Creating a 360-Degree Viewer Inside Unity

In this tutorial, we will delve into creating a 360 viewer inside Unity, enabling users to experience immersive videos. The process involves setting up a video player, render texture, materials, camera script, and a user interface for a seamless viewing experience.

Setting Up the 360 Viewer

Adding a Video Player Component

  • Right-click in Unity, navigate to Video, and select Video Player.
  • Check the loop box to enable video looping.
  • Ensure the render mode is set to render texture.

Creating a Render Texture

  • Under Create, generate a Render Texture named 'render texture 360 video' with dimensions matching the video (e.g., 4096 x 2048).
  • Create a material named '360 materials' and change its shader to 'Skybox Panoramic.'

Applying Materials and Videos

  • Assign the render texture to the material.
  • Drag the video texture into the Video Player's target texture.

Implementing Camera Rotation

  • Develop a simple script for camera rotation allowing users to look around the scene by clicking and dragging the camera.

Video Manager Setup

Creating Video Manager Methods

  • Establish a Video Manager with methods for play, pause, stop, and loading videos from URLs or local files.
  • Set up events to trigger actions such as playing the video upon preparation completion.

User Interface Integration

  • Design user interface elements using Unity's Canvas feature.
  • Add buttons for play, pause, and stop functionalities, linking them to the Video Manager methods.

Loading Videos

  • Incorporate an input field for URLs, enabling users to load videos by providing a video link.
  • Enable users to interact with the interface to play, pause, or stop the video seamlessly.

Virtual Reality Integration

Enabling VR Support

  • To make the application VR-ready, navigate to Edit > Project Settings > Player.
  • Check the 'Virtual Reality Supported' box and set the Virtual Reality SDK to Oculus and OpenVR for compatibility with Oculus Rift and HTC Vive.

By following these steps, users can create an interactive 360 viewer in Unity, enhancing their video viewing experience. Whether using a mouse or VR headset, the viewer can navigate, pause, play, and stop videos seamlessly.
