C Specification

The XrSceneMeshTrackingStateANDROID enumeration describes the tracking state for a scene meshing tracker. Each value in this enum represents a state of the scene meshing tracker.

// Provided by XR_ANDROID_scene_meshing
typedef enum XrSceneMeshTrackingStateANDROID {
    XR_SCENE_MESH_TRACKING_STATE_INITIALIZING_ANDROID = 0,
    XR_SCENE_MESH_TRACKING_STATE_TRACKING_ANDROID = 1,
    XR_SCENE_MESH_TRACKING_STATE_WAITING_ANDROID = 2,
    XR_SCENE_MESH_TRACKING_STATE_ERROR_ANDROID = 3,
    XR_SCENE_MESH_TRACKING_STATE_MAX_ENUM_ANDROID = 0x7FFFFFFF
} XrSceneMeshTrackingStateANDROID;

Description

The enumeration values have the following meanings:

Enum Description

XR_SCENE_MESH_TRACKING_STATE_INITIALIZING_ANDROID

The tracker is not yet ready to provide mesh data.

XR_SCENE_MESH_TRACKING_STATE_TRACKING_ANDROID

The tracker is actively tracking.

XR_SCENE_MESH_TRACKING_STATE_WAITING_ANDROID

The tracker is waiting for valid measurements to integrate since the last mesh update.

XR_SCENE_MESH_TRACKING_STATE_ERROR_ANDROID

The tracker has not received valid measurements for multiple cycles and is in an error state.

This state serves only as additional information to the application. In the absence of other sources of errors, the runtime must continue to allow the application to create snapshots and retrieve data from them regardless of the current XrSceneMeshTrackingStateANDROID of the tracker. If the state is not XR_SCENE_MESH_TRACKING_STATE_TRACKING_ANDROID, the snapshots may not be up to date or empty.
