This document discusses rigging a 3D humanoid model in the software programs Blender and Unity. It begins by covering the creator's background in 3D development. It then explains the full body scanning process and various scanning technologies on the market. The document defines rigging as combining a 3D body surface from a scanner with bones provided by additional software to create an animated model. It provides details on the typical bone structure needed for humanoid rigging in Unity and demonstrates aspects of the rigging and animation process in Blender and Unity.
