About

Texture an existing geometry mesh using a reference image.

Staged generation: pass the GLB geometry produced by the image-to-3d endpoint (enable_texture=false) together with the reference image. Only v1.5 models support this task.

1. Calling the API#

Install the client#

The client provides a convenient way to interact with the model API.

npm install --save @fal-ai/client

Setup your API Key#

Set FAL_KEY as an environment variable in your runtime.

export FAL_KEY="YOUR_API_KEY"

Submit a request#

The client API handles the API submit protocol. It will handle the request status updates and return the result when the request is completed.

import { fal } from "@fal-ai/client";

const result = await fal.subscribe("hitem3d/hi3d/texture", {
  input: {
    image_url: "https://storage.googleapis.com/falserverless/example_inputs/dog.png",
    mesh_url: "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);

2. Authentication#

The API uses an API Key for authentication. It is recommended you set the FAL_KEY environment variable in your runtime when possible.

API Key#

In case your app is running in an environment where you cannot set environment variables, you can set the API Key manually as a client configuration.
import { fal } from "@fal-ai/client";

fal.config({
  credentials: "YOUR_FAL_KEY"
});

3. Queue#

Submit a request#

The client API provides a convenient way to submit requests to the model.

import { fal } from "@fal-ai/client";

const { request_id } = await fal.queue.submit("hitem3d/hi3d/texture", {
  input: {
    image_url: "https://storage.googleapis.com/falserverless/example_inputs/dog.png",
    mesh_url: "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb"
  },
  webhookUrl: "https://optional.webhook.url/for/results",
});

Fetch request status#

You can fetch the status of a request to check if it is completed or still in progress.

import { fal } from "@fal-ai/client";

const status = await fal.queue.status("hitem3d/hi3d/texture", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
  logs: true,
});

Get the result#

Once the request is completed, you can fetch the result. See the Output Schema for the expected result format.

import { fal } from "@fal-ai/client";

const result = await fal.queue.result("hitem3d/hi3d/texture", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);

4. Files#

Some attributes in the API accept file URLs as input. Whenever that's the case you can pass your own URL or a Base64 data URI.

Data URI (base64)#

You can pass a Base64 data URI as a file input. The API will handle the file decoding for you. Keep in mind that for large files, this alternative although convenient can impact the request performance.

Hosted files (URL)#

You can also pass your own URLs as long as they are publicly accessible. Be aware that some hosts might block cross-site requests, rate-limit, or consider the request as a bot.

Uploading files#

We provide a convenient file storage that allows you to upload files and use them in your requests. You can upload files using the client API and use the returned URL in your requests.

import { fal } from "@fal-ai/client";

const file = new File(["Hello, World!"], "hello.txt", { type: "text/plain" });
const url = await fal.storage.upload(file);

Read more about file handling in our file upload guide.

5. Schema#

Input#

image_url string* required

URL of the reference image used to texture the model. PNG, JPEG and WebP formats are supported, up to 20MB.

mesh_url string* required

URL of the geometry model to texture. Only GLB format is supported (e.g. the geometry output of the image-to-3d endpoint with enable_texture=false).

model ModelEnum

Model version used for texturing. Only v1.5 models support the staged texture task. Default value: "hitem3dv1.5"

Possible enum values: hitem3dv1.5, scene-portraitv1.5

resolution Enum

Texture generation resolution. hitem3dv1.5 accepts 512, 1024, 1536 and 1536pro; scene-portraitv1.5 accepts 1536. Defaults to the model's recommended resolution.

Possible enum values: 512, 1024, 1536, 1536pro

export_format ExportFormatEnum

File format of the generated model. Default value: "glb"

Possible enum values: glb, obj, stl, fbx, usdz

enable_safety_checker boolean

If set to true, input images are checked for safety before processing. Default value: true

{
  "image_url": "https://storage.googleapis.com/falserverless/example_inputs/dog.png",
  "mesh_url": "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb",
  "model": "hitem3dv1.5",
  "export_format": "glb",
  "enable_safety_checker": true
}

Output#

model_mesh File* required

Generated 3D model file.

thumbnail File

Preview image of the generated model, when available.

{
  "model_mesh": {
    "url": "",
    "content_type": "image/png",
    "file_name": "z9RV14K95DvU.png",
    "file_size": 4404019
  }
}

Other types#

File#

url string* required

The URL where the file can be downloaded from.

content_type string

The mime type of the file.

file_name string

The name of the file. It will be auto-generated if not provided.

file_size integer

The size of the file in bytes.
