UV canvas is a 2D representation of a 3D model that projects textures on top of meshes. It uses U and V axes, equal to X and Y to plot where the pieces go. A 3D mesh is unwrapped to form a 2D net, then placed onto the UV canvas. UV mapping is like skinning the model and cutting it into pieces so that they can all be laid out on a flat surface, ready for texturing.

Texturing and Shaders
Textures and shaders are 2D digital maps that make up how a digital 3D model looks. Textures are image files that cover a model’s surface to create colour, texture and patterns, using the UV map of the model. Textures can be created using digital painting software like Photoshop or by using photographs to fill the UV map. Roughness, highlights and translucent effects can be created using multiple texturing maps such as diffuse, specular and bump maps.
Shaders control how the surface of the model interacts with light, without which, the model would be nothing more than invisible points in a 3D plane. Different shaders can be used to allow different types of surfaces to appear realistic.

Rigging converts the 3D model for a stagnant statue into a maneuverable figure. The model is rigged with mechanisms that can be controlled and programmed to allow the model to perform actions. Rigging methods allowing the application of these actions include: joint rigging, facial rigging, forward and inverse kinematics, blend shapes, deformers, control curves, skinning, and weight painting. Joint rigging enables riggers to create a “skeleton” for the model, transforming it into a puppet.
