Hi,
check your standard-lib / libc-settings. You must use the same settings you
used when compiling osg.

Re: [osg-users] GraphicsWindowCocoa Sample
Hi Yu, here’s a snippet of an app using osg inside a classic Cocoa-app. The trick is to let osg create a view only and then add this view into your NSView-hierarchy. osg::ref_ptrosgViewer::GraphicsWindowCocoa::WindowData win_data = new osgViewer::GraphicsWindowCocoa::WindowData( osgViewer::GraphicsWindowCocoa::WindowData::CreateOnlyView | osgViewer::GraphicsWindowCocoa::WindowData::CheckForEvents ); // self is a NSWindow/NSView osg::ref_ptrosg::GraphicsContext::Traits traits = new osg::GraphicsContext::Traits(); traits-inheritedWindowData = win_data; traits-x = 0; traits-y = 0; traits-width = [self frame].size.width; traits-height = [self frame].size.height; traits-doubleBuffer = true; traits-vsync = true; traits-windowDecoration = false; traits-supportsResize = false; // the following steps are deep inside my own app and it’s to cumbersome to quote them here. // 1. create the graphics-context with the traits-object // 2. create a osg::Viewer or a osg::View and set the gc accordingly. // 3. realize the graphics-context // 4. after realizing the GraphicsContext you can get the created view via the win_data-object. openglView = win_data-getCreatedNSView(); [self addSubview: openglView]; [openglView setFrame: NSMakeRect(0, 0, [self frame].size.width, [self frame].size.height)]; Another approach is the usage of GraphicsWindowEmbedded, here you’ll create and control the OpenGL graphics-context by yourself.

There are some starter tutorials, but I still have some questions (without having touched the toolchain right now) 1. Depending on the device I guess I'm bound to OpenGL ES 1 and 2? You are bound to ES1 OR ES2. It depends on the context you create. And you’ll have to setup cmake accordingly. 2. What about external dependencies, are there all available resource to get my favourites like curl, tif, freetype going? It’s hard to find the dependencies, I have some precompiled libs for curl and freetype. The hard part is to compile them for both the devices and the simulator. 3. How are plugins handled? Is there some delay load mechanism, or do they have to be compiled statically into the application? iOS require static linking. 4. Last of all: How well does it work? Is the setup/building/deploy working smoothly? If you master the hurdle of setup and compilation of osg and its dependencies its working w/o problems. The linking times are relatively high because of the static linking requirements. One major annoyance is cmake’s inability to compile socalled universal libs. These libs contain code for the simulator and the devices (arm6, arm7, arm64). I can open source my build-scripts which creates 2 cmake-projects in different folders, compile osg and afterwards create universal libs. If there’s any interest I can setup a git repository. Here’s an example of a working ios-app, which may guide as a blueprint: https://github.com/Present3D/present3d-control (it contains also freetype + curl 3rdparty-libs) cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi,
try a more recent version from trunk or the 3.2-branch, a fix for this issue
was added last week. It seems that clang/llvm does some too optimistic
optimizations. I could fix the bug by adding a explicit destructor (this got
committed to trunk) or by reducing the optimization-setting for the serializer
(this got committed to the 3.2-branch as it does not break ABI-compatibility)
Note that the github-mirror is currently not in sync with the subversion

Hi,
I had exactly the same issue than Jan Klimke when trying to compile the
latest osg with Xcode 5, 64-bit dylib build (not frameworks) with libc++ as
standard library.
Could anyone successfully build a recent osg with Xcode 5?
The problem is that the linker can't find the destructor of GUIEventHandler
when building the serializers:
Undefined symbols for architecture x86_64:
osgGA::GUIEventHandler::~GUIEventHandler(), referenced from:
construction vtable for
osgGA::GUIEventHandler-in-osgGA::KeySwitchMatrixManipulator in
KeySwitchMatrixManipulator.cpp.o
I found following workarounds, but none of them is good:
1) Remove the file
src/osgWrappers/serializers/osgGA/KeySwitchMatrixManipulator.cpp
2) Define an empty virtual destructor in GUIEventHandler (eg. virtual
~GUIEventHandler() {}).
Looks like a linker issue. KeySwitchMatrixManipulator is used at other places
sucessfully, it's just in the serializers that the issue shows up.
Any hints welcome.
Thanks

