🎀 Detailed Description 🎀

Okay so. SoCoordinate4 is a node whose entire personality is providing coordinates to shape nodes. That's the vibe, that's the assignment, she ate 💅

Here's the tea: when traversal bumps into nodes of this type, the coordinates she's holding get put onto the state stack, so shape nodes that need coordinate sets can come grab them later. We're talking types like SoFaceSet nodes or SoPointSet nodes 🦋

Now, the fourth element of the coordinate vectors? That one is used for normalization. And here's the cute part: a node of this type where all the normalization values are equal to 1.0 is the equivalent of setting up an SoCoordinate3 node. Same energy, different class ✨

⚠️ Heads up bestie: an SoCoordinate4 node will replace the coordinates already present in the state (if any). Not merge, not stack, replace. She's not sharing the spotlight 😭

FILE FORMAT/DEFAULTS:

Coordinate4 {
    point 0 0 0 1
}

🦋 Constructor & Destructor Documentation 🦋

SoCoordinate4::SoCoordinate4 (void )

Constructor. She's born 🎀

SoCoordinate4::~SoCoordinate4 () [protected], [virtual]

Destructor. She's gone, but iconic forever 💜

✨ Member Function Documentation ✨

Okay bestie, this is where the actual magic happens — all the methods that make SoCoordinate4 do its lil thing. Buckle up. 🎀

SoType SoCoordinate4::getClassTypeId (void ) [static]

SoType SoCoordinate4::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. Static means you don't even need an instance, she just knows who she is. 💅

SoType SoCoordinate4::getTypeId (void ) const [virtual]

SoType SoCoordinate4::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. So basically the vibe check for your class hierarchy. 👑

Implements SoBase.

const SoFieldData ** SoCoordinate4::getFieldDataPtr (void ) [static], [protected]

const SoFieldData ** SoCoordinate4::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. Not me reading the library's private diary tbh. 🙈

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

const SoFieldData * SoCoordinate4::getFieldData (void ) const [protected], [virtual]

const SoFieldData * SoCoordinate4::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. Zero fields? Cute, empty, minimal, iconic. 🦋

Reimplemented from SoFieldContainer.

void SoCoordinate4::doAction (SoAction * action) [virtual]

void SoCoordinate4::doAction (SoAction * action) [virtual]

This function performs the typical operation of a node for any action. Any action? She's versatile, she contains multitudes. ✨

Reimplemented from SoNode.

void SoCoordinate4::GLRender (SoGLRenderAction * action) [virtual]

void SoCoordinate4::GLRender (SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method. Throwing geometry at OpenGL is literally her cardio. 🔥

Reimplemented from SoNode.

void SoCoordinate4::getBoundingBox (SoGetBoundingBoxAction * action) [virtual]

void SoCoordinate4::getBoundingBox (SoGetBoundingBoxAction * action) [virtual]

Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node. It's giving "I contain this whole area code." 💖

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

Reimplemented from SoNode.

void SoCoordinate4::callback (SoCallbackAction * action) [virtual]

void SoCoordinate4::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. Sneaky lil info extraction? Obsessed. 🍓

Reimplemented from SoNode.

void SoCoordinate4::pick (SoPickAction * action) [virtual]

void SoCoordinate4::pick (SoPickAction * action) [virtual]

Action method for SoPickAction.

Does common processing for SoPickAction action instances. Pick me, choose me, process me. 💅

Reimplemented from SoNode.

void SoCoordinate4::getPrimitiveCount (SoGetPrimitiveCountAction * action) [virtual]

void SoCoordinate4::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. Math but make it fashion. 🎀

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

Reimplemented from SoNode.

✨ Member Data Documentation ✨

SoMFVec4f SoCoordinate4::point

SoMFVec4f SoCoordinate4::point

Coordinate set of 3D points as 4D vectors (each vector contains a 3D coordinate plus normalization value). Four numbers doing the job of three, plus a lil extra normalization garnish. 🌸
