LumiTokens: 3D Relighting via Token-Space Lighting Transformation
Yiwen Chen, Matheus Gadelha, Huaizu Jiang
Existing 3D relighting methods operate through either explicit material decomposition, diffusion-based view-space generation, or a combination of both, requiring full recomputation…

HouseCrafter: Lifting Floorplans to 3D Scenes with 2D Diffusion Model
Hieu T. Nguyen, Yiwen Chen, Vikram Voleti +2
We introduce HouseCrafter, a novel approach that can lift a floorplan into a complete large 3D indoor scene (e.g., a house). Our key insight is to adapt a 2D diffusion model, which…

IT3D: Improved Text-to-3D Generation with Explicit View Synthesis
Yiwen Chen, Chi Zhang, Xiaofeng Yang +4
Recent strides in Text-to-3D techniques have been propelled by distilling knowledge from powerful large text-to-image diffusion models (LDMs). Nonetheless, existing Text-to-3D appr…
