Class ViewObject

An object within a View.

Proxies a SceneObject and controls its visual state in the View.
Stored in View.objects and ViewLayer.objects.
Viewer automatically creates one of these in each View whenever a SceneObject is created.
SceneObject.layerId optionally specifies a ViewLayers to put the ViewObject in.

Overview

Every View automatically maintains within itself a ViewObject for each SceneObject that exists in the Viewer.

Whenever we create a SceneObject, each View will automatically create a corresponding ViewObject within itself. When we destroy a SceneObject, each View will automatically destroy its corresponding ViewObject. The ViewObjects in a View are therefore a manifest of the ViewerObjects in the View.

See @xeokit/sdk/viewer for usage.
