In the section, Inverse Kinetics in 2D of this article: http://freespace.virgin.net/hugo.elias/models/m_ik.htm
There is Vector R. How could I find this vector R? I know the length of the bone and its angle, how could I then calculate vector R in this example?
Thanks
Would it simply be taking the vector of the angle and returning v.y, -v.x?
