I want to use my method to calculate the tangent and weight of the animation curve.
But I ran into a problem. I can’t know how the vector base of the coordinate system of the TimeLine panel is defined. In the 3D coordinate system, x=1 cm, y=1cm, z=1cm, but in the TimeLine panel, x= 1Frame ?1 second, y =1 cm?1%? or 1 Degree.
Thanks for any help!
