I've got two faces raycasting from theirs points against cube's geometry.

If there is a hit, then a whole face should inherit hit status, so left face with one point inside cube should return "1" (in Viewer output it is "1" for a point and "0" for a face in yellow framed area).

In order to do it, I should calculate total amount of hits on each casting face or mesh island.

With no luck I tried Transfer Attribute node and Attribute Statistics.

  • $\begingroup$ @quellenform, question was about accumulating points' "hit status" on a source polygon. So, Accumulate Field node solved this issue. $\endgroup$

Accumulate Field allows to collect data within specified geometry groups input - Group Index.

I want to get total amount of ray hits on each source face, so have to get proper indices first (Capture Attribute with face option) or Mesh Island ID for a whole separated geometry and plug it to Group Index.

You can accumulate not only points, but edges and faces as well, just make sure Group Index is valid.
