Hi
First, yes it is the vector OF rotation, sorry for the mistake...
And when I speak about normalizing, I'm just thinking of making a
vector.normalize()... with that operation, length of the vector will be 1,
even if the vector is close to 0 0 0...
I just want to use this vector to set the rotation vector of the Quat...
To be more clear : I have a Quat with a rotation vector which is very very
little... I ask if normalizing this vector will make a difference ? and why
?
Thanks,
Regards,
Vincent
