Tripo3D H3.1 Text to 3D API

Tripo3D H3.1 Text-to-3D

Tripo3D H3.1 Text-to-3D generates a production-ready 3D model directly from a text description. Describe the object you want — the model creates accurate geometry with optional PBR textures, quad mesh topology, and detailed quality tiers for both geometry and texture. No reference image needed.

Why Choose This?

• Text-driven 3D generation Create 3D models from natural language descriptions alone — no photography or reference images required.

• Negative prompt support Specify features to avoid in the generated model for more precise control over the output geometry and style.

• PBR material generation Generate Physically Based Rendering materials alongside the mesh for realistic real-time rendering in game engines and 3D tools.

• Geometry and texture quality tiers Choose between standard and detailed quality independently for geometry and texture.

• Quad mesh support Generate quad (4-sided) mesh topology instead of triangles for cleaner topology compatible with animation and sculpting workflows.

Parameters

Parameter	Required	Description
prompt	Yes	Text description of the 3D object to generate. Max 1024 characters.
negative_prompt	No	Features to avoid in the generated model. Max 1024 characters.
texture	No	Whether to generate textures for the model. Default: true.
pbr	No	Whether to generate PBR materials. Requires texture to be enabled. Default: true.
texture_quality	No	Texture quality: standard (default) or detailed (higher resolution).
geometry_quality	No	Geometry quality: standard (default) or detailed.
auto_size	No	Auto-scale the model to real-world dimensions. Default: false.
quad	No	Generate quad mesh topology instead of triangles. Default: false.

How to Use

1. Write your prompt — describe the object in detail including shape, material, style, and any distinctive features. Max 1024 characters.
2. Add negative prompt (optional) — specify features or styles you want to avoid.
3. Configure texture settings (optional) — enable or disable texture and PBR generation, and choose standard or detailed texture quality.
4. Set geometry quality (optional) — choose standard for faster results or detailed for higher fidelity.
5. Enable quad mesh (optional) — use quad topology for animation or sculpting workflows.
6. Submit — generate and download your 3D model.

• Detailed geometry surcharge: +$0.20
• Quad surcharge: +$0.05
• Default configuration (texture standard, geometry standard, no quad): $0.20

Best Use Cases

• Concept art & prototyping — Rapidly generate 3D assets from written descriptions for ideation and visualization.
• Game asset creation — Create textured 3D props and objects from descriptive prompts without photography.
• Animation & VFX — Use quad mesh output for animation-ready topology compatible with rigging and sculpting.
• AR/VR content — Generate PBR-textured models for immersive application development.
• Developer workflows — Embed text-driven 3D generation into creative pipelines and tools.

Pro Tips

• Be specific and descriptive in your prompt — include shape, material, style, color, and any distinctive features.
• Use negative_prompt to avoid unwanted stylistic elements or geometric artifacts.
• Use detailed geometry quality for complex shapes with fine surface detail.
• Use quad mesh when the model will be used for animation or further sculpting in tools like Blender or ZBrush.
• For objects with a known visual reference, consider using Image-to-3D for more accurate results.

Notes

• Only prompt is required; all other parameters are optional.
• Prompt and negative_prompt are each limited to 1024 characters.
• Please ensure your content complies with Tripo3D's usage policies.
