if (myObject.loaded) { ... }

parent

A reference to the parent SceneGroup containing the object

myParent = myObject.parent;

position

The position of the object as a Vector.

// set the position of the object to a known anchor

myObject.position = myAnchor3.position;

orientation

The rotational orientation of the object (as a Rotation).

// set the orientation of the object to a known anchor

myObject.orientation = myAnchor3.orientation;

transform

The Transform is the combined position and orientation of the object.

// set the transform of the object to a known anchor

myObject.transform = myAnchor3.transform;

worldSpacePosition

The worldSpacePosition of the object as a Vector.

// set the worldSpacePosition of the object to a known anchor

myObject.worldSpacePosition = myAnchor3.worldSpacePosition;

worldSpaceOrientation

The worldSpaceOrientation of the object (as a Rotation).

// set the worldSpaceOrientation of the object to a known anchor

myObject.worldSpaceOrientation = myAnchor3.worldSpaceOrientation;

worldSpaceTransform

The worldSpaceTransform is the combined worldSpacePosition and worldSpaceOrientation of the object.

// set the worldSpaceTransform of the object to a known anchor

myObject.worldSpaceTransform = myAnchor3.worldSpaceTransform;

Camera

The Camera module represents virtual cameras that are used to render a 2-D view from a 3-D SceneGroup. It has

properties that control the projection of the camera, such as ﬁ eld of view, position and orientation. There is a ﬂ ag that

may be used to lock the camera to the ﬁ rst person view from the actor, and a ﬂ ag that determines whether the avatar

is visible in the image generated by the camera. (This is useful when implementing third person camera controllers.)
