Meshy T2：基于流匹配的快速原生网格生成框架
原标题：Meshy T2: Fast Native Mesh Generation with Flow Matching
AI 摘要
Meshy 团队提出 Meshy T2，一种基于流匹配的快速原生网格生成框架。其核心是顶点集网格 VAE，将网格编码为每个顶点的连续潜在标记，并单次解码顶点、边连接和面绕序，无需顶点量化或焊接。生成过程采用由粗到细的两级流匹配模型级联，实现交互式生成速度、面数控制和多部件资产原生支持。实验表明，Meshy T2 在几何保真度上达到最先进水平，端到端图像到网格生成中位时间仅 6 秒，比自回归基线快一个数量级以上。代码和权重将在 GitHub 上提供。

Meshy T2: Fast Native Mesh Generation with Flow Matching Abstract Polygonal meshes are the standard surface representation of modern 3D pipelines, and generating high-quality meshes with artist-style topology is essential for film, gaming, and interactive 3D applications. Mainstream approaches serialize a mesh into a token sequence and decode it autoregressively, which is slow at inference and sensitive to error accumulation, making them impractical for interactive asset creation. We present Mes
