Bone01.x1[MTXSource, MTXTarget] := Sqrt((x1x2)/(x1+x2))-Sqrt((x1x1/x2)+(x2x2/x1));
Bone01.y1[MTXSource, MTXTarget] := Sqrt((y1+(x1-z1)(x2-z2)/((x2y1)+(z2y1))/(y2-y1));
Bone01.z1[MTXSource, MTXTarget] := Sqrt((z2Sin(z1+z2))-(z1(Cos(z1+z2)/(x2*x1)));
Woaw the central bone is great effectively movement to target.
If you want to other bone in human model that have 26 bones system.
I have controller bone module calculation more this…
