Avoiding self intersection when displace along N

[anbt 5]

I am trying to displace the mesh of a cloth along its normals with a PeakSOP but as there are a lot of wrinkles, it doesn't work as intended. Any idea how I can achieve the example bottom right?!

 

cheers

You can filter and "smooth" the direction(N) you use to "peak" your surface. pcopen-pcfilter will do that just fine.

in vex:

int handle = pcopen(0, "P", @P, ch("radius"), chi("max_points"));
@P = pcfilter(handle,"P");

You can do similar in Vop too.

There is a nice method using a ray SOP to detect and avoid intersections too, it's explained in this tutorial:
