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…
Outer Contour-driven Ruled Surface Generation for Linear Hot-wire Rough Machining
Zheng Zhang, Kang Wu, Yi-Fei Li +4
We propose a novel method to generate a small set of ruled surfaces that do not collide with the input shape for linear hot-wire rough machining. Central to our technique is a new…
Polynomial 2D Green Coordinates for High-order Cages
Shibo Liu, Ligang Liu, Xiao-Ming Fu
We propose conformal polynomial coordinates for 2D closed high-order cages, which consist of polynomial curves of any order. The coordinates enable the transformation of the input…
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.…
Constructing Boundary-identical Microstructures via Guided Diffusion for Fast Multiscale Topology Optimization
Jingxuan Feng, Lili Wang, Xiaoya Zhai +4
Hierarchical structures exhibit critical features across multiple scales. However, designing multiscale structures demands significant computational resources, and ensuring connect…
Guided Diffusion for Fast Inverse Design of Density-based Mechanical Metamaterials
Yanyan Yang, Lili Wang, Xiaoya Zhai +5
Mechanical metamaterial is a synthetic material that can possess extraordinary physical characteristics, such as abnormal elasticity, stiffness, and stability, by carefully designi…
