So, why are CalcHermite() and CalcSoftTangents() included if it is strongly advised to use GetTangents() instead?
What does GetTangents() actually do? Does it change the tangents on spline interpolated keys or just return the Left-Right Time and Value settings?
I'm trying to calculate continuous (considered over multiple keys) Hermite tangents to more closely match the input format (Poser's). First, I can't verify that Poser aninmation spline interpolation uses Hermite curves - but since Bezier and B-Spline control points are not necessarily on the curve, this is the only candidate so far. Second, I have no idea how Poser calculates tangents so as to be continuous - that is, if you change the value or time of a key, the complete curve across keys is recalculated. I can only suppose that this will be the case here as well.
Any information while I'm frustratingly experimenting would be appreciated.
