Hello I am a student studying Unity. First of all, I am sorry that I am not fluent in English. I found a way to find the inslope and outslope of Euler rotation in the Animation Editor and how to draw a Bezier curve in the editor. However, in the case of Quaternion, I don't know what mathematical formula to calculate inSlope and outSlope. What I found is using the SQUAD function. Are the auxiliary vectors calculated by the Squad function inslope and outslope correct?
