Question Regarding Cubic Interpolation in Timelines

Our team is doing research with a neuroscience lab @uwaterloo, and we were wondering if there was any additional documentation regarding how the engine calculates the Automatic Interpolation for Timeline curves.

Any help would be greatly appreciated, thanks :smiley:

Specifically, we are looking for the actual calculation source code:

Is this equivalent to ->

Specifically, if UE4.15.3 uses C++ 14 Standard, does that imply that the Cubic Spline is calculated according to what method.
