Hunyuan 3d V3.1 Image To 3d Rapid API Documentation

Playground

Hunyuan 3D V3.1 Rapid is a fast image-to-3D generation model, quickly converting 2D images into 3D models. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Hunyuan 3D V3.1 Rapid is Tencent’s fast 3D generation model that converts a single image into a high-quality 3D model. Simply upload an image of any object — the model generates a complete 3D mesh with textures in seconds. Perfect for rapid prototyping, game assets, e-commerce visualization, and 3D content creation.

Why Choose This?

• Single image input Generate complete 3D models from just one image — no multi-view captures required.

• Rapid generation Fast processing delivers 3D assets quickly for rapid iteration and prototyping.

• High-quality output Produces detailed 3D meshes with accurate geometry and textures.

• Simple workflow One-click generation — upload an image and get a 3D model instantly.

• Ultra-affordable Just $0.0225 per generation — cost-effective for high-volume workflows.

Parameters

How to Use

1. Upload your image — provide a clear image of the object you want to convert to 3D.
2. Run — submit and download your 3D model.

Pricing

Billing Rules

• Flat rate: $0.0225 per generation
• No additional charges for mesh complexity or texture quality

Best Use Cases

• Game Development — Quickly generate 3D assets from concept art or reference images.
• E-commerce — Create 3D product models for interactive shopping experiences.
• Prototyping — Rapidly visualize objects in 3D before committing to full production.
• AR/VR Content — Generate 3D assets for augmented and virtual reality applications.
• 3D Printing — Convert product images into printable 3D models.

Pro Tips

• Use images with clear, uncluttered backgrounds for best results.
• Objects photographed from a 3/4 angle typically produce better 3D geometry.
• Ensure good lighting with minimal shadows on the object.
• Higher resolution images capture more surface detail in the 3D output.
• For complex objects, use images that clearly show the object’s shape and structure.

Notes

• Image is the only required field.
• Output format is a 3D mesh with textures.
• Ensure uploaded image URLs are publicly accessible.
