Detailed Description

Abstract base class for 3D object interface.

This base class defines the interface that run-times can implement to provide basic 3D object behavior. 3D objects have visibility, and have 3D space bounds.

To avoid the memory-consuming "one proxy object per scene object" approach, Object3d interface objects should be obtained and used within a local scope, and not stored. Object3d interfaces should be considered stateless, and can be bound to new selection items.

Constructor & Destructor Documentation

Object3d() [1/2]

Ufe::Object3d::Object3d

(

)

Constructor.

Object3d() [2/2]

Ufe::Object3d::Object3d ( const Object3d &  )

default

Default copy constructor.

~Object3d()

virtual Ufe::Object3d::~Object3d ( )

virtual

Destructor.

Member Function Documentation

addObserver()

static bool Ufe::Object3d::addObserver ( const Observer::Ptr &  obs )

static

Add observation for Object3d changes on any item in the scene (global observation).

Parameters

obs	Observer to add.

Returns

True if the observer is added. Add does nothing and returns false if the observer is already present.

boundingBox()

virtual BBox3d Ufe::Object3d::boundingBox ( ) const

pure virtual

Return the local space, axis-aligned 3D extents of the object.

Returns

Object bounding box.

hasObserver()

static bool Ufe::Object3d::hasObserver ( const Observer::Ptr &  obs )

static

Query observation for Object3d changes on any item in the scene (global observers).

Parameters

obs	Observer to query.

Returns

True if the observer observes Object3d changes on any item in the scene.

nbObservers()

static std::size_t Ufe::Object3d::nbObservers ( )

static

Number of observers for Object3d changes on any item in the scene (global observers).

Returns

Number of observers.

notify()

static void Ufe::Object3d::notify ( const Notification &  notif )

static

Notify all global observers. The order in which observers are notified is unspecified. If no observer exists, does nothing.

Parameters

notif

The Object3d notification to send.

object3d()

static Ptr Ufe::Object3d::object3d ( const SceneItem::Ptr &  item )

static

Convenience method that calls the object3d method on the Object3d handler for the item. Returns a null pointer if the argument is null, or has an empty path.

Parameters

item	SceneItem for which Object3d interface is desired.

Returns

Object3d interface of the given SceneItem.

removeObserver()

static bool Ufe::Object3d::removeObserver ( const Observer::Ptr &  obs )

static

Remove observation for Object3d changes on any item in the scene (global observation).

Parameters

obs	Observer to remove.

Returns

True if the observer is removed. False if the observer isn't found.

sceneItem()

virtual SceneItem::Ptr Ufe::Object3d::sceneItem ( ) const

pure virtual

Scene item accessor.

setVisibility()

virtual void Ufe::Object3d::setVisibility ( bool  vis )

pure virtual

Set the visibility state of the object.

setVisibleCmd()

virtual Ufe::UndoableCommand::Ptr Ufe::Object3d::setVisibleCmd ( bool  vis )

pure virtual

Create an undoable visible command.

visibility()

virtual bool Ufe::Object3d::visibility ( ) const

pure virtual

Return the visibility state of the object.

Returns

true if the object is visible
