Support for Meta Quest 3

[sujathasperi2022]

Am developing an app for Meta Quest 3 using viro.

Below is the code I tried.

import {
  ViroARScene,
  ViroARSceneNavigator,
  ViroScene,
  ViroText,
  ViroTrackingReason,
  ViroTrackingStateConstants,
  ViroVRSceneNavigator,
} from "@reactvision/react-viro";
import React, { useState } from "react";
import { StyleSheet } from "react-native";

const HelloWorldSceneAR = () => {
  const [text, setText] = useState("Initializing AR...");

  function onInitialized(state: any, reason: ViroTrackingReason) {
    console.log("onInitialized", state, reason);
    if (state === ViroTrackingStateConstants.TRACKING_NORMAL) {
      setText("Hello World!");
    } else if (state === ViroTrackingStateConstants.TRACKING_UNAVAILABLE) {
      // Handle loss of tracking
    }
  }

  return (
    <ViroARScene onTrackingUpdated={onInitialized}>
      <ViroText
        text={text}
        scale={[0.5, 0.5, 0.5]}
        position={[0, 0, -1]}
        style={styles.helloWorldTextStyle}
      />
    </ViroARScene>
  );
};

export default () => {
  return (
    <ViroARSceneNavigator
      autofocus={true}
      initialScene={{
        scene: HelloWorldSceneAR,
      }}
      style={styles.f1}
    />
  );
};

var styles = StyleSheet.create({
  f1: { flex: 1 },
  helloWorldTextStyle: {
    fontFamily: "Arial",
    fontSize: 30,
    color: "#ffffff",
    textAlignVertical: "center",
    textAlign: "center",
  },
});

This is how it looks in android phone

When I run in MQ3

UPDATE 10 Jul 2024 12.31 PM

the on initialized function return as

onInitialized 1 1

state is 1 which means ViroTrackingStateConstants.TRACKING_UNAVAILABLE
reaon is 1 which means ViroARTrackingReasonConstants.TRACKING_REASON_NONE

state value one means AR Camera position is not available.
