Overview

Request Workflow

The Generation APIs are time and resource consuming, so we designed them to be asynchronous. This means that you submit a task without getting the result immediately.

A typical workflow involves submitting a task to the Rodin Generation/Rodin Gen-2 Generation endpoint, polling for its status, and downloading the generated files once the task is complete. Refer to the Minimal Example section for an example script for the workflow.

Rodin Gen-2

Rodin Gen-2 is our most advanced 3D generation model to date. It adopts the brand-new BANG architecture and is trained with unprecedented 3D data and parameters, reaching a model scale of 10 billion.

Compared to previous versions, Rodin Gen-2 offers the following features:

• 4x improved geometric mesh quality, balancing surface details and structural regularity.

• Recursive part-based generation, dividing and subdividing.

• Support for baked normals to display high-polygon details on low-polygon models.

• HD texture maps.

These features will be gradually rolled out via API in 2025, and you can also access them early on Hyper3D.AI.

Rodin Gen-1&1.5

Rodin Sketch

Rodin Sketch provides fast generation of 3D models, suitable for early-stage prototyping. It produces models with basic geometry and texturing, allowing for quick visualization and iteration. The textures can be requested in Shaded or PBR formats. The model generated will only be in GLB format, thus it will have triangular meshes.

Rodin Regular/Detail/Smooth

Rodin Regular generates 3D models with customizable polygon counts and high-quality texturing. It is ideal for projects that require a good balance of detail and efficiency.

Rodin Detail enhanced details compared to Regular, recommended for intricate results (longer processing time).

Rodin Smooth generate clearer and sharper output than Regular, with slightly longer processing time.

The textures can be requested in Shaded or PBR formats. The model generated can be in a variety of formats (ex. GLB, OBJ, FBX, etc.), and it will have triangular or quad meshes depending on the model format.

High Pack Option

For Rodin Regular, the High Pack option can be utilized for even higher resolution (4K) textures and high-poly models. High-poly model is a higher accuracy model, and the number of the high-poly faces is about 16 times the number of general faces.

Image-to-3D and Text-to-3D

For Rodin Generation, depending on the task parameters you submit to Rodin Generation endpoint, different generation modes are selected. When you upload image files, Rodin selects the Image-to-3D mode. And when you don't upload any image, you have to upload a text prompt, thus the job will be executed in Text-to-3D mode.

Multi-Images Generation

For Rodin Image-to-3D Generation, when you upload more than one image to Rodin Generation endpoint, it will automatically switch to multi-images generation mode.

You can choose the parameters you submit to Rodin Generation endpoint to change the mode of multi-image generation:

• fuse mode - if you are uploading images of multiple objects, fuse mode will combine all the features of all the objects from the images for generation.

• concat mode - if you are uploading images of a single object, concat mode will inform the Rodin model to expect these images to be multi-view images of a single object.
