Create World Space AR | Geospatial Creator Tutorial - ARCore in Unity

In this tutorial, you will learn how to create world space AR experiences using ARCore's Geo Spatial API and Unity. You will learn how to:
* Visualize 3D map tiles data in Unity using Cesium
*Create a scene that aligns with the real world
* Enable Google Cloud API etc.
By the end of this tutorial, you will be able to create your own world space AR experiences using Google's AR Core & Geo Spatial API & anchors

thank you so much for this tutorial !! easy to understand

[@thearvrguy]

Glad you liked it 😁

[@Pinkokinawa84]

Thank you so much for the tutorial :) This is great! Do you know how can we test where I put the anchor at home in Unity? For example, if I add an anchor to the effete tower in Paris, is there only way to test this is going to the actual location, or could we test it from home?

[@thearvrguy]

I don't think so, you have to be at the location to test this out but you can explore Ninantic LIGHTSHIP SDK or vuforia Area Target if you want results like this at your location with no VPS and it will be more stable .

@@thearvrguy Thank you ! I will check that!

[@user-ku9bo3hb5s]

well explained, thank you. Would you know what kind of problem I'm having? I can't manage to make the tiles work, I did every step but the 3d render of the world doesn't show up at all. I enabled the API (with arcore), made a key and everything. The sample scene also doesn't show up.

[@thearvrguy]

Make sure you've installed the correct versions... Check the documentation of you're using versions other than what I've used in the video and also make sure the cesium is setup correctly as shown in the video.

Nice tutorial. Did you face the issue of the gameobject drift in your project ? if yes , could you please let me know how did you solve it?

Thank you and regarding the drift, I think it will be there as it's relying on gps where vps is not available

Thank you so much! What if i wanna try to interact or touch the 3D object to make it spin for example, am i able to do it? Do you have a tutorial for that? thank you one again!

I don't have a tutorial for that.. But I guess you should be able to do it very straight foward...see if you can try the helper scripts that come with AR foundation samples to add interactivity to this

I'm setting Altitude type to Terrain and Altitude offset to 0 then setting gameobject exactly on the ground but it is instantiating at the same position(not Y axis) but the game object is not placed on the ground. Could you please help me with this senario.

[@thearvrguy]

Might be something to do with altitude value or the fact that VPS is not available at the location

[@user-nc6yi9ni2p]

Lovely tutorial, however i can't get a geospatial creator in my hierrachy. I use the 2022 LTS version. How do i go about this

[@thearvrguy]

Make sure you've followed each and every step mentioned in the tutorial and check whether you have enabled the geo spatial check mark in AR core settings

[@amitshrestha6833]

I'm a student and new to this, one quick question, can you add feature in the app to turn the AR on and off ? If so, how?

[@thearvrguy]

Yes, you can absolutely do that.... Check out AR foundation documentation/forums to know how to enable or disable AR

It's difficult to know what exactly is the problem without looking at the project....Try to follow each and every step precisely again...if it still occurs, then it might be because there are changes/updates happening which are causing this issue

its' working! I saw the game object, but the problem is the camera is black only. why is that?

I guess you're using URP, this issue comes with URP....When using URP, make sure to add the "AR Background Render Feature" to the render settings.

[@TheMelixor]

Where i should see the map after adding XR Geospatial origin? The video go forward very fast look like it is damaged

[@thearvrguy]

It's not damaged, I've fast-forwarded to not bore you guys , after adding the API key , you can select AR geo spatial creator origin. There you can see latitude & longitude, just enter the values of the place that you want to load, you're good to go By default, it might show you some random place but you can add your own coordinates as described above. Note : There might be some changes in the names/menus as there might be some updates to the SDK after I've recorded the video

[@TheMelixor]

@@thearvrguy thanks for the answer, but in my case, after followed you instructions the map is not loaded. Do you have any suggestion? I'm using uninty 2022.3.14
