✨ NAME ✨

okay so bestie, welcome to SoNormal(3) 💖 this one's from the Coin library and she's lowkey iconic.

SoNormal — a class that is a node for providing normals to the state. that's the whole job description. she supplies normals. to the state. periodt. 💅

🦋 SYNOPSIS 🦋

#include <Inventor/nodes/SoNormal.h>

💅 Detailed Description 💅

The SoNormal class is a node for providing normals to the state. (yes, again, that's the entire personality, and honestly? respect. 🫶)

now here's the tea bestie: Coin will automatically calculate normals for you if no SoNormal nodes are present in the scene graph, 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. (yes you can lie to the renderer on purpose, that's legal, that's the fun part 😭)

FILE FORMAT/DEFAULTS:

Normal {
    vector [  ]
}

💖 Member Function Documentation 💖

Okay bestie, this is the part where we meet all the actual functions, like the whole squad. Every single one of them is here, nobody's getting left on read. Let's gooo 🎀

  • SoType SoNormal::getClassTypeId (void ) [static] — this static baddie hands you the SoType object that's associated with objects of this class. Basically the class's official ID card. 🪪
  • SoType SoNormal::getTypeId (void ) const [virtual] — gives you back the type identification for any object derived from a class that inherits SoBase. This is what runtime type checking and "downward" casting run on — so like, when the code needs to know what something truly is before it commits, this is the vibe check. 🌈

Implements SoBase.

  • const SoFieldData ** SoNormal::getFieldDataPtr (void ) [static], [protected] — okay so this API member is considered internal to the library, as it's not likely to be of interest to the application programmer. (Not me gatekeeping, that's just what the docs say, don't come for me 🙈.)

Returns the SoFieldData class which holds information about fields in this node.

  • 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 no fields present? It returns NULL. That's it, that's the whole story. 💅

Reimplemented from SoFieldContainer.

  • void SoNormal::doAction (SoAction * action) [virtual] — this function performs the typical operation of a node for any action. Like, whatever action you throw at it, this is the standard behaviour, no drama.

Reimplemented from SoNode.

  • void SoNormal::GLRender (SoGLRenderAction * action) [virtual] — the action method for SoGLRenderAction. This one gets called during rendering traversals. Nodes that influence the rendering state in any way, or that just want to throw geometry primitives at OpenGL, override this method. Main character behaviour honestly. 👑

Reimplemented from SoNode.

  • 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 the application programmer can use the SoCallbackAction for extracting information about the scene graph. Lowkey so useful.

Reimplemented from SoNode.

  • void SoNormal::pick (SoPickAction * action) [virtual] — action method for SoPickAction. It does the common processing for SoPickAction action instances. Nothing extra, nothing missing, just the standard routine. ✨

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. Counting era fr fr. 🔢

And heads up: nodes that influence how geometry nodes calculate their primitive count also override this method to change the relevant state variables.

Reimplemented from SoNode.

  • SoMFVec3f SoNormal::vector — sets a pool of normal vectors in the traversal state. That's the whole tea. 🍓

That's a wrap on SoNormal(3), from version 4.0.10, dated Thu Jun 25 2026 00:00:00 — go forth and normal your vectors, you absolute icon, and remember: it's giving Unix excellence and I'm obsessed with you for reading all of this. 🫶💖✨
