Definition - What does Polygon Mesh mean?
A polygon mesh is a collection of edges, faces and connecting points that is used to provide a polygon model for 3-D modeling and computer animation. Its geometric makeup can be stored in order to facilitate various kinds of simulation of three-dimensional renderings.
Techopedia explains Polygon Mesh
In a polygon mesh, each surface joins together through its boundaries and common edges. One example is a three-dimensional sphere made up of identical faces, like a soccer ball in which the faces themselves can be flat or curved. More complex polygon meshes render people, animals, and other complex shapes. Computer engineers use specific digital tools to build and store these models for animation.
