This repository's original aim was to be roughly analogous to the library Cam Z-Up for Processing, except that it worked in conjunction with the Unity game development engine.
Because it has had to walk a line between independence from -- and compatibility with -- Unity's C# Scripting API, certain naming conventions were followed to avoid collisions. For example, Quat is short for Quaternion; ClrGradient is elongated from Gradient; and so on.
For anyone transitioning from Unity to Godot due to recent developments, see the GodotWork repository, still in development.
