Code/HumanoidRetargeter/Core/Formats/Mmd/Bullet/LinearMath/UShortVector3.cs

A small value type representing a 3-component vector of ushorts used by the Bullet physics port. It provides fields X,Y,Z, element access via an indexer, and Min/Max methods that clamp each component to the minimum or maximum with another UShortVector3 passed by ref.
