Accurate, simple and efficient triangulation of a polygon by ear removal with lowest memory consumption

Ceylon Journal of Science, 2016
Polygons can conveniently represent real world objects. In automatic character recognition, shapes of individual letters are represented by polygons. In robotics, obstacles are represented using polygons.

Morphing of Triangular Meshes in Shape Space [PDF]

, 2008
We present a novel approach to morph between two isometric poses of the same non-rigid object given as triangular meshes. We model the morphs as linear interpolations in a suitable shape space $\mathcal{S}$.

Drawing Area-Proportional Euler Diagrams Representing Up To Three Sets [PDF]

, 2013
Area-proportional Euler diagrams representing three sets are commonly used to visualize the results of medical experiments, business data, and information from other applications where statistical results are best shown using interlinking curves ...

Polygon Laplacian Made Simple

Computer graphics forum (Print), 2020
The discrete Laplace‐Beltrami operator for surface meshes is a fundamental building block for many (if not most) geometry processing algorithms. While Laplacians on triangle meshes have been researched intensively, yielding the cotangent discretization ...

A COMPUTER TECHNIQUE FOR ANALYZING RADIO‐TELEMETRY DATA

Wildlife Society Bulletin, 1980
An interactive computer system to analyze radio‐telemetry data has been developed and used on turkey observations. The program calculates home range by the convex polygon, capture radius, and non‐circular home range methods.

A new doubly discrete analogue of smoke ring flow and the real time simulation of fluid flow

, 2007
Modelling incompressible ideal fluids as a finite collection of vortex filaments is important in physics (super-fluidity, models for the onset of turbulence) as well as for numerical algorithms used in computer graphics for the real time simulation of ...

3D Reconstruction of Geometries for Urban Areas Supported by Computer Vision or Procedural Generations

Mathematics
This work presents a numerical mesh generation method for 3D urban scenes that could be easily converted into any 3D format, different from most implementations which are limited to specific environments in their applicability.
