AR Toolkit for Windows Phone 8.1

Question

Hello,

i wonder if there is any AR Toolkit for Windows Phone 8.1 Runtime Apps out there?

It only needs to track fiducial Markers. I've already tried to use GART, but it seems like it doesn't work on Windows Phone 8.1.

I've tried that example: Tutorial

xmlns:gart="clr-namespace:GART.Controls;assembly=GART.WP8"

After i insert that Line and try to use the Namespace

<Grid x:Name="LayoutRoot"> 
    <gart:ARDisplay Name="ardisplay" AttitudeRefreshRate="50" MovementThreshold="10">
 
    </gart:ARDisplay>
</Grid>

the gart:ARDisplay is underlined and the Warning says: "Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built."

Hope there are other options.

Appreciate every input.

Answer 1

The old Windows Phone version won't work as it's using a different runtime model. The Windows 8 version likely doesn't work as it's targeting the regular Windows 8 only.

You could however try to download the source code for the Windows 8 version and copy it into a Universal Project and build. The APIs available in Windows Phone 8.1 Runtime Apps should be the same as in Windows 8 so it's possible it would build without (big) issues.

You could use that version then. Their currently doesn't seem to be a binary distribution for Universal Apps.

Answer 2

It seems like most of the Source Code is written for Windows Phone 7. 

I am not 100 % sure if rewriting the whole code, so that it works on Windows Phone 8.1, is possible with my knowledge. 

Actually for me the only hope is that their is some kind of AR Toolkit for Windows Phone 8.1 on the market.

There are two editions of GART - one for Windows Phone (which targets Silverlight) and one for Windows 8. The Windows 8 version should be adaptable (as the Universal App Model is based on how it's done on Windows 8).

The alternative would be to build a Silverlight 8.1 App which should be able to use the Windows Phone GART without any further changes.

Oh Ok got it right now!

May i ask you, what are the downsides of Silverlight?
