NAME

SoVRMLInterpolator(3) — bestie, this is the internal abstract class. No cap. 💅

SYNOPSIS

okay so first things first, you gotta include this header:

#include <Inventor/VRMLnodes/SoVRMLInterpolator.h>

And here's the tea: this class inherits from SoNodeEngine. And it's inherited by SoVRMLColorInterpolator, SoVRMLCoordinateInterpolator, SoVRMLNormalInterpolator, SoVRMLOrientationInterpolator, SoVRMLPositionInterpolator, and SoVRMLScalarInterpolator. Slay. ✨

📖 DETAILED DESCRIPTION 📖

okay bestie so SoVRMLInterpolator is an internal abstract class. like, it's not here to be the main character, it's here to do the behind-the-scenes work 💅

What it does: it collects the two fields that every interpolator node has in common, plus the shared code that operates on those fields. It's basically the group chat that all the interpolator nodes are in 🫶

IMPORTANT since this is an abstract "helper" class, it does not represent an actual node from the VRML97 specification — so do not use it as one. fr fr. it's giving scaffolding, not building 🚧

Want the full lore? There's a detailed discussion of interpolators in section 4.6.8 of the VRML97 specification:

http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.8

🛠️ MEMBER FUNCTION DOCUMENTATION 🛠️

✨ SoType SoVRMLInterpolator::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. it's the ID card check bestie 🪪

✨ SoType SoVRMLInterpolator::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. lowkey the vibe check for your object hierarchy 👑

Implements SoBase.

Reimplemented in SoVRMLColorInterpolator, SoVRMLCoordinateInterpolator, SoVRMLNormalInterpolator, SoVRMLOrientationInterpolator, SoVRMLPositionInterpolator, and SoVRMLScalarInterpolator. the whole squad showed up 💖

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

heads up this API member is considered internal to the library, as it is not likely to be of interest to the application programmer. iykyk 🤫

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

✨ const SoFieldData * SoVRMLInterpolator::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. not me returning NULL when there's nothing to say 😭

Reimplemented from SoFieldContainer.

Reimplemented in SoVRMLColorInterpolator, SoVRMLCoordinateInterpolator, SoVRMLNormalInterpolator, SoVRMLOrientationInterpolator, SoVRMLPositionInterpolator, and SoVRMLScalarInterpolator. slay 💅

✨ const SoEngineOutputData * SoVRMLInterpolator::getOutputData (void ) const [virtual]

heads up again this API member is considered internal to the library, as it is not likely to be of interest to the application programmer. it's giving ✨forbidden knowledge✨ but it's actually just plumbing 🔧

Implements SoNodeEngine.

Reimplemented in SoVRMLColorInterpolator, SoVRMLCoordinateInterpolator, SoVRMLNormalInterpolator, SoVRMLOrientationInterpolator, SoVRMLPositionInterpolator, and SoVRMLScalarInterpolator. periodt 🌸

✨ void SoVRMLInterpolator::initClass (void ) [static]

(this one's just chillin' with no description, iconic behavior honestly 🎀)

✨ int SoVRMLInterpolator::getKeyValueIndex (float & interp, int numvalues) [protected]

and another one this API member is considered internal to the library, as it is not likely to be of interest to the application programmer. move along bestie, nothing for us here 🙈

🔑 MEMBER DATA DOCUMENTATION 🔑

💖 SoMFFloat SoVRMLInterpolator::key

This field contains a set of floating point values which the interpolation will run over. The key values should be monotonically non-decreasing. no going backwards, we're moving forward in this house 📈

The field is inherited from its declaration in the abstract SoVRMLInterpolator class into a range of different VRML interpolator nodes. it's giving family heirloom 🧬

See the class documentation of the non-abstract VRML interpolator node you want to use for information on what the key values represent in that specific context. every node has its own meaning for these, so check the one you actually want 🦋

💖 SoSFFloat SoVRMLInterpolator::set_fraction

The set_fraction field gets an input signal that triggers a calculation of the next value_changed eventOut value. it's the "go" button basically 🔥

The field is inherited from its declaration in the abstract SoVRMLInterpolator class into a range of different VRML interpolator nodes. same heirloom situation, passed down the whole tree 💜

okay that's the whole page bestie, you ate that 💅 this was Coin version 4.0.10, dated Thu Jun 25 2026 00:00:00, filed under SoVRMLInterpolator(3) — go forth and interpolate, but NOT with the abstract one, i'm serious 😤🫶
