Playground

Hunyuan3D-V2-Mini is a Tencent image-to-3D generative model available on WaveSpeedAI. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Hunyuan3D V2 Mini is part of Tencent’s open-source Hunyuan3D-2 series — a state-of-the-art 3D generation system that transforms 2D images into high-fidelity 3D models with detailed textures. This lightweight version delivers fast, affordable 3D generation without sacrificing quality.

Why It Stands Out

• Single image input: Generate complete 3D models from just one 2D image.
• Fast generation: Completes model generation in as fast as 30 seconds.
• High-fidelity output: Produces detailed 3D models with accurate geometry and high-resolution textures.
• Decoupled architecture: Separates geometry generation and texture synthesis for improved quality.
• Simple workflow: Just upload an image — no 3D expertise required.

Technical Highlights

The Hunyuan3D-2 system adopts a separated process of geometry generation + texture synthesis:

• Geometry Generation (Hunyuan3D-DiT): Based on a flow diffusion model that generates untextured 3D geometric models, with 2.6B parameters, capable of precisely extracting geometric information from input images.

• Texture Synthesis (Hunyuan3D-Paint): Adds high-resolution (4K) textures to geometric models, with 1.3B parameters, supporting multi-view diffusion generation technology to ensure realistic textures and consistent lighting.

By decoupling shape and texture generation, the system effectively reduces complexity and improves generation quality.

Performance and Efficiency

• Fast Generation: Completes model generation in as fast as 30 seconds.
• Accelerated Inference: The optimized version shortens inference time by 50% through guidance distillation techniques.
• Multi-modal Support: Compatible with various input methods and integrations including Blender plugins and Gradio applications.

Parameters

How to Use

1. Upload your image — drag and drop a file or paste a public URL.
2. Click Run and wait for the 3D model to generate.
3. Preview and download the result.

Best Use Cases

• Game Development — Quickly generate 3D assets from concept art or icons.
• App & UI Design — Create 3D icons and UI elements from 2D designs.
• E-commerce — Generate 3D product models for interactive displays.
• 3D Printing — Convert 2D designs into printable 3D models.
• AR/VR Content — Generate 3D objects for augmented and virtual reality.
• Rapid Prototyping — Visualize designs in 3D without manual modeling.

Pricing

Pro Tips for Best Quality

• Use images with clear subjects against simple or transparent backgrounds.
• Front-facing views typically produce the best results.
• Ensure the subject is well-lit and clearly visible in the image.
• Icons and objects with distinct shapes work particularly well.
• Higher resolution source images generally yield more detailed 3D models.

Notes

• Ensure uploaded image URLs are publicly accessible.
• Processing time varies based on image complexity and current queue load.
• For higher quality output, consider using the full Hunyuan3D V2 model.
• Please ensure your content complies with usage guidelines.
