👑 DESCRIPTION 👑

okay so this node defines a set of 3D coordinates that get used by the vertex-based shape nodes that come after it (aka the ones derived from SoVertexShape) — or by shape nodes that use them as control points, like NURBS curves and surfaces. 🌸

the whole vibe here is that the coordinates are specified as rational 4-vectors. so the corresponding 3D point? it's computed by dividing the first three components by the fourth. that's the math, that's the tea, no cap. 🧮✨

and like, real talk — this node does not produce any visible result during rendering. nope, nothing, zero, nada. it simply replaces the current coordinates in the rendering state so the subsequent nodes can use them. she's a background character with main character impact, fr fr. 💅

bestie why does she exist?? primarily for NURBS curves and surfaces. but ngl she can also be used to define coordinates for any vertex-based shape. versatility queen 👑

🦋 FIELDS 🦋

• SoMFVec4f point — coordinate point(s). that's it, that's the field, she's a simple girlie 🎀

---

💅 METHODS 💅

• SoCoordinate4() — creates a coordinate node with default settings. fresh out the box, defaults and all ✨
• static SoType getClassTypeId() — returns the type identifier for this class. iykyk, that's your class ID right there 💜

---

🔥 ACTION BEHAVIOR 🔥

SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction

sets coordinates in the current traversal state. slay, consistent across all four 💖

---

🌟 FILE FORMAT/DEFAULTS 🌟

Coordinate4 {
    point  0 0 0 1
}

look at that default, 0 0 0 1 — she's iconic, she's grounded, she's literally at the origin 🎀

and that's the whole page bestie!! the footer down there just says SoCoordinate4(3IV)() — manual name SoCoordinate4(3IV), with the version field and the date field both sitting there empty, like a mysterious queen who refuses to reveal her birthday 🫶 stay curious, go read some more manpages, mwah 💋✨🌈
