The returned coordinates all have their origin in the top left corner of the element. For container, the position is relative to the canvas element. For client, the position is relative to the canvas element, including the results of getBoundingClientRect. For page, the position is relative to the whole page.

Can be used in combination with viewableInAR to display a warning to use a different browser if viewableInAR is false and isMobileDeviceWithoutBrowserARSupport is true.
Reasons for that can be:
Pause the rendering of the scene. Can be used with continueRendering to continue/pause the rendering at will.
Calculate the ray that is created by the pointer event and the camera.
From the provided origin and direction, trace the ray through the scene. The intersections with GeometryData will be returned including the corresponding nodes, sorted by their smallest distance.

Restrict events. This can be used to disable events for a viewport.
Example use case: If you don't want to allow mouse wheel events for a specific viewport so that users can scroll past the viewport.
Be aware that this might cause some issues with the the camera controls if the pointer events are disabled only partially.

The new default material.
Update the default point material of the viewport.
The new default point material.
Update the position of the environment geometry (grid, groundplane, etc) to the current viewport bounding box. Internally, this functions is called whenever a session is customized, but if you manually change parts of the scene, it might get necessary to call this function. Make sure to call update before, to apply the last changes.
Update the viewport with the current changes of given scene tree node and its descendants. This carries out preparations for rendering. Call it after doing direct changes to the scene tree.

Optional callback that is called before the rendering of the scene.
The api for viewports.
Viewports are created by calling the createViewport method.
Each viewport has corresponding cameras and lights.
Additionally, there are various other settings to adjust the behavior and rendering of the viewport.
By default a new viewport displays the complete scene tree. Viewports can be excluded from displaying geometry for specific sessions by using the excludeViewports property of ISessionApi.
