Microsoft TRELLIS: AI-Powered High-Quality 3D Asset Generation Platform

Microsoft TRELLIS is a groundbreaking AI-driven model designed to generate 3D assets with exceptional quality and efficiency. It uses an innovative approach where users provide text descriptions or images, and TRELLIS transforms them into complex and realistic 3D models. This tool supports various output formats such as radiance fields, 3D Gaussian functions, and traditional meshes, offering high flexibility in 3D rendering and visualization. The core technology of TRELLIS is called SLAT (Structured Latent Representation), which encodes geometric and appearance information into local latent variables anchored on a sparse 3D grid. These latent variables are fused and processed from multi-view image features extracted from powerful vision foundation models.

Key Features:

• Smart AI Generation: TRELLIS uses powerful AI technology to accurately interpret user-provided text instructions or images and automatically generate detailed 3D models, significantly simplifying the 3D modeling process.
• Diverse Output Formats: Supports multiple formats such as radiance fields, 3D Gaussian functions, and traditional meshes to meet the needs of different applications. Users can choose the most suitable format based on project requirements.
• Superior Quality: TRELLIS is renowned for generating high-quality 3D assets with complex geometries and realistic textures, surpassing previous 3D generation methods. It is trained on approximately 500,000 high-quality 3D assets collected from four public datasets and uses pre-trained models with up to 2 billion parameters.
• Convenient Local Editing: Offers local editing capabilities, allowing users to easily modify generated 3D models for customization and variant creation, increasing creative flexibility and freedom. Supports detail variations and region-specific editing without the need for retraining.
• Structured Latent Space: The core of TRELLIS is a generation method based on a structured 3D latent space. It achieves high-quality generation across various 3D representations by introducing an explicit sparse 3D structure in the latent space design and using powerful vision foundation models for information encoding. This method includes a two-stage generation process: first generating a sparse structure, then generating local latent variables attached to it. Modeling uses rectified flow models.
• Beyond Existing Technologies: Through comparisons of reconstruction and generation results, TRELLIS demonstrates superior performance in all evaluation metrics and generation quality compared to other benchmarks and previous methods. Ablation studies also validate the effectiveness of this method’s design.

Application Areas:

The powerful capabilities of TRELLIS make it widely applicable in various fields requiring high-quality 3D content, including:

• Game Development: Quickly generate 3D models for characters, scenes, and props in games, accelerating the game development process.
• Virtual Reality (VR) and Augmented Reality (AR): Create realistic 3D environments and objects needed for immersive experiences.
• Film and Animation Production: Generate high-quality 3D characters, special effects, and scenes.
• Product Design and Prototyping: Quickly create 3D models of products for design evaluation and presentation.

Conclusion:

The launch of Microsoft TRELLIS represents a major breakthrough in 3D asset generation technology. It combines advanced AI technology, diverse output formats, convenient local editing features, and large-scale pre-trained models to provide users with a powerful and versatile 3D content creation platform. Whether you are a game developer, virtual reality designer, or other professional needing 3D content, TRELLIS unleashes unlimited creative potential.
