What is Cube 3D
Cube 3D is a large AI 3D generation model launched by Roblox, capable of efficiently generating 3D models and environments based on AI technology. Cube 3D supports generating complete 3D objects directly from text descriptions and is compatible with game engines. Cube 3D can improve 3D creation efficiency, reduce manual modeling time, and help developers quickly generate props or design spaces. The open-source version of Cube 3D will support developers in fine-tuning, plugin development, or training on their own data to meet personalized needs. Cube 3D will integrate with Roblox's existing AI tools to promote a more immersive and personalized user experience.
Main features of Cube 3D
- Text-to-3D model generation: Users input text descriptions to quickly generate 3D mesh models.
- Mesh generation and optimization: Provides fast modeling and optimization features, helping developers save time and quickly iterate on ideas.
- Scene layout and functionalization: Predicts scene layouts and generates 3D environments with actual functionality, such as enterable buildings.
- Open source and customization: Cube 3D supports open source, and developers can fine-tune, extend, or develop plugins based on their own needs.
Technical principles of Cube 3D
- "Tokenization" of 3D objects: Drawing on the "tokenization" technique in natural language processing, 3D objects are decomposed into a series of "shape tokens." Tokens are similar to words in language and are the basic units for building complex 3D models. Based on learning and predicting shape tokens, the model gradually constructs complete 3D objects.
- Deep learning-based prediction model: Uses deep learning algorithms, especially generative models, to predict 3D shape tokens. The model learns from large amounts of 3D data, understands the relationships and combinations between different shapes, and generates new 3D objects.
- Native 3D data training: Unlike traditional 3D generation methods based on image reconstruction, Cube 3D is trained on native 3D data.
- Recursive layout prediction: The model is based on recursive prediction, first determining the scene layout, then gradually filling in the shapes of each part, and finally constructing a complete 3D environment.
