SphericalDreamer: Generating Navigable Immersive 3D Worlds with Panorama Fusion
This work addresses the limitation of existing 3D world generation methods that cannot simultaneously provide full omnidirectional coverage and long-range navigability, benefiting virtual reality and 3D content creation.
SphericalDreamer generates fully immersive, navigable 3D outdoor environments from text prompts, achieving 360°×180° coverage and long-range spatial extent, significantly improving scale and navigability over prior methods.
The generation of immersive and navigable 3D environments is increasingly prevalent with the growing adoption of virtual reality and 3D content. However, recent methods face a fundamental limitation: they cannot produce 3D worlds that simultaneously (i) are navigable over long-range spatial extents and (ii) cover the complete omnidirectional field of view ($360^\circ$ horizontally and $180^\circ$ vertically). To address this challenge, we introduce SphericalDreamer, a method for generating fully immersive and long-range 3D outdoor environments from textual prompts. Our approach is built on the generation of multiple panoramic images, which are subsequently lifted into 3D and fused together while maintaining visual and geometric consistency. SphericalDreamer produces highly detailed, fully immersive 3D environments, while substantially improving scale and navigability compared to prior approaches.
