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…
InternSVG: Towards Unified SVG Tasks with Multimodal Large Language Models
Haomin Wang, Jinhui Yin, Qi Wei +12
General SVG modeling remains challenging due to fragmented datasets, limited transferability of methods across tasks, and the difficulty of handling structural complexity. In respo…
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…
DOGE: Differentiable Bezier Graph Optimization for Road Network Extraction
Jiahui Sun, Junran Lu, Jinhui Yin +3
Automatic extraction of road networks from aerial imagery is a fundamental task, yet prevailing methods rely on polylines that struggle to model curvilinear geometry. We maintain t…
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…
