✨ SoVRMLCoordinateInterpolator(3) ✨

okay so bestie, welcome to the Coin manual, and today's main character is SoVRMLCoordinateInterpolator. no cap, this one's a whole vibe.

🎀 NAME 🎀

SoVRMLCoordinateInterpolator — the class that interpolates 3D coordinates. that's it, that's the whole job, and she does it flawlessly 💅

fr fr, if you came here looking for the class that does the 3D coordinate interpolation thing — you found her. she's literally named exactly what she does. iconic behavior. 👑

heads up bestie, this page is long so it's coming at you in 3 parts — and this is only part 1. more is on the way, don't go anywhere 🦋

✨ SYNOPSIS ✨

okay so before we even get into it, bestie, look at this header name. yes it says Coorinate. that is literally how it's spelled in the file, i am not fixing it, that's on the source code and we respect it 🫶

#include <Inventor/VRMLnodes/SoVRMLCoorinateInterpolator.h>

Inherits SoVRMLInterpolator.

these are the ones this class brings to the party, freshly yours:

✨ Detailed Description ✨

The SoVRMLCoordinateInterpolator class is used to interpolate 3D coordinates. yes bestie, it's literally what it says on the tin 💖

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:

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

This node linearly interpolates among a list of MFVec3f values. the math is mathing ✨ The number of coordinates in the keyValue field shall be an integer multiple of the number of keyframes in the key field. That integer multiple defines how many coordinates will be contained in the value_changed events. 4.6.8, Interpolator nodes (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.8), contains a more detailed discussion of interpolators.

ngl bestie, that "shall be an integer multiple" thing is not a suggestion — it's a requirement, fr fr. 💅

💅 Member Function Documentation 💅

SoType SoVRMLCoordinateInterpolator::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. static method said "I speak for the whole class" 🫶

SoType SoVRMLCoordinateInterpolator::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. type-checking girlies stay winning ⭐

Reimplemented from SoVRMLInterpolator.

const SoFieldData ** SoVRMLCoordinateInterpolator::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 for you, bestie, it's giving internal 🙈

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

const SoFieldData * SoVRMLCoordinateInterpolator::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. and if there are none? NULL. periodt. ✨

Reimplemented from SoVRMLInterpolator.

const SoEngineOutputData * SoVRMLCoordinateInterpolator::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. again with the internal stuff, we're just vibing in the backstage area 🎀

Reimplemented from SoVRMLInterpolator.

void SoVRMLCoordinateInterpolator::initClass (void ) [static]

the initClass girlie has entered the chat 👑 (and yes, that's the whole description right there — no notes, no cap.)
