Recent versions of Blender do not generate any type of F-curve.
In particular, after inserting a key position image on the object, I would like to enter:
-for Xposition: f (t) = 8 * cos (t ^ 3)
-for Yposition: f (t) = 8 * sin (t ^ 3)
-for Zposition: f (t) = 0
which is impossible with an F-curve modifier, to create on the object a circular plane motion of radius 8 and accelerated
All that remains is Python.
1) A python script for this?
2) More generally, I'm looking for a tutorial elaborating a Python script to enter any type of mathematical function of a single variable, representing an F-curve related to any keyframe insertion.
Thank you for your help
