Spring.UnitPieceTurnVec(UnitID, normedVecX, normedVecY, norm

The idea was/is to avoid the whole vector to rad dance (with speed according to turn length) by getting a vector, and beeing able to turn a piece directly into that direction in one smooth movement.
+ Less Engine Calls
+Can use the output of most vector returning lua functions. (dont rememer if it has to be normalized)

Yeah, it will results in troubles as spring doesent use quaternions, which makes this basically three euler rotations.

If you had two vectors (shoulder joint to current IK position (x1,x2,x3), joint to desired IK position (x2,y2,z2), you can calculate the rotation matrix between these two vectors with http://sourceforge.net/p/advants/kaena/ ... mVectors.h

ever thought of doing all rotations with quaternions in lua and then convert the results to Tayler-Brian angles used in spring?

You can build a rotation matrix to rotate about any arbitrary axis like this:

How exactly did you derived that may I ask?

No, you smart ass, that not what I meant. What I mean is to show us your calculations, if you didn't calculate the equation and merely copy it, then tell us where, whom, name of it is.

you probably could have found that in less time than it took to post and complain

Or he could not be a smart ass,and just tell me the name of it, instead of posting a wiki link to linear algebra.
