📝 摘要(中文)
生成模型在图像条件下的3D内容创作方面取得了进展,但从单幅图像生成可控且可执行的3D场景仍然具有挑战性。现有的3D生成方法在空间布局估计上与特定资产生成器耦合,难以共同建模对象语义、度量几何和场景级空间关系。为此,本文提出Fysiverse-3D-Vision,一个统一的视觉-语言-几何框架,旨在从单幅图像生成3D场景重建和可执行资产构建。通过建立共享表示,空间推理与几何重建相互增强,使得对象布局的推断超越了单个资产生成器的限制。实验表明,该框架在几何一致性、布局估计、渲染质量和物理属性理解方面优于现有方法。

📄 摘要(原文)
Generative models have advanced image-conditioned 3D content creation, yet generating controllable and executable 3D scenes from a single image remains challenging. Existing 3D generative approaches can synthesize visually plausible objects and scenes, but their spatial layout estimation is coupled with specific asset generators. They struggle to jointly model object semantics, metric geometry, and scene-level spatial relationships, which are essential for interactive editing, physical simulation, and embodied applications. We propose Fysiverse-3D-Vision, a unified vision-language-geometry framework for generative 3D scene reconstruction and executable asset construction from a single image. We establish a shared representation where spatial reasoning and geometric reconstruction mutually enhance each other, allowing object layouts to be inferred beyond the constraints of individual asset generators. Our model integrates textual supervision, semantic visual cues, and geometric representations within a unified Transformer to capture scene context, metric geometry, and object-level interactions. An object-conditioned layout module performs cross-attention between target object representations and global geometric features to predict object translation, rotation, and scale. Training progressively learns geometry-language alignment, introduces layout reasoning while preserving reconstruction capability, and refines physical consistency through collision-aware optimization. By separating spatial layout reasoning from asset synthesis, Fysiverse-3D-Vision provides an adaptable interface for interactive scene editing, object-level manipulations, and executable 3D content generation. Experiments demonstrate that our framework achieves superior geometric consistency, layout estimation, rendering quality, and physical property understanding compared with existing approaches.
