UMo: Unified Sparse Motion Modeling for Real-Time Co-Speech Avatars
Xiaoyu Zhan, Xinyu Fu, Chenghao Yang +9
Speech-driven gestures and facial animations are fundamental to expressive digital avatars in games, virtual production, and interactive media. However, existing methods are either…
BrepGaussian: CAD reconstruction from Multi-View Images with Gaussian Splatting
Jiaxing Yu, Dongyang Ren, Hangyu Xu +5
The boundary representation (B-Rep) models a 3D solid as its explicit boundaries: trimmed corners, edges, and faces. Recovering B-Rep representation from unstructured data is a cha…
Flatten The Complex: Joint B-Rep Generation via Compositional -Cell Particles
Junran Lu, Yuanqi Li, Hengji Li +2
Boundary Representation (B-Rep) is the widely adopted standard in Computer-Aided Design (CAD) and manufacturing. However, generative modeling of B-Reps remains a formidable challen…
MatMart: Material Reconstruction of 3D Objects via Diffusion
Xiuchao Wu, Pengfei Zhu, Jiangjing Lyu +5
Applying diffusion models to physically-based material estimation and generation has recently gained prominence. In this paper, we propose \ttt, a novel material reconstruction fra…
LoG3D: Ultra-High-Resolution 3D Shape Modeling via Local-to-Global Partitioning
Xinran Yang, Shuichang Lai, Jiangjing Lyu +6
Generating high-fidelity 3D contents remains a fundamental challenge due to the complexity of representing arbitrary topologies-such as open surfaces and intricate internal structu…
Actial: Activate Spatial Reasoning Ability of Multimodal Large Language Models
Xiaoyu Zhan, Wenxuan Huang, Hao Sun +11
Recent advances in Multimodal Large Language Models (MLLMs) have significantly improved 2D visual understanding, prompting interest in their application to complex 3D reasoning tas…
