Seed3D 2.0

What is Seed3D 2.0?

Seed3D 2.0 is a new generation of high-precision byte-dancing3D generationBig Model, focusing on solving the core problem of geometry restoration and physically realistic material generation. Its technical report shows that the model has reached the current optimal (SOTA) level in two key indicators: geometry generation and physically-based rendering (PBR) material modeling, and the API has been launched on the Volcano Engine platform to support developers' rapid integration.

Core Features of Seed3D 2.0

1. Highly accurate geometry generation
   • Coarse-to-Fine Two-Stage Strategy::
     • Phase I (overall structure): Coarse-grained geometry is generated by a large-parameter DiT model that establishes the topological relationships and spatial layout of objects.
     • Phase II (detail optimization): Using stage one output as an anchor point, accurately recover sharp edges, thin-walled structures and complex surface details, solving the problems of noise and rotten surfaces in traditional models.
   • Inference of spatial structure: Automatically complement the complete 3D structure of an object (e.g., arrangement of support legs, component connection relationships of an industrial conveyor belt) based on limited visual information (e.g., a single image).
2. Realistic PBR material generation
   • Unified PBR texture modeling: Outputs a complete texture map with diffuse reflection, metallicity, roughness, and other parameters, ensuring that the material remains physically consistent under different lighting conditions.
   • Material Detail EnhancementThe MoE (Mixed Expertise) architecture is used to improve detail performance at high resolution, and the Visual Language Model (VLM) a priori is introduced to enhance the stability of material decomposition in unknown lighting environments.
   • Text and Symbol Reduction: Support high-definition generation of text in product nameplates, packaging and other scenarios to avoid blurring or garbled problems.
3. Downstream Scenario Expansion
   • Part Level Segmentation and Completion: Split complete 3D assets into individual parts and add joint information (e.g., hinges, drawers) to support simulation tasks such as robot grasping and dynamic interaction.
   • Multimodal Scene Generation: Supports text, multi-view image or video inputs, combining multiple 3D assets to generate complete scenes (e.g. digital twin factories, virtual showrooms).
   • Physical simulation engine compatibilityThe output results can be directly accessed to Isaac Sim and other mainstream engines, reducing the manual cost of physical property binding and structural optimization.

How to use Seed3D 2.0?

1. API call::
   • Visit the Volcano Engine platform and apply for Seed3D 2.0 API permissions.
   • Submit input data (e.g. image URL or text description) via HTTP request to get the generated 3D model (e.g. GLB format file).
2. Parameter Configuration::
   • Resolution Adjustment: Select the fineness of the output model (e.g. 512 x 512 or 1024 x 1024) according to the requirements.
   • Material Type: Specify the target material (metal, plastic, fabric, etc.) to optimize the generated effect.
3. Post-processing optimization::
   • Fine-tuning (e.g., chamfer optimization) of the generated white mold using tools such as Blender or Maya.
   • Material parameters are adjusted to match the real lighting environment through a PBR renderer such as Unreal Engine.
4. Scene combinations::
   • Generate multiple 3D assets and manually stitch them together into a complete scene using the text/image input capabilities supported by the model.
   • Export to FBX or USDZ format, compatible with mainstream 3D engines and AR/VR platforms.

Seed3D 2.0 redefines the production-grade standard of 3D generation through architectural innovation and scenario expansion. Its high-precision geometry generation, realistic material modeling, and physical simulation compatibility make it a core tool for industrial manufacturing and body intelligence. Developers can quickly integrate with the Volcano Engine API and combine it with post-processing to realize efficient construction from single drawings to complex scenes.
