Combinatorial mesh optimization [PDF]
The Visual Computer, 2011 A new mesh optimization framework for 3D triangular surface meshes is presented, which formulates the task as an energy minimization problem in the same spirit as in Hoppe et al. (SIGGRAPH’93: Proceedings of the 20th Annual Conference on Computer Graphics and Interactive Techniques, 1993).

Laplacian mesh optimization [PDF]
Proceedings of the 4th international conference on Computer graphics and interactive techniques in Australasia and Southeast Asia, 2006 We introduce a framework for triangle shape optimization and feature preserving smoothing of triangular meshes that is guided by the vertex Laplacians, specifically, the uniformly weighted Laplacian and the discrete mean curvature normal. Vertices are relocated so that they approximate prescribed Laplacians and positions in a weighted least-squares ...

Optimal mesh signal transforms [PDF]
Geometric Modeling and Processing, 2004. Proceedings, 2004 We describe a simple autoregressive model for 3D mesh geometry based on linear prediction. Assuming a Gaussian error term, we show that the resulting probabilistic distribution is a multivariate Gaussian, which may be singular. Furthermore, if the prediction operator is symmetric positive semi-definite, then its eigenvectors coincide with that of the ...

P2 Mesh Optimization Operators [PDF]
, 2019 Curved mesh generation starting from a P1 mesh relies on mesh deformation and mesh optimization techniques. Mesh optimization techniques consist in locally modifying the mesh in order to improve it with respect to a given quality criterion. This work presents the generalization of two mesh quality-based optimization operators to P2 meshes.

Ordered Statistics Vertex Extraction and Tracing Algorithm (OSVETA)
Advances in Electrical and Computer Engineering, 2012 We propose an algorithm for identifying vertices from three dimensional (3D) meshes that are most important for a geometric shape creation. Extracting such a set of vertices from a 3D mesh is important in applications such as digital watermarking, but ...

On Optimal Bilinear Quadrilateral Meshes [PDF]
Engineering with Computers, 1999 Two different two-dimensional quadrilateral meshes are compared. Both of them are asymptotically optimal quadrilateral meshes for bilinear approximation. In the paper interesting error properties of two types of meshes are presented. Both types of mesh are generated by a coordinate transformation of a regular mesh of squares.
