The NinevehGL Forum uses a new concept of "socialized forum" or as we like to say "Tweet Forum".

Here is the deal:
  1. No new registration is required. Just sign in with your Twitter account and authorize the NinevehGL Forum.
  2. Once you’re in, you'll be able to "Follow a Thread", that means every time that thread receive a new post or update you'll receive a mention on your twitter.
  3. Besides, you can enable "Auto Share", then every new post and/or thread you make will be tweeted on your timeline. (By default, auto-share is enabled only for your threads)

Forum Rules:

1. We understand human comunication can become "hot" sometimes. So some insults and bad words ARE allowed. Just don't push too much being an asshole all the time.

2. SPAMMERS are not allowed. There are penalties for this kind of user and they can be banned forever.

3. You can report other users, if you judge necessary. An user reported many times by many people can also be banned forever. However you can also receive penalties for report deliberately for no apparent reason.

If there is a similar thread title, make sure the other one doesn't already have the answer you're looking for.

I'm trying to change marker to my own image on Augmented Reality sample.

I created my custom image marker on Vuforia's Target Manager/Device Databases and downloaded it from there (I have .xml and .dat file). Then I put them to where NGLAR.xml file is, it didn't work. So I tried to put them any other directory on project directory. Nothing works.

This is the line of code where the sample stops, it gives EXC_BAD_ACCESS (code=1, address=0x0) .

dataSet->load([@"GALATA.xml" cStringUsingEncoding:NSASCIIStringEncoding], QCAR::DataSet::STORAGE_APPRESOURCE);

That means it can access it. But if I write a random name abc.xml for example. Which is it not in project directory. The sample compiles and opens. From this I understood that I'm missing something but I can't figure it out.

Is there something that I'm doing wrong? Can you explain it to me.

I met the same problem and still stuck there.

I tried my database in Vuforia examples and it works fine.

So didn't have a clue yet. Looks for help.

Hi @mkeremkeskin - I'm having exactly the same issue as you describe here. Did you ever find a resolution for this problem?

Changing the parameter for the XML filename to something random allows the code to run, however a message appears in the output stating that the file could not be found. I'm guessing that the issue is during the loading of the .dat file itself, perhaps newer versions of the .dat files are incompatible with the version of Vuforia in NinevehGL?

If you did find a solution, would you mind posting it here please?

Hi, Tom i found the solution I'm pasting it below. It was two months ago maybe somethings has changed i didn't know about if there is that its yours to find

The newly generated image targets from Vuforia website works on just Vuforia SDK 3. So I upgraded the version in ninevehgl AR example. I changed library and headers also the code need some changes. Some linker flags should be added to the project also that was the part struggles me.

This was the explanation for what I did. But right know I can't remember the code changes and the linker flags. I have dig them up from Vuforia forums.

NinevehGL is a 3D engine built right on top of OpenGL ES and it uses all the programmable pipeline power, making it easy for you to create great application with shaders.
