单视图快速编辑3D模型，几何一致且细节清晰。
Easy3E: Feed-Forward 3D Asset Editing via Rectified Voxel Flow
- 基于稀疏体素流实现单次前向传播的全局一致变形
- 无需训练即可恢复高频纹理，保真度显著提升
- 适合需要快速高质量3D编辑的工业设计场景
现有3D编辑方法依赖计算量大的逐场景迭代优化，存在多视角不一致问题。本文提出基于TRELLIS生成框架的前向3D编辑方法，可仅凭单视图修改3D模型。针对无训练2D编辑适配结构化3D表示、压缩3D特征中外观保真度瓶颈两大挑战，提出Voxel FlowEdit——在稀疏体素潜在空间中基于编辑驱动的流，实现单次通过下的全局一致3D形变；并设计法向引导的单到多视角生成模块作为外部外观先验，成功恢复高频纹理。实验表明，该方法实现了快速、全局一致且高保真的3D模型编辑。
原文摘要 · Abstract (English)
Existing 3D editing methods rely on computationally intensive scene-by-scene iterative optimization and suffer from multi-view inconsistency. We propose an effective and feed-forward 3D editing framework based on the TRELLIS generative backbone, capable of modifying 3D models from a single editing view. Our framework addresses two key issues: adapting training-free 2D editing to structured 3D representations, and overcoming the bottleneck of appearance fidelity in compressed 3D features. To ensure geometric consistency, we introduce Voxel FlowEdit, an edit-driven flow in the sparse voxel latent space that achieves globally consistent 3D deformation in a single pass. To restore high-fidelity details, we develop a normal-guided single to multi-view generation module as an external appearance prior, successfully recovering high-frequency textures. Experiments demonstrate that our method enables fast, globally consistent, and high-fidelity 3D model editing.
