SUMMARY:C^0 Generalized Coons Patches for High-order Cage-based Deformatio
 n
DESCRIPTION:Kaikai Qin, Yunhao Zhou, Chenhao Ying, Yajuan Li, and Chongyan
 g Deng (Hangzhou Dianzi University)\n\nSpace deformations deform the ambie
 nt space and thus implicitly deform the embedded objects. Free-Form Deform
 ation allows high-order deformation to the embedding space, yet the lattic
 e may fail to conform to the object and involves many internal control poi
 nts. Cage-based Deformation utilizes a cage space that conforms to the obj
 ect, obviating the need for additional internal control points, but it is 
 typically linear at edges. In this paper, we propose a simple and general 
 method with both advantages while avoiding their drawbacks, allowing users
  to implement high-order cage-based deformation. To achieve this goal, we 
 introduce a new parametric transfinite interpolation scheme based on gener
 alized barycentric coordinates, which unifies and generalizes the rectangu
 lar and triangular Coons patch. This $C^0$ Generalized Coons patch can be 
 defined not only over $2$D domains but also $3$D domains or even higher-di
 mensional domains, with arbitrary polytopes, even including non-manifold t
 opologies. Moreover, the $C^0$ Generalized Coons patch has an elegant math
 ematical expression.\n\nRegistration Category: Full Access, Full Access Su
