In this tutorial, we will guide you through adding contextual comments to a Matterport SDK application using SuperViz. Contextual comments enable users to leave feedback directly within a 3D model, making it easier to collaborate on design reviews, walkthroughs, and virtual tours. This feature is particularly useful in scenarios where precise feedback within a spatial context is critical.
We'll demonstrate how to integrate SuperViz with Matterport, allowing participants to add and view comments within the 3D environment in real-time. By the end of this tutorial, you'll have a fully functional Matterport application with a robust commenting system that enhances collaboration and communication.
Let's get started!
Prerequisite
To follow this tutorial, you will need a SuperViz account and a developer token. If you already have an account and a developer token, you can move on to the next step.
Create an Account
To create an account, go to https://dashboard.superviz.com/register and sign up using either Google or an email/password. Note that if you choose email/password, you will receive a confirmation link that you'll need to click to verify your account.
Retrieving a Developer Token
To use the SDK, you’ll need a developer token, which is essential for associating SDK requests with your account. You can retrieve both development and production SuperViz tokens from the the dashboard.
Copy and save the developer token, as you will need it in the next steps of this tutorial.
Step 1: Set Up Your React Application
To begin, you'll need to set up a new React project where we will integrate SuperViz and the Matterport SDK.
1. Create a New React Project
First, create a new React application using Create React App with TypeScript.
npm create vite@latest matterport-comments -- --template react-ts
cd matterport-comments
2. Install Required Libraries
Next, install the necessary libraries for our project:
npm install @superviz/sdk @superviz/matterport-plugin uuid
- @superviz/sdk: For integrating real-time collaboration features, including comments.
- @superviz/matterport-plugin: Plugin for adding SuperViz interaction features to a Matterport Viewer.
- uuid: A library for generating unique identifiers, useful for creating unique participant IDs.
3. Set Up Environment Variables
Create a .env file in your project root and add your SuperViz developer key and Matterport application key. These credentials will be used to authenticate your application with SuperViz and Matterport services.
VITE_SUPERVIZ_API_KEY=YOUR_SUPERVIZ_DEVELOPER_KEY
VITE_MATTERPORT_KEY=YOUR_MATTERPORT_KEY
Step 2: Implement the Main Application
In this step, we'll implement the main application logic to initialize SuperViz and the Matterport Viewer, and handle real-time contextual comments.
1. Implement the App Component
Open src/App.tsx and set up the main application component using SuperViz to manage the collaborative environment.
import { v4 as generateId } from 'uuid';
import { useCallback, useEffect, useRef } from "react";
import SuperVizRoom, { Comments } from '@superviz/sdk';
import { MatterportPin } from '@superviz/matterport-plugin';
import type { MpSdk } from '@superviz/matterport-plugin/dist/common/types/matterport.types.d.ts';
Explanation:
- Imports: Import necessary components from React, SuperViz, Matterport Plugin, and UUID for managing state, initializing SuperViz, and enabling contextual comments within the Matterport SDK.
2. Define Constants
Define constants for the API key, Matterport key, and room ID.
const apiKey = import.meta.env.VITE_SUPERVIZ_API_KEY as string;
const matterportKey = import.meta.env.VITE_MATTERPORT_KEY as string;
const ROOM_ID = 'matterport-comments';
const PLAYER_ID = generateId();
Explanation:
- apiKey & matterportKey: Retrieves the SuperViz and Matterport API keys from environment variables.
- ROOM_ID & PLAYER_ID: Defines the room ID for the SuperViz session and generates a unique player ID.
3. Create the App Component
Set up the main App component and initialize references for the Matterport SDK.
export default function App() {
const matterportSDK = useRef<MpSdk | null>(null);
useEffect(() => {
initializeMatterport();
}, []);
}
Explanation:
- matterportSDK: A ref to store the Matterport SDK instance.
-
useEffect: Calls the
initializeMatterportfunction once when the component mounts, setting up the Matterport Viewer.
