Vellum sliding constraint on itself

[kmdani]

Hi! I'm trying to use the new Sliding constraint in vellum (houdini 18). I had good result when I tried to constrain my geometries to a collider geo. (Using the Attach the geometry or the Stich constraint node.)

But when I'm trying to "Sliding constraint"  together my geometries, I can't make it work.

So basically, I want my active vellum objects "sliding constrain" together many shells of geometries.

 

Any ideas?

(Not too much info in the docs sadly. https://www.sidefx.com/docs/houdini/vellum/slidingconstraints.html)

why don't you just dissect the sliding_examples from here ?

Thanks, I'll check it!

Okay, so as far as I figured it out: when you have a tetrahedra/solidconformed object that you want to apply sliding constraint on, you need to turn on the "Add Surface triangles" option in the solidconform node. After that, you can have your point group and the target primitive group that you want to apply it to.

 

It is a little strange from me, that the "From Connectivity" option is not available with the "Use Closest Location on primitive" On. Because if I want some random points - sliding -  constrained to the closest surface (that is not part of the same shell), and also want to have the sliding constraint, it is pretty hard to do.

I can have the glue constraint and just turn on the From Conncectivity, but that won't have the sliding...