Re: [osg-users] OpenSceneGraph and Mac OS X
Hi Ron,
there might be a bug in osg, but I don’t think so, as loading files and
displaying them is a core feature, and more people would have stumbled over it.
It works perfectly on my end BTW.
I am using currently OS X 10.9 and xcode 5 to build OpenSceneGraph. But I have
used everything since 10.4 and the various xcode-versions.
Is there a chance that you have an old/multiple installations of OpenSceneGraph
anywhere on your computer (in one of your Lirbary folders for example)? Or old
release-builds mixed with newer debug-builds?
To narrow your problem down I’d start with one of the official examples like
osgviewer. If the example can open an osg-file and display it then osg works as
expected, so the problem is with your app or because of conflicting
build-settings.
These are my CMake-settings for OpenSceneGraph:
OSG_COMPILE_FRAMEWORKS:BOOL=ON
OSG_COMPILE_FRAMEWORKS_INSTALL_NAME_DIR:STRING=@executable_path/../Frameworks
OSG_CXX_LANGUAGE_STANDARD:STRING=C++11
OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX:STRING=imageio
OSG_WINDOWING_SYSTEM:STRING=Cocoa
I do usually out-of-source-builds, setting the build-binarys-folder to
something different than the source-folder in cMake.
When using osg-frameworks and plugins from within my app, I make sure that I
use the same standard lib, copy the frameworks and plugins to the correct
locations of my bundle and set the following compile-flags for my app:
Inline Methods Hidden (GCC_INLINES_ARE_PRIVATE_EXTERN) to 0
Symbols Hidden by Default (GCC_SYMBOLS_PRIVATE_EXTERN) also to 0
To test osgviewer I select the target from the popup, hit Cmd and add an
argument to the run-schema, basically the full path to an osgt-file for
example. Then I hit run. If the console reports that it can’t find the plugin
I’ll check the osgPlugins-folder. (This may be necessary when compiling dylibs)
That’s what I did this morning:
1. git clone https://github.com/openscenegraph/osg.git
2. start cmake, chooses xcode, set the variables, use a different build-folder,
hit configure multiple times and then generate
3. open xcode-file in xcode hit „Cmd-B“, wait 15 minutes
4. Locate the osgviewer-target in the drop down, select it
5. Hit Cmd „ select the „Arguments“-tab, add a new argument and drop an
osgt-file into it (or paste the full-path to a osgt-file into it)
6. Hit „Cmd R“
7. Now I can see the osg-model fullscreen.
Note, that this works only for the debug-build. If you switch over to release
make sure, that you build the INSTALL-target, as this target sets up the
dependencies-paths of the frameworks and plugins. This is mandatory to bundle
the osg-frameworks + plugins with your app.

Stephan,
I think I've found the issue - it seems that the
AvailableReaderWriterIterator isn't being used safely.
In ReaderWriter::ReadResult Registry::read(const ReadFunctor readFunctor)
you'll find:
// first attempt to load the file from existing ReaderWriter's
AvailableReaderWriterIterator itr(_rwList, _pluginMutex);
for(;itr.valid();++itr)
{
ReaderWriter::ReadResult rr = readFunctor.doRead(*itr);
if (readFunctor.isValid(rr)) return rr;
else results.push_back(rr);
}
and later on…
// now look for a plug-in to load the file.
std::string libraryName =
createLibraryNameForFile(readFunctor._filename);
if (loadLibrary(libraryName)!=NOT_LOADED)
{
for(;itr.valid();++itr)
{
ReaderWriter::ReadResult rr = readFunctor.doRead(*itr);
if (readFunctor.isValid(rr)) return rr;
else results.push_back(rr);
}
}
The first loop runs through the iterator until itr.valid() returns false.
The second loop never runs because itr.valid() immediately returns false, or
because a compiler optimization assumed that it would return false.
I suspect that when loadLibrary is called, the library is inserted into
_rwList, which would cause itr.valid() to return true, but it appears that
the second call (and the loop it's in) were optimized away.
The following code
// now look for a plug-in to load the file.
std::string libraryName =
createLibraryNameForFile(readFunctor._filename);
if (loadLibrary(libraryName)!=NOT_LOADED)
{
AvailableReaderWriterIterator itr(_rwList, _pluginMutex);
for(;itr.valid();++itr)
{
ReaderWriter::ReadResult rr = readFunctor.doRead(*itr);
if (readFunctor.isValid(rr)) return rr;
else results.push_back(rr);
}
}
appears to fix the issue.
There's probably a way to tell the compiler that it can't optimize that call
away (careful placement of a volatile keyword?) but someone more familiar
with that aspect of C++ would have to do it.
This all begs the question: How does one submit a bug report for
openscenegraph?

