🔥 Detailed Description 🔥

Ok so real talk: the SoTextureMatrixTransform class is used to define a texture matrix transformation. That's the whole job. 💖

Textures applied to shapes in the scene can be transformed by "prefixing" in the state with instances of this node type. So like, you drop one of these bad boys into the scene graph and it quietly rearranges how the texture sits on everything downstream. Main character energy, honestly. 👑

Heads up bestie: be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API. So if you're kicking it old-school, this one's not gonna be there. 😭

FILE FORMAT/DEFAULTS:

TextureMatrixTransform {
    matrix
      1 0 0 0
      0 1 0 0
      0 0 1 0
      0 0 0 1
}

That's the identity matrix, default-coded, doing nothing at all until you tell it to. So iconic of it. ✨

🎀 Constructor & Destructor Documentation 🎀

💖 SoTextureMatrixTransform::SoTextureMatrixTransform (void ) 💖

Constructor. Builds the thing. That's the vibe. 🫶

💀 SoTextureMatrixTransform::~SoTextureMatrixTransform () [protected], [virtual] 💀

Destructor. Protected, virtual, and it's the one that cleans up after the party. 🧹✨

💖 Member Function Documentation 💖

✨ SoType SoTextureMatrixTransform::getTypeId (void ) const [virtual] ✨

Okay bestie, this one hands you the type identification of any object that descends from a class inheriting SoBase. What's it for? Run-time type checking and "downward" casting, periodt. That's literally the whole job.

Usage example, and yes we're keeping it verbatim because it's iconic:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

Now for the application programmers out there who wanna extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. No skipping, no shortcuts. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on. 🫶

Want more tea on writing Coin extensions? Go read the class documentation of the toplevel superclasses for the various class groups. It's giving homework but make it lore.

Implements SoBase.

✨ const SoFieldData * SoTextureMatrixTransform::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. That's it, that's the vibe. 🙈

Reimplemented from SoFieldContainer.

---

✨ void SoTextureMatrixTransform::doAction (SoAction * action) [virtual] ✨

This function performs the typical operation of a node for any action. Any action. It's the main character of action-handling, fr fr.

Reimplemented from SoNode.

---

✨ void SoTextureMatrixTransform::callback (SoCallbackAction * action) [virtual] ✨

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph. Lowkey a little spy for your scene graph. 🕵️‍♀️

Reimplemented from SoNode.

---

✨ void SoTextureMatrixTransform::GLRender (SoGLRenderAction * action) [virtual] ✨

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way, or who wanna throw geometry primitives at OpenGL, override this method. Go off, OpenGL. 🔥

Reimplemented from SoNode.

---

✨ void SoTextureMatrixTransform::getMatrix (SoGetMatrixAction * action) [virtual] ✨

Action method for SoGetMatrixAction.

Updates action by accumulating with the transformation matrix of this node (if any). "If any" — the audacity, but okay. 💅

Reimplemented from SoNode.

---

✨ void SoTextureMatrixTransform::pick (SoPickAction * action) [virtual] ✨

Action method for SoPickAction.

Does common processing for SoPickAction action instances. Just the usual, nothing dramatic. 🌸

Reimplemented from SoNode.
