💖 Detailed Description 💖

The SoTransformManip class is used to manipulate transformations. ✨

A manipulator is used by replacing the node you want to edit in the graph with the manipulator. Draggers are used to manipulate the node. When manipulation is finished, the node is put back into the graph, replacing the manipulator. it's giving "swap in, glow up, swap out" 💅

The SoTransformManip class is an abstract class which should not be used directly -- use one of its subclasses. like, do NOT try to instantiate this one, bestie, it will simply not be the vibe. go pick a subclass 🫶

The destructor. bye babe 👋

✨ Member Function Documentation ✨

SoType SoTransformManip::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class.

SoType SoTransformManip::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. fr fr, this is how you figure out what you're actually looking at 👑

Reimplemented from SoTransform.

Reimplemented in SoCenterballManip, SoHandleBoxManip, SoJackManip, SoTabBoxManip, SoTrackballManip, SoTransformBoxManip, and SoTransformerManip.

const SoFieldData ** SoTransformManip::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.

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

const SoFieldData * SoTransformManip::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 SoTransform.

Reimplemented in SoCenterballManip, SoHandleBoxManip, SoJackManip, SoTabBoxManip, SoTrackballManip, SoTransformBoxManip, and SoTransformerManip.

SoDragger * SoTransformManip::getDragger (void )

Returns the dragger used by this manipulator. that's the little guy doing the actual dragging 🫳✨

SbBool SoTransformManip::replaceNode (SoPath * path)

Replaces a node at the tail of path with this manipulator. The node must be an instance of a node class derived from SoTransform.

The manipulator will when inserted automatically copy the field data from the node, to make it initially affect the state in the same way as the node.

Returns TRUE if successful, and FALSE if the given node could not be replaced with the manipulator. The operation will for instance fail if the tail node of the given path is not of SoTransform type, or for any other condition where it is not possible to replace the node with this manipulator.

so like, check your return value, bestie. FALSE means it did not slay 😭

SbBool SoTransformManip::replaceManip (SoPath * path, SoTransform * newone) const

Replaces this manipulator from the position specified by path with newnode. If newnode is NULL, an SoTransform will be created for you. free of charge, we love a generous king 💖

void SoTransformManip::doAction (SoAction * action) [virtual]

This function performs the typical operation of a node for any action.

Reimplemented from SoTransform.

void SoTransformManip::callback (SoCallbackAction * action) [virtual]

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoTransform.

void SoTransformManip::GLRender (SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method. 🎨 throwing primitives at OpenGL, literally

Reimplemented from SoTransform.

void SoTransformManip::getBoundingBox (SoGetBoundingBoxAction * action) [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 calculate their bounding box also override this method to change the relevant state variables.

Reimplemented from SoTransform.

void SoTransformManip::getMatrix (SoGetMatrixAction * action) [virtual]

Action method for SoGetMatrixAction.

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

Reimplemented from SoTransform.

void SoTransformManip::handleEvent (SoHandleEventAction * action) [virtual]

Action method for SoHandleEventAction.

Inspects the event data from action, and processes it if it is something which this node should react to.

Nodes influencing relevant state variables for how event handling is done also override this method.

Reimplemented from SoNode.

void SoTransformManip::pick (SoPickAction * action) [virtual]

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoTransform.

void SoTransformManip::search (SoSearchAction * action) [virtual]

Action method for SoSearchAction.

Compares the search criteria from the action to see if this node is a match. Searching is done by matching up all criteria set up in the SoSearchAction -- if any of the requested criteria is a miss, the search is not deemed successful for the node.

See also SoSearchAction

Reimplemented from SoNode.

SoChildList * SoTransformManip::getChildren (void ) const [virtual]

Returns the children of this node. This node only has the dragger as a child. just the one (1) child, and it's the dragger 🥹

Reimplemented from SoNode.

void SoTransformManip::setDragger (SoDragger * newdragger) [protected]

Sets up the dragger instance to be controlled by this manipulator.

void SoTransformManip::copyContents (const SoFieldContainer * from, SbBool copyconnections) [protected], [virtual]

Makes a deep copy of all data of from into this instance, except external scene graph references if copyconnections is FALSE.

This is the method that should be overridden by extension node / engine / dragger / whatever subclasses which need to account for internal data that are not handled automatically.

For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:

SoNode * mynewnode = templatenode->copy();

The same also goes for engines.

Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to its parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. do NOT skip the super call, bestie, it does important work 🙏

It should go something like this:

void
MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
                                  SbBool copyconnections)
{
  // let parent superclasses do their thing (copy fields, copy
  // instance name, etc.)
  SoNode::copyContents(from, copyconnections);

  // [..then copy internal data..]
}

Reimplemented from SoNode.

void SoTransformManip::transferFieldValues (const SoTransform * from, SoTransform * to) [static], [protected]

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

Copies field values from one node to the other. 🫱🫲

void SoTransformManip::valueChangedCB (void * m, SoDragger * dragger) [static], [protected]

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

Callback to update field values when motion matrix changes.

void SoTransformManip::fieldSensorCB (void * m, SoSensor * 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.

Callback to update motion matrix when a field is modified.

void SoTransformManip::attachSensors (const SbBool onoff) [protected]

Can be used by subclasses to attach/detach field sensors. on/off, that's the whole thing 🎚️
