SONURBSPROFILE(3iv)

💖 SoNurbsProfile — the NURBS profile curve page, bestie edition 💖

okay so. we're in the SoNurbsProfile(3IV) manual page, and honestly? it's a short one, so grab your strawberry drink 🍓 and let's go, because this little node is doing a LOT of heavy lifting in the curve department.

🌸 NAME 🌸

SoNurbsProfile — NURBS profile curve. that's it. that's the whole name. iconic brevity, no notes. ✨

---

🦋 INHERITS FROM 🦋

the whole family tree, and yes she comes from a long line of distinguished ancestors:

SoBase > SoFieldContainer > SoNode > SoProfile > SoNurbsProfile

so like… she's a SoProfile, which is a SoNode, which is a SoFieldContainer, which is a SoBase. main character lineage fr fr 💅

✨ SYNOPSIS ✨

first things first, you gotta include her:

👑 DESCRIPTION 👑

okay so here's the tea ☕ — this node specifies a NURBS curve that gets used as a profile. and the way it works is basically the same way a standard SoNurbsCurve works… except (and this is the key part, don't skip it 🫶) the control points aren't just handed to you directly — they're constructed from the current set of profile coordinates, using the index field. that's the whole vibe. that's the plot. 🌟

---

💜 FIELDS 💜

• knotVector (SoMFFloat) — the knot vector for the NURBS curve. and bestie, it must be a list of non-decreasing floating point values. non-decreasing. we do not go backwards in this house. 📉❌📈✅

---

🎀 METHODS 🎀

• SoNurbsProfile() — creates a NURBS profile curve node with default settings. fresh out the box, defaults intact, ready to slay. ✨
• static SoType getClassTypeId() — returns the type identifier for this class. it's giving "who am I" but in a bureaucratic sense. 🪪

---

🔥 ACTION BEHAVIOR 🔥

the actions below all do the same cute little thing:

• SoGLRenderAction
• SoCallbackAction
• SoRayPickAction

they all add a profile to the current traversal state. that's the move. that's the whole move. 💃

---

🌸 FILE FORMAT/DEFAULTS 🌸

here's what she looks like written down, defaults and all, verbatim, no cap:

NurbsProfile {
    index       0
    linkage     START_FIRST
    knotVector  0
}

---

🌈 SEE ALSO 🌈

go read these next, they're all in the same friend group:

• SoLinearProfile
• SoNurbsCurve
• SoProfileCoordinate2
• SoProfileCoordinate3

---

quick reminder bestie: knotVector has to be non-decreasing. that's a real requirement, not a suggestion. don't come for me when it breaks. 😭

---

okay that's the whole page!! it came from the SoNurbsProfile(3IV) source/version, and the footer date area was lowkey empty (SoNurbsProfile(3IV)()), so like… timeless, no date, forever iconic. 💖✨ go build something gorgeous with your NURBS, ily, bye 🫶🎀🦋
