Your platform does not support the draw buffers extension. This demo won't run in your browser. #2

Tried running this on windows, in chrome and firefox, and got this error in both. I was able to compile the shaders, so I don't think that is the issue. Am I supposed to use Mac/Linux to run this, or have you been able to run it on Windows?

The demo should run on Windows (I run Windows personally), but it does rely on the WEBGL_draw_buffers extension, which enjoys poor browser support. Draw buffers may be unsupported because of your hardware, your driver version or your browser version.

Unfortunately, I did not find a way to achieve this demo without multiple render outputs, and the extension support is out of my control.

Can you tell me which OS and browser you did get it to run on?

Does that mean it doesn't run? I don't know GL very well, I just wanted to play with this thing.

I've run it on Chrome 48.0.2564.103, Windows 7 as well as Windows 8. Earlier Chrome versions seemed to work as well, although I don't know how far back.

Does that mean it doesn't run?

Unfortunately, yes. I'm not entirely too happy about it either - sadly, WebGL is still in its infancy and will need some time to catch up with Desktop GL.

This might also depend on your graphics card and the version of its drivers, since the browser can only offer the extensions the driver implements.

For posterity, the demo would not run on my home computer(windows 7, chrome 48, Nvidia 760), but did run on my work PC(different GPU, some sort of AMD). I was a bit confused when you said you've run it and also that it doesn't run.
