Can someone view this pictures in their rift

I plan to use the rift for FPV flying, but I didn't have the patience to wait for my kit to arrive, so I started setting everything up first. But I need someone to try to view these stills from within the rift to see if they are properly compatible. Three things I want to know:

  • Do they converge properly with eyes focused to infinity? Especially for image #2, I modified the warp-params to tune down the warping because the camera already have a fish eye lens and also reduced the size a bit, but this may have made it unviewable.
  • Is the text overlay readable?
  • How is the image quality? Obviously it's not great, but do you think it's at least acceptable? If not, perhaps I need to look into different capture cards or camera..

    Here are the stills:

    Try this new one here: http://i.imgur.com/rlve0P4.jpg

    If everything turns out to be a-ok, I will post a proper tutorial soon on how to fly fpv with the rift, but in short, get an RCA capture card, a customizable OSD module like minimosd, and use this program: https://github.com/karai17/oculus-rift-webgl-stereo-cam In case you are wondering about the latency, it's decent but not perfect, maybe 0.2-0.3 seconds in total. But I think some of this is my camera's fault, because I have noticed some latency even when just outputting straight to the TV.

      Fantastic! Is the separation perfect or does it need a little fine tuning? I guess this would depend on the IPD anyway though.

      If the peripheral vision is not visible, do you think it would be better to reduce the image size a bit, so that one can just about see the black bars in the rift? I guess being able to view as much of the image as possible would be important in FPV.

      The separation looks fine for me, but I would play with the adjustments just to see what effect it has on the perception of relative size and distance.

      If that edge stuff is static, then no need to shift the OSD right. It is visible while looking forward, so stuff at the edges should probably blink or change color to get your attention.

      If you can, reducing the size would make it work better for many people who are using a much smaller FoV with their choice of Rift lenses and eye distance from those lenses. With a reduced size, you may be able to use more image overlap as well. But for ME, I want the larger size, so perhaps a size adjustment should be a user-selectable option.


      I agree that easily adjustable size and separation would be great, but unfortunately the software is not mine, so I cannot build on it. I've asked the creator to publish it on github or something but he hasn't responded. All I can do is modify the shader files manually. This is the program I used: http://www.spacefish.biz/blog/2013/04/ocolus-rift-fpv/
