A UV MAP SHORT EXPLAINED:

• The texturing process is a way to map a 2D image texture to 3D models. For this process a so called “UV-map” is used.
• The letters "U" and "V" denote the axes of the 2D texture because "X", "Y" and "Z" are already used to denote the axes of the 3D object in model space1

A UV-Map can be created by “unwrapping” the models polygon mesh. 

UV coordinates (also known as texture coordinates) can be generated for each vertex in the mesh.

What is a 3D Object made of? 

Such a polygon mesh 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 (triangle mesh), quadrilaterals (quads) or other simple convex polygons²

Dodecahedron UV Map Example

Dodecahedron is made out of verteces, lines and surfaces

By unfolding/unwrapping the Dodi the UV Map is created

The UV Map can then be texturized and re-wraped onto the 3D object
