Image to 3D Model — P Series

http
Base URL: https://openapi.tripo3d.ai/v3
Endpoint: POST /generation/image-to-model
Generate a 3D model from an image 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

inputstringRequired
Image source. The subject should be clearly visible with minimal occlusion. Accepts the following input types:
Choose exactly one of the following — do not pass multiple types simultaneously.
  • 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/photo.png
  • task_id — The task ID from a previous image generation task (text_to_image or image_to_image). The system automatically extracts the output image.
    Example: task_abc123
Notes
  • Supported formats: PNG, JPEG, WebP
  • Max file size: 20 MB
  • Recommended resolution: at least 256 × 256 px. Subject should be clearly visible with a clean background and minimal occlusion.
modelstringRequired
P Series model version.
  • P1-20260311 — optimized for low-poly generation.
enable_image_autofixbooleandefault: false
Whether to automatically optimize the input image before generation. When enabled, the system will enhance low-resolution or low-quality images to improve 3D generation results. Default is false.
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.
