Samples available on main page are not working. When I try to Run/Debug then execution is failed with message about missing glMatrix-0.9.5.min.js file. Please update your samples.
Thanks we reproduced this issue, the main page WebGL link is broken.
Please select WebGL sample implicitly from the drop-down list in top-right corner.
We used to have this issue a long time ago, now WebGL sample points to
var script = document.createElement("script");
script.src = "http://duoco.de/assets/js/glMatrix-0.9.5.min.js";
and this file is hosted by us and present.
