Why not use something like "recorddemo DEMONAME, stoprecording, playdemo DEMONAME, avidemo DEMONAME" in Doom3, then convert it to a video? No extra lag by any software, video convertion or hdd IO trying to record a video at the same time the computer is rendering it.cybereality wrote:Also, just note that FRAPS for some reason introduced serious lag/delay in the head-tracking so this made it not as smooth as normal.
3dvision supports checkerboard because of the launch Mitsubishi TV's, which needed a way to claim to support 1080p 3d on the old HDMI standard.

Have no clue if this could be converted to side-by-side fast enough to be used . . . 2EyeGuy wrote:What on Earth are you talking about?bobjwatts wrote:@2EyeGuy - Does it do the split blue/red style 3d that is in the youtube video, on top of the standard side-by-side.
Cybereality's Vireio Perception driver might support blue/red style 3d glasses for people who don't have an Oculus Rift.
But if you are talking about the Oculus Rift (Virtual Reality Head Mounted Display), then you aren't making any sense, and I think you completely misunderstand something.
Not sure if BlackShark is describing this correctly, but he brings up a good point. Cyber, have you given some thought to head and neck models? I assume right now for simplicity you are using a simple camera rotate. But the center of rotation dramatically effects the look of the transform. I used one of Carmack's earlier head models where it seems like he modeled rotation around the nose. So when I rolled my head around the chin (flopped my head onto my shoulder) it creating an eerie shearing effect on the world that broke the illusion of reality - or at least made it look like I was on drugs. It was really striking how different the world looked when I switched between nose and chin rotations. Anyway, just a head's up to think about this. It's possible the Oculus SDK may even include a configurable head and neck model for their tracker values which would be convenient to use and would provide some consistency to many Rift games.BlackShark wrote:The 6DOF head tracking thing is nice, but it looks really weird in the video, whenever you turn your head it feels as if everything is heavily distorted.

On a regular 3D display, the display doesn't follow your eyes, so when you tilt your head you'll also have to tilt the interocular vector to match the position of the viewer. Finally : some 3D displays don't support head tilt, so you might need to provide an option to lock head tilt (provide only 5DOF instead of 6)
Yeah, it's just tricking into generic dlp. As far as I understand the checkerboard is just LRLR pattern so converting to SBS is just a question about separating odd and even pixels. Or maybe i'm missing somethingrowanunderwood wrote:3dvision supports checkerboard because of the launch Mitsubishi TV's, which needed a way to claim to support 1080p 3d on the old HDMI standard.

As a future enhancement, I wonder if it would be possible and/or practical to design a 'jacket' that has a Hillcrest or equivalent sensor at the mid-point of all upper body joints (one or two on your spine, in-between your hips and neck, one as close to the center of your eyes as possible, one at each shoulder rotator cuff, mid upper arm, mid forearm, etc) and to use the combined data from those sensors to figure out exactly where all your body parts are with respect to each other using basic trig. I would imagine that some level of calibration would need to be done that involves taking physical measurements of all your limbs (for the purpose of determining where the sensors are WRT each other), and then mapping those values into the game's measurement system.brantlew wrote:Not sure if BlackShark is describing this correctly, but he brings up a good point.

You can only really measure the movements of rigid bones with that sort of orientation-only setup. With the spine, and especially the neck, you have to try and fix a lot of sensors in known fixed positions relative to vertibrae in order to account for the ability to shift the head sideways (i.e. translation without rotation).Mel wrote:As a future enhancement, I wonder if it would be possible and/or practical to design a 'jacket' that has a Hillcrest or equivalent sensor at the mid-point of all upper body joints (one or two on your spine, in-between your hips and neck, one as close to the center of your eyes as possible, one at each shoulder rotator cuff, mid upper arm, mid forearm, etc) and to use the combined data from those sensors to figure out exactly where all your body parts are with respect to each other using basic trig.

This setup would be for games where you're seated, but the concept could easily be extended to standing games by adding more sensors below the waist. Doing so would provide full body position determination WRT a fixed point (namely, your feet). The only movement that would require other means to detect would be jumping (no sensor angle would change during a jump)
This seems like such an obvious solution that it has to have been considered and discarded for some reason.
Thoughts?
That's precisely what I had in mind. Glad to see someone has done it. But yes, 4 large is a pretty big chunk of change. Maybe wide-spread Rift adoption will bring that price down.Fredz wrote:Answer : cost ($4000 for full body tracking).Mel wrote:This seems like such an obvious solution that it has to have been considered and discarded for some reason.

Would be less expensive for just the upper body, but still nowhere near a consumer budget.
You're the guy in the video? Great stuff. I was envisioning a wired version myself, or at least all sensors wired together with a central wireless 'master'. This could easily be stitched into a jacket of some kind.RoadKillGrill wrote:Like this? http://www.youtube.com/watch?v=MSTge5IDxF4
[Edit] I have been beaten to posting my own stuff X.x
The same sensors can detect jumping, as long as you assume a ground plane is where the feet are at rest. Positional tracking is good for a few seconds at a time.
Also if building the wired version the cost goes down by a good amount.

). Amnesia would make an incredible VR experience. I think the game would be very well suited for Rift. I believe it also has quite a lot of community-created content so it offers longevity too. Something you might want to consider.cybereality wrote:I picked up a few games on the sale. Namely:

Yes, this could be a problem. But I wonder if this would be really a big problem. And I think Palmer or Dycus mentioned 3rd person games as a viable option for VR.

You probably meant playing the game without head tracking, though. That could be fun. I wonder about motion sickness from swinging the camera around, though. I'm personally looking forward to testing that kind of thing out myself (at least for a couple of seconds, one single time
