Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Looking for a VR based tutorial for hololens

Hi, I am interested to build an app, that uses the Hololens Spatial Mapping capability to generate VR. I would also like to attach a texture to the mesh, depicting certain scene of the app. Eg: A jungle scene.

  • This lesson goes through spatial mapping, converting the map to planes, and smoothing those planes.

  • I have done the hologram_230 already, but I am interested in apply a custom texture on different sides of wall of the surface mesh , obtained via Device Portal.

    I am expecting to be find a solution around take a panorama of the room that was scanned and being able to apply the texture or the wall, or similar concept. I want to create a realistic virtual environment, like the HoloTour app.

  • Yeah I don't know much about this subject but here is what I might do to approach this problem assuming you are using the same PlaySpaceManager being used in Academy lesson 230.

    SurfaceMeshesToPlanes.Instance.GetActivePlanes will return the various surface GameObject. You could then do something like the following to each of the returned GameObjects.

    GetComponent().material.SetTexture("_MainTex", theTexture);

    I am not sure if you need to swap out the Renderer for a SkinnedMeshRenderer and I am not really sure how you would go about doing this.

    Anyway sorry I could not be of more help. Good luck.

  • I would imaging if you are looking for a holotour type of experience, you would have more luck projecting your video on the inside of a very large sphere that you are in the middle of, and then headlock the sphere so it moves with you if you move within your physical space, that way you can't ever walk out of the best viewing area.

  • Do you know how I could get inside the sphere and still see the video? I have tried rendering videos *.ogv on 3d objects. For now, I tried to get inside the 3d objects but it doesn't work, I get a blank screen with a cursor. Do you have any idea how i can come up with this?
