SUMMARY:Autoregressive B-Rep Shape Generation with Parametric Surfaces
DESCRIPTION:Dafei Qin and Rui Xu (University of Hong Kong); Zeyu Shen (Ins
 titute of Software, Chinese Academy of Sciences; University of Chinese Aca
 demy of Sciences); Kaichun Qiao, Hongyang Lin, and Qixuan Zhang (ShanghaiT
 ech University); Huaijin Pi (University of Hong Kong); Lan Xu and Jingyi Y
 u (ShanghaiTech University); Wenping Wang (Texas A&M University); and Taku
  Komura (University of Hong Kong)\n\nParaCAD is a point-cloud-conditioned 
 autoregressive framework for B-Rep generation that directly predicts nativ
 e parametric surface types and continuous parameters via a surface-centric
  tokenization, preserving CAD semantics and downstream editability beyond 
 grid/point-based representations.\n\nInterest Area: Research & Education\n
 \nKeyword: Artificial Intelligence/Machine Learning, Geometry, Modeling\n\
 nRegistration Category: Full Conference Supporter, Full Conference\n\nSess
 ion Chair: Changjian Li (University of Edinburgh)\n\n
