A polygon mesh or Unstructured Grid is a ''collection of vertices and Polygon s'' that define the shape of an Polyhedral object in 3D Computer Graphics . Meshes usually consists of Triangle s, Quadrilateral s or other simple convex polygons, since this simplifies Rendering , but they can also contain objects made of general polygons with optional holes. Examples of internal representations of an Unstructured Grid :
The choice of the data structure is governed by the application: it's easier to deal with triangles than general polygons, especially in Computational Geometry . For optimized algorithms it is necessary to have a fast access to topological information such as edges or neighboring faces; this requires more complex structures such as the winged-edge representation.
