Hardware and Software Requirements for the Threshold 360 Player

The Threshold 360 Platform uses a variety of web standards, but primarily WebGL (Web Graphics Library).

See below for details of this programming interface as well as other tips for making your hardware and software for the Threshold 360 Player run smoothly.

Web GL

Web GL is a JavaScript API for rendering interactive 3D and 2D graphics within any compatible web browser, all without the use of plug-ins. WebGL accomplishes this by introducing an API that closely conforms to OpenGL ES 2.0, and that can be used in HTML5 elements.

WebGL and its libraries are supported by all current web browsers. However, the site visitor's device hardware must also support WebGL features in order for it to run smoothly.

Hardware Support for Web GL

Most browsers use your device's graphics card (GPU) to speed up the display of web content. WebGL and other advanced features also use graphic cards to perform calculations. If a GPU is not there, WebGL might use the CPU, which also slows the overall experience of the web page / virtual tour. Make sure to update your graphics card drivers in order to solve problems with these features, or to take full advantage of them.

Other things to do if you encounter issues

1. Check to see if WebGL is supported. In your current browser, visit this url: https://get.webgl.org/. Or, you can download this file to test individual browsers for WebGL.
2. Use any other browser installed on your computer. Each browser uses individual settings to determine if WebGL is supported on your computer. So, if Chrome blocks it, try Firefox.
3. Update your browser to the latest version. In order for the Threshold 360 player displays properly, ensure you are running the most up-to-date version of your web browsers by visiting What is My Browser.
