Transfering attributes one by one...

[Christian S]

Hi,

 

I'm trying to transfer a point attribute to a grid but not all at once. I want the attribute to stack just like using a 10% brush in Photoshop multiple time at the same position. In depth :

 

I have a grid and also some scattered points on it. I want to take scatter point no.1 and transfers 10% of it's attribute to the grid. Repeat with point no.2 but using the new geometry so if point no.1 and no.2 are intersecting it will give 20% at the intersection.

 

I tried many solutions... AttribTransfer alone doesn't seem to support this. I tried making a ForEach SOP without succes either. Finally, I'm pretty sure there is a way of doing this with a VopSop and some point cloud nodes but I'm lost.

 

If anyone would point me in the right direction i'd be more than happy

 

The image so the result I would live to get.

 

Thanks!

There might well be smarter ways to do it, but here's with foreach and attribute transfer.

Here's one possible approach using vex (PointWrangle SOP).

This is quite awesome Mario! I never used Vex code but i'll look at your example until I figure everything out. Many thx!
