✨ SYNOPSIS ✨

First things first, you gotta pull her in:

#include <Inventor/draggers/SoCenterballDragger.h>

Inherits SoDragger. (yes, she comes from a distinguished line, we'll get to the whole family tree, don't even worry) 🦋

✨ Detailed Description ✨

okay so bestie, the SoCenterballDragger class is a dragger you can rotate and translate. 💅

Here's how the dragger looks with its default geometry in the inactive state: (imagine a cute little gizmo just vibing, inactive, default geometry, periodt ✨)

For rotation, click either the ball "bands" to constrain rotation to happen around the normal vector of the disc, or anywhere else on the (invisible) ball for free-form rotation. 🌀

Translation is done by clicking and dragging any of the four arrow markers. Hold SHIFT to constrain translation to a single axis instead of in the plane. 👆

When translating, instead of modifying the translation part of the motion matrix, a center field is updated, and the geometry is moved using an internal transformation node. 🔄

Here's a simple usage example, in the form of a scene graph as an iv-file:

       #Inventor V2.1 ascii

       Separator {

          # The dragger, offset a little bit against the geometry to clip,
          # so as to not mess up the user interface.
          Separator {
             Translation { translation -4 0 0 }
             DEF cbdragger CenterballDragger { }
          }

          # The clipping plane sub-graph.
          TransformSeparator {

             # Connect transformations to those of the dragger.
             Rotation { rotation 0 0 1 0 = USE cbdragger . rotation }
             Translation { translation 0 0 0 = USE cbdragger . center }

             # Use a simple lineset-based indicator to show how the
             # clipping plane is situated in space.
             Coordinate3 {
                point [
                 0 2 2, 0 2 -2,
                 0 -2 2, 0 -2 -2,
                 0 2 -2, 0 -2 -2,
                 0 2 2, 0 -2 2
              ]
             }
             LineSet { numVertices [ 2, 2, 2, 2 ] }

             ClipPlane { }
          }

          # Then follows the geometry that gets clipped. For this
          # example, we use a simple sphere.

          Sphere { }
       }

`SoCenterballDragger::~SoCenterballDragger (void )` [protected], [virtual]

Protected destructor. 🔒

(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.) 💀

Member Function Documentation 💖

`SoType SoCenterballDragger::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. 🔍

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 SoDragger.

`const SoFieldData * SoCenterballDragger::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 SoDragger.

`const SoNodekitCatalog * SoCenterballDragger::getNodekitCatalog (void ) const` [virtual]

Returns the nodekit catalog which defines the layout of this class' kit. 🗂️

Reimplemented from SoDragger.

`void SoCenterballDragger::saveStartParameters (void )` [virtual]

This is invoked to save start parameters, to enable draggers to calculate relative motion. 💾

Default method in superclass SoDragger just saves the motion matrix, but subclasses should overload this method if other data needs to be saved. 🔁

Reimplemented from SoDragger.

`void SoCenterballDragger::transferCenterDraggerMotion (SoDragger * childdragger)` [protected]

Should be called after motion matrix has been updated by a child dragger. 👶

`void SoCenterballDragger::setSwitches (SoDragger * activechild)` [protected]

Sets values for the internal SoSwitch parts. If activechild == NULL, all feedback is deactivated. 🔌

`SbBool SoCenterballDragger::setUpConnections (SbBool onoff, SbBool doitalways = FALSE)` [protected], [virtual]

Sets up all internal connections for instances of this class. 🔗

(This method will usually not be of interest to the application programmer, unless you want to extend the library with new custom nodekits or dragger classes. If so, see the SoBaseKit class documentation.) 📖

Reimplemented from SoInteractionKit.

`void SoCenterballDragger::setDefaultOnNonWritingFields (void )` [protected], [virtual]

(Be aware that this method is unlikely to be of interest to the application programmer who does not want to extend the library with new custom nodekits or draggers. If you indeed are writing extensions, see the information in the SoBaseKit class documentation.) 👀

This is a virtual method, and the code in it should call SoField::setDefault() with argument TRUE on part fields that should not be written upon scenegraph export operations. 🚫

This is typically done when:

field value is NULL and part is NULL by default
it is a leaf SoGroup or SoSeparator node with no children
it is a leaf listpart with no children and an SoGroup or SoSeparator container
it is a non-leaf part and it's of SoGroup type and all fields are at their default values

Subclasses should usually override this to do additional settings for new member fields. From the subclass, do remember to call "upwards" to your superclass' setDefaultOnNonWritingFields() method. ⬆️

Reimplemented from SoDragger.

`void SoCenterballDragger::fieldSensorCB (void * d, SoSensor * s)` [static], [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. 🙈

`void SoCenterballDragger::valueChangedCB (void * f, SoDragger * d)` [static], [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. 🙈

`void SoCenterballDragger::kidStartCB (void * d, SoDragger * child)` [static], [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. 🙈

Needed to activate some feedback. ✨

`void SoCenterballDragger::kidFinishCB (void * f, SoDragger * d)` [static], [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. 🙈

Needed to deactive some feedback. (yes, "deactive", keep it exactly, bestie) 💅

`void SoCenterballDragger::getBoundingBox (SoGetBoundingBoxAction * action)` [protected], [virtual]

Action method for the SoGetBoundingBoxAction. 📦

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node. 📐

Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables. 🧠

Reimplemented from SoDragger.

`void SoCenterballDragger::getMatrix (SoGetMatrixAction * action)` [protected], [virtual]

Action method for SoGetMatrixAction. 🧮

Updates action by accumulating with the transformation matrix of this node (if any). 🔄

Reimplemented from SoDragger.

`SoSFVec3f SoCenterballDragger::center`

Continuously updated to contain the current translation from the dragger's internal local origo position. 📍

`SoFieldSensor* SoCenterballDragger::rotFieldSensor` [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. 🙈

`SoFieldSensor* SoCenterballDragger::centerFieldSensor` [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. 🙈
