WebGL presentation in WebGL

Most useful thing I got out of that:

Kinda fun. Though I'm getting a fair number of errors on the presets, only about 2/3 of them work properly.

edit: tried in Webkit + WebGL: nice whale. Is it really 80k triangles? Gotta love the render speed :)

Definitely more interesting in a WebGL browser, but could really have used more fun with that cube. It just seems... random. Like there wasn't enough 3D™ or something.

Older ATI card too? I’m getting problems with what looks like an nVidia extension on a fair few of these demos.

nVidia here, renders smooth as butter. Or other smooth things.

Hmm.. In Chrome space means "move 80% of a slide down" and space means "back to HN".

The title should be; A regular ol' HTML presentation about WebGL

View it again in a WebGL enabled browser:

Even using such a browser (Minefield 4.0b7), I get results that are best described as mixed on my machines when I view the presentation:

- MacBook running WinXP Pro via BootCamp - works fine

- Dell Inspiron 1110 running Win7 Home Premium - falls back to HTML version (gfx is Intel GMA 4500MHD, which claims to support OpenGL)

- Fedora 11 machine with nVidia drivers - works, but I get <10fps (CPU is Atom 330, gfx card is a PCI 8400GS)

- Fedora 12 machine with nouveau driver (gfx card is an ancient FX5200) - crashes browser

I'm sure I'm an atypical case, but are there any published stats on what proportion of machines out there should run WebGL if they have a capable browser?

Apparently Minefield is set up to require recent drivers. I was getting nothing on my laptop until I worked out that I had to go to intel's site, run the driver installer, ignore its error message telling me to go to the laptop manufacturer, and manually tell windows to use the driver now in my temp folder.
