Whoops. OK, I will test it in the morning again. Thanks for finding this!


Yes, I think is the best way, maybe if you find another bug or are
interested into contribute, then we can use this mechanism sending me
the patch directly.


Sure, why not. We are looking into doing some AR applications for 
Android, so we may use your library as a base to start from. If I have 
some modifications that will be beneficial for everyone, I will for sure 
send you a patch.

Catched! It was not in JNI, the problem was that in the Matrix constructor
I had the "a12" element repeated and setted in the "a13" position! The
example with the y-up orientation works as expected now. Changes are
checked in the repository.

I don't know gitorious, so hard to say. I can probably keep a clone of your

but for these tiny patches it is likely simpler to just send a patch

Thank you, there is indeed a bug there :S. I was able to reproduce it.  I
have also replicated it in native and it worked as expected, so something

Maybe we should establish a submission protocol. I think git and gitorious
has something to easily merge changes from different clones. Something
called merge request, but I'm pretty new in GIT and I don't have clear the

I have updated my code and the bug is still there.

You can get my modified example here:
https://dl.dropbox.com/u/6822332/org.openscenegraph.osgcamera.zip

The data files are here (just unpack the folder to /sdcard on your device,
it looks for files /sdcard/osg/*.ive):
https://dl.dropbox.com/u/6822332/osg.zip

Yes, that fixed the camera-related crash.


BTW, there is a syntax error in
org.openscenegraph.android/jni/JNIosgViewer.cpp:

@@ -138,7 +138,7 @@ JNIEXPORT void JNICALL
Java_org_openscenegraph_osg_viewer_Viewer_nativeSetUpView

The above makes it actually compile with the latest NDK from Google. You

Hello Rafael,

I have tried your osgAndroid library, it does indeed work for me
after fixing few details, such as incorrect project references in
Eclipse.


Nice to hear that worked for you, Could you post me the changes?, If the
changes are related to the Android.mk files, this is something you need
to change in order to build against OSG (maybe I need to add the note to
the wiki). If are related to the eclipse projects I will be happy to fix
them :).


I think that the name of the project referenced by example is wrong - it 
doesn't install the JNI libs with the Camera example unless you set the 
projects are referenced from the example.


I will check what other changes I had to make, but it wasn't much or it 
was specific to my setup.





I've been using MatrixTransform for AR applications and I don't remember
that kind of issues, but JNI stuff is tricky and maybe there is a bug
there. Sometimes if you don't keep correctly the reference count of OSG
objects between Java and C++ weird things happen.

Could you post the code or a simple example so I could check it on my
side? Anyway I'm going to test it in order to replicate your problem.


Sure, I can do that. The code is a simple mod of your example. I will 
send you a follow-up e-mail with the code and the other changes tomorrow 
when I am back at the office.

Re: [osg-users] [ANN] osgAndroid: Library for develop OSG applications in Android

[Jan Ciger]

Hello Rafael,

I have tried your osgAndroid library, it does indeed work for me after
fixing few details, such as incorrect project references in Eclipse.

However, I see a weird bug. I have modified the OSGOverlayCamera example to
load three .ive files - a cube, floor plane and a monkey mesh (Suzanne from
Blender). That works ok. However, as soon as I use MatrixTransforms to move
things around or to scale them, it goes wrong. E.g. setting scale factor to
0.1 makes my geometry reliably vanish (4x4 scaling matrix with 0.1 on
diagonal and 1 in the last element). Using scaling coefficient of 0.2
doesn't make it vanish, but doesn't scale it neither ?!

Then I wanted to swap the axes, because my geometry is y-up. So I have used
this matrix:

Matrix(1, 0, 0, 0,
   0, 0, 1, 0,
   0, -1, 0, 0,
   0, 0, 0, 1);

However, if I use this, add the geometry as children to this matrix and set
the matrix as scene data to the viewer, the geometry "explodes" (it is
stretched out into infinity) - as if division by zero was happening
somewhere or the matrix was singular (it obviously isn't).

Of course, the same geometry configuration with the same matrices is
working just fine if I add the matching C++ code to the native OSG example
from the OSG source. What is going on? Some sort of JNI type conversion
issue? I am not a JNI expert, so I have no clue there ...

For the record, I am testing this on an Acer Iconia A500 tablet, with the
Ice Cream Sandwich. It has Tegra 2 (without Neon, so using armeabi ABI)
chipset.

What is going on here?

Currently is only a library that you should download, compile and use it to
develop your own Applications (.apk). It is not accepted as a downloadable
SDK in the AVDManager :) (yet?, maybe in the future)

I think that "enable untrusted software sources" is needed to install any
application outside the Google Play store, i.e, any (.apk) application that
you want to install by yourself. If you build an application with
osgAndroid and it is accepted in the Google Play store then, AFAIK, then it
will be distributed through a trusted software source.

Maybe other Android developers with more experience in deploying
applications could give more info here.

Just out of curiosity, does this avoid the need to "enable untrusted
software sources" or whatever it is Android calls it?

Thank you Jan!, I have some AR examples that I want also release :) in the
next days. If you find any problem using it feel free to tell me.

I hope Robert does not mind that we use the osg-users list for these things.

Rafa.

Hi Rafa,

First of all congratulations, at the end you were able to opensource the
project!

You have now publisher rights in the new web, so feel free to add a
Community New in the openscenegraph.com. I think you might modify the page
http://www.openscenegraph.com/index.php/community/projects written by Paul
Martz to add the new project.

Cheers.

Excellent!

Thanks for not keeping this proprietary, it will certainly make it easier
to get going on Android.

[osg-users] [ANN] osgAndroid: Library for develop OSG applications in Android

[Rafa Gaitan]

Hi everybody,

I'm glad to announce osgAndroid (OpenSceneGraph for Android). It consists
in a set of Java/JNI wrappers of OpenSceneGraph and some helper classes to
easily develop OSG applications in Android.

The code repository is hosted in Gitorious:

https://gitorious.org/osgandroid

I still don't have a complete documentation, but some
quick start guidelines can be found here:

https://gitorious.org/osgandroid/pages/Home

The osgAndroid project has been initially funded by:

IRTIC(http://smagris3.uv.es/irtic/)
AI2(http://www.ai2.upv.es)
MirageTechnologies S.L.(http://www.mirage-tech.com).

But we all agreed in open the source code and try to make the life easier
to all osg developers that want to migrate applications to Android. The
project was initially developed with AR applications in mind, so you will
not find too many interaction tools there, and of course has some
limitations, but you can load and display a model with only a few lines of
code:

...
mView = new Viewer(this);
mView.init(false, 16, 8);
mView.setSceneData(ReadFile.readNodeFile("/sdcard/axes.ive"));
mView.setDefaultSettings();
setContentView(mView);
...

Some usage samples can also be found in the code, such as how to use the
Android device Camera with an OSG scene with transparent background or how
to mix osgAndroid and native code in an Android Activity, and much more
will be added.

I would also like to announce the project in the community news section of
the new site (openscenegraph.com), is it possible?

I really hope this will be useful to the community, and of course feel free
to contribute!

Cheers,
Rafa
