 **imGuIZMO.quat** is a [**ImGui**](https://github.com/ocornut/imgui) widget: like a trackball it provides a way to rotate models, lights, or objects with mouse, and graphically visualize their position in space, also around any single axis (*Shift/Ctrl/Alt/Super*). It uses **quaternions** algebra, internally, to manage rotations, but offers the possibility also to interfacing with **vec3**, **vec4** or **mat4x4** (rotation)
 
 With **imGuIZMO.quat** you can manipulate an object **with only 4 code lines!**     *(read below)*
