Post news Report article RSS Feed City 17: Episode 1 | 3 Day Update - Head Tracking & Ironsights

Using your head to play Video games. Literally.

Posted by MrtwovideoCards on Jun 21st, 2009

Headtracking has been around sometime now. We've seen the eyetoy for the Playstation 2, and soon Project Natal. What about that old web camera you have? It isn't about the camera itself, just the software that drives it, even this can make Project Natal feel dumb.

This is an Episode 1 Engine feature, and we are currently porting over all of the code to the Orange Box Engine. It's been a bit difficult, but we've been getting help from the creator himself. The main feature we plan to implement is 3D space, and much to that effect, a real time scopr which we already have in-game.

It's like 3D, without the glasses. All done via some extra code, and a 10$ to 20$ web camera. As seen in the video the API is pretty smart, we've gone through some code to help track your face within a 2 second time frame, so the API gets used to where you commonly bring your head back too.

We've also been hard at work at adding Ironsights to City 17, which give a more cinematic gameplay feeling, and overall improves the quality of gameplay.

Iron Sights

As an added bonus, you can also see our new water effects!

They all should, we're currently concentrating on 3d space first, as thats the best effect.

oh it will, the API especially, has no performance hit on the actual engine, and only requires resources based on your webcam, and their said rivers or apps to work.

the face api thing would be cool, for a multiplayer mod.
if it was possible to translate webcams data into ingame facial expressions, especially during voice chat.

I see that you are doing vertex manipulation for your new water effects and it looks very nice. Also I like your head tracking information.

I knew a guy who used the same software (or similar, I don't remember which) to allow him to look around a starfighter cockpit in SWG: Jump to Lightspeed...

Whatever you guys do, see that this feature is finished, this kind of interactivity is just TOO GOOD to let die!

Can't wait for this to come into full swing in the mod (or any current in-game incarnations if anyone can tell me where to get one)
