Test Stereo3D without a Rift?

Hey VR Heads!

I had a question for the Oculus team: is there a way to enable some of the Oculus integration (SBS 3d, distortion) without a Rift connected?

With the version of UDK I was using, I would boot up what I was working on with RealD enabled. It was useful for investigating UI layouts and text size, and also just to see how things looked in SBS 3D. However, it seems that RealD is not included in the Oculus UDK.

I have been mucking around with the config files and the UnrealScript files (Oculus.uc, Stereo3D.uc) and haven't found a clear way to simulate the SBS 3D. Is this just a cut and dry detected/not detected situation going on in the untouchable source code?

It would be great to get a preview of how things will look while I wait for the dev kit to arrive!

    Huh, that's odd. Welp, I have no idea, then. I don't work on the UDK integration, so I'm not sure why they aren't working. Just gotta wait for your Rift, I guess.

    The funny part about all of this is that the EXE demonstration works without any Rift drivers, so there has to be a way to get UDK to run without the Rift.

    Edit: I stand corrected- thats a Unity integration

    You shouldn't be able to test the stereo without a Rift connected. The reason for this is because the stereo/warping algorithms pull parameters from the headset in order to work. So if you don't have a headset it defaults to the normal 2D functionality.

    Sorry for the confusion.

    Thanks for the clear and detailed answer, Andres! I figured it was something along those lines.

    thanks for the update.

    I'm curious on what parameters are used from the headset for stereo/warping. Just whether it's connected?

    Well the distortion constants are stored in the headset, which as used to feed into the warp shader. There are also things like IPD, and other eye related parameters that are used for the stereo.

    does that mean you'll be able to use devkits with games made for the commercial rift and it'll automatically know how to warp for the devkit?

    The idea was that storing parameters on the Rift would help with compatibility, since we would like games created with the developer kits to work on the consumer version.

    This is really good to know- knowing that the puzzles I make in UDK can be scaled. Thanks :mrgreen:
