VoxHammer: Training-Free Precise and Coherent 3D Editing in Native 3D Space

Lin Li, Zehuan Huang, Haoran Feng +4

3D local editing of specified regions is crucial for game industry and robot interaction. Recent methods typically edit rendered multi-view images and then reconstruct 3D models, b…

Disentanglement in T-space for Faster and Distributed Training of Diffusion Models with Fewer Latent-states

Samarth Gupta, Raghudeep Gadde, Rui Chen +1

We challenge a fundamental assumption of diffusion models, namely, that a large number of latent-states or time-steps is required for training so that the reverse generative proces…

LLMControl: Grounded Control of Text-to-Image Diffusion-based Synthesis with Multimodal LLMs

Jiaze Wang, Rui Chen, Haowang Cui

Recent spatial control methods for text-to-image (T2I) diffusion models have shown compelling results. However, these methods still fail to precisely follow the control conditions…

MOSAIC: Generating Consistent, Privacy-Preserving Scenes from Multiple Depth Views in Multi-Room Environments

Zhixuan Liu, Haokun Zhu, Rui Chen +4

We introduce a diffusion-based approach for generating privacy-preserving digital twins of multi-room indoor environments from depth images only. Central to our approach is a novel…

Balanced 3DGS: Gaussian-wise Parallelism Rendering with Fine-Grained Tiling

Hao Gui, Lin Hu, Rui Chen +8

3D Gaussian Splatting (3DGS) is increasingly attracting attention in both academia and industry owing to its superior visual quality and rendering speed. However, training a 3DGS m…
