[osg-users] osgText on Android
Dear All
I am trying to display a simple text on Android device using osgText. No
matter what I do I can't get to display the text out on the screen.
I am using GLES2 build.
Attached is the code. I have debugged and verified that the font is loaded.
The text would just not appear.
In the following function i create some 2D text and add that to the
scenegraph. text <- _overlayGeode <- _overlayCamera <- _rootNode.
namespace
{
static const char gTextVertexShader[] =
"varying vec4 VertexColor; \n"
"varying mediump vec2 TexCoord0; \n"
"uniform vec4 MaterialColor; \n"
"void main() \n"
"{ \n"
"gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex; \n"
"VertexColor = MaterialColor; \n"
"TexCoord0 = gl_MultiTexCoord0.xy; \n"
"} \n";
static const char gTextFragmentShader[] =
"varying vec4 VertexColor; \n"
"varying mediump vec2 TexCoord0; \n"
"uniform sampler2D GlyphTexture; \n"
"void main() { \n"
" gl_FragColor = texture2D(GlyphTexture,TexCoord0); \n"
"} \n";
} // end of unnamed namespace
void TerrainApp::initTextOverlays()
{
_overlayCamera = new osg::Camera;
_rootNode->addChild(_overlayCamera.get());
_overlayCamera->setReferenceFrame(osg::Transform::ABSOLUTE_RF);
_overlayCamera->setProjectionMatrixAsOrtho2D(
0, vfui::Global::instance()->getTrueWidth(),
0, vfui::Global::instance()->getTrueHeight()
);
_overlayCamera->setViewMatrix(osg::Matrix::identity());
_overlayCamera->setClearMask(GL_DEPTH_BUFFER_BIT);
_overlayCamera->getOrCreateStateSet()->setMode(GL_LIGHTING,osg::StateAttribute::OFF);
_overlayCamera->setCullingActive(false);
_overlayCamera->getOrCreateStateSet()->setAttribute(new
osg::Depth(osg::Depth::LESS, 0.0f, .0001f));
_overlayGeode = new osg::Geode;
_overlayCamera->addChild(_overlayGeode.get());
osg::Shader * vshader = new osg::Shader(osg::Shader::VERTEX,
gTextVertexShader );
osg::Shader * fshader = new osg::Shader(osg::Shader::FRAGMENT,
gTextFragmentShader );
osg::Program * prog = new osg::Program;
prog->addShader ( vshader );
prog->addShader ( fshader );
osg::ref_ptr textColor = new
osg::Uniform("MaterialColor",osg::Vec4(0,1,1,1));
osg::ref_ptr textTexture = new
osg::Uniform("GlyphTexture",0);
//set a sample text overlay.
osg::ref_ptr text =
TerrainApp::s_createText(osgText::String("Testing"), _datapath);
osg::StateSet *ss = text->getOrCreateStateSet();
ss->addUniform(textColor);
ss->addUniform(textTexture);
ss->setAttributeAndModes(prog, osg::StateAttribute::ON);
_overlayGeode->addDrawable(text.get());
}
osgText::Text* TerrainApp::s_createText(const osgText::String& str, const
std::string& datapath)
{
// text geometry
std::string textStr("Hello World"); // replace this with str.
osgText::Text* myText = new osgText::Text;
std::string font_filename = datapath + "/fonts/androidnation.ttf";
osgText::Font* font = osgText::readFontFile(font_filename);
myText->setFont(font);
myText->setCharacterSize(100.0f);
myText->setText(textStr);
myText->setPosition(osg::Vec3(500.0f, 500.0f, 0.0f));
return myText;
}
Any thing that I have done that is not correct? I am cracking my head. I
found a couple of examples / tutorials of osgText on Android using GLES2.
All of them dont seem to work. By right setting up text should be very
simple. Any help or advice will be greatly appreciated.

