Hi all, I have been wanting to wrap an AR library for some time now, i have tried several of the SDKs out there without much success, recently someone posted a question about an SDK called EasyAR, I took a look at it and decided to give it a try, i have been working on it for a little over 2 weeks now, I have a lot of the classes wrapped up and tried re-creating their HelloAR example which only shows a 3D rendering of a cube.
You will need to create an account, sign in and create a new project with the same package name as the B4A project in order to receive a Key which needs to be used to Initialize the SDK, The examples can be downloaded once you sign up as well.
I have decided to create this post because I started thinking that it would probably be much easier and faster if a group of us could work together in finishing wrapping up this library, I am by no means a Java expert, i am taking an advanced class in college but again, i am far from being an expert.
What i have wrapped so far seems to work fine as far as I can tell, at least I don't see any crashes, the code compiles just fine and the app launches, however I have been breaking my head over the last couple of days as I can't see the camera preview, I have gone over the original HelloAR example's code and comparing it to the code I have in B4A which essentially is the same thing but wrapped up.
I compiled the original example in Android Studio and ran it on my Samsung Galaxy s10+ and the example works fine, the camera preview opens up and I can point the camera at one of the example images and when it is detected the colored cube gets rendered on the screen.
When I run the example in B4A with the wrapped library I have so far, I can hear the camera opening, in fact I have a lot of logs checking whether the camera is opened or if any other errors occurred but I always see that the camera is in fact opened, but for some reason the preview is not showing, I can see the screen going from gray to black, which is also the case in the original example with the exception that the camera preview is not started.
I guess what I wanted to ask is if anyone else in the forums with enough experience in wrapping up Java libraries is interested in taking a look, I can upload the code I have to gitHub so that maybe a few of us can work together and wrap the rest of the classes and release it to the forums when is ready, as I mentioned I am currently taking some college classes and don't really have much time, besides i'm already at a dead end in trying to figure out what's causing the cam preview issue, the only thing I see in one of the logs is a vertshader error, but it doesn't give me any hint as to what exactly the issue could be.
If anyone is interested and has the time, please let me know, I will send you a link to where the files can be downloaded and we can start merging our work together, if anyone else has a better idea of a better AR library we can also get started on that.
Regards,
Walter
