A Neural Network Framework for Geodesic-Like Curve Computation on Parametric Surfaces
Sheng-Gwo Chen, Chen-Chang Peng
The concept of geodesic-like curves was introduced by Chen in 2010 as a method for estimating shortest paths (geodesics) on parametric surfaces, with its convergence established th…

A new intrinsic numerical method for PDE on surfaces
Sheng-Gwo Chen, Mei-Hsiu Chi, Jyh-Yang Wu
In this note we shall introduce a simple, effective numerical method for solving partial differential equations for scalar and vector-valued data defined on surfaces. Even though w…

A simple effective method for curvatures estimation on triangular meshes
Jyh-Yang Wu, Sheng-Gwo Chen, Mei-Hsiu Chi
To definite and compute differential invariants, like curvatures, for triangular meshes (or polyhedral surfaces) is a key problem in CAGD and the computer vision. The Gaussian curv…
