8 NodeGroups!! and 2 BONUS simplify deformers that help in performance!
I
have created these advanced deformers to use in geometry nodes that
work the same as traditional modifiers and, in some cases, are better
than these. I recreate these modifiers with Geometry Nodes to be able to use them in my daily work in an easy way with Geometry Nodes.

Twist Deformer:

Taper Deformer:

Stretch Deformer:

Shrink Warp Deformer:

One of the advanced functions that allow these nodes is to use custom geometry to define deformation falloffs.
