SoPendulum(3)

📦 version 3.1.3, in fedora 43, fedora 44

🎀 SoPendulum 🎀

okay bestie, welcome to the SoPendulum(3) manual page — yes it's a whole 3-section library function page and yes it's lowkey iconic. Sit down, grab a strawberry 🍓, we're doing this.

✨ NAME ✨

SoPendulum — the class that makes oscillating rotations. That's it. That's the vibe. It swings back and forth, forever, like your mood at 2am. 💅

🌸 SYNOPSIS 🌸

#include <Inventor/nodes/SoPendulum.h>

Inherits SoRotation. So it's giving "rotation, but with ✨extra steps✨".

💅 Detailed Description 💅

okay so the SoPendulum class is used to create oscillating rotations. It literally swings. Main character energy, no cap. 🕰️

A smooth transition between rotation0 and rotation1 is created using a cosine function. In the beginning of the cycle, rotation0 is used. Halfway through the cycle, the resulting rotation equals rotation1, and at the end of the cycle, we're at rotation0 again. So it's a full round trip bestie, a whole journey, and then it does it all over again. Obsessed. 😭✨

📄 FILE FORMAT/DEFAULTS

Pendulum {
    rotation 0 0 1  0
    rotation0 0 0 1  0
    rotation1 0 0 1  0
    speed 1
    on TRUE
}
not me noticing the double space in 0 0 1 0 — that's intentional, leave it alone bestie, it's canon 💀

🛠️ Constructor & Destructor Documentation 🛠️

🎀 SoPendulum::SoPendulum (void )

Constructor. It's born. ✨

🎀 SoPendulum::~SoPendulum () [protected], [virtual]

Destructor. It's protected, it's virtual, it's saying goodbye in the most lowkey way possible. 🙈

…and that's only part 1, bestie. there's MORE. keep scrolling (or, yk, wait for part 2) 💖🦋

✨ Member Function Documentation ✨

bestie we're in the function zone now 💅 let's get into it.

🦋 SoType SoPendulum::getTypeId (void ) const [virtual] 🦋

okay so like, this method is literally the ID card for any object that inherits from SoBase. it's giving run-time type checking and "downward" casting energy. no cap.

usage example:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

so for all my application programmers who wanna extend the library with new nodes, engines, nodekits, draggers or whatever — you HAVE to override this method in all subclasses. it's not a suggestion, it's a periodt. this is usually part of setting up the full type system for extension classes, and you do it by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on. iykyk.

for more information on writing Coin extensions, check the class documentation of the toplevel superclasses for the various class groups. it's giving main character energy.

🫶 Reimplemented from SoRotation.

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

returns a pointer to the class-wide field data storage object for this instance. if there are no fields present, it returns NULL. that's it, that's the vibe. Reimplemented from SoRotation.

💅 void SoPendulum::write (SoWriteAction * action) [virtual] 💅

action method for SoWriteAction. writes out a node object, and any connected nodes, engines etc, if necessary. lowkey essential. Reimplemented from SoNode.

🎀 Member Data Documentation 🎀

okay now the data members, the real MVPs 💖

🌈 SoSFRotation SoPendulum::rotation0 🌈

the first rotation limit of the interpolation. periodt.

🦋 SoSFRotation SoPendulum::rotation1 🦋

the other rotation limit of the interpolation. no cap.

⭐ SoSFFloat SoPendulum::speed ⭐

speed in cycles per second. defaults to 1. so if you don't set it, it's giving 1 cycle per sec.

💜 SoSFBool SoPendulum::on 💜

toggles animation on or off. defaults to being on. so it's on by default, bestie.
