Deformation of the grid with the falloff I am trying to model a deformation of a grid with interpollation in the Animation Node, but as you can see I didn't can to use FALLOFF for to get a grid according with 1/r². Can someone help me? is it possible to use an configuration(Falloff) in AN to deform the grid according to the equation (-1/r²)?

Equation [-1/(x²+y²)]

Falloffs in Animation Nodes are mostly hard-coded, that is, you need to write cython/python code to create a custom falloff. So it is much easier to compute the effect you are after manually. A simple implementation of grid deformation is as follows:



Want to transform it based on an empty? Simply subtract the location of the empty from the x and y of your equations:



Want to scale it? Similarly multiply the scale of the empty to the x and y of the equation.
