[Opensim-users] Strange behavior of the llsittarget when the primitive is rotated 90? in X (Ferd Frederix)

[Leal Duarte]

Euler angles (or rotations) can be confusing.

< a,b,c> on our and sl convention means

rotate around Z by c;

then rotate the result around Y by b

then rotate the result around X by a

applied exactly by this order.

if you look your numbers considering this, it may make more sense
