Geometry Nodes animation along normals

[titanuum]

Hi. I have a setup like this:

and I’m looking for a way to animate red elements along normals using e.g. noise texture. Any idea?

Probably easies solution would be using raycast and with attribute statistic node find shortest distances to offset the sphere. For more accurate results (to remove stepping if sphere is low resolution) you can use circles with high resolution and use it shortest distances to offset your sphere [image]

Maybe this thread will help

One more screenshot to clarify what I’m looking for. In this setup I can animate the red planes using noise texture along ONLY x/y/z axis. The question is: how to animate the red planes along its normals or sphere normals (the sphere would be surrounded with animated planes?

You can scale the captured normal using the noise as scale input and use the result as position offset.

Hope it helps.

Perfect! This is exactly what I was looking for. Thanks!

In my search for a way to scale the squares I found another node that also works:

Any idea how to make the squares get a little smaller as move away from the sphere?
