Not sure who downvoted the parent comment. Vouching for this, because: It seems the examples are using WebGL2, which (according to https://caniuse.com/#feat=webgl2 https://caniuse.com/#feat=webgl2 ) is only on by default in Chrome & Firefox (and can be enabled in Safari). So, if you're not seeing the examples, and you are _not_ using Chrome or Firefox, then you should try opening the site on that. P.S. I really do not want to start a discussion on features not being in some browsers or others.
