解析、转换。
examples文件夹中包含用于初步可视化的提取网格，需借助开源软件Gmsh打开查看。
