Is there a way to reliably create a zebra/tiger stripe sort of pattern with nodes?
I'm hoping to apply the principle to the back of a cello

$\begingroup$ This can be easily achieved with a Wave texture $\endgroup$– Duarte Farrajota Ramos ♦Commented Apr 20, 2020 at 11:09

$\begingroup$ In what manner though? I am having a hard time replicating the branching that the lines have. I did some research and apparently a Gabor Texture can do this. $\endgroup$– Bobo_The_ImpCommented Apr 20, 2020 at 15:04

$\begingroup$ @DuarteFarrajotaRamos Hmm ... I didn't get even closer with any of blender's texture ... any deeper explanation or direction about this black&white reference? OSL Gabor Texture goes that direction, but without chance to get spiky ends. Thank you $\endgroup$– vkliduCommented May 25, 2021 at 17:21

A vaguely similar pattern could procedurally be achieved with a Wave texture. Is it physically accurate? No. Is it quick and dirty? Hell yes
Set it to Rings mode and stretch it in one direction using a Texture Mapping node (here in this example the $Z$ axis).
Adjust the Detail to a low-ish value, and the distortion to a high value to your taste.
Lastly run it through a Color Ramp node set to Constant interpolation.
Behold, my potato zebruh with a fake pattern.

1$\begingroup$ I love potato zebruh ... anyway that is what I called "far from b/w reference" :) Good tray :) $\endgroup$– vkliduCommented May 25, 2021 at 18:10
