afterRender :Array
-
An array of functions to be called at the end of the frame. This array will be cleared after each frame.

updatefunctions and firing them at a time when the subscribers are free to change the scene state, e.g., manipulate the camera, instead of firing events directly inupdatefunctions.Example
frameState.afterRender.push(function() { // take some action, raise an event, etc. }); -
