Thanks - that didn't work and after playing around with cut list / comb list to see how the lines connect I think it's because it draws the line from the first point and then up onto the next row - which makes sense. Perhaps I need to think about this differently.
I'm using @ Bodysoulspirit's Get Object Vertices node along with Make Points along Spline & Make Line Strip Object / Make Lines Object on a Sphere. I would like to remove the vertical line that runs through it as I want to achieve this look of concentric rings but on a 3d object (wireframe shader doesn't give the aesthetic I'm after)
Is it because the lines start and end in the same place? Perhaps there's another way of achieving this? Where there are concentric rings around the 3d shape to achieve a geometric look.
Is it possible to generate frequencies from an image sequence, for example the luminance or the colour? I'm interesting in creating a generative audio piece.
