Oh, P.S. If you leave ARItem.Altitude as 0 GART will treat the item as if it's always at the same altitude as the user. The item will appear to be on the horizon line.

Thanks for that! I'll try it.

Can you check if deploying and running SimpleAR from GART project gives you the same problem on your Lumia 800?
Also I remember having problems finding my items when compas required callibration.

It worked before with SimpleAR with the recommended GART, I'll try it with the current build in a few hours, I'll tell the results.

It's possible that Gyro is the issue.

If any of the services are unable to start (Camera, Motion, Location) GART will raise the ARDisplay.ServicesErrors event. In the handler of this event you are passed a ServiceErrorsEventArgs which contains an Errors collection. This collection contains information about which service(s) could not start and you can use it to build up a message for the user alerting them to which device(s) they're missing.

Hi, I'm using the newest update of GART and I have a problem using it on a Lumia 800.
As I described on the previous thread I was having troubles seeing my items on WorldView but It got fixed modifying a few lines.
My problem now is that I can see the items on a Lumia 900, but not in a Lumia 800, they just dissapear after a few instants appearing on the upper left corner. Could it be a problem with the Lumia 800 not having a gyroscope?

Since my items doesn't have an specific altitude, I'm setting it to them at the same altitude the GPS gets, but it doesn't seem to work.

Thanks in advance.

I'm sorry, I kind of answered myself in my question but didn't realize till you told me about altitude and starting checking that. As I said it changed to Location instead of GeoCoordinate, and I was still sending a GeoCoordinate.

Thanks!

Hi, a few questions / things to check: What device are you running your project on? Do you see items piled up in one place before they disappear? Can you log your current location to output console - is it steady or jumps? Do you create your list of items depending on current location? Do you set altitude on you items - if yes - can you try and set them to Double.NaN?

Hi, I'm using the newest build since I need to handle device's orientation. After I changed the .dll I noticed that now it uses Maps.Platform.Location instead of Device.Location.GeoCoordinate.
I just had to add the reference to Maps and now it builds, and I can see that my items can be added to the ARDisplay, but I cannot find them after a few seconds.
Am I missing something?

Thanks in advance.

Hi,

Is there any possibility to develop an application which uses marker based augmented reality?
is yes, how can that be implemented?

New Post: Adding Area(s)

mpullen — Thu, 14 Mar 2013 15:53:06 GMT

So I am looking at adding areas (bound by Geo-coordinates) so that when a user is identified as being "inside" an area, ARItems will show up, then when the user moves out of the area, those items will be removed. I want to be able to detect when user(s) enter / leave an area.

My idea is to have ARAreas defined, each with it's own set of ARItems, then in the ARDisplay loop through ARAreas and check if a user is within a specific coordinate range, or write a query that would return areas that are nearby.. For now I just want to statically add a few areas, would be pulling these values from a site eventually. If a user is within an ARArea then those area's ARItems would become available. Outside of the Area they wouldn't appear, but from the Map View the specific Area's and coordinate boundaries would appear as an overlay.

Also considering how to display ARItems based on Geo-coordinate, and direction.. (So you can see a ARItem only based on certain vectors / distance so the application can correctly operate on lines of sight, and the relative size of the ARItem.

Hi red87,

You should be able to grab latest gart and run it with your WP8 project. Have look at this issue tho: http://gart.codeplex.com/workitem/9942
As for stable release I can't give you any estimates. Also not sure about mvvm light toolkit, as I haven't use it before.

Hi piotrw,

I know it's not the right thing to do, but do you have an ETA? I have to start a new project with GART and I must use WP8, so I'd like to know when a stable release is planned :)

Anyway, if the current code compiles and runs with Wp8 so we can use it for testing purpose... I'm just fine with that :) how does GART integrate with toolkits with MVVM light?

Thanks!!! :)

Hi,

Add "X3D" to you project's Build / Conditional compilation symbols. This will assure, that GART is not using XNA.
Note, that GART is currently transitioning to support Win8 / WP8, so there may be some new issues, as the commit 71606 is not final/stable one

Hi,

I try to build your project (commit 71606) for Windows Phone 8, and I have many issues : The type or namespace name 'Microsoft.Xna.Framework.Graphics' cound not be found (are you missing an assembly reference ?)
Do you have a solution to have a assembly of your project for Windows Phone 8 ?

Thx !

Hi. It is 0 but seems like setting it to Double.NaN keeps them in horizon, thanks for that :)

Hi Keoz.

What is the altitude of your points set to?
If I remember correctly, setting it to Double.NaN should keep items on the horizont line.

Hi I placed some points to watch in world view however the locations can only be seen "below in the 3d world" so I can only see them if I place the phone in flat bed position like if I'm watching them from a high place in real world, this doesn't happen in the bing sample, can someone explain why this happens and how to fix it?

Thanks

Sorry, have not checked the thread for a while.

But I'm running it on windows phone 8 right now and even if it seems a bit bugged (as I didn't do any real change, if I remember correctly I converted the source to windows phone 8 and added the XNA dlls I needed manually) it works okay.

The problem is that it take a while for it to get to the right place (when I used with windows phone 7 it happen instantly, now I have to wait a couple of seconds) and sometimes they start to move by themself. But happy to hear some are working with a correct port.

GART has not been ported to wp8 yet but it is on our roadmap. We are almost done with win8 support then we will tackle wp8. For now you can do a wp7 project if that meets your needs (wp7 apps run on wp8). Sorry for the lack of support, were just trying to find the time amongst other commitments.

If you are interested in working on the port yourself, please contact me about joining as a contributor.
