Skinned meshes in Unity3D
A skinned mesh is a set of polygons whose positions and rotations are computed
based on the positions of the various transforms in a hierarchy. Instead of each
GameObject in the hierarchy have its own mesh, a single set of polygons is shared
across a number of transforms. This results in a single mesh that we call a skin be-
cause it envelops the transforms in a skin-like structure. It turns out that this type of
mesh is great for in-game characters because it moves like skin.
