🌸 Detailed Description 🌸

The SoNormalBinding class is a node for specifying normal vector bindings. use nodes of this type to specify how to map normal vectors from SoNormal nodes in the scene graph to shape nodes. periodt. 💅

FILE FORMAT/DEFAULTS:

NormalBinding {
    value PER_VERTEX_INDEXED
}

✨ Member Enumeration Documentation ✨

🎀 enum SoNormalBinding::Binding

Okay bestie, this enum is literally the whole menu of mapping types you can pick from 💅 — it's the list of available types of mappings. The actual tea on what each value means lives in the docs for the SoMaterialBinding node, so go sip there if you want the full explanation of the different values.

⚠️ Heads up: SoNormalBinding::DEFAULT and SoNormalBinding::NONE have been obsoleted, and both of them are mapped to SoNormalBinding::PER_VERTEX_INDEXED. Periodt, they're relics.

Enumerator

  • PER_PART — grab a fresh normal from the pool of normal values for every part of the shape, where what counts as a "part" depends on the shape type. 🫶

Normals get fetched starting at index 0 and onward, bumping the index into the normal pool up by 1 for each new part, in the order defined by that particular shape type.

Important portability note, fr fr: back in the day with the SGI Inventor library, it was allowed to supply too few colors compared to the number of parts of the subsequent shapes in the scene graph. Coloring would then cycle through whatever colors were available. 🙈

Since SGI Open Inventor v2.1, that was disallowed — you must supply enough normals for all parts, or the behavior will be unspecified (and like, probably gonna crash, in fact 💀). Also ngl, the Inventor Mentor book has a description of that old, invalid behavior in Chapter 5, section "Binding Nodes" (middle of page 128 in the 10th printing). So don't copy that homework, it's outdated.

  • PER_PART_INDEXED — grab a fresh normal from the pool of normal values for every part of the shape, where what counts as a "part" depends on the shape type. ✨

Normals get fetched by the index value settings of the shape.

  • PER_FACE — grab a fresh normal from the pool of normal values for each polygon face of the shape. 🌸

Normals get fetched starting at index 0 and onward, bumping the index into the normal pool up by 1 for each new face of the shape node.

Note: individual faces after tessellation of complex shapes (like SoCylinder nodes) are not considered separate entities, so this binding gets treated the same way as SoNormalBinding::PER_PART for those. iykyk.

  • PER_FACE_INDEXED — grab a fresh normal from the pool of normal values for each polygon face of the shape. 💖

Normals get fetched by the index value settings of the shape.

Note: individual faces after tessellation of complex shapes (like SoCylinder nodes) are not considered separate entities, so this binding gets treated the same way as SoNormalBinding::PER_PART_INDEXED for those.

  • PER_VERTEX — grab a fresh normal from the pool of normal values for each polygon, line or point vertex of the shape. ⭐

Normals get fetched starting at index 0 and onward, bumping the index into the normal pool up by 1 for each new vertex of the shape node.

  • PER_VERTEX_INDEXED — grab a fresh normal from the pool of normal values for each polygon, line or point vertex of the shape. 🦋

Normals get fetched by the index value settings of the shape.

  • DEFAULT — Obsolete. Don't use this value. 🚫
  • NONE — Obsolete. Don't use this value. 🚫

🌈 Constructor & Destructor Documentation 🌈

SoNormalBinding::SoNormalBinding (void )

Constructor. The birth of the vibe. 🎀

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

Destructor. She's leaving the group chat. 😭

💅 Member Function Documentation 💅

SoType SoNormalBinding::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. ✨

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

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting. 👑

Implements SoBase.

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

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. 🙈

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

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

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. 🫶

Reimplemented from SoFieldContainer.

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

This function performs the typical operation of a node for any action. The main character doing main character things. 💅

Reimplemented from SoNode.

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

Action method for the SoGLRenderAction. 🔥

This is called during rendering traversals. Nodes influencing the rendering state in any way, or that want to throw geometry primitives at OpenGL, override this method.

Reimplemented from SoNode.

void SoNormalBinding::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.

Reimplemented from SoNode.

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

Action method for SoPickAction. 🎯

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

void SoNormalBinding::getPrimitiveCount (SoGetPrimitiveCountAction * action) [virtual]

Action method for the SoGetPrimitiveCountAction. 🔢

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables.

Reimplemented from SoNode.

SbBool SoNormalBinding::readInstance (SoInput * in, unsigned short flags) [protected], [virtual]

This method is mainly intended for internal use during file import operations. 🤫

It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistent representation of an instance of this class type.

TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went OK or not. The import process should be robust and handle corrupted input streams by returning FALSE.

flags is used internally during binary import when reading user extension nodes, group nodes or engines.

Reimplemented from SoNode.
