Meta Quest SDK

Overview

The MultiSet Quest SDK is a Unity-based development kit designed specifically for Meta Quest headsets. It provides developers with seamless integration to MultiSet's Visual Positioning System (VPS), enabling precise real-time localization, pose visualization, and camera access within virtual and mixed reality applications.

What You Can Build

With the MultiSet SDK, you can create applications that:

• Track user position and orientation in real-world environments

• Anchor virtual objects to physical locations

• Build location-aware AR/VR experiences

• Implement spatial mapping and navigation systems

Key Capabilities

• Real-time Localization: Leverage MultiSet's VPS API for centimeter-accurate positioning

• Pose Visualization: Built-in 3D gizmos and world axes for debugging and development

• Camera Integration: Direct access to Meta Quest passthrough cameras

• Quest Optimization: Lightweight implementation optimized for Quest hardware

• Plug-and-Play: Minimal setup required for immediate integration

Getting Started

System Requirements

Before beginning development, ensure your system meets these requirements:

Development Environment:

• Unity 2022.3.58f1

• Android Build Support module installed

• Oculus XR Plugin (via Unity Package Manager)

Target Hardware:

• Meta Quest 3, 3S,

• Stable internet connection for VPS functionality

Installation Guide

Step 1: Download and Import SDK

1. Clone or download the MultiSet Meta Unity SDK :

2. Open Unity project

Step 2: Configure Unity Project Settings

1. Switch to Android Platform:

   • Go to File > Build Settings

   • Select "Android" and click "Switch Platform"

2. Configure XR Settings:

   • Go to Edit > Project Settings > XR Plug-in Management

   • Enable "Oculus" provider

   • Under "Oculus" settings, ensure Quest is selected as target device

3. Set Camera Permissions:

   • In Project Settings, go to Publishing Settings

   • Add camera permissions to the Android manifest

Step 3: Scene Setup

1. Open the SingleFrameLocalization Scene

Configuration

API Credentials Setup

Before using the SDK, you must configure your MultiSet API credentials:

1. Obtain Credentials:

   • Sign up at multiset.ai

   • Create a new project in your dashboard

   • Copy your Client ID and Client Secret

2. Configure in Unity:

   • Navigate to Assets/MultiSet/Scripts/MultiSetConfig.cs

   • Replace the placeholder values:

   csharppublic static string clientId = "YOUR_CLIENT_ID";public static string clientSecret = "YOUR_CLIENT_SECRET";

⚠️ Security Note: Never commit credentials to version control. Consider using Unity's ScriptableObject system for production deployments.

Map Configuration

Maps define the physical environments where your application will operate:

1. Select SDK Manager:

   • Find the MultisetSdkManager GameObject in your scene

   • Click to select it

2. Configure Map Settings:

   • In the Inspector panel, locate the MultiSet Localization Manager component

   • Enter your Map Code or Map Set Code

   • This determines which physical environment your app will localize against

3. Map Types:

   • Map Code: For single, specific locations

   • Map Set Code: For multiple related locations or larger areas

Camera Permissions

Ensure proper camera access by configuring Android permissions:

1. Automatic Configuration:

   • The SDK automatically adds required permissions

   • Verify in Assets/Plugins/Android/AndroidManifest.xml

2. Manual Configuration (if needed):

   xml<uses-permission android:name="android.permission.CAMERA" /><uses-feature android:name="android.hardware.camera" />
