Detailed Description

\qmltype Object3D \inqmlmodule QtQuick3D \instantiates QQuick3DObject \inherits QtObject

Abstract base type of all 3D nodes and resources.

Object3D is the base class for all Qt Quick 3D types. This includes:

\list

  • Spatial types that represent objects in the 3D scene, these will normally have a position and/or a direction. For example, \l Model, \l Camera, or \l Light. Such types inherit from \l Node, which in turn inherits from Object3D.
  • Resource types that do not themselves represent an object in the 3D world, but rather serve as components to \l Node subclasses, providing data of some kind. This includes, among others, \l Material, \l Geometry, and \l Texture.

\endlist

In addition to the above types, Object3D can also serve as the parent for \l{Item}{Qt Quick items}, as well as arbitrary QObject instances. For more information on adding 2D items to the 3D scene, refer to \l{Qt Quick 3D Scenes with 2D Content}.

\inmodule QtQuick3D

Since
5.15

Base class of all 3D nodes and resources.

Object3D is the base class for all Qt Quick 3D scene objects. Currently the types available in C++ are:

\list

Both of these types are resource objects which directly inherit QQuick3DObject.

It should not be necessary to use QQuick3DObject directly anywhere currently because it is just an interface for supporting spatial items and resources in a 3D scene, as well as exposing similar functionality as QQuickItem for 3D scene content.

\qmlproperty Object3D QtQuick3D::Object3D::parent This property holds the parent of the Object3D in a 3D scene.

Note
An Object3D's parent may not necessarily be the same as its object parent. This is necessary because the object parent may be an item that is not of type Object3D, for example the root object in a scene.

Note
An Object3D's parent may not necessarily be the same as its object parent. This is necessary because the object parent may be an item that is not of type Object3D, for example the root object in a scene.
Currently for 3D items to be correctly handled by the scene manager when parenting 3D objects from C++ it is necessary to call QQuick3DObject::setParentItem before the QObject::setParent. This requirement is likely to change in a future release though.
