💖 SoTransformation(3) 💖

okay bestie, pull up a chair, we're doing SoTransformation(3) from the Coin manual 📖✨ and honestly? she's the blueprint. the abstract base class blueprint. no cap 💅

✨ NAME ✨

SoTransformation — The SoTransformation class is the abstract base class for transformation nodes. that's the whole vibe: she's abstract, she's base, and every transformation node in the family inherits from her 👑

🌸 SYNOPSIS 🌸

#include <Inventor/nodes/SoTransformation.h>

Inherits SoNode.

Inherited by SoAntiSquish, SoGeoLocation, SoMatrixTransform, SoResetTransform, SoRotation, SoRotationXYZ, SoScale, SoSurroundScale, SoTransform, SoTranslation, and SoUnits. it's giving dynasty 🧚

🌸 DETAILED DESCRIPTION 🌸

okay bestie, listen up 💖 the SoTransformation class is the abstract base class for transformation nodes. that's the whole vibe. periodt.

so when you wanna position and orient geometry inside the 3D world space, you use the various node types made for transformations — and every single one of them inherits from this SoTransformation base class. proud parent energy fr fr 🫶

⚠️ big important note: transformations get accumulated through the scene graph — unless they're used under SoSeparator nodes, because that's where the transformation matrix stack gets pushed and popped. no cap, this one matters.

here's a short example demonstrating this principle, iykyk:

#Inventor V2.1 ascii

Separator {
   BaseColor { rgb 1 0 0 }
   Cone { }

   Translation { translation 3 0 0 }

   Separator {
      Rotation { rotation 1 0 0  1.57 }
      BaseColor { rgb 0 1 0 }
      Cone { }
   } # SoSeparator restores transformation matrix here

   Translation { translation 3 0 0 }

   Rotation { rotation 1 0 0  1.57 }
   BaseColor { rgb 0 0 1 }
   Cone { }

   Translation { translation 3 0 0 }

   # Last SoRotation was not within SoSeparator, so this next
   # SoRotation will accumulate with the previous.
   Rotation { rotation 1 0 0  1.57 }
   BaseColor { rgb 1 1 0 }
   Cone { }
}

which results in the following scene 👇 (yes, look at it, it's lowkey iconic 🌈)

🎀 CONSTRUCTOR & DESTRUCTOR DOCUMENTATION 🎀

SoTransformation::SoTransformation (void ) [protected]

Constructor. 💅 that's the whole entry. it's [protected], so it's internal-vibes only.

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

Destructor. the goodbye moment 😭 also [protected], also [virtual].

✨ MEMBER FUNCTION DOCUMENTATION ✨

SoType SoTransformation::getClassTypeId (void ) [static]

this static method returns the SoType object associated with objects of this class. 🎀 cute, simple, does exactly what it says.

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

returns the type identification of an object derived from a class inheriting SoBase. this is what's used for runtime type checking and "downward" casting 👑

implements SoBase.

reimplemented in SoAntiSquish, SoCenterballManip, SoGeoLocation, SoHandleBoxManip, SoJackManip, SoMatrixTransform, SoPendulum, SoResetTransform, SoRotation, SoRotationXYZ, SoRotor, SoScale, SoShuttle, SoSurroundScale, SoTabBoxManip, SoTrackballManip, SoTransform, SoTransformBoxManip, SoTransformerManip, SoTransformManip, SoTranslation, and SoUnits. ✨ (that's a lot of children, main character family tree fr)

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

okay so this API member is considered internal to the library, since it's not likely to be of interest to the application programmer 🙈 so don't stress about it bestie.

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

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

returns a pointer to the class-wide field data storage object for this instance. if no fields are present, it returns NULL. 💀 yes, literally NULL.

reimplemented from SoFieldContainer.

reimplemented in SoAntiSquish, SoCenterballManip, SoGeoLocation, SoHandleBoxManip, SoJackManip, SoMatrixTransform, SoPendulum, SoResetTransform, SoRotation, SoRotationXYZ, SoRotor, SoScale, SoShuttle, SoSurroundScale, SoTabBoxManip, SoTrackballManip, SoTransform, SoTransformBoxManip, SoTransformerManip, SoTransformManip, SoTranslation, and SoUnits. 🦋
