Polylidar - Polygons From Triangular Meshes [PDF]
IEEE Robotics and Automation Letters, 2020 This paper presents Polylidar, an efficient algorithm to extract non-convex polygons from 2D point sets, including interior holes. Plane segmented point clouds can be input into Polylidar to extract their polygonal counterpart, thereby reducing map size and improving visualization.

A Surface Division Method of Parts Mesh Model for On-Machine Inspection
IEEE Access, 2020 As a general 3D model data format, triangular mesh model has been widely used in mechanical engineering to realize the function of transmitting data between different CAD software, but during the transmission, a large amount of geometric and topological ...

Unsupervised Machine Learning for Improved Delaunay Triangulation
Journal of Marine Science and Engineering, 2021 Physical oceanography models rely heavily on grid discretization. It is known that unstructured grids perform well in dealing with boundary fitting problems in complex nearshore regions.

MORPHING OF TRIANGULAR MESHES IN SHAPE SPACE [PDF]
International Journal of Shape Modeling, 2010 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 $\mathcal{S}$. For triangulated 3D polygons, we prove that interpolating linearly in this shape space corresponds to the most isometric morph in $\mathbb{R}^3 ...

Parametric Blending of Triangular Meshes [PDF]
Symmetry, 2018 We present a new method for constructing a parametric blending surface that smoothly connects two triangular meshes. A user selects a subregion on each triangular mesh. The local parameterizations of two selected regions are found by using geodesic polar coordinates, and a base surface on each triangular mesh is constructed by two boundary curves on ...

On the resolution of triangular meshes
Journal of Advances in Modeling Earth Systems, 2022 AbstractIt is generally agreed that the resolution of a regular quadrilateral mesh is the side length of quadrilateral cells. There is less agreement on the resolution of triangular meshes, exacerbated by the fact that the numbers of edges or cells on triangular meshes are approximately three or two times larger than that of vertices.

Computing geodesics on triangular meshes [PDF]
Computers & Graphics, 2005 We present a new algorithm to compute a geodesic path over a triangulated surface. Based on Sethian's Fast Marching Method and Polthier's straightest geodesics theory, we are able to generate an iterative process to obtain a good discrete geodesic approximation. It can handle both convex and non-convex surfaces.

Anisotropic Mesh Adaptation for Image Representation [PDF]
, 2016 Triangular meshes have gained much interest in image representation and have been widely used in image processing. This paper introduces a framework of anisotropic mesh adaptation (AMA) methods to image representation and proposes a GPRAMA method that is
