I'm kind of new to Houdini, for about 4 months, and coming from Blender & C4D, I'm really amazed with the possibilities of the soft.
That being said, I'm searching since a few weeks for a solution to make a specific shape of fibers heap, or clusters, as it can be found in an iris, aka the colarettes and the radial furrows.
Actually, describing it is kind of tricky, so if we take these pictures :
My idea was to create two layers of fibers :
- The first (bottom one), is made from a line/copy to points of a circle, and applying some noise individually to each copied line, through a for each loop, allowing me to randomize the noise on each unique fiber :
- The second layer, that I can't manage how to do, should be on the top, and should make these kind of clusters that I talked about, more or less the red surface on the next image (colarettes & radial furrows) :
I don't know how to do this second top layer, and I've tried (and desperately failed!) all the solutions I could imagine :
- via a volume, with noise, and a volume trail
- via a popnet, where particles are emitted from my center circle, along normals pointed away, and with a pop collision detect attached to a sphere. But while my particles slide around the sphere, the trails don't end up with the desired shape, at the exit of the sphere
- via find shortest path sop, with hole on my initial geometry, but doesn't work neither…
My feeling is that the particle solution could be the best, but don't really know how.
I'm kind of stuck here, I'm sure because of my software's knowledge limitations, as I'm new to H, and thought maybe you could give me some directions to do this (even if they are different from my initial setup)…
Thx in advance (and sorry for my possible mistakes, english isn't my mother language).

, as I have very actively searched for a solution on youtube, Vimeo, oddforce and here, since a certain amount of time !)
