Introduction to TRELLIS
TRELLIS is an innovative large-scale model designed for generating high-quality 3D assets. This model stands out due to its ability to generate 3D assets that exhibit intricate details and realism. It translates text or image prompts into various 3D formats, including Radiance Fields, 3D Gaussians, and meshes. This capability showcases the model’s versatility and highlights its potential applications across various industries, from gaming to virtual reality and beyond.
The Foundation of TRELLIS
At the heart of TRELLIS lies the Structured LATent (SLAT) representation, which serves as a unified framework for 3D asset generation. This framework enables the model to decode information into different output formats while retaining high fidelity in both geometry and texture. By integrating a sparsely-populated 3D grid with dense visual features extracted from advanced vision models, TRELLIS effectively captures both structural and textural details.
The Role of Rectified Flow Transformers
The backbone of the TRELLIS model consists of Rectified Flow Transformers, which are tailored specifically for handling the SLAT representation. These transformers are instrumental in processing the complex data structures required for high-quality 3D generation. The integration of these advanced neural architectures allows TRELLIS to efficiently manage the sparsity inherent in 3D data while ensuring robust performance.
Training Details of TRELLIS
TRELLIS has been trained on a substantial dataset comprising 500,000 diverse 3D objects. This extensive training enables the model to understand a wide array of shapes, textures, and forms. With up to 2 billion parameters, TRELLIS demonstrates an impressive capacity for learning and generating complex 3D assets that align closely with user inputs.

Key Features and Capabilities of TRELLIS AI
1. Text to 3D Asset Generation
TRELLIS can generate 3D assets directly from text prompts. Users can input descriptive text, and the model translates these descriptions into detailed 3D representations. This functionality is particularly beneficial for designers and developers looking for rapid prototyping or asset creation.
2. Image to 3D Asset Generation
TRELLIS also supports the generation of 3D models from image prompts. By leveraging visual information, the model enhances its capacity to produce realistic and contextually appropriate 3D assets. This dual capability of processing both text and images makes TRELLIS a versatile tool for creative professionals.
3. Flexible Output Formats
TRELLIS AI 3D generator produces assets in multiple formats. Users can choose from various output types, including Radiance Fields, 3D Gaussians, and meshes, depending on their specific requirements. This flexibility makes TRELLIS an invaluable asset in diverse applications, from game development to architectural visualization.
4. Local Editing Capabilities
Beyond asset generation, TRELLIS offers users robust local editing capabilities. This feature allows for modifications to specific regions of a 3D model, enhancing the creative process by enabling users to refine and adapt their assets easily. Such functionality is particularly useful in iterative design processes, where adjustments are often necessary.
Try Out the Demo of TRELLIS 3D
1. The Hugging Face Demo
To experience the capabilities of TRELLIS firsthand, users can try out the Hugging Face Demo. This interactive platform allows you to generate 3D assets using your images directly.
Upload an Image
Simply drag and drop your image into the designated area or click to upload. You can also choose from the examples.
Generate 3D Asset
Once your image is uploaded, click the “Generate” button. If the image has an alpha channel, it will be used as the mask. Otherwise, the tool utilizes rembg to remove the background automatically.
Extract GLB File
If you are satisfied with the generated 3D asset, you can click “Extract GLB” to extract the GLB file and download it.
2. Gradio Demo
In addition to the Hugging Face demo, TRELLIS also offers a web demo facilitated through app.py. This demo is built on the Gradio framework, which requires additional dependencies to be installed.
To set up the web demo, run the following command in your terminal:
. ./setup.sh --demo
After installing the necessary dependencies, you can launch the demo with the command:
python app.py
Once the demo is running, the terminal will display an address where you can access the demo interface.
TRELLIS Installation
To begin using TRELLIS, you will need to install it on your system. The installation process is straightforward, and a detailed step-by-step guide can be found on the official GitHub repository. The repository provides comprehensive instructions on cloning the repository, installing the necessary dependencies, and setting up the environment to run the TRELLIS model.
