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…
B-repLer: Language-guided Editing of CAD Models
Yilin Liu, Niladri Shekhar Dutt, Changjian Li +1
Computer-Aided Design (CAD) models, given their compactness and precision, remain the industry standard for designing and fabricating engineering objects. However, language-guided…
DualBrep: A Dual-Field Continuous Representation for B-rep Modelling
Yilin Liu, Pradeep Jayaraman, Chinthala Reddy +2
Boundary Representation (B-rep) is the most commonly used data format in Computer-Aided Design (CAD) due to its analytical precision and direct support for parametric editing. Howe…
CHOIR: Contact-aware 4D Hand-Object Interaction Reconstruction
Hao Xu, Yilin Liu, Yinqiao Wang +2
We ask whether everyday open-world monocular videos can be turned into reusable 4D interaction primitives: articulated hand motion, object shape with 6D pose over time, and the whe…
Learning to Solve PDEs on Neural Shape Representations
Lilian Welschinger, Yilin Liu, Zican Wang +1
Solving partial differential equations (PDEs) on shapes underpins many shape analysis and engineering tasks; yet, prevailing PDE solvers operate on polygonal/triangle meshes while…
SAGE: Structure-Aware Generative Video Transitions between Diverse Clips
Mia Kan, Yilin Liu, Niloy Mitra
Video transitions aim to synthesize intermediate frames between two clips, but naive approaches such as linear blending introduce artifacts that limit professional use or break tem…
