UniBRep: Learning Unified Geometry and Topology for Image-conditioned B-Rep Generation
Haiyang Ying, Allen Tu, Jiaye Wu +2
Generating a boundary representation (B-rep) conditioned on a single image requires faithful reconstruction of geometry, valid topology, and support for complex shapes. We present…

SpeeDe3DGS: Speedy Deformable 3D Gaussian Splatting with Temporal Pruning and Motion Grouping
Allen Tu, Haiyang Ying, Alex Hanson +3
Dynamic extensions of 3D Gaussian Splatting (3DGS) achieve high-quality reconstructions through neural motion fields, but per-Gaussian neural inference makes these models computati…

SketchSplat: 3D Edge Reconstruction via Differentiable Multi-view Sketch Splatting
Haiyang Ying, Matthias Zwicker
Edges are one of the most basic parametric primitives to describe structural information in 3D. In this paper, we study parametric 3D edge reconstruction from calibrated multi-view…
