A polygon mesh or unstructured grid is a collection of vertices, edges and faces that defines the shape of a polyhedral object in 3D computer graphics and solid modeling. The faces usually consist of triangles, quadrilaterals or other simple convex polygons, since this simplifies rendering, but may also be composed of more general concave polygons, or polygons with holes. The study of polygon meshes is a large sub-field of computer graphics and geometric modeling.

  • A polygon mesh or unstructured grid is a collection of vertices, edges and faces that defines the shape of a polyhedral object in 3D computer graphics and solid modeling. The faces usually consist of triangles, quadrilaterals or other simple convex polygons, since this simplifies rendering, but may also be composed of more general concave polygons, or polygons with holes. The study of polygon meshes is a large sub-field of computer graphics and geometric modeling. Different representations of polygon meshes are used for different applications and goals. The variety of operations performed on meshes may include Boolean logic, smoothing, simplification, and many others. Network representations, "streaming" and "progressive" meshes, are used to transmit polygon meshes over a network. Volumetric meshes are distinct from polygon meshes in that they explicitly represent both the surface and volume of a structure, while polygon meshes only explicitly represent the surface (the volume is implicit). As polygonal meshes are extensively used in computer graphics, algorithms also exist for ray tracing, collision detection, and rigid-body dynamics of polygon meshes.
  • Zur Speicherung von Polygonen und polygonalen Netzen, wie sie in der 3D-Computergrafik verwendet werden, gibt es eine Reihe bekannter Datenstrukturen. Die bekanntesten Strukturen sind die Knotenliste, Kantenliste, Winged Edge und die doppelt verkettete Kantenliste (doubly connected halfedge list).
  • Un Mesh est un objet tridimensionnel constitué de polygones sous forme de fil de fer. Des outils de modélisation graphique tels que Blender ou 3D Studio Max permettent de réaliser ces objets filaires.
  • Uma malha poligonal é uma coleção de faces (onde cada uma é um conjunto de vértices) que definem um objeto tridimensional nos campos da computação gráfica e da modelagem tridimensional. As faces geralmente são constituídas de triângulos ou quadriláteros, umas vez que estas formas simplificam o processo de renderização, no entanto também podem ser compostas por formas geométricas complexas. O estudo das malhas poligonais é um grande sub-campo da computação gráfica e modelagem geométrica. Diferentes representações de malhas poligonais são utilizadas para diferentes aplicações e propósitos. Devido a grande importância deste assunto, atualmente existem algoritmos bem desenvolvidos para técnicas como ray tracing, detecção de colisão, etc.
  • Полигональная сетка — объект в трехмерной графике, представляющий собой совокупность вершин и полигонов, который определяет форму отображаемого многогранного объекта.
  • 多边形网格是三维计算机图形学中表示多面体形状的顶点与多边形的集合，它也叫作非结构网格。 这些网格通常由三角形、四边形或者其它的简单凸多边形组成，这样可以简化渲染过程。但是，网格也可以包括带有空洞的普通多边形组成的物体。 非结构网格内部表示的例子有： 一组顶点的简单列表，它们带有表示那些顶点组成多边形的信息列表；另外可能带有表示空洞的附加信息。 顶点列表 + 边界列表（一对索引信息）+ 连接边界的多边形列表 翼边数据结构 根据应用程序的不同所选择的数据结构也有所不同：三角形的处理要比普通多边形的处理更加简单，尤其是在计算几何中更是这样。对于优化的算法，可能需要快速访问边线或者相邻表面这样的拓扑信息，这样就需要如翼边表示这样更加复杂的结构。
