💜 Detailed Description 💜

okay so <pink>SoTextureCoordinate3</pink> is the class that holds a set of coordinates for the mapping of 2D textures. that's the headline, that's the thesis, that's the whole point of her existence. 🌸

When traversal runs into nodes of this type, the coordinates she's holding get <purple>put on the state stack</purple>. Then some shape nodes can grab those coordinates and use them for <mint>explicit, detailed control</mint> over how 3D textures get mapped. so like, you're the one deciding. main character energy, no notes. 👑

and bestie, real talk: if 3D textures are used with <cyan>no</cyan> SoTextureCoordinate3 nodes anywhere in the scenegraph leading up to a shape node, the shape types have default fallbacks. so you only actually need SoTextureCoordinate3 nodes if the default mapping is giving you the ick and you're not satisfied with it. 🙈

Also super important, do not skip this: an SoTextureCoordinate3 node will <red>replace</red> the coordinates already present in the state (if there were any). not merge, not vibe alongside — replace. fr fr. 💀

⚠️ heads up: this class is an <yellow>extension for Coin</yellow>, and it is <yellow>not available</yellow> in the original SGI Open Inventor v2.1 API. so if you're porting to that, she's not coming with you. 😭

🛠️ Constructor & Destructor Documentation 🛠️

SoTextureCoordinate3::SoTextureCoordinate3 (void )

Constructor. that's the birth of the girl herself, no extra lore given, just vibes. ✨

SoTextureCoordinate3::~SoTextureCoordinate3 () [protected], [virtual]

Destructor. it's <purple>protected</purple> and <purple>virtual</purple>, so you can't just call her up and end her yourself — she handles her own exit. 💅

✨ Member Function Documentation ✨

  • SoType SoTextureCoordinate3::getTypeId(void) const [virtual]

Okay bestie, this one is the vibe check for objects 💅 It hands you back the type identification of any object derived from a class that inherits SoBase. What's it for? Run-time type checking, and "downward" casting. iykyk.

Usage example, and yes it's literally this:

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 whatever else — listen up 🫶 this method needs to be overridden in all subclasses. That's typically done as part of setting up the full type system for extension classes, and it's usually accomplished with 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. Slay.

Implements SoBase. 🎀

  • const SoFieldData * SoTextureCoordinate3::getFieldData(void) const [protected], [virtual]

This one's giving "where is everything stored" energy — it 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 whole thing. 🙈

Reimplemented from SoFieldContainer.

  • void SoTextureCoordinate3::doAction(SoAction * action) [virtual]

The main character of node behaviour right here 👑 this function performs the typical operation of a node for any action.

Reimplemented from SoNode.

  • void SoTextureCoordinate3::GLRender(SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction. This gets called during rendering traversals, no cap. Any node that influences the rendering state in literally any way, or who wants to throw geometry primitives at OpenGL, overrides this method. 🔥

Reimplemented from SoNode.

  • void SoTextureCoordinate3::callback(SoCallbackAction * action) [virtual]

Action method for SoCallbackAction. It 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 genius. 💜

Reimplemented from SoNode.

  • void SoTextureCoordinate3::pick(SoPickAction * action) [virtual]

Action method for SoPickAction. Does common processing for SoPickAction action instances. Simple, iconic, done. ✨

Reimplemented from SoNode.

💖 Member Data Documentation 💖

  • SoMFVec3f SoTextureCoordinate3::point

The set of 3D texture coordinates, bestie 🌸 The default value of this field is an empty set.

Now here's the tea: texture coordinates are usually specified in normalized coordinates, aka the range [0, 1]. And coordinates outside that [0, 1] range? They can be used to repeat the texture across a surface. Not me finding that so useful 😭
