You must use Dartium (Version 50 or later) and Dart SDK (Version 1.24.0 or later)

Create a new Dart webapp project, add this as a pubspec.yaml dependency: dependencies: chronosgl: any

You also need the vector_math library which is the only library that ChronosGL is dependent on.

Copy the example from above and run it in Dartium.

It should look like this: <img src="" style="width: 600px;"/>

If you need dart:html, it is recommended to add dart:html as HTML like this, due to a naming conflict regarding Node: import 'dart:html' as HTML;
