Tripo3D H3.1 Text to 3D

Tripo3D H3.1 Text to 3D is Tripo AI's high-detail model for turning written object descriptions into 3D assets for concept work and close-up visuals. Its dense geometry emphasizes readable silhouettes and fine parts, while prompt wording, geometry quality, and texture controls let you specify structure and surface appearance. Inspect the returned model in the interactive viewer and download its files for the next asset workflow.

Why choose Tripo3D H3.1 Text to 3D

  • Shape from a promptDescribe one object's main form, proportions, and defining parts to turn a written idea into an inspectable 3D asset.

  • Layered detail controlChoose standard or detailed Geometry Quality, then set a target with Face Limit to control geometry detail and mesh density separately.

  • Materials and mesh optionsChoose textures and PBR materials for the surface, and enable Quad when your asset workflow calls for quad mesh topology.

Parameters

ParameterRequirementDescription
promptRequired

Describe the object, shape, material, and defining details in 1–1,024 characters.

negative_promptOptional

Describe features to exclude from the text-generated object, up to 1,024 characters.

textureOptional

Generate textures. Default: true.

Defaulttrue

Optional integer seed for the intermediate image in Text to 3D.

texture_seedOptional

Optional integer seed for texture generation.

texture_qualityOptional

Texture detail when Texture is enabled: standard or detailed. Default: standard.

Defaultstandarddetailed

How to use

  1. Describe the objectUse Prompt to specify the subject, silhouette, parts, proportions, and materials; add Negative Prompt for features to exclude.

  2. Set asset detailChoose Geometry Quality and Texture Quality, and add Face Limit when you want a target mesh density.

  3. Preview and downloadSelect Run; once the task finishes, rotate the 3D preview and download the returned asset files.

Use cases

  • Concept objectsTurn written ideas for props, decorative pieces, or standalone structures into 3D forms you can inspect from different angles.

  • Close-up assetsBuild a detailed model for visuals where silhouettes, parts, and surface details need closer inspection.

Practical tips

  • Name the subject and overall silhouette first, then add defining parts such as handles or supports and describe the intended material.
  • Record Prompt, Geometry Quality, and the seeds you use when comparing versions; change one setting at a time and inspect the resulting structure.

Tripo3D H3.1 Text to 3D API frequently asked questions

What is the Tripo3D H3.1 Text to 3D API?

Tripo3D H3.1 Text to 3D is a Tripo AI model for generating 3D objects from written descriptions. It turns prompts into inspectable, high-detail assets with geometry quality, texture quality, and PBR material controls. Its dense geometry generation emphasizes silhouettes and fine parts, while prompts and a target face count guide shape and mesh density. You can call it programmatically or try it from the playground above.

How should a Tripo3D H3.1 Text to 3D Prompt describe an object?

Name the main subject and silhouette, then add proportions, defining parts, and surface materials. Prompt accepts 1–1,024 characters and works best when the description stays focused on one object.

How does Tripo3D H3.1 Text to 3D use Negative Prompt?

Put visual features you want to exclude, such as an extra handle or decoration, in Negative Prompt. Keep the desired subject and details in Prompt; Negative Prompt accepts up to 1,024 characters.

What do the three Seeds control in Tripo3D H3.1 Text to 3D?

Model Seed, Image Seed, and Texture Seed correspond to random seeds for model generation, the intermediate image, and texture generation. Record them with your prompt and quality settings when comparing versions.

How can Tripo3D H3.1 Text to 3D set geometry for close-up assets?

Geometry Quality offers standard and detailed modes, while Face Limit accepts a target from 1,000 to 2,000,000 faces. Choose them according to the silhouette and small parts you need to inspect.

How does Tripo3D H3.1 Text to 3D configure PBR materials?

Enable Texture, choose standard or detailed Texture Quality, and set Pbr to true to request physically based rendering materials with the textured model.

When should I choose Tripo3D H3.1 Text to 3D?

Choose Text to 3D when a written concept defines the object's shape, construction, and material. If you have one object image, Tripo3D H3.1 Image to 3D provides an image-based input path.