4. Initialize SuperViz
Create a function to initialize SuperViz and integrate the contextual commenting system.
const initializeSuperViz = useCallback(async () => {
const superviz = await SuperVizRoom(apiKey, {
roomId: ROOM_ID,
participant: {
id: PLAYER_ID,
name: 'player-name',
},
group: {
id: 'matterport-comments',
name: 'matterport-comments',
}
});
const pinAdapter = new MatterportPin(matterportSDK.current!, document.getElementById('showcase')!);
const comments = new Comments(pinAdapter, {
buttonLocation: 'top-right',
});
superviz.addComponent(comments);
}, []);
Explanation:
- initializeSuperViz: An asynchronous function that initializes SuperViz and adds the contextual comments component to the Matterport Viewer.
- MatterportPin: Adapts the Matterport SDK to work with SuperViz's commenting system, allowing users to pin comments directly in the 3D space.
5. Initialize Matterport Viewer
Create a function to initialize the Matterport Viewer with the necessary credentials and configurations.
const initializeMatterport = useCallback(async () => {
const showcase = document.getElementById('showcase') as MatterportIframe;
const showcaseWindow = showcase.contentWindow as MatterportIframe['window'];
const source = \`/vendor/matterport/showcase.html?&play=1&qs=1&applicationKey=\${matterportKey}&m=Zh14WDtkjdC\`;
showcase.setAttribute('src', source);
await new Promise((resolve) => {
showcase.addEventListener('load', async () => {
matterportSDK.current = await showcaseWindow?.MP_SDK.connect(showcaseWindow, matterportKey);
resolve(matterportSDK.current);
});
});
initializeSuperViz();
}, [initializeSuperViz]);
Explanation:
- initializeMatterport: Loads the Matterport Viewer in an iframe, connects the Matterport SDK, and then initializes SuperViz for real-time collaboration and commenting.
Step 3: Render the Application
Finally, return the JSX structure for rendering the Matterport Viewer and the SuperViz-powered interface.
return (
<div className='w-full h-full bg-gray-200 flex items-center justify-center flex-col'>
<header className='w-full p-5 bg-purple-400 flex items-center justify-between'>
<h2 className='text-white text-2xl font-bold'>SuperViz Matterport Comments</h2>
</header>
<main className='w-full h-full flex items-center justify-center relative'>
<iframe id='showcase' className='w-full h-full' />
</main>
</div>
);
Explanation:
-
Viewer Container: The
showcaseiframe is where the Matterport Viewer will be rendered, filling the entire screen. This is where users will interact with the 3D space and collaborate in real time with contextual comments.
Step 4: Understanding the Project Structure
Here's a quick overview of how the project structure supports adding contextual comments to a Matterport SDK application:
-
App.tsx- Initializes SuperViz.
- Sets up the Matterport Viewer with real-time commenting features.
- Handles the loading of 3D spaces and integration of collaborative tools.
-
Matterport Viewer
- Renders the 3D space, allowing users to navigate, inspect, and leave comments in a shared virtual environment.
-
SuperViz Components
- MatterportPin & Comments: Enables users to pin comments to specific locations in the 3D model, enhancing collaborative review sessions.
Step 5: Running the Application
1. Start the React Application
To run your application, use the following command in your project directory:
npm start
This command will start the development server and open your application in the default web browser. You can interact with the 3D space and see real-time comments from other participants.
2. Test the Application
- Contextual Comments: Open the application in multiple browser windows or tabs to simulate multiple participants and verify that comments are updated in real-time.
- Collaborative Interaction: Test the commenting feature by adding comments to the 3D model and observing how they appear for other participants.
Summary
In this tutorial, we integrated contextual comments into a Matterport SDK application using SuperViz. We configured a React application to handle 3D space navigation and commenting, enabling multiple users to collaborate seamlessly within a shared virtual environment. This setup can be extended and customized to fit various scenarios where real-time collaboration on 3D spaces is required.
