ImmerseGen - A 3D world generation framework jointly developed by ByteDance and Zhejiang University

What is ImmerseGen?

ImmerseGen is an innovative 3D world generation framework jointly developed by ByteDance's PICO team and Zhejiang University. Based on user-input text prompts and agent-guided asset design and arrangement, the framework generates compact agents with alpha textures to create panoramic 3D worlds. This approach reduces reliance on complex assets, ensuring the diversity and realism of the generated worlds. ImmerseGen enhances multimodal immersion by incorporating dynamic visual effects and synthesized ambient sound, making it particularly suitable for immersive VR experiences.

Main functions of ImmerseGen

• Basic terrain generationBased on user text input, retrieve basic terrain, apply terrain condition texture synthesis, generate RGBA terrain textures and skyboxes aligned with the basic mesh, forming the basic world.
• Rich environmentLightweight assets are introduced, and an asset agent based on VLM (Visual Language Model) selects appropriate templates, designs detailed asset cues, and determines the arrangement of assets in the scene. Each placed asset is instantiated with an alpha texture through context-aware RGBA texture synthesis.
• Multimodal immersion enhancementAdd dynamic visual effects and synthesized ambient sound effects to the generated scene to enhance the user's immersion.

ImmerseGen's technical principles

• Agent-guided asset design and arrangementThe agent guides the design and arrangement of assets. Based on VLM, the agent understands the text input by the user, selects appropriate asset templates, designs detailed asset prompts, and ensures that the generated assets are consistent with the user's needs.
• Terrain Condition Texture CompositingIn the basic terrain generation stage, terrain condition texture synthesis technology is applied to generate RGBA terrain textures and skyboxes aligned with the basic mesh, ensuring the realism and visual effect of the terrain.
• Context-aware RGBA texture compositingFor each placed asset, context-aware RGBA texture compositing technology is used to generate assets with alpha textures based on the surrounding environment, allowing the assets to better blend into the scene.
• Multimodal fusionAdding dynamic visual effects and synthesized ambient sound effects enhances the user's multimodal immersion, providing a rich experience for both the eyes and ears.

Application scenarios of ImmerseGen

• Virtual Reality (VR) and Augmented Reality (AR)ImmerseGen can generate realistic 3D environments for use in VR scenarios such as virtual tourism and virtual conferences, providing an immersive experience. In the AR field, the generated 3D content is integrated with reality, helping to visualize industrial design, architectural design and other fields.
• Game developmentIt helps developers quickly create game scene prototypes, saving time and effort, allowing them to focus on game logic design, and dynamically generating game environments based on game plot and player behavior, bringing players a rich and diverse experience.
• Architectural DesignGenerate 3D models of buildings and urban environments to facilitate virtual presentations and client communication, allowing clients to experience the planning effects in advance and provide feedback.
• educateIn the field of education, virtual laboratory environments can be created to enhance the fun and interactivity of student learning.
• Film and television productionIt generates virtual scenes for film and television shooting, reducing the cost and time of on-site shooting. The generated 3D content serves as the basis for special effects production, helping special effects teams to quickly generate high-quality visual effects.
