Let me start by complimenting on an awesome repository! It's what I was looking for, because I'm pretty sure I would have been trying to work out how to even get WebGL working in the first place.
When trying to prepend 'webgl2' to names[] in function create3DContext(), I kept getting the error "It does not appear your computer can support WebGL...". But I knew WebGL works in my browser, so after some trial and error I found that there was an itty-bitty bug in the code. It turns out that currently the 'experimental-webgl' is always selected, even if 'webgl' would return a valid context because the catch (e) is never reached to break out of the for loop.
Here's what I made of it:
function create3DContext(canvas, optAttribs)
{
var names = ['webgl2', 'webgl', 'experimental-webgl'];
var context = null;
for (var i = 0; i < names.length; ++i)
{
try
{
context = canvas.getContext(names[i], optAttribs);
if (context) break;
}
catch (e)
{
if (context) break; /// Can probably just leave this out all together.
}
}
return context;
}
Hope this helps.
Cheers.
PS: Wow, the code formatting (Insert code) realy made it unreadable 🤮. Have seen better on other sites.
