RFE for Polywire SOP

Perhaps there should be an option to use the input curve's normals?

AFAIK, presently, to do this, you need to enable the “Joint Upvector” option
and then enter the following 3 expressions for NX, NY, NZ:

point(“../pwInput”, $PT, “N”, 0)
point(“../pwInput”, $PT, “N”, 1)
point(“../pwInput”, $PT, “N”, 2)

Where “pwInput” is a Null SOP going into the Polywire SOP (to avoid clazy feedback/self-referencing).

It seems like this is what you'd normally want, so a toggle: “Use Wire Normals” might help.

What's wrong with just putting $NX,$NY,$NZ in the upvector parameter?

I havn't tried, but if what simon suggests works for you, you can just add it as a preset for the PolyWire SOP.

omg. haha! yes. nice. thx simon. I just RTFM:

The four numerical parameters support all the local variables of the Point operation, plus the LSYSTEM specific variables of $WIDTH, $SEGS, $DIV, $LAGE, $GEN, and $ARC.

the docs need an update; there's more than four “numerical” parms.
Change “the Point operation” to “the Point SOP”?

Indeed! It's tempting to set it as a “permanent default” but they're ticking timebombs. Just when you get used to them, they're gone with the next version of Houdini (or you give another user a script with an opadd - boom!).

btw i noticed an “LSYSTEM” option in the presets menu.. Interesting.
