Seed3D 2.0可生成高保真3D内容并支持物理模拟，适合工业设计与游戏开发。
Seed3D 2.0: Advancing High-Fidelity Simulation-Ready 3D Content Generation
- 分阶段生成几何与材质，提升细节质量与压缩效率
- 统一渲染模型实现多视角贴图直接生成，视觉保真度达69%~89.9%胜率
- 支持场景布局、部件分解与无训练关节生成，适配物理引擎
我们提出Seed3D 2.0，一个在Seed3D 1.0基础上显著提升生成保真度、模拟就绪能力与应用范围的3D内容生成系统。在几何方面，采用粗到细两阶段流程分离全局结构与高频细节恢复，并通过局部感知变分自编码器实现更高空间压缩与更高效解码。在纹理与材质生成方面，用统一的基于物理渲染（PBR）模型替代原有的级联流程，直接生成多视角漫反射与金属-粗糙度贴图，结合专家混合（MoE）扩展与视觉语言模型（VLM）语义引导，显著提升材质精度与视觉质量。除单物体生成外，引入一套模拟就绪模型套件，包括场景布局规划、部件感知分解及免训练关节生成，支持跨物理与图形引擎的连贯场景构建与部件级物理交互。大规模人工偏好测试显示，在五款近期商业模型对比中，Seed3D 2.0在带纹理3D资产生成上获得69.0%至89.9%的一致胜率。该系统已开放于https://exp.volcengine.com/ark/vision?_vtm_=0.0.c70961.d701978.0&mode=vision&modelId=doubao-seed3d-2-0-260328&tab=Gen3D。
原文摘要 · Abstract (English)
We present Seed3D 2.0, an advanced 3D content generation system built on Seed3D 1.0, with substantial improvements across generation fidelity, simulation-ready capabilities, and application coverage. For geometry, a coarse-to-fine two-stage pipeline decouples global structure learning from high-frequency detail recovery, while a locality-aware VAE achieves higher spatial compression and more efficient decoding. For texture and material generation, we replace the cascaded pipeline of Seed3D 1.0 with a unified PBR model that directly generates multi-view albedo and metallic-roughness maps, enhanced by Mixture-of-Experts scaling and VLM-based semantic conditioning for improved material precision and visual fidelity. Beyond single-object generation, Seed3D 2.0 introduces a simulation-ready model suite comprising scene layout planning, part-aware decomposition, and training-free articulation generation, enabling coherent scene construction and part-level physical interaction across physics and graphics engines. A large-scale human preference study against five recent commercial models shows that Seed3D 2.0 achieves consistent win rates of 69.0% to 89.9% in textured 3D asset generation. Seed3D 2.0 is available on https://exp.volcengine.com/ark/vision?_vtm_=0.0.c70961.d701978.0&mode=vision&modelId=doubao-seed3d-2-0-260328&tab=Gen3D
