Populated Surface With Even Distribted Circles

i am tryint to do a populated surface with even distribted circles. the size of the circle would be controled by their distances and other parameters, I already have the pattern build in Grasshopper but it is only 2D any not related to any surface. does anyone know how to make them follow some certain grid extracted by a surface? or how to naturally flow them along a certain surface? --THANK YOU!!

Hi Lilas,

you could try the [Surface Frames] component to create a rectangular grid. This automatically gives you surface tangent planes which can you can use to orient the circles.

Another option would be to map each individual circle onto the Surface UV space, then use Evaluate Surface to get the point and normal vector at that location. This approach will allow you to map any distribution of circles onto a surface, not just a rectangular one.
For this one you could create a plane surface underneath your 2D distribution, project all the circle centers to this plane surface, then use the resulting UV coordinates to evaluate the other surface. All you have to do is make sure the two surfaces have the same UV domain.
