💡 SoDirectionalLight — it's giving main character energy

okay bestie, welcome to the manual page for SoDirectionalLight, straight out of the SoDirectionalLight(3IV) manual 💅. grab a strawberry 🍓, sit down, and let's get into it.

✨ NAME ✨

SoDirectionalLight — the node that is a directional light source. like, it's literally a light that shines, no cap.

---

🧬 INHERITS FROM 🧬

the family tree goes crazy:

SoBase > SoFieldContainer > SoNode > SoLight > SoDirectionalLight

so yes, it inherited every single one of those genes 💖

🌈 DESCRIPTION 🌈

so this node defines a directional light source — meaning it illuminates along rays that are parallel to a given 3-dimensional vector. parallel rays, every single one, no drama, no diverging. iconic behavior honestly ✨

---

🎀 FIELDS 🎀

• SoSFVec3f direction — the illumination direction vector. that's the vibe, that's the direction it shines 💫

---

🛠️ METHODS 🛠️

• SoDirectionalLight() — creates a directional light source node with default settings. a fresh baby light, defaults and all 🍼
• static SoType getClassTypeId() — returns the type identifier for this class. iykyk 🪪

---

🔥 ACTION BEHAVIOR 🔥

SoGLRenderAction

Activates this light (if so specified) during traversal. All shape nodes that come after this light in the scene graph are illuminated by this light. The light's direction is affected by the current transformation.

so like — order matters bestie. if a shape shows up after this light, it gets lit. and the transformation is lowkey in charge of where the direction actually points. don't forget it 💀

---

📁 FILE FORMAT/DEFAULTS 📁

DirectionalLight {
    on         TRUE
    intensity  1
    color      1 1 1
    direction  0 0 -1
}

look at those defaults. pristine. immaculate. direction 0 0 -1 is the moment 🫶
