I’ve been trying to install the ARToolKit so I can get at the NFT training tools. Every version of the toolkit I download says to use the installer executable but none of them seem to have one! Am I missing something? I’ve downloaded about three different versions and they all tell me to use an installer.exe that doesn’t seem to be there

1038

  1. Download artoolkit from this link:
    ARToolKit5.zip - Google Drive

  2. Extract it

3.You can find the required .exe files in the /bin directory.

How many individual markers are supported to be tracked at one time?

Thanks

Got the same error on UE4.19 and V1.11. Just sent the new output log on the email.

UPDATE: I deleted everything from iPhone and unreal, restarted the project from scratch. The very 1st time it run, the app gets stuck at “Loading…” screen. After rerunning the app, I get the white screen with the (Webcam init error). Tried both Launching the app and packaging it.

Thanks,

Hi guys,

Has anyone successfully managed to package for windows?

I’m always getting the ‘Webcam init error’ message.

Any help would be greatly appreciated

1045

Hi,

Did you try it with one of the full versions ? The demo can’t be packaged, it’s just running in the editor.

1046

Ah ok, yeah i’m using the demo version. I thought It was just me doing something wrong.

Then I will proceed to buy the commercial version, I just wanted to test that it meets the needs of our project first.

The only other things I would need to confirm first is whether…

  • Using 4 markers for 4 separate models is possible?

  • It’s possible to still display the models even when the markers aren’t visible anymore?

Thank you for the help

1047

  1. Yes you can track 4 markers at the same time
    Check out this example with multiple markers: https://www.youtube.com/watch?v=t6lOCmq65fc

  2. You can display objects on their last known position

1048

Ok Excellent, thank you very much.

Also, have you seen any examples of SLAM being used in cooperation with your marker tracking?

1049

Hi everything works really great, i love this plugin :slight_smile: I am struggling right now a bit with the display of a widget while a marker is detected. If i add a widget to the viewport in the levelBP when a marker is detected, then the widget displays perfectly. But i havent found the right spot in that BP to remove this widget once the marker is gone. I tried allready so many places, but the widget never goes away! anyone a suggestion?

1050

Hello,

In the Advanced sample project, open the level blueprint and in the tick function you will find all the GetMarker nodes. Each GetMarker node has a visibility pin. If the marker is tracked the visbility is true.

You can use this value with a branch node to hide / unhide the menu widget. (SetVisibility) In case you have more than one GetMarker nodes at the beginning of the tick function set a variable to false and only set it true if any of the GetMarker nodes visbility is true, then test against this variable.

1051

ahaaa thanks , thats a very good way. I tried to do it in a different (wrong :)) way.This will work for sure!

Yes. It works with 4.19 out of the box.

If you want to make it work on 4.18 you need to replace it with [FONT=courier new]Plugins\ARToolkitPlugin\Source\ThirdParty\ARToolkit\ARToolkit.Build.cs from the previous version.
