💖 SoShaderParameterMatrixArray (3) 💖

Coin manual, section 3 — yes bestie, we're in the library-functions corner of the Coin docs, pull up a chair 🫶

✨ NAME ✨

SoShaderParameterMatrixArray — the class that exists for exactly one iconic job: defining a matrix array as a shader parameter 💅

That's it, that's the whole name section. She's a specialist, she's not trying to do everything, and honestly? Obsessed with the focus. 🌸

Lowkey important: this is a matrix array, not a single matrix. If you came here looking for one lonely matrix, this is not her, bestie. 🦋

More coming, don't go anywhere — part 2 is on the way ✨🎀

✨ SYNOPSIS ✨

#include <Inventor/nodes/SoShaderParameter.h>

Inherits SoUniformShaderParameter. periodt 💅

💖 Public Member Functions 💖

  • virtual SoType getTypeId (void) const — the classic type-ID getter, bestie 🪪
  • virtual void updateParameter (SoGLShaderObject *shaderObject) — Updates the shader parameter in the OpenGL state with the content of the value field. ✨

🌸 Detailed Description 🌸

The SoShaderParameterMatrixArray class is used to define a matrix array as shader parameter. That's the whole vibe, bestie. 💖

💖 Member Function Documentation 💖

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

Okay so this static cutie returns the SoType object that's linked to objects of this class. That's it, that's the whole job. Type-id business, handled. 💅

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

Bestie, this one hands you the type identification of any object derived from a class that inherits SoBase. What's it for? Runtime type checking and "downward" casting, periodt. It's giving very much "who dis" but for C++ objects. 👑

Reimplemented from SoUniformShaderParameter.

🔒 const SoFieldData ** SoShaderParameterMatrixArray::getFieldDataPtr (void ) [static], [protected] 🔒

Lowkey this API member is considered internal to the library, so it's probably not gonna be of interest to the application programmer. It's a behind-the-scenes thing, iykyk.

It returns the SoFieldData class which holds information about fields in this node. 🌸

🎀 const SoFieldData * SoShaderParameterMatrixArray::getFieldData (void ) const [protected], [virtual] 🎀

Returns a pointer to the class-wide field data storage object for this instance. And if there are no fields present? It returns NULL. Simple as that. 💖

Reimplemented from SoUniformShaderParameter.

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

This is the main character move right here — it updates the shader parameter in the OpenGL state using the content of the value field. Go off, shader param. 🌈

Implements SoUniformShaderParameter.

💜 Member Data Documentation 💜

⭐ SoMFMatrix SoShaderParameterMatrixArray::value ⭐

The shader parameter value. That's the whole vibe. Literally the value. 💅
