onBeginRender Readonly

onBeginRender: BeEvent<() => void> = ...

Called at the beginning of each tick of the render loop, before any viewports have been updated. The render loop is typically invoked by a requestAnimationFrame() callback. It will not be invoked if the ViewManager is tracking no viewports.

note Due to the frequency of this event, avoid performing expensive work inside event listeners.
