πŸ“– Detailed Description πŸ“–

Okay bestie, listen. The SoNormal class is a node for providing normals to the state. That's the vibe. ✨

Coin will automatically calculate normals for you if no SoNormal nodes are present in the scene graph β€” yes, she does it herself, she's that girl. But explicitly setting normals is useful for at least two purposes:

  1. a potential increase in performance
  2. you can calculate and use "incorrect" normals to do various special effects
Not me telling you that "wrong" normals are a whole aesthetic. They are. That's the point. πŸ”₯

FILE FORMAT/DEFAULTS:

Normal {
    vector [  ]
}

πŸŽ€ Constructor & Destructor Documentation πŸŽ€

✨ SoNormal::SoNormal (void ) ✨

Constructor. She's born. πŸ’–

πŸ’€ SoNormal::~SoNormal () [protected], [virtual] πŸ’€

Destructor. She's gone. πŸ₯²


✨ Member Function Documentation ✨

Okay bestie, this is the part where we meet the actual methods β€” the little moves SoNormal pulls when the scene graph comes knocking. Strap in. πŸŽ€


πŸ¦‹ SoType SoNormal::getTypeId (void) const [virtual]

Hands you back the type identification of any object derived from a class that inherits SoBase. It's the whole reason run-time type checking and "downward" casting even work, no cap.

Usage example, copy it, love it, use it:

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

Now listen β€” if you're an application programmer and you wanna extend the library with new nodes, engines, nodekits, draggers or whatever else you dream up: you have to override this method in all subclasses. Periodt. This is usually done as part of setting up the full type system for your extension classes, and that's typically accomplished with the pre-defined macros available through, for instance:

  • Inventor/nodes/SoSubNode.h β€” which gives you SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes
  • Inventor/engines/SoSubEngine.h β€” for engine classes
  • and so on, you get the vibe πŸ’…

Want the full tea on writing Coin extensions? Go read the class documentation of the toplevel superclasses for the various class groups. They explain it way better than I could in a group chat.

Implements SoBase.


🧚 const SoFieldData * SoNormal::getFieldData (void) const [protected], [virtual]

Returns a pointer to the class-wide field data storage object for this instance. And if there are literally no fields present? It returns NULL. That's it, that's the whole function. 🫢

Reimplemented from SoFieldContainer.


πŸ’– void SoNormal::doAction (SoAction * action) [virtual]

This one performs the typical operation of a node for any action. The all-rounder. The main character of action methods. πŸ‘‘

Reimplemented from SoNode.


🌈 void SoNormal::GLRender (SoGLRenderAction * action) [virtual]

The action method for SoGLRenderAction, bestie β€” it gets called during rendering traversals.

Any node that influences the rendering state in any way, or who just wants to throw geometry primitives at OpenGL, overrides this method. That's the assignment. ✨

Reimplemented from SoNode.


πŸ“ void SoNormal::callback (SoCallbackAction * action) [virtual]

Action method for SoCallbackAction.

It simply updates the state according to how the node behaves for the render action, so that you, the application programmer, can use SoCallbackAction to extract information about the scene graph. Very demure, very useful. πŸ’…

Reimplemented from SoNode.


🌸 void SoNormal::pick (SoPickAction * action) [virtual]

Action method for SoPickAction.

It does the common processing for SoPickAction action instances. Lowkey essential, highkey underrated. πŸŽ€

Reimplemented from SoNode.


⭐ void SoNormal::getPrimitiveCount (SoGetPrimitiveCountAction * action) [virtual]

Action method for the SoGetPrimitiveCountAction.

It calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action. Math girlies rise. πŸ”₯

Heads up: nodes that influence how geometry nodes calculate their primitive count also override this method, so they can change the relevant state variables.

Reimplemented from SoNode.


πŸŽ€ Member Data Documentation πŸŽ€

πŸ’œ SoMFVec3f SoNormal::vector

Sets a pool of normal vectors in the traversal state. That's the whole vibe β€” it's the data behind all the fancy footwork above. πŸ‘‘
