🦋 SoShaderParameterArray4f(3) — Coin manual, section 3

okay bestie, welcome to the Coin docs 💖 this one's a short lil intro page so let's not drag it out — the real tea comes in parts 2 and 3, so stay with me.

✨ NAME ✨

SoShaderParameterArray4f — the class that lets you define a four-dimensional floating point array as a shader parameter. 🎀

That's it. That's the whole vibe. She's a shader parameter, she's an array, she's 4f (four floats per element, no cap), and she's here to get your data from your scene graph into your shader. 🫶

no spoilers, but the synopsis, the full description and the actual API are all coming in the next parts — this page is just the glow-up introduction, so don't @ me yet. 💅

to be continued… 🌸

✨ SYNOPSIS ✨

#include <Inventor/nodes/SoShaderParameter.h>

Inherits SoUniformShaderParameter.

💖 Public Member Functions 💖

  • virtual SoType getTypeId (void) const
  • virtual void updateParameter (SoGLShaderObject *shaderObject) — bestie, this one updates the shader parameter in the OpenGL state with whatever's chillin' in the value field. it's giving "sync me up" energy fr fr.

📖 Detailed Description 📖

The SoShaderParameterArray4f class is used to define a four-dimensional floating point array as shader parameter. that's it, that's the vibe — a whole 4-float array, dressed up as a shader parameter, serving looks to your GLSL 💅✨

💅 Member Function Documentation 💅

✨ SoType SoShaderParameterArray4f::getClassTypeId(void) [static] ✨

okay bestie, this one's a static method and it literally just hands you back the SoType object that's tied to objects of this class. that's it. that's the whole vibe. type ID for the class itself, no instance needed 🎀

🦋 SoType SoShaderParameterArray4f::getTypeId(void) const [virtual] 🦋

this one gives you the type identification for an object that's derived from a class inheriting SoBase. what's it for? runtime type checking, and "downward" casting — iykyk, it's how you peek at what something actually is at runtime instead of just trusting the pointer type 💀

Reimplemented from SoUniformShaderParameter.

🎀 const SoFieldData ** SoShaderParameterArray4f::getFieldDataPtr(void) [static], [protected] 🎀

ngl bestie, this API member is considered internal to the library — it's not likely to be of interest to the application programmer, so if you're just writing an app, this is not your moment 🙈

what does it return though? the SoFieldData class that holds info about the fields in this node. so like, the metadata about the fields, not the fields themselves. very behind-the-scenes, very backstage-pass energy 🎟️

🌸 const SoFieldData * SoShaderParameterArray4f::getFieldData(void) const [protected], [virtual] 🌸

this hands you a pointer to the class-wide field data storage object for this instance. one little caveat though, and it matters: if there are no fields present, it returns NULL. so check that pointer before you go dereferencing, bestie, fr fr 😭

Reimplemented from SoUniformShaderParameter.

🔥 void SoShaderParameterArray4f::updateParameter(SoGLShaderObject * shaderObject) [virtual] 🔥

this is the main character method right here 👑 it updates the shader parameter in the OpenGL state using the content of the value field. so whatever's sitting in value, that's what goes into the GL state. slay.

Implements SoUniformShaderParameter.

⭐ SoMFVec4f SoShaderParameterArray4f::value ⭐

the shader parameter value. that's the whole thing. that's the data. it's a SoMFVec4f, it's the value, and updateParameter() above is what ships it off to the OpenGL state 💖
