No eye offsets when rendering in stereo

February 26, 2019 - 7:35am #1

The left and right rendered images are identical in the DigitalEyeware sample. This appears to come down to the fact that getEyeDisplayAdjustmentMatrix returns an identity matrix for the left and right eyes rather than something that offsets either view.

I'm running on a Pixel 1 with Android 9.0. The sample appears to be using "VR ONE" as the selected viewer, which does appear to have eye separation properies.

The screenshot below should have parallax, particularly where the tip of the spout is:

Hello,

Taking a closer look I cannot see any parallax either. I've opened a ticket for core eng to investigate further.

Thanks,

Hello,

Can you test it out on an iOS device?

I don't see any parallax on any of the devices I run on (it's a small set though). Do you get differences between the right and left eye images on your Pixel 1? What does getEyeDisplayAdjustmentMatrix return for you?

Hello,

Do you have a comparative screen shot of a device that is running the same sample but displays the parallax you're looking for? I ask because I ran the 8.0.10 ARVR sample on a Pixel 1, with Cardboard viewer, and it looked fine to me.

Thanks,

Surely it is even more important that see-through eyeware is in stereo? Either way I get the same result using the sample ARVR-8-0-10:

Hello,

Why are you using the Digital Eyewear sample on a video see-through device? This sample is specific to optical see-through devices supported by Vuforia Engine - the Pixel 1 is not one of these devices.

It's more appropriate to use the AR/VR sample for stereo rendering on a handheld device.

Thanks,

Version 8.0.10 of the Android SDK, not Unity.

Hello,

Some questions:

  1. Which version of the Vuforia Engine SDK are you using?
  2. Which version of the Unity Editor?

Thanks,
