SoPointLight(3)

🎀 NAME 🎀

okay so welcome to SoPointLight(3) bestie 💖 — this one is a node type for light sources. that's the whole vibe, that's the assignment. a light. that's a point. iconic.

✨ SYNOPSIS ✨

first things first, you gotta pull in the header or nothing happens, fr fr:

#include <Inventor/nodes/SoPointLight.h>

Inherits SoLight.

Inherited by SoPointLightManip.

so like, SoPointLight is the child of SoLight, and SoPointLightManip is the child of this. it's giving family tree 🌳

and initClass sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. no cap, it's the lil setup ritual ✨

two little notes from the og page, bestie:

💡 Detailed Description 💡

so, the SoPointLight class is a node type for light sources. that's the name, that's the game.

point lights emit light equally in all directions from a specified 3D location. like a lil sparkly orb of glow in your scene, radiating in every direction at once. so main character of it ✨

also — and this is important bestie — see the documentation of the parent class for important information regarding light sources in general. don't skip it, it's required reading, iykyk 🫶

FILE FORMAT/DEFAULTS:

PointLight {
    on TRUE
    intensity 1
    color 1 1 1
    location 0 0 1
}

look at those defaults being all cozy. on is TRUE, intensity is 1, color is 1 1 1 (that's white, bestie, pure white 💀✨), and location is 0 0 1.

🛠️ Constructor & Destructor Documentation 🛠️

🎀 SoPointLight::SoPointLight (void )

Constructor. that's it. that's the note. it makes the thing 💅

🦋 SoPointLight::~SoPointLight () [protected], [virtual]

Destructor. protected and virtual, so she's not for just anyone to call. she cleans up when the vibe is over 😭

💖 MEMBER FUNCTION DOCUMENTATION 💖

okay bestie, this is the part where we meet all the lil methods that make this light glow. no cap, every single one is here, don't skip. 🫶

---

✨ SoType SoPointLight::getClassTypeId (void ) — [static] ✨

the ✨static✨ baddie of the family. it hands you back the SoType object that's tied to objects of this exact class. that's it, that's the whole vibe. 💅

---

🦋 SoType SoPointLight::getTypeId (void ) const — [virtual] 🦋

this one gives you the type ID of any object that comes from a class inheriting SoBase. it's the whole reason runtime type checking works, and it's how the "downward" casting magic happens. lowkey essential, fr fr. 🔥

• Reimplemented from SoLight.
• Reimplemented in SoPointLightManip.

---

🎀 const SoFieldData ** SoPointLight::getFieldDataPtr (void ) — [static], [protected] 🎀

sooo this API member is considered internal to the library, because it's not likely to be of interest to the application programmer. so like… if you're just vibing in app-land, this isn't for you bestie, no hard feelings. 🙈

it returns the SoFieldData class that holds all the info about the fields in this node. that's the whole thing. 💜

---

🌸 const SoFieldData * SoPointLight::getFieldData (void ) const — [protected], [virtual] 🌸

this cutie returns a pointer to the class-wide field data storage object for this particular instance. and heads up: if there are no fields present, it returns NULL. not a vibe, but that's the deal. 😭

• Reimplemented from SoLight.
• Reimplemented in SoPointLightManip.

---

👑 void SoPointLight::GLRender (SoGLRenderAction * action) — [virtual] 👑

this is the action method for the SoGLRenderAction, and she's kind of the main character ngl. ✨

this gets called during rendering traversals. any node that influences the rendering state in literally any way, or that wants to yeet geometry primitives at OpenGL, overrides this method. iconic behavior honestly. 🔥

• Reimplemented from SoNode.
• Reimplemented in SoPointLightManip.

🍓 MEMBER DATA DOCUMENTATION 🍓

💫 SoSFVec3f SoPointLight::location 💫

the 3D position of the light source, bestie. that's where your light is at. 🌈

default value is <0, 0, 1> — periodt. 💅
