3) High Poly Model
Although the order in which the High Poly and Low Poly models are created is interchangeable depending on the workflow (creating an extremely detailed model and removing detail from it, or creating a simple model and adding detail to it), it’s exact place in the workflow depends often on personal preference. As the name suggests, a High Poly model is created with a large amount of detail, which would be undesirable for use in a real-time rendering situation, but can be beneficial in several other ways, as explained below.
4) UV Mapping
UV mapping is one of the most important parts of the 3D workflow. It involves taking a 3D model that exists in 3D “XYZ coordinate” space, and unwrapping and unfolding it so that it sits perfectly in 2D “UV coordinate” space. The easiest way to think of this process is backwards origami. By unfolding the model and laying it flat, the 3D artist creates a 2D image that can be drawn on. Since every polygon, edge and vertex are laid out in this 2D space, each section of the image is also associated with a location in 3D space.
