Perhaps I read the wrong sorts of blogs but I haven’t seen this 3D Flash demo picked up anywhere yet.

The makers of the ‘Alternavita’ platform have managed to create a large scale 3D environment for use in browser windows that’s somewhere in between PSOne and PlayStation 2 texture quality and polygon count.

It’s incredible. If you’re running Flash Player 9 then head over here and, if you’re running Flash Player 10 beta then head over here (if you’re not sure which one you’ve got then you almost certainly aren’t running 10 yet).

Both versions add a kiloton of weight to the argument that, while PC gaming might be curling up in a quiet corner in the traditional sense, browser-based gaming is a solidifying future of gaming.

Jim Rossignol wrote a fantastic piece on RPS this week about what some time spent away from the Internet taught him about the way its embedded itself in his life.

He’s talking almost exclusively about information here but, using the reasons he identifies for why the web has become something of a prosthetic brain, it’s easy to see how having the internet as the future’s consolidated gaming platform makes complete sense.

If Xbox Live and PSN are mutant microcosms of the Internet, at least in terms of connectivity, integration and persistence (i.e. the services are always on) then, once Flash starts to match the technical oomph of the current crop of home consoles, the case for moving over to a single, virtual software platform becomes irrefutable.

Of course, we might need to wait till Flash Player 12 before we get anywhere near the graphical showboating in this sort of thing, but as Alternavita’s tech demos demonstrate, every month the gap is closing.