Shamim

Re: [osg-users] osgAndroid - Deploying and Debugging
Hi Rafa
I am sorry that I couldnt reply to this email earlier.
I was away and couldnt check my emails for a couple of weeks.
Yes, I could do that. I will reply to your email next week after going
through the changes again.
I started working on the Android example. I have made a few changes to the
working sample osgAndroidExampleGLES1 for my convenience. I have made the
sample to be in fullscreen and added some overlay nodes for user interfaces.
Strangely i found another issue. For all PUSH events when i get -1 for
getXmin as well as getYmin where as +1 for getXmax and getYmax. However
getX returns a value which which is correct coordinate. Hence all the
getXnormalized and getYnormalized values returned are wrong.
This is what i did:
Create a simple event handler and added this to using
osgViewer::Viewer::addEventHandler method.
class LayerManagerEventHandler : public osgGA::GUIEventHandler
{
public:
LayerManagerEventHandler(LayerManager& layer) :
osgGA::GUIEventHandler(), _layerManager(layer) {}
virtual ~LayerManagerEventHandler() {}
bool handle(const osgGA::GUIEventAdapter& ea, osgGA::GUIActionAdapter&
aa)
{
// *** here ea.getXmin, ea.getYmin, getXmax and getYmax return
-1,-1,1,1 respectively.
// however getX return 897 and getY return 324 which is correct.
}
LayerManager& _layerManager;
};
//
This causes all the manipulators to fail. Did anyone observe this behavior?
Am i doing something wrong?

Hi Just an update. I managed to make osgAndroidExampleGLES1 work based on the Android.mk settings for osgSimple and am able to load cessna.osg or any other osg models. However, i am still not able to make osgSimple work based on the predefined setting.

I have also managed to compile and run the osgAndroidExampleGLES1 on my mobile device. I can see the blue background for the example together with three buttons. However, now when i try to load a model (cessna.osg) it shows error: dlopen failed: library osgPlugins-3.4.0/osgdb_osg.so" not found. DynamicLibrary::failed loading "osgPlugins-3.4.0/osgdb_osg.so".

[osg-users] osgAndroid - Deploying and Debugging
Hi Recently we had a requirement to build OSG for Android and load a OpenFlight MetaFight file. This is what I did: - Checkout the 3.4.0 stable release of OSG - Installed Android NDK, SDK and Eclipse. - Used the toolchain to compile OSG for GLES1 - Downloaded OSGAndroid from GitHub - Imported to Eclipse - Build all the four projects So far there is no problem at all. Everything went smooth. However, when I am trying to deploy the osgsimple application using eclipse or trying to debug the application it throws an error saying: "Couldn't load gnustl_shared from loader dalvik.system.PathClassLoader". This is what I did: - Modified Android.mk to have the correct OSG_SDK path - Modified Android.mk to have the correct plugins (osgPlugins-3.4.0) Note: (a) No other changes made to any files downloaded from GitHub for osgAndroid. (b) The command used to configure cmake is <<< > set ANDROID_NDK=C:\Android\android-ndk-r10e > "c:\Program Files (x86)\CMake 2.8\bin\cmake.exe" .. -G"MinGW Makefiles" -DANDROID_NDK=C:/Android/android-ndk-r10e -DCMAKE_TOOLCHAIN_FILE=../PlatformSpecifics/Android/android.toolchain.cmake -DCMAKE_MAKE_PROGRAM="%ANDROID_NDK%\prebuilt\windows-x86_64\bin\make.exe" -DOPENGL_PROFILE="GLES1" -DDYNAMIC_OPENTHREADS=OFF -DDYNAMIC_OPENSCENEGRAPH=OFF -DANDROID_NATIVE_API_LEVEL=15 -DANDROID_ABI=armeabi -DCMAKE_INSTALL_PREFIX=C:/Android/OSG_ES1-3.4.0 > make -j 8 > make install I tried the above in Windows 10.

