Convergent discrete Laplace-Beltrami operators over surfaces
Jyh-Yang Wu, Mei-Hsiu Chi, Sheng-Gwo Chen
The convergence problem of the Laplace-Beltrami operators plays an essential role in the convergence analysis of the numerical simulations of some important geometric partial diffe…
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…
