Label: string;

Scene name.

Children

Children: SceneNode[] = [];

List of all elements in the scene graph.

MainCamera

MainCamera: Camera | undefined;

Camera from the point of view of which the scene will be rendered.

Constructors

new Scene(label?): Scene;

Parameters

Parameter	Type	Default value	Description
label?	string	"Scene"	Scene name.

Returns

Scene

Parameters

Parameter	Type	Description
children	SceneNode | SceneNode[]	Element(s) to add.

Returns

void

Remove()

Remove(children): void;

Remove any Mesh, Shape or SceneNode element(s) from the scene graph. Only unlinking is performed, the Destroy method on removed element(s) is not called.

Parameters

children	SceneNode | SceneNode[]	Element(s) to remove.

Returns

void

AddMainCamera()

AddMainCamera(camera): void;

Add a Camera as a child of the scene and assign it to the MainCamera property. To switch to a different camera, simply assign it to the MainCamera member.

camera	Camera	Camera to use.

Returns

void

See

Cameras / UV Mapping for reference.

UpdateWorldMatrix()

UpdateWorldMatrix(): void;

Update local and world matrices of all elements in the scene graph. Its use is discouraged since this method is called internally on every render.

Returns

void

Traverse()

Traverse(callback): void;

Perform the callback function on every element of the scene graph. The scene itself will be excluded from the iteration.

Parameters

Parameter	Type	Description

void

Accessors

WorldMatrix

Get Signature

get WorldMatrix(): Float32Array<ArrayBufferLike>;

Returns

Float32Array<ArrayBufferLike>

The world matrix of the scene. Its use is discouraged since this getter is called internally when updating the camera's view projection matrix.
