Mathematics function animation

Question

I am trying to animate a 2d parabola I created with Z math surface. Is there a way to animate the parabola without scripting?

Or is the best way to use animation nodes?

Geometry nodes solution

I just animated the factor.

Next GN solution

Here I animated A and B value.

result:

Classic solution with hooks

In Edit mode, select all vertices and press CTRL-H to create a hook modifier. Change the radius until you like the result. Then you can animate the empty-location and/or the radius.

And where's geometry nodes solution? :) – Markus von Broady Jul 09 '21 at 08:37
ok....sorry....coming... – Chris Jul 09 '21 at 08:38
updated my answer :D – Chris Jul 09 '21 at 08:43
Great, since you're in it, now add two input values (constants) a and b, and make the particle's z equal x*x/(a*a) + y*y/(b*b), then animate a and b with a driver – Markus von Broady Jul 09 '21 at 09:02
i am not that rich. I have no driver. I drive myself – Chris Jul 09 '21 at 09:14
oh man...don't know why i did this.... – Chris Jul 09 '21 at 09:23

Very nice!!! – Markus von Broady Jul 09 '21 at 09:41
ditto, please consider elevating nodes answer to top spot. Re hook: Be an interesting problem for the mathematicians to construct the equation of new parabola formed by hooks translation. Off to test Inverse square falloff. – batFINGER Jul 09 '21 at 10:06
@batFINGER: done – Chris Jul 09 '21 at 10:34
