Omages: Open-Source 3D Model Generation Project Simplifies Modeling Process
Beijing, China – A new open-source project called Omagesis revolutionizing 3D model generation, offering a simplified and efficient approach to creating realistic 3D objects. Developed by researchers at the Institute of Information Science, Chinese Academy of Sciences, Omages utilizes image diffusion technology to encode geometric and textural information of 3D shapes into 2D images, significantly streamliningthe modeling process.
Omages leverages the power of image diffusion models, a type of AI that generates images by gradually adding and then removing noise. This process allows Omages to capture intricate details of 3D objects and encode theminto 64×64 pixel 2D images, known as multi-charts. Each chart represents a specific aspect of the 3D object, such as its position, segmentation, or normal map.
Omagesis a significant advancement in 3D modeling, explains Dr. Li, the lead researcher on the project. By encoding 3D information into 2D images, we can generate complex 3D objects at much lower resolutions, preserving rich details and significantly improving efficiency.
Key Features of Omages:
- 3D Object Generation: Omages uses image diffusion models to generate 3D objects from 64×64 pixel images.
- Geometric and Textural Encoding: The project encodes both geometric information and textural details of 3D shapes into 2D images.
- Multi-Chart Representation: Omages employs multiple 2D images (charts) to represent different aspects of the 3D object, enabling a comprehensive representation.
- Detail Preservation: Even at low resolutions, Omages can generate 3D objects with rich details.
- Automatic Material Generation: The project utilizesimage diffusion models to automatically generate physically-based rendering materials.
Technical Principles:
- Image Diffusion Models: Omages relies on diffusion processes to generate images, gradually adding noise and then removing it to reconstruct clear images.
- 3D to 2D Encoding: The geometric shape and surface properties of3D objects, such as normals, albedo, metallic, and roughness, are mapped onto 2D images, a process known as encoding.
- Multi-Chart Representation: Omages uses multiple 2D images (charts) to represent different aspects of the 3D object, such as position,segmentation, normals, etc.
- Autoencoding: Omages integrates the geometric and textural information of 3D objects into a unified image representation through autoencoding.
- Denoising Process: During 3D object generation, the model needs to remove noise from noisy images to recover clear 3D shapes and textures.
