This project showcases the development of an AR application using the Unity Engine version 6. It serves as a comprehensive guide for building AR experiences, demonstrating key features such as face tracking, image tracking, and plane detection. Whether you're targeting iOS or Android platforms, this project provides step-by-step instructions and essential dependencies to get you started on your AR development journey.
Before you begin, ensure you have the following software installed:
- JetRider IDE: Required to open and edit the source code. You can download it from JetRider Official Website.
- Unity Engine version 6: Necessary for building and running the AR application.
Follow the installation instructions provided on the respective websites to set up these tools on your development machine.
This project relies on the following dependencies:
- Unity AR Foundation: Provides a framework for building AR applications.
- ARKit XR Plugin: Required for AR functionality on iOS devices.
- ARCore XR Plugin: Required for AR functionality on Android devices.
- XR Plug-in Management: Manages the loading of XR plugins and provides a unified interface for configuring and managing XR settings across different platforms.
- XR Simulation Environments: Allows testing and development of AR applications within a simulated environment, reducing the need for physical devices during the initial stages of development.
This project includes the following scenes, each demonstrating a specific AR feature:
- Description: This scene utilizes the front camera to detect and track facial features.
- How it works: When the app is launched, the AR Foundation framework processes the camera feed to identify and track facial landmarks. A green mask is then overlaid on the detected face to visualize the tracking.
- Description: This scene demonstrates the ability to recognize and track 2D images in the environment.
- How it works: The AR Foundation framework scans the environment for predefined images. Once an image is detected, the app overlays digital content on top of it, maintaining alignment as the image moves or the camera perspective changes.
- Description: This scene showcases the detection and tracking of horizontal and vertical planes in the environment.
- How it works: The AR Foundation framework analyzes the camera feed to identify flat surfaces. Detected planes are visualized with a grid pattern, allowing users to place virtual objects on these surfaces.
Each scene is designed to be a standalone demonstration of a specific AR capability, providing a clear and focused example of how to implement these features in your own AR projects.
