Configuring Linux systems to support AR/VR and augmented reality development

Introduction:
With the development of augmented reality (AR) and virtual reality (VR) technology, more and more developers Start paying attention to these emerging areas. For AR/VR and augmented reality development, it is very important to configure your Linux system correctly. This article will introduce you to how to configure a Linux system to support AR/VR and augmented reality development, and provide corresponding code examples.

Step 1: Install the necessary software

Before you start, please make sure your Linux system has the following software installed:

1. Unity3D: Unity3D is a Powerful AR/VR and augmented reality development tools. You can download and install Unity for Linux from the Unity official website (https://unity3d.com).
2. ARCore/ARKit: ARCore (for Android devices) and ARKit (for iOS devices) are the two mainstream AR platforms. You can download and install the corresponding development package according to the guidelines of the official documentation.
3. SteamVR: SteamVR is a tool for VR development. Before installing SteamVR, please make sure your system has the Steam client installed. You can then download and install SteamVR on Steam.

Step 2: Configure the AR development environment

First, we need to configure the AR development environment. Taking ARCore as an example, the following are the steps to configure the ARCore development environment:

1. Download the ARCore development package:

   $ wget https://github.com/google-ar/arcore-android-sdk/releases/download/v1.17.0/arcore-android-sdk-1.17.0.tar.gz

2. Unzip the downloaded development package ：

   $ tar -xvzf arcore-android-sdk-1.17.0.tar.gz

3. Move the unzipped folder to the installation directory you want:

   $ mv arcore-android-sdk-1.17.0 ~/arcore-sdk

4. Set environment variables:

   Open your terminal configuration file (for example: .bashrc) and add the following:

   export ARCORE_HOME=~/arcore-sdk
   export PATH=$PATH:$ARCORE_HOME/Tools

5. Enable environment variables to take effect:

   $ source ~/.bashrc

The process of configuring the AR development environment is similar. You only need to download and configure the corresponding development package according to the corresponding AR platform.

Step 3: Configure the VR development environment

Next, we need to configure the VR development environment. The following are the steps to configure the SteamVR development environment:

1. Install SteamVR:

   Open the Steam client, search and install SteamVR.

2. Create a Unity project:

   Open Unity3D and create a new project. In the project settings, enable the SteamVR plugin.

3. Import SteamVR plug-in:

   Open "Assets" in the Unity menu, select "Import Package" -> "Custom Package", and then select the SteamVR you downloaded Development package is imported.

4. Configure the Unity project:

   In Unity, open the SteamVR settings panel. You can set up and configure your VR input device by selecting "Window" -> "SteamVR Input".

5. Start VR development:

   Now that you have completed the configuration of the VR development environment, you can start writing your own VR applications.

Summary:
Through the above steps, you have successfully configured your Linux system to support AR/VR and augmented reality development. Whether it’s AR or VR, with proper configuration and the use of appropriate development tools, you can easily create stunning AR/VR and augmented reality applications. Come on, friends!

Appendix: Code Example

The following is a simple Unity script example for displaying the video stream from an ARCore camera:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ARCameraController : MonoBehaviour
{
    void Start()
    {
        Application.RequestUserAuthorization(UserAuthorization.WebCam);
    }

    void Update()
    {
        if (Application.HasUserAuthorization(UserAuthorization.WebCam))
        {
            for (int i = 0; i < WebCamTexture.devices.Length; i++)
            {
                WebCamTexture webcamTexture = new WebCamTexture(i, 1280, 720, 30);
                Renderer renderer = GetComponent<Renderer>();
                renderer.material.mainTexture = webcamTexture;
                webcamTexture.Play();
            }
        }
    }
}

The above code example is obtained using Unity's WebCamTexture class ARCore camera's video stream and draws the video stream onto the object's material.

I hope that through these sample codes, you can better understand the process of AR/VR and augmented reality development and be able to apply it to your own projects.
