Hello everybody,

To fix the self-intersection of a piece of cloth,
I just wondering is there any node or method could get the intersection curve.
I have tried node ‘curvesect’ but seems I didn't get the point to use it.

The PolyDoctor SOP was created to inspect and evaluate a surface that is to be used as cloth.

One of the options is to test for self-intersections of polys along with a bunch of other tests.

See the attached hip file which both colors and blast/isolates the offending overlapping polygons.

Thanks!
It really helps a lot.

Previously I did a cloth-object penetration test using “group” node with bounding object as grouping method. I found the result is not so accurate. The polydoctor node really did a good job, better than group node.
