Rodin Generation - Gen-2

Post requests with 'tier=Gen-2' to invoke Gen-2 generation.

Use this API to submit an asynchronous task to our server. You will get a task UUID from the API which can be used to check the status of the the task and download the result when the task is ready.

Pricing

Note: There are no additional fees for parameters. Only addons incur extra charges.

Base Cost: 0.5 credit per generation.
Addons:
- HighPack: Additional 1 credit per generation.

Request

Note: All requests to this endpoint must be sent using multipart/form-data to properly handle the file uploads and additional parameters required for the mesh and texture generation process.

Authentication

This API uses bearer key for authentication. You need to include a valid token in the Authorization header for all requests.

Authorization: Bearer RODIN_API_KEY

Body

Parameter

Type

Description

tier

string

Set the value to Gen-2 to invoke Gen-2 generaion. Required. Tier of generation. The default value is Regular.

images

file/Binary

Images to be used in generation, up to 5 images. As the form data request will preserve the order of the images, the first image will be the image for material generation. For Image-to-3D generation: required (one or more images are needed, maximum 5 images) For Text-to-3D generation: null

prompt

string

A textual prompt to guide the model generation. For Image-to-3D generation: optional (if not provided, an AI-generated prompt based on the provided images will be used) For Text-to-3D generation: required

use_original_alpha

boolean

Default is false. If True, the original transparency channel of the images will be used when processing the image.

seed

number

Optional. A seed value for randomization in the mesh generation, ranging from 0 to 65535 (both inclusive). If not provided, the seed will be randomly generated.

geometry_file_format

string

Optional. The format of the output geometry file. Possible values are glb, usdz, fbx, obj, and stl. Default is glb.

material

string

Optional. The material type. Possible values are PBR, Shaded and All. Default is PBR. PBR: Physically Based Materials, including base color texture, metallicness texture, normal texture and roughness texture, providing high realism and physically accurate over dynamic lighting. Shaded: Only base color texture with baked lighting, providing stylized visuals. All: Both PBR and Shaded will be delivered. None: Asset without material.

quality

string

Optional. The face count of the generated model. Possible values are high, medium, low, and extra-low. For Raw: high: 500k, medium: 150k, low: 20k, extra-low: 2k, Default is high. For Quad: high: 50k, medium: 18k, low: 8k, extra-low: 4k, Default is medium.

quality_override

number

Optional. Customize poly count for generation, providing more accurate control over mesh face count. When mesh_mode = Raw: Range from 500 to 1,000,000. Default is 500,000. When mesh_mode = Quad: Range from 1,000 to 200,000. Default is 18,000. Recommend 150,000+ faces for Gen-2. This parameter is an advanced parameter of quality. When this parameter is invoked, the quality parameter will not take effect.

TAPose

bool

Optional. When generating the human-like model, this parameter control the generation result to T/A Pose. When true, your model will be either T pose or A pose.

bbox_condition

Array of Integer

Optional. This is a controlnet that controls the maxmimum sized of the generated model. This array must contain 3 elements, Width(Y-axis), Height(Z-axis), and Length(X-axis), in this exact fixed sequence (y, z, x).

mesh_mode

string

Optional. It controls the type of faces of generated models, Possible values are Raw and Quad. Default is Quad. The Raw mode generates triangular face models. The Quad mode generates quadrilateral face models. When its value is Raw, addons will be fixed to [].

addons

array of strings

Optional. The default is []. Possible values is HighPack. By selecting HighPack: Generate 4K resolution texture instead of the default 2K. If Quad mode, the number of faces will be ~16 times of the number of faces selected in the quality parameter.

preview_render

bool

Optional. Default is false. If true, an additional high-quality render image will be provided in the download list.

hd_texture

bool

Optional. Default is false. If true, high-quality texture will be provided.

Rodin provides two generation modes:

Image-to-3D:
This mode is automatically selected when you upload one or more images files.
- Single Image: Upload one image file to generate a 3D model.
- Multiple Images: When uploading multiple images, they are automatically treated as multi-view captures of a single object. The first image in the upload order will be used for material generation.
Important Note: Form data requests preserve the order of uploaded images. Ensure your images are in the correct sequence for optimal multi-view processing.
Text-to-3D:
This mode is automatically selected when you do not upload any image files.
- Required Parameter:
  prompt: You must provide a text description to guide the 3D model generation.
- Important: No image files should be uploaded when using Text-to-3D mode.

ControlNet: ControlNet enhances model customization by providing finer control over the generated outputs. It adds several parameters on top of the original request, allowing users to manipulate aspects such as proportions, shapes, and structures of 3D models.

ControlNet introduces the following main parameters to provide advanced control over the model generation process:

BoundingBox ControlNet: The BoundingBox ControlNet allows users to define the proportions of the generated model by specifying the length, width, and height through a draggable bounding box. This is particularly useful when you want the generated object to fit within specific dimensions or adhere to certain spatial constraints.

Example Representation:

{
"bbox_condition": [
      100,
      100,
      100
  ]
}

bbox_condition: An array that specifies the dimensions and scaling factor of the bounding box.
- Elements:
  1. Width (Y-axis):100 units.
  2. Height (Z-axis):100 units.
  3. Length (X-axis):100 uints.
By setting the bbox_condition, you're instructing the model to generate an object that fits within a box of the specified dimensions.

Bounding Box Axis:

      World               

    +z(Height)                                                    
    |                                                
    |                                                        
    |______+y(Width)        
    /                  
   /                      
  /                          
  +x(Length)
