Abstract: Aspects of the subject technology provide for system state management in a centralized rendering environment. A system may initialize a tree structure for a three-dimensional environment. The system renders the three-dimensional environment based at least in part on a traversal of the tree structure. The system identifies a request to change first or second visual states. The system can determine a first state update to the first visual state and a second state update to the second visual state and updates the tree structure by passing, by a first node, the first state update to a first child node and separately passing the second state update to a second child node. The system re-renders the three-dimensional environment based at least in part on a traversal of the updated tree structure.

Abstract: Facilitating the fit of a head mounted device includes calculating a nominal interocular distance (IOD) using a nominal eye model. A device IOD is based on a distance between a first optical module and a second optical module of the headset. The device IOD is compared to the calculated nominal IOD. If a difference between the device IOD and the calculated nominal IOD satisfies a threshold, an adjustment process is initiated to modify the distance between the first optical module and the second optical module.
