🔥 Detailed Description 🔥

The SoTransformation class is the abstract base class for transformation nodes. periodt.

To position and orient geometry within the 3D world space, various node types for transformations are used. These nodes all inherit the SoTransformation base class. so like, they're all siblings in the transformation family 💅.

Note that transformations will be accumulated through the scene graph, unless used under SoSeparator nodes, where the transformation matrix stack will be pushed and popped. Here is a short example demonstrating this principle:
#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:

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

okay bestie, this one is the type-identity detector. It returns the type identification of an object derived from a class inheriting SoBase. This is what you use for run-time type checking and “downward” casting. very demure, very mindful ✨

Usage example:

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

For application programmers who want to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. That’s usually done as part of setting up the full type system for extension classes, and the usual way is 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. periodt 💅
