BRepMAE: Self-Supervised Masked BRep Autoencoders for Machining Feature Recognition
Can Yao, Kang Wu, Zuheng Zheng +2
We propose a masked self-supervised learning framework, called BRepMAE, for automatically extracting a valuable representation of the input computer-aided design (CAD) model to rec…

Efficient Computation of Integer-constrained Cones for Conformal Parameterizations
Wei Du, Qing Fang, Ligang Liu +1
We propose an efficient method to compute a small set of integer-constrained cone singularities, which induce a rotationally seamless conformal parameterization with low distortion…

Polynomial 2D Biharmonic Coordinates for High-order Cages
Shibo Liu, Ligang Liu, Xiao-Ming Fu
We derive closed-form expressions of biharmonic coordinates for 2D high-order cages, enabling the transformation of the input polynomial curves into polynomial curves of any order.…
