3D object inpainting is commonly achieved via multi-view 2D image completion, yet independently inpainted views often suffer from cross-view inconsistencies, leading to blurred textures, geometric discontinuities, and visual artifacts in the reconstructed 3D objects. To overcome these limitations, we propose ObjFiller-3D, a novel method designed for the completion and editing of high-quality and consistent 3D objects. Instead of relying on sparse-view editing or per-view 2D inpainting, our method jointly optimizes a sequence of densely sampled views along a $360^\circ$ trajectory, enabling global coherence across viewpoints. We design a new framework with three complementary components: a Temporal-Driven Generative Encoder for modeling dense-view dependencies, a Semantic-Aware Completion Encoder for object-level inpainting, and a Cycle-Consistent 3D Encoder that enforces global coherence through a closed-loop formulation. Our framework also supports reference-guided 3D inpainting, allowing fine-grained control over appearance. Extensive experiments on diverse datasets demonstrate that ObjFiller-3D significantly outperforms prior methods, achieving higher reconstruction fidelity (PSNR 26.6 vs.\ 15.9 of NeRFiller) and perceptual quality (LPIPS 0.19 vs.\ 0.25 of Instant3dit), while reducing reconstruction time from over 40 minutes to under 10 minutes. These results highlight the effectiveness and practical potential of our approach for real-world 3D editing applications.

翻译：三维物体修复通常通过多视角二维图像补全实现，但独立修复的视角常因跨视角不一致性导致重建物体出现纹理模糊、几何不连续及视觉伪影。为解决上述问题，我们提出ObjFiller-3D——一种专为高质量且一致的三维物体补全与编辑设计的新方法。该方法不依赖稀疏视角编辑或逐视角二维修复，而是沿$360^\circ$轨迹联合优化密集采样视角序列，实现跨视角全局连贯性。我们设计了一个包含三个互补组件的新框架：用于建模密集视角依赖关系的时间驱动生成编码器、用于物体级修复的语义感知补全编码器，以及通过闭环公式强制全局一致性的循环一致三维编码器。该框架还支持参考引导的三维修复，可对物体外观进行精细控制。在多个数据集上的大量实验表明，ObjFiller-3D显著优于现有方法，实现了更高重建保真度（PSNR 26.6对比NeRFiller的15.9）和感知质量（LPIPS 0.19对比Instant3dit的0.25），同时将重建时间从40分钟以上缩短至10分钟以内。这些结果凸显了本方法在实际三维编辑应用中的有效性和实用潜力。项目页面：https://objfiller3d.github.io/ 代码：https://github.com/objfiller3d/ObjFiller-3D 。
