Varjo XR-3 Mixed Reality Portals (with images)

Post by fheinz »

Hello everyone,

We have Prepar3D v5.2 (5.2.22.27615) and we want to use Portals to define an area to display Mixed Reality. Using our HTC Vive all works fine, but using Varjo, the situation changed. I will explain you the behavior with both HMD’s.

On virtual world we have an aircraft (Extra 300) and looks like this:

Image

On real world we have a mockup cockpit and a green screen. This is our test setup:

Image

First, I will show you the behavior using HTC Vive on Prepar3D. Here

Image

is possible to identify the Portals in gray. That portal are defining where to put the Mixed Reality. In

Image

you can look how mixed reality looks like in this case.

This is what we are attempting to do using Varjo XR-3.

In

Image

you can look the same portal’s setup using Vive HMD but through our XR-3. In

Image

you can look mixed reality with XR-3 using portals. The problem is that the mixed reality only works at the outside portals in the green screen, but actually we are searching for mixed reality inside portals, like HTC Vive response.

So, have you any idea how can we solve this?

Image

We changed Portals and Inverted Portals option in PassthroughMode on Augmented Reality configuration, but nothing changed.

We are searching the HTC Vive response, but using Varjo XR-3. Is it possible?

Thank's for all

Hi @fheinz,

I never tried to use chroma-keying and portals at the same time. I used portals only with the XR-1, I created the portals over my cockpit instruments area and that's where the Varjo video passthrough appeared. No greenscreen needed.

But if you want to use chroma-keying with the green screen from your screenshots I think that if you remove the portals you might get what you are looking for.
