Properties
StaticDefaultVector3(0, 1, 0)
Every objects in 3D space must have a default up direction.
id
Unique number for each object3D instance.
scene

update-1
The number is the frame id which this object is changed or participates change of scene graph. If this value equals to frame id - 1,
name

Record when this object's world matrix last updated.
transform
Record whether the object's any attribute| attribute is updated.
visible
matrix

worldtrue
Mark bounding need to be recalculated.
world
Calculate the bounding as box.
world
Calculate the bounding as sphere.
z
The distance from object to camera in the direction of camera. Use this value to simply estimate the depth in 3D scene.
on
