💖 NAME 💖

So this is SoBlinker(3), straight out of the Coin manual, and she is the cycling switch node. That's the whole vibe: a switch that cycles. Iconic. ✨

🎀 SYNOPSIS 🎀

Bestie, the whole thing lives here:

#include <Inventor/nodes/SoBlinker.h>

She inherits SoSwitch — so everything SoSwitch can do, she can do too. Let's get into it. 💅

Detailed Description

so like, SoBlinker is a cycling switch node. that's the whole personality 🎀

It cycles its children SoBlinker::speed number of times per second. and here's the cute part — if the node has only one child, it just gets cycled on and off. blink. unblink. blink. 💀

You can turn the cycling off with the SoBlinker::on field, and at that point it stops being a blinker and just behaves like a normal SoSwitch node. glow down, honestly. but valid. 🙈

FILE FORMAT/DEFAULTS:

Blinker {
    whichChild -1
    speed 1
    on TRUE
}

Constructor & Destructor Documentation

SoBlinker::SoBlinker (void )

Constructor. hi bestie, welcome to the world 🫶

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

Destructor. and that's the end of the era 😭 (it's protected, so only the family gets to say goodbye)

Member Function Documentation

SoType SoBlinker::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. it's the "what even are you" hotline, and it always answers ✨

SoType SoBlinker::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 like — it's how the code figures out who you actually are at runtime, no catfishing allowed 👑

Reimplemented from SoSwitch.

const SoFieldData ** SoBlinker::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. lowkey an inside-baseball thing, not your problem bestie 💅

const SoFieldData * SoBlinker::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 SoSwitch.

void SoBlinker::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.

Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables. basically it's doing math so the camera knows where you are and doesn't look past you like you're invisible. rude. anyway ✨

Reimplemented from SoSwitch.

void SoBlinker::write (SoWriteAction * action) [virtual]

Action method for SoWriteAction.

Writes out a node object, and any connected nodes, engines etc, if necessary. it's the "put me in the group chat" function 📝

Reimplemented from SoSwitch.

void SoBlinker::notify (SoNotList * l) [protected], [virtual]

Notifies all auditors for this instance when changes are made. change happens → everyone gets the notification → the whole feed updates. periodt 🔔

Reimplemented from SoSwitch.

Member Data Documentation

SoSFFloat SoBlinker::speed

Number of cycles per second. crank it up for chaotic energy, dial it down for a slow, dreamy blink 🌸

SoSFBool SoBlinker::on

Controls whether cycling is on or off. it's literally the on/off switch for the whole bit, bestie 🎀
