Seedcoat Suture Tessellation: Amplifying Strength, Toughness, and Auxeticity via Wavy Sutural Tessellation in Plant Seedcoats (Adv. Mater. 36/2018)

Cluster Identification via Voronoi Tessellation

We propose an automated method for detecting galaxy clusters in imaging surveys based on the Voronoi tessellation technique. It appears very promising, expecially for its capability of detecting clusters indipendently from their shape. After a brief explanation of our use of the algorithm, we show here an example of application based on a strip of the Edinburgh/Durham Southern Galaxy Catalogue ...

Instanced Tessellation

Optimal Transport and Tessellation

Optimal transport from the volume measure to a convex combination of Dirac measures yields a tessellation of a Riemannian manifold into pieces of arbitrary relative size. This tessellation is studied for the cost functions cp(z, y) = 1 p d(z, y) and 1 ≤ p < ∞. Geometric descriptions of the tessellations for all p is obtained for compact subsets of the Euclidean space and the sphere. For p = 1 t...

Smooth GPU Tessellation

Models used in real-time graphics are commonly rendered using triangular boundary representations. Triangulation approximates flat surfaces very well, but requires many fine triangles to accurately represent curved surfaces. This project implements two methods for smoothing coarse input meshes using GPU tessellation shaders to obtain smooth surfaces.

Tessellation of Quadratic Elements

Topology-based methods have been successfully used for the analysis and visualization of piecewise-linear functions defined on triangle meshes. This paper describes a mechanism for extending these methods to piecewise-quadratic functions defined on triangulations of surfaces. Each triangular patch is tessellated into monotone regions, so that existing algorithms for computing topological repres...
