🌈 Detailed Description 🌈

SoTextureCoordinateNormalMap generates texture coordinates by projecting onto a surrounding texture. periodt. 💅

so the way this works: the texture you point at is the enviroment, and it gets mapped around the scenegraph sitting underneath this node — using a sphere 🫧. and it takes the camera position into account while it does that. which means… your object ends up reflecting its enviroment. iconic behavior honestly, it's giving chrome ball in a photoshoot ✨

here's a scenegraph example showing how enviroment mapping can be applied to an object:

 #Inventor V2.1 ascii

Separator {

 Texture2 { filename "ocean.jpg" # the enviroment, in this case ocean }
TextureCoordinateNormalMap {}

 Cube {} # the enviromentally mapped object }
💀 ngl the formatting in that example is a lil chaotic but it's exactly what the page says, so we're keeping it fr fr

🦋 FILE FORMAT/DEFAULTS: 🦋

TextureCoordinateNormalMap {
}
note: there are literally no fields in there. empty braces. the node is that girl and she needs nothing. 💅

💜 Constructor & Destructor Documentation 💜

🎀 SoTextureCoordinateNormalMap::SoTextureCoordinateNormalMap (void ) 🎀

Constructor. ✨ (yes that's the whole thing, she's lowkey mysterious)

🎀 SoTextureCoordinateNormalMap::~SoTextureCoordinateNormalMap () [protected], [virtual] 🎀

Destructor. 🫶

okay bestie that's the end of part 1 — there's more coming, so don't go anywhere 💖

💖 MEMBER FUNCTION DOCUMENTATION 💖

🌸 SoType SoTextureCoordinateNormalMap::getTypeId (void ) const [virtual]

Okay bestie, this one is so important — it hands you back the type identification of any object that inherits from SoBase. What's it for? Run-time type checking and "downward" casting. That's the whole vibe. 🫶

Usage example, and yes we're keeping it exactly as-is because it's iconic:

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

Now listen — for application programmers who wanna extend the library with new nodes, engines, nodekits, draggers or whatever else, this method needs to be overridden in all subclasses. Not optional, not a suggestion, it's the rule. You typically do this as part of setting up the full type system for your extension classes, which is usually accomplished by using the pre-defined macros available through, for instance, Inventor/nodes/SoSubNode.h (that's SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on and so forth. ✨

For more info on writing Coin extensions, go check the class documentation of the toplevel superclasses for the various class groups. That's where the lore lives. 📚

Reimplemented from SoTextureCoordinateFunction.

🦋 const SoFieldData * SoTextureCoordinateNormalMap::getFieldData (void ) const [protected], [virtual]

This one 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 tea. 🍵

Reimplemented from SoTextureCoordinateFunction.

⭐ void SoTextureCoordinateNormalMap::doAction (SoAction * action) [virtual]

This function performs the typical operation of a node for any action. Like, any action at all, it's got you. 💅

Reimplemented from SoNode.

🔥 void SoTextureCoordinateNormalMap::GLRender (SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction, bestie!

This gets called during rendering traversals. So any node that influences the rendering state in any way, or who wants to throw geometry primitives at OpenGL, overrides this method. Main character energy for real. 👑

Reimplemented from SoNode.

🎀 void SoTextureCoordinateNormalMap::pick (SoPickAction * action) [virtual]

Action method for SoPickAction.

Does common processing for SoPickAction action instances. Lowkey does the shared work so you don't have to. 🙈

Reimplemented from SoNode.

🌈 void SoTextureCoordinateNormalMap::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. Extracting info, slay. 🕵️♀️

Reimplemented from SoNode.

periodt. now go write some texture coordinates. ✨
