Cube 3D - An AI-generated 3D model from Roblox

What is Cube 3D?

Cube 3D is an AI-powered 3D generator from Roblox, efficiently generating 3D models and environments using AI technology. Cube 3D supports generating complete 3D objects directly from text descriptions and is compatible with game engines. Cube 3D improves 3D creation efficiency, reduces manual modeling time, and helps developers quickly generate props or design spaces. The open-source version of Cube 3D will support developers in fine-tuning, plugin development, or training based on their own data to meet personalized needs. Cube 3D will integrate with Roblox's existing AI tools, driving more immersive and personalized user experiences.

Main functions of Cube 3D

• Text generation 3D modelQuickly generate 3D mesh models by inputting text descriptions from users.
• Mesh generation and optimizationIt provides rapid modeling and optimization capabilities, helping developers save time and iterate ideas quickly.
• Scene layout and functionalityPredict scene layout and generate 3D environments with practical functions, such as accessible buildings.
• Open source and customizationCube 3D is open source, allowing developers to fine-tune, extend, or develop plugins based on their own needs.

The technical principles of Cube 3D

• Tokenization of 3D objectsDrawing inspiration from the "tokenization" technique in natural language processing, 3D objects are decomposed into a series of "shape tokens." These tokens, similar to words in a language, are the basic units for building complex 3D models. Based on the learning and prediction of these shape tokens, the model gradually constructs complete 3D objects.
• Deep learning-based prediction modelsUsing deep learning algorithms, especially generative models, to predict 3D shape labels. The model learns from large amounts of 3D data, understands the relationships and combinations between different shapes, and generates new 3D objects.
• Training on native 3D dataUnlike traditional image-reconstruction-based 3D generation methods, Cube 3D is trained using native 3D data.
• Recursive layout predictionThe model is based on recursive prediction. It first determines the layout of the scene, then gradually fills in the shape of each part, and finally builds a complete 3D environment.
