I was reading a tutorial on inverse kinematics and i stumbled across CFrame:FromAxisAngle.
I read the wiki but sadly im not clearly informed on its purpose.
i was wondering if someone knows what this two functions do and how to use them and if possible explain it with visuals please and thank you.

CFrame.fromAxisAngle(Vector3 v,number r) lets you construct a CFrame rotated r radians around an axis based on the unit vector v, or in another way, a direction vector, so say you enter Vector3.new(0,1,0), this will be the Y axis, since that vector is looking upwards, and if you enter Vector3 Vector3.new(1,0,0), it will be considered the X axis, because the vector is oriented towards the right.
I made a quick example by modifying the orientation of a Part through its CFrame:
local part = script.Parent -- referencing the Part
part.CFrame = part.CFrame * CFrame.fromAxisAngle(Vector3.new(0,1,0),math.pi/3) -- math.pi/3 is 60 degrees, you could use math.rad(angle in degrees), if you are not familiar with radians.
This script will rotate it 60 degrees around the Y axis, example:
This is the part before being rotated:
After applying the rotation:
For CFrame:ToAxisAngle(), here’s a link to another forum thread:
Hopefully you’ve understood.
