SoVRMLPosi...terpolator(3)

📦 version 3.1.3, in fedora 43, fedora 44

💅 SoVRMLPositionInterpolator 💅

okay bestie, so this page is from the Library Functions Manual, and the man page itself shows up as SoVRMLPosi...terpolator(3) because terminals are haters and love truncating things. The actual class is SoVRMLPositionInterpolator, and she is that girl for interpolating 3D points. periodt. ✨

🌸 NAME 🌸

SoVRMLPositionInterpolator — the SoVRMLPositionInterpolator class is used to interpolate 3D points. no cap, that's literally her whole job and she ate. 🎀

bestie we are SO not done yet — this was only part 1 of 2. stay tuned, the rest is coming. 💖

💖 Detailed Description 💖

okay bestie, so the SoVRMLPositionInterpolator class is literally the one used to interpolate 3D points. no cap. 🦋

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:

PositionInterpolator {
  eventIn      SFFloat set_fraction        # (-,)
  exposedField MFFloat key           []    # (-,)
  exposedField MFVec3f keyValue      []    # (-,)
  eventOut     SFVec3f value_changed
}

The PositionInterpolator node linearly interpolates among a list of 3D vectors. The keyValue field shall contain exactly as many values as in the key field. 4.6.8, Interpolator nodes (http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.6.8), contains a more detailed discussion of interpolators. periodt. ✨

🛠️ Constructor & Destructor Documentation 🛠️

SoVRMLPositionInterpolator::SoVRMLPositionInterpolator (void )

Constructor. That's it, that's the tea — it constructs. 💅

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

Destructor. It's protected and virtual, so it handles cleanup when the object is done. Don't call it manually unless you're the library, bestie. 💀

✨ Member Function Documentation ✨

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

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

Usage example:

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

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished 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.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoVRMLInterpolator.

const SoFieldData * SoVRMLPositionInterpolator::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 SoVRMLInterpolator.

const SoEngineOutputData * SoVRMLPositionInterpolator::getOutputData (void ) const [virtual]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. So like, not your business unless you're deep in the code. 🙈

📦 Member Data Documentation 📦

SoMFVec3f SoVRMLPositionInterpolator::keyValue

The keyValue vector. That's the whole mood. 🎀

SoEngineOutput SoVRMLPositionInterpolator::value_changed

The eventOut which is sent every time the interpolator has calculated a new value. It's giving notifications, periodt. 🔥
