[Bf-animsys] Pole angle and IK constraints ...

[Gaia]

Hi;

We can define a Pole Target and a Pole Angle when we add an IK 
constraint to a bone. However i believe that the pole angle is actually 
defined as follows:

/"the pole angle is the angle between the bone's local x axis and the 
connection line between the pole target and the bone"/

If this is true, then we can calculate the pole angle. here is an 
unfinished python example for how it could be done (probably it can be 
done better):

So am i correct ? If not can you please give me a reason and an example 
for a situation where i WANT to set the pole angle manually ?

cheers,
Gaia
