Ray-triangular Bézier patch intersection using hybrid clipping algorithm Article

Yan-hong LIU,Juan CAO,Zhong-gui CHEN,Xiao-ming ZENG

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 10, Pages 1018-1030 doi: 10.1631/FITEE.1500390

Abstract: If the ray pierces the patch only once, we locate the parametric value of the intersection to a smallerintersects the patch more than once, Descartes’ rule of signs and a split step are required to isolate the intersectionhave been conducted to illustrate the efficacy of our method in solving ray-triangular Bézier patch intersection

Faster fog-aided private set intersectionwith integrity preserving None

Qiang WANG, Fu-cai ZHOU, Tie-min MA, Zi-feng XU

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 12, Pages 1558-1568 doi: 10.1631/FITEE.1800518

Abstract:

Private set intersection (PSI) allows two parties to compute the intersection of their private setswhile revealing nothing except the intersection.To resolve this problem, we first propose a novel primitive called “faster fog-aided private set intersectionwith integrity preserving”, where the fog conducts delegated intersection operations over encrypted
