  • Hello All, I am new to FME AR and need some some support on using it for viewing city infra data like water mains and sewer pipes on a city map of India.

I just started with the FME AR app available in Google Play and deployed it on my Samsung A73 5g mobile phone. This supports ARCore and the Depth API. I also granted permissions to use Camera, Location and Notifications.

 

I made use of the sample fmear file available at the FME site and tried opening that in the app. As the tutorial says, I should be able to see the sample AR content even without me having to be present at the true location of the assets in Canada.

 

At the time of opening, I pointed the phone to the floor after which it displayed a message Searching for planes. This was followed by a display of an array of points on the floor on my house with a message Pick a plane for model elevation with a green circle like icon spinning. After i touched the points displayed on the screen, i saw a push buton like icon and a small box with a label Hydrant.

 

Pls refer to attached image. Am i missing something?

 

Second, i made use of the FME Workbench and copied the table structue of the SHP datasets. I then digitised roads, water mains in EPSG:7785 projected coordinate system for Tamil Nadu in India with the linear units in meters. This perfectly overlays on the street map of India. I ensured that the columns and the values required for the transformers in workbench are available. I disabled the transformers that convert the Hydrant sketchup file and the transformer for hydrant. FME workspace generated the FME AR output roughly 1.5 MB in size.. Once again, this when opened in FME AR displays the select plane and pick a plane and does not display anything.

 

In my experience, you first use the button in the lower left with a cube on it to select your fmear file, then tap the plane to display the data on that plane. The white dots indicate the plane/surface is suitable.

Maybe try pinch and zoom out to see if it has appeared somewhere off screen? You should be able to pan around, spin/zoom the model.

I've attached a fmear file I was testing with when I tried something similar with local wastewater data which may help.

 

Thanks ctredinnick!

  1. Yes, i know that i need to use the cube icon to open the fme ar file. I had uploaded the file to my Google Drive and was able to access that from the FMEAR app using the cube button.
  2. Furthermore, it worked with the file provided by you. Thanks! I was able to visualise the red mains connecting to manhole like features. I was able to see that immediately without any hassles.
  3. It even works for the HouseDatset fme sample. It got loaded within a scond and i was able to zoom in and out.
  4. However, I dont get to see anything when i open the ARtutorialModel.fmear file.

All

I was able to crack this problem. The sample workbench ARTutorial.fmwt has a FME transformer. By default, it was set to readable by iOS devices only. I changed it to both iOS and Android devices and executed the workbench. This time i was able to open the AR view without issues! Please refer to the attached images.

Thanks ctredinnick and FME!

 

Finally, Does SAFE have any plans for enhancing this tool?
