Duplicate thread !!!

Grill like a photo

Hello here is the script. It uses a grid of closed polylines (it could be curves). These curves are then centered and inversed via a graph mapper. It is more versatile than the equation of inversion. [image] The second part remove outer curves and curves with a too big area. [image] And then image is created via classical Image sampler. The surface is done via mesh because it is faster than loft but it is quite long. [image] Happy experimentations grid inversion.gh (627.4 KB)

Thank you so much.

in the expression: v*r (inverted v) 2/1, how to you do the inverted v?
Can’t find it anywhere?

I think it’s better to ask the same question in the other thread.
This duplicate thread makes things complicated.

It is simple math to.invert something relative to a circle of radius r centered on 0. V is a vector and l the length from center to 0.
