## Request Parameters - Trellis 2 Image to 3D generate request

Parameter

Required

Type

Description

image\_url

Yes

string

URL of the input 2D image to convert into a 3D model. Must be publicly accessible.

resolution

No

integer

Resolution of the initial 3D generation pass. Higher values yield finer detail but longer processing.

ss\_guidance\_strength

No

number

Strength of shape guidance during the initial shape generation stage. Higher values enforce structure fidelity.

ss\_guidance\_rescale

No

number

Rescaling factor applied to shape guidance to prevent overfitting. Helps balance creativity and structure.

ss\_sampling\_steps

No

integer

Number of denoising steps during shape generation. More steps improve quality but increase latency.

ss\_rescale\_t

No

integer

Time rescaling parameter for shape generation. Modulates how guidance changes over time steps.

shape\_slat\_guidance\_strength

No

number

Strength of shape SLAT (Spatial Latent Attention) guidance during refinement.

shape\_slat\_guidance\_rescale

No

number

Rescaling factor for shape SLAT guidance to smooth output.

shape\_slat\_sampling\_steps

No

integer

Number of denoising steps in the shape SLAT refinement stage.

shape\_slat\_rescale\_t

No

integer

Time rescaling value for shape SLAT refinement.

tex\_slat\_guidance\_strength

No

number

Strength of texture SLAT guidance during texturing pass. Controls detail in surface appearance.

tex\_slat\_sampling\_steps

No

integer

Number of denoising steps during texture generation.

tex\_slat\_rescale\_t

No

integer

Time rescaling value for texture SLAT generation.

decimation\_target

No

integer

Target number of polygons in the final mesh. Reduces mesh complexity for performance.

texture\_size

No

integer

Resolution of the generated texture map (e.g., 1024, 2048). Higher values improve texture quality.

remesh

No

boolean

Whether to apply topology-preserving remeshing to improve mesh quality.

remesh\_band

No

integer

Bandwidth parameter for remeshing. Controls edge preservation during topology optimization.

## Status Values

Status

Description

QUEUED

Request accepted, waiting to be processed

PROCESSING

Being processed by the model

COMPLETED

Done — output contains the result

FAILED

Failed — check error field

ERROR

System error — not charged

                    → FAILED
                    → ERROR
```

## Typical Workflow

1.  **Send a generate request** to the API endpoint
2.  **Save the `request_id`** from the response
3.  **Poll** every 5-10 seconds: `GET /v2/requests/status/{request_id}`
4.  **When `status` is `"COMPLETED"`**, download from `output.media_url`

**Tip:** Use `X-Webhook-URL` header to get a callback instead of polling.
