am i stupid? why is `gl_wireframe` somehow nowhere visible in the render properties shown in an Edit Properties LOP?

i’ve seen it done this way, i know i’ve done it myself in the past, but it’s like impossible to find in this mess of parameters. also, *why is it so fucking hard to show curves in the viewport without thickness*? why do i have to dig through this insane menu to do this?

i even tried adding the property as-is myself having memorized the name and it doesn’t fuckin work!

okay so after some digging, apparently this property has *never* been exposed by any menu and can’t be assigned at all unless you do it manually. so if you want guide curves in solaris, and you don’t want them rendered as big obnoxious ribbons, you have to use an Edit Properties LOP, manually drag an integer property from the USD Proprties list, and name it `primvars:houdini:gl_wireframe`, OR you have to do it via a wrangle: “` usd_addprimvar(0, s@primpath, “houdini:gl_wireframe”, “bool”); usd_setprimvar(0, s@primpath, “houdini:gl_wireframe”, 1); “`
brilliant UX

i find it really hard to believe this hasn’t been an issue for any other solaris users before. are guide curves really not used by anyone?

kuwahara is a cool trick but it does date from 1976, bilateral filters are a more controllable and better behaved way to filter while avoiding edges… here’s one i use a lot in comp and just translated from glsl to opencl

it works ok on bacon but i do feel like it could be improved 🤔 it’s the kind of thing that works better in log than linear and the threshold control might be better if it was a hard cutoff so colours past a certain distance are ignored, instead of this drastic pow() curve thing i’m doing

Sure thing. I’ll upload a file today when I get back.

@.goldfarb. Here you go. 2 days late . Added a few more controls to it. There’s still a few things I want to fix and add. Big thing for me – figuring out how to set a LookAt constraint that allows you to move the Driven while also obeying the orientation toward the Up so then it’ll aim/rotate from the correct pivot.
