AutoBrep: Autoregressive B-Rep Generation with Unified Topology and Geometry
Xiang Xu, Pradeep Kumar Jayaraman, Joseph G. Lambourne +3
The boundary representation (B-Rep) is the standard data structure used in Computer-Aided Design (CAD) for defining solid models. Despite recent progress, directly generating B-Rep…
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…
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…
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…
HoLa: B-Rep Generation using a Holistic Latent Representation
Yilin Liu, Duoteng Xu, Xingyao Yu +4
We introduce a novel representation for learning and generating Computer-Aided Design (CAD) models in the form of (B-Reps). Our representation u…
CLR-Wire: Towards Continuous Latent Representations for 3D Curve Wireframe Generation
Xueqi Ma, Yilin Liu, Tianlong Gao +2
We introduce CLR-Wire, a novel framework for 3D curve-based wireframe generation that integrates geometry and topology into a unified Continuous Latent Representation. Unlike conve…
