💅 Detailed Description 💅

The SoVRMLNormal class is used to bind normals to geometry. (yes bestie, same line as NAME, it really said that twice, and we respect the repetition 💀)

The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:

Normal {
  exposedField MFVec3f vector  []   # (-,)
}

This node defines a set of 3D surface normal vectors to be used in the vector field of some geometry nodes (e.g., SoVRMLIndexedFaceSet and SoVRMLElevationGrid). This node contains one multiple-valued field that contains the normal vectors. Normals shall be of unit length. 👑 (unit length, no cap, that's the rule)

🎀 Constructor & Destructor Documentation 🎀

💜 SoVRMLNormal::SoVRMLNormal (void )

Constructor. makes the thing, iconic behaviour honestly.

💜 SoVRMLNormal::~SoVRMLNormal () [protected], [virtual]

Destructor. it's protected and virtual, so you can't just delete it from the outside, bestie — that's an inside job.

and that's it for part 1... stay tuned, more of this page is coming 🦋✨

✨ Member Function Documentation ✨

okay bestie, this is the whole roster of member functions, and we are not skipping a single one 💅

SoType SoVRMLNormal::getClassTypeId (void ) [static]

This static method is the one that hands you back the SoType object that's linked to objects of this class. It's like the class's official ID card, fr fr 🪪

SoType SoVRMLNormal::getTypeId (void ) const [virtual]

Returns the type identification of an object derived from a class that inherits SoBase. This is the whole reason runtime type checking and "downward" casting even work. It implements SoBase, periodt.

const SoFieldData ** SoVRMLNormal::getFieldDataPtr (void ) [static], [protected]

ngl, this API member is considered internal to the library, because it's not likely to be of interest to the application programmer. It returns the SoFieldData class, which is the thing that holds information about fields in this node. ✨

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

Hands back a pointer to the class-wide field data storage object for this specific instance. If there are no fields present, it returns NULL. This one is reimplemented from SoFieldContainer.

void SoVRMLNormal::initClass (void ) [static]

No description given, but it's here, it's static, and it's iconic. 💅

void SoVRMLNormal::doAction (SoAction * action) [virtual]

This function performs the typical operation of a node for any action. It's reimplemented from SoNode.

void SoVRMLNormal::GLRender (SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction. This gets called during rendering traversals. Any node that influences the rendering state in any way, or that wants to throw geometry primitives at OpenGL, overrides this method. Reimplemented from SoNode.

void SoVRMLNormal::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. Reimplemented from SoNode.

void SoVRMLNormal::pick (SoPickAction * action) [virtual]

Action method for SoPickAction. It does the common processing for SoPickAction action instances. Reimplemented from SoNode.

void SoVRMLNormal::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. Nodes that influence how geometry nodes calculate their primitive count also override this method to change the relevant state variables. Reimplemented from SoNode.
