How to make a Mixed Reality app for the Quest 3 - Part 2: Plane Detection

This is the second part of a short tutorial series, in which you will learn how to create Mixed Reality experiences on the Meta Quest 3. We will be building our app in the Unity game engine, using Unity's native 'XR Interactive Toolkit'.
In this video, we will look into the Quest's 'Space Setup', and the 'plane' data that is generated from this room scan. We will begin to explore how to visualize these planes. I will also show you how to set up Touch Controller input and tracking within your project.

excellent! so helpful, thanks.

[@samanthaah263]

Ready for part 3 🙌😍

[@LudicWorlds]

Working on it right now! :)

[@tubbypot]

can't wait for part 3

[@motoday3580]

Very cool!

[@haraldgundersen7303]

Great stuff. Very nice tutorial....

[@tomatogogo]

It's really helpful!

[@crimil610016]

Can't wait to see Part3. I really want to build a Disneyland in my room.

[@CoreGames2000]

Thanx for the tutorial
But when I open the app there are no any planes visible. I am using AR feathered plane prefab. And I have already setup my room space too.

[@rafaeltavares6162]

it would be great if you would do the same thing for unreal engine.

[@eBautistaBau]

Hi, thank you so much for create this tutorial, it is very useful, at the end of the video, I tried to use the github file, but it did not change the color of the things I mapped, I am using metaquest pro, do you think I can use these files as well or are only compatible with quest 3?

[@LudicWorlds]

Thanks! :) I do not own a Meta Quest Pro, so I can't confirm either way. However, certain types of 'furniture' that can be defined during the Quest's 'Space Setup', are not recognized by Unity's 'AR Foundation' (and hence will not be assigned a distinct color). There's some documentation here: docs.unity3d.com/Packages/com.unity.xr.meta-openxr@0.1/manual/plane-detection.html
You'll notice that some objects are simply classified as 'Other'. Could this be the reason you are not seeing different colored planes?

[@eBautistaBau]

@@LudicWorlds thank you for your feedback. I will keep trying.

[@christiantoffalori5355]

With Oculus Quest it is possible to achieve exact plane detection, automatically obtaining the angles of the physical object?

[@oXRaphaelXo]

ATM I'm not sure about accuracy of this, but you should be to get each detected plane gameobject's transform with position and rotation, and calculate from there.

[@313Blc]

I make step by step by tutorial, but if i run app after buil in unity (and before build i properly setup space setup with furniture ) app always on run popup "create new boundary" ... if i create new boundary, then ar feathered plane dont work (i dont see obstacles, or walls). Please help

[@313Blc]

Maybye i make bad space setup and new boundary. What making first ..space setup , or new boundary before run app?

[@danamuise4117]

I'm using XR Interaction Toolkit 2.4.3 and under Samples I expected to find AR Starter Assets. I no longer see this, did they move?

[@LudicWorlds]

It's likely that 'AR Starter Assets' is not available in that older version (2.4.3). Please update the 'XR Interaction Toolkit' to the latest version (2.5.2). Hopefully the 'AR Starter Assets' will then become available.

[@ardeni2561]

can i make it on quest pro device?

[@LudicWorlds]

Yes, it should work on the Quest Pro (although I'm unable to confirm this 100%, since I don't own a Quest Pro).

[@CyberMonk22]

where is the third part ?

[@CyberMonk22]

??

[@JuanLopezEspinosa-lk7nw]

When I turn on the app, the planes are all purple. I don't know why I have this problem, any solution?

[@only1avetrill]

are you fixed this?

[@cathychoi6959]

I just started learning Unity MR, your contents are amazing!

[@LudicWorlds]

Thank you very much for your kind words and donation! :) More MR content in the works.
