This is pretty much essential for mouse-based camera control in 3D simulations, especially when combined with a "warp cursor to center of window" feature. Typically, the cursor will be confined to the window and warped to the center of the window at the start of every frame. This allows for all mouse movements to be treated as delta offsets from the center of the window, and these can typically be passed directly into camera handling functions. -- Mark Raynsford | https://www.io7m.com
