CityCode: Building Agent-Operable 3D Cities from Sparse Aerial Observations
Jiahui Sun, Ran Bi, Yifei Liu +8
Urban spatial intelligence calls for 3D cities that agents can measure, interpret, and modify across successive tasks. Maintaining such cities as persistent, code-based states requ…
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…
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
