A ray whose position and direction are stabilized in a way similar to how gaze stabilization works in HoloLens.
The ray uses Anatolie Gavrulic's "DynamicExpDecay" filter to stabilize the ray this filter adjusts its smoothing factor based on the velocity of the filtered object
The formula is Y_smooted += ∆𝑌_𝑟 where 〖∆𝑌_𝑟=∆𝑌∗〖0.5〗^(∆𝑌/〖Halflife〗)
In code, LERP(signal, oldValue, POW(0.5, ABS(signal – oldValue) / hl)
