Multiview to 3D Model — P Series

http
Base URL: https://openapi.tripo3d.ai/v3
Endpoint: POST /generation/multiview-to-model
Generate a 3D model from multiview images using P Series. Optimized for low-poly output with clean topology.
Note
  • This endpoint requires an API Key. Include it in the Authorization header as Bearer {api_key}.
  • This is an asynchronous API. After submitting the request, use the Task Query API to poll for results, or configure a Webhook to receive automatic notifications when the task completes.

Request Parameters

Request Body

inputsobject[] | string[]Required
Three formats — use exactly one, do not mix.
  • view-key (recommended) — Array of objects; each object has exactly one key among front, left, back, right. Values may be a URL, file_token, or nested {url} / {file_token} / {object:{bucket,key}}. Order does not matter; the server canonicalizes to [front, left, back, right].
  • legacy positional — Exactly 4 strings in order [front, left, back, right]. Use an empty string "" to skip a view.
  • task_id — Pass the ID of a previous Image to Multiview or Edit Multiview task to reuse its 4-view output. Only [{"task_id":"<uuid>"}] (single-element array) is accepted — do not mix with view-key or positional slots. The source task must be success with type generate_multiview_image or edit_multiview_image.

For view-key and legacy positional, each image value accepts:

  • file_token — Upload an image via the File Upload API first, then pass the returned token.
    Example: file_abc123
  • URL — A publicly accessible direct link to an image.
    Example: https://example.com/front.png
Notes
  • The front view cannot be omitted. You may omit other views, but at least 2 images are required.
  • All images should depict the same object under consistent lighting.
  • Formats: PNG, JPEG, WebP
  • Recommended resolution: at least 256 × 256 px.
modelstringRequired
P Series model version.
  • P1-20260311 — optimized for low-poly generation.
texture_alignmentstringdefault: original_image
Texture alignment priority.
  • original_image — prioritize matching the input image colors.
  • geometry — prioritize matching the generated geometry.
orientationstringdefault: default
Model orientation.
  • default — automatic orientation.
  • align_image — align the model to the input image viewpoint.
Only effective when texture is true. Has no effect without texture enabled.
model_seedinteger
Random seed for geometry generation. Using the same seed with the same input will produce an identical 3D mesh. If not set, a random seed is used each time.
face_limitinteger
Maximum polycount for the output mesh.
Notes
  • Supported range: 50 – 20,000
  • If omitted, adaptively determined.
For best quality: simple models start from 150 faces, complex models start from 250 faces. Lower values may result in poor generation quality.
texturebooleandefault: true
Whether to generate texture maps for the model. Set to false to get a bare geometry without any textures. Default is true.
pbrbooleandefault: true
Enable PBR material maps (base_color, metallic, roughness, normal).
When pbr is set to true, texture will be automatically forced to true.
texture_seedinteger
Random seed for texture generation. Using the same seed will produce identical textures. If not set, a random seed will be used each time. To get a model with different textures but the same geometry, keep model_seed unchanged and vary texture_seed.
texture_qualitystringdefault: standard
Texture quality level.
  • standard — balanced quality and speed.
  • detailed — higher fidelity, slower generation.
  • extreme — 8K textures, highest fidelity. Costs additional credits compared to detailed.
auto_sizebooleandefault: false
Whether to automatically scale the generated model to real-world dimensions. When enabled, the model size will be in meters, suitable for AR/VR or game engine scenes. Default is false.
compressstring
Compression type.
  • geometry — meshopt compression for reduced file size.
Notes
  • The following parameters are only valid when model ≥ v3.0-20250812: texture_quality, geometry_quality, auto_size, quad, smart_low_poly, generate_parts, compress.
export_uvbooleandefault: true
Controls UV unwrapping. Set false for faster generation and smaller file size.
