Difference between copying to points on polygons and not

Hi!

Why do these two methods produce different orientations on the copied geo? As far as I can tell, there is no difference in the attributes present on the points when they are part of the circle and when they are not.

Directly from Circle:


Points Extracted:


Thanks!

I'm guessing the circle has normals by default so it affects the copy-to-point. If you use the extractAllPoints, it probably removes the @N so you get a default orientation for all copies.

From what I can see in the geometry spreadsheet, there are no normals specified on the circle's points, vertices, or primitives... Are they implicitly created and read in the process of copying to points?

yes, many geometry operators use implicitly computed normals from polygons when they are not explicitly defined by an attribute
