TopoGS: Planar Reconstruction via Topology-aware 3D Gaussian Splatting
Shanshan Pan, Jiale Chen, Yilin Liu +1
Extracting structured, parametric 3D representations from raw images remains a fundamental challenge in computer vision and graphics. While recent advancements in the 3D Gaussian S…
Building LOD Representation for 3D Urban Scenes
Shanshan Pan, Runze Zhang, Yilin Liu +2
The advances in 3D reconstruction technology, such as photogrammetry and LiDAR scanning, have made it easier to reconstruct accurate and detailed 3D models for urban scenes. Nevert…
Architectural Co-LOD Generation
Runze Zhang, Shanshan Pan, Chenlei Lv +2
Managing the level-of-detail (LOD) in architectural models is crucial yet challenging, particularly for effective representation and visualization of buildings. Traditional approac…
Split-and-Fit: Learning B-Reps via Structure-Aware Voronoi Partitioning
Yilin Liu, Jiale Chen, Shanshan Pan +3
We introduce a novel method for acquiring boundary representations (B-Reps) of 3D CAD models which involves a two-step process: it first applies a spatial partitioning, referred to…
