Show reality data in Viewer component

[ovaisa]

I created web viewer app using as outlined in the Getting Started >> Online (Quick Start) >> 3. Get, build, and develop code

 https://www.itwinjs.org/learning/tutorials/develop-web-viewer/

Now added code in the app to view reality data (following the sample in frontend-sample-showcase>> Reality Data)

const availableModels: ContextRealityModelProps[] = await findAvailableUnattachedRealityModels(iModelConnection.contextId!, iModelConnection);

It doesn;t seem to get the info on reality model in the project. I am using the contextID and modelID of the imodel in iModelHub. It has both CAD and reality data. When I view the model in iModel Manager, I set both CAD and reality. The viewer app only displays CAD data (because the reality info is not returned).

@williamkbentley it appears applications registered via the dashboard lack the "reality-data-:read" scope?

const availableModels: ContextRealityModelProps[] = await findAvailableRealityModels(iModelConnection.contextId!);

is returning 18 models (tilesets)...

That suggests that all 18 of those reality models are associated with geometric models stored in your iModel. Can you confirm that? There will be a tilesetUrl property in the models' JsonProperties fields.

[ovaisa]

So I removed the second argument of

findAvailableUnattachedRealityModels(iModelConnection.contextId!); //, iModelConnection);

and it too is now returning 18 tilesets.

Is there a sample code that shows how to use queryRealityData(). I am just following the code in sample sets so would be helpful if you can point to sample that is using this public (rather than internal) function.

Thank you

[ovaisa]

The reality model was created by my client, I will have to check with them. I believe due to the size of the model as it was processed by ContextCapture in multiple (18?) tiles.

If this is true, do I have to attach all these models one by one to display style or is there a single url that points to the entire set.

[pmconne]

If a geometric model exists in the iModel with a tilesetUrl pointing to a reality model, all you have to do is add that model's Id to the view's model selector. If there are multiple such models and you want to see all of their reality models, add all of their Ids to the model selector.

We are working on making sure the samples use only public APIs. If you follow my link to queryRealityData you can see exactly how to call it by looking at the two functions above it. But if the reality models are already persisted in the iModel you should have no need to query the reality data service anyway.

[ovaisa]

queryRealityData() is returning tilesetURLs! Thank you Paul and Caleb for your assistance in resolving this matter.