[osg-users] Need help with OSG Image.
Hi,
I am facing a problem with OSG Image and would like to seek some advice from
the community.
I have a model exported in IVE format. This model is just a quad with a
texture mapped onto it. I want to retrieve the original image from
osg::Image object and convert it to JPG/PNG or any other format. Seems
simple, but I am not sure what is causing the problem.
The image when loaded using osgviewer looks perfectly fine. But when I debug
and look at the contents of the osg::Image object I find that both the
InternalTextureFormat and the PixelFormat are invalid.
_internalTextureFormat33776int
_pixelFormat33776unsigned int
The pixel size is 4 bits per pixel. I tried using osg::writeImageFile with
extension as JPG, TGA and PNG. Nothing works. With extension as RGB the
image is saved but is incorrect. I think it is because of the fact that the
image is 4 bits per pixel.
So, what I did is to use ImageMagick to convert the image data buffer to a
common format (JPG, PNG or TGA). However I am unable to do the conversion
from the 4 bit per pixel to a 24 bit per pixel. Any help here would be
greatly appreciated.
My mechanism for conversion from a 4 BPP to a 24 BPP is as follows:
unsigned int total_size_in_bytes = image-getTotalSizeInBytes();
unsigned int row_size_in_bytes = image-getRowSizeInBytes();
unsigned int image_size_in_bytes = image-getImageSizeInBytes();
unsigned char* ptr = image-data();
unsigned int size = w*h;
unsigned char* writePtr = new unsigned char[size];
memset(writePtr, 0, size);
// i convert to byte array (not sure if this is the correct way to
do)
for(unsigned int i = 0; i size; i+=2)
{
writePtr[i] = (ptr[i/2] 4);
writePtr[i+1] = (ptr[i/2] 0x0F);
}
// now i have the byte array and i set to imagemagick
for (unsigned int y = 0; y h; y++)
{
for (unsigned int x = 0; x w; x++)
{
unsigned char c = writePtr[x+y*w];
Magick::PixelPacket* curMagickPix = 0;
curMagickPix = magickPixels + (y*w + x);
curMagickPix-red = c;
curMagickPix-green = c;
curMagickPix-blue = c;
}
}
delete [] writePtr;
I tried to attach the IVE file but the email bounced. So I am putting it up
for download. The URL is:
http://68.168.137.66/osguser/Ceiling_1LightingMap.ive

[osg-users] Static OSG compilation
Hi All, I am trying to compile OSG as a static library. I am using the latest updates (as of 29th June, 2010) from SVN. I used CMAKE to create the Visual Studio solution file. I think all the setups are fine. However, I am unable to compile one file which is GLStaticLibrary.cpp. It can't find any of the function declarations, like glActiveTexture and the rest. Did anyone else face this problem? If yes, how do I solve it?

Hi Will, Thank you very much for the suggestion. I will try this out ASAP and will let you know if it works. By the way, is NVidia aware of this problem? If they are then they should be fixing this problem.

For the 8800 GTX card, I have not been able to find a driver version to fix it. However, after hearing that it happened on another dual core machine, I was able to find others with the problem. It appears that it is an Nvidia bug. There are a couple of possible solutions. In the Nvidia control panel you may have a setting called Threaded Optimization. One of our computers has that setting available, but for some reason it doesn't appear on another. If you do have that setting, turning it off appears to fix the problem. If you don't have the setting, you can still turn it on or off in the registry. The path to the value is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\[your GUID here]\ if you have the value OGL_ThreadControl, set it to DWORD:0002. If you don't have it, you can add it. I did this on my dual core machine and that seemed to fix the problem. This setting apparently controls the driver threading, and there are a number of people that have reported the problem on dual core machines. This site: http://forums.nvidia.com/lofiversion/index.php?t9875.html has some information about the problem. I hope this works for you, let me know how it turns out.

For the 7900 card, all I had to do was install the vendor drivers that came with the card. I believe the vendor on that one was EVGA. I will be able to check the version tomorrow. I've had the problem on two 8800 GTX cards, one an Asus, the other an Evga. I have not been able to fix it on the Evga card yet. On the Asus card, there is an option in the Nvidia control panel under the 3d settings about threading that doesn't appear on the Evga machine. I have no idea why that is. That option fixed the problem on the Asus card. I will be able to check the exact name and setting of that option tomorrow. I will send another email tomorrow after I check the driver version and the extra setting to give you more information.
