Coordinate system
From Stunts Wiki
The topic of coordinate systems is a non-trivial matter to take into account with Stunts and tools designed for it. Usually, the difference between right-handed and left-handed coordinate systems is brought as an example of how these can differ, but in reality, very seldom we'll come across a left-handed coordinate system in 3D games and tools, as the standard is very strong on favouring its right-handed counterpart.
In contrast, viewport-oriented vs. cartography-oriented coordinates do deserve a closer look, as they're both very commonly used and offer their own convenience or justifications based on practical fact as well as philosophical reasons.
