What RotateTowards's maxMagnitudeDelta about?

I am using at unity docs, Vector3.RotateTowards for rotate my character and go to target location.

and very headache about what is maxMagnitudeDelta's float value mean? radian? or angle?

if maxMagnitudeDelta = 1.0f, How this affect about what amount?

Thanks.

 

http://docs.unity3d.com/ScriptReference/Vector3.RotateTowards.html

magnitude delta is about changing the length of the vector if they dont match

 

Just FYI, the linked page doesn't say jack about the magnitude delta, just the radian delta.

 

There's a little better explanation here:
https://docs.unity3d.com/400/Documentation/ScriptReference/Vector3.RotateTowards.html

It sounds like it kind of a clamp for speed change.

 

Please see
https://docs.unity3d.com/351/Documentation/ScriptReference/Vector3.RotateTowards.html
and
https://docs.unity3d.com/410/Documentation/ScriptReference/Vector3.RotateTowards.html
And realise that 3 years ago when this post was made, the docs were different, and continue to change all the time, and necroposting helps noone.
