void calculateHandAxisRotation(const MatrixF& handRotation, const F32& maxHandAxisRadius, Point2F& outRotation)
{
const VectorF& controllerUp = handRotation.getUpVector();
outRotation.x = controllerUp.x;
outRotation.y = controllerUp.y;
// Limit the axis angle to that given to us
if(outRotation.len() > maxHandAxisRadius)
{
outRotation.normalize(maxHandAxisRadius);
}
// Renormalize to the range of 0..1
if(maxHandAxisRadius != 0.0f)
{
outRotation /= maxHandAxisRadius;
}
