Translated the README for the THETA_GL repo by mganeko. This is a THETA WebGL Viewer using three.js, a Javascript 3D library. This should make it more accessible to THETA :theta: developers who don’t speak Japanese.

Comments, edits, questions welcome!

THETA_GL

THETA WebGL Viewer using three.js (Javascript 3D library)

[Many thanks to mganeko for this useful repo! This English translation of the README.md file for mganeko’s THETA_GL repo provided by the RICOH THETA Unofficial Guide. Original Japanese language README.md file information is appended below. This is provided “as-is and unofficial." Comments and edits welcome. More information on useful GitHub repos for the RICOH THETA curatated by the RICOH THETA Unofficial Guide here]

Acknowledgments

  • In order to render WebGL, three.js is used

    • To show rendering of full photospheres, samples of panoramas / equirectangular are referenced
    • three.js is covered under the MIT license
  • In order to handle UV Mapping, the following data was utilized:

  • Using anzu-sdk.js from the WebRTC SFU as a Service called Anzu, a WebRTC distribution service

    • The Anzu WebRTC SFU as a Service is provided by the company Shiguredo, K.K. (Japan)
    • anzu-sdk.js is under the Apache License Version 2.0

Thank you, everyone.

Operating Environment

I have tested and confirmed the following operating environment:

  • Chrome 47.0.2526.106 (64-bit) for MacOS X
  • Firefox 43.0.3 for MacOS X
  • Chrome 47.0.2526.106 m for Windows
  • Firefox 43.0.2 for Windows
  • Chrome for Android
  • Firefox for Android

Maybe because Firefox for Android uses m4v format, playback for recorded video files is not possible.

[Translator’s Note: This section of links appears to need an account with this service, and this section of links do not appear to work.]

Usage

Prep

  • Load three.js and three.min.js in HTML
  • Load theta_gl.js in HTML
    • You must have the JSON file in the UV folder when you use it
  • When you use Anzu, anzu.js or anzu.min.js is required

Initialization

  • THETA_GL.init(divId, autoResuze, debugFlag)
    • string divId: It will be a Canvas container displaying WebGL, set the div element ID [REQUIRED]
    • bool autoResize: Comply with window resize or not (true/false) - default is true
    • bool debugFlag: For debugging, running video elements or displaying canvas elements, or displaying log information in the console - default is false

Starting WebGL Animation

  • THETA_GL.startAnimate()

Setting the source URL of videos

  • THETA_GL.setVideoSrc(url, loopFlag)
    • string url: URL for videos. Use a web URL or set a URL created with URL.createObjectURL() [REQUIRED]
    • bool loopFlag: Run the video in a loop or not (true/false) - default is false

Stopping Video

  • THETA_GL.stopVideoSrc()

Setting Device Orientation

  • THETA_GL.followOrientation(flag)
    • bool flag: Setting whether to follow the smart device orientation or not. [REQUIRED]

var url = 'http://yourserver.com/video.mp4';
THETA_GL.init('container', true, false);
THETA_GL.setVideoSrc(url, true);
THETA_GL.startAnimate();

Thanks. Is it only for prerecorded video files or does it support live streaming through the THETA USB? There’s the interesting section heading, Connecting to USB Camera, but the sample link is blank. There’s also reference to this Anzu WebRTC SFU as a Service. Were you able to figure out what that is?

There’s this tantalizing picture:

I’m primarily interested because it seems like it may be connected to the WebRTC sample code from RICOH.