Another approach is to setup a osgViewer::GraphicsWindowCocoa::WindowData

Currently if there is a clang compiler, the standard used is still c++98. This is currently hard coded and not configurable from cmake. Since dependent projects use the c++11 standard and libc++ as standard library implementation, there are linking issues if osg is not build with libc++ due to incompatibilities of std::string in libstdc++ and libc++ I had to adapt some plugins (added some casts to remove compiling errors) in oder to make osg compile. Do you think it is useful to switch the c++ versions in CMAKE at least for newer CLANG versions. The current Xcode provides the clang 5 as default compiler.

Re: [osg-users] OSG Multi-Touch input. TouchData [SEC=UNCLASSIFIED]
Hi Mitch, There is an implementation for WM_TOUCH in GraphicsWindowWin32, haven’t tested it personally. It should be easy to add support for TUIO-touch-events to the existing OscDevice, as TUIO is transported via OSC-messages. There’s also a recipe for intercepting TUIO-events via https://github.com/xarray/osgRecipes/wiki, haven’t worked with it. The multitouch-trackball-manipulator is not specific to the Apple trackpad, as it works with the TouchData of an osg-event and should be device-independent (I’ve tested it it on IOS and OS X). But as Christian already noted, the mt-manipulator is more a proof of concept than a stable working one. It’s hard to extend the existing manipulators, as they are all modeled with a single pointer device in mind. As you can see multitouch is still in its early stages :-) so any help is very appreciated! cheers, Stephan Am 11.09.2013 um 02:29 schrieb Doran, Mitchell (Student) mitchell.do...@dsto.defence.gov.au: UNCLASSIFIED Thanks for the reply, This example seems specific to the Apple Trackpad.

the rest-http-plugin needs the separate asio-lib (technically only the

the asio- and boost-headers, no libs needed. This was easier to setup,
especially on windows.
Point the ASIO_INCLUDE_DIR to the include-folder of asio, e.g.

Sorry, getting osg compiling running on ios is a bit rough. If you have a working set of libs and includes the experience is getting better :-) There's a helper script to compile all libs for debug/release and device/simulator and combine them to universal libs at https://github.com/stmh/osg/tree/iphone/PlatformSpecifics/iOS This script will create two xcode-project-files (simulator / device), compile all libs + plugins and bundle the libs. I think I submitted it to osg.submission, but it's not merged yet to osg-trunk. cheers, Stephan Am 29.11.12 13:05, schrieb Koduri Lakshmi: Hi, I added libOpenThreads.a file to BuildPhases-Link Binary With Libraries.

attached cmakelist.txt fixes the build for windows. There was an
additional missing lib.
Can you test it on your end?

I've just copied in the include of ws2_32.dll as is done in the osgcluster

Hi Gianluca, the message PixelBufferCocoa :: realizeImplementation not implemented yet should not lead to a crash. Without a stack-trace it's hard to tell why your app crashes.

Am 13.09.12 14:59, schrieb Matthias Thöny:
Hi Stephan,
thanks for your file and the information. I saw that the file contains all
values from 0...1 and I realized that with the current implementation this is
not working, because as far as I have seen, after the call
Code:
CGContextDrawImage(bitmap_context, rect, image_ref);
CGContextRelease(bitmap_context);
the byte array contains values like
128 128 128 255 (for 1 Pixel).
So in fact, may be there are in the end float values, but they are scaled to
1... 255 in the current implementation, this is also why you end up having
RGBA and unsigned byte. (probably there is aliasing in the resulting
OSG::Image).
I tried implementing this by myself and realized, that the whole function
should probably get another iteration, because at the moment the
bits_per_component are restricted to 8 and datatypes on grayscale bigger than
8 bits are not handled properly.
So it should be:
Code:
size_t bits_per_component = CGImageGetBitsPerComponent(image_ref);
//size_t bits_per_component = 8;
further at the position where you also fixed something the code should
contain a switch more, for the bits_per_component. Here is what I did (I did
not test the code with other pictures formats (gif, png etc..):
Code:
case 16:
{
BLOCKQUOTEimage_data = calloc(width * 2, height);
internal_format = GL_R;
pixel_format = GL_RED;
data_type = GL_UNSIGNED_SHORT;
bytes_per_row = width*2;
color_space = CGColorSpaceCreateDeviceGray();
bits_per_component = 16;
#if __BIG_ENDIAN__
bitmap_info = kCGImageAlphaNone | kCGBitmapByteOrder32Big; /* XRGB Big Endian
*/
#else
bitmap_info = kCGImageAlphaNone | kCGBitmapByteOrder32Little; /* XRGB Little
Endian */
#endif
bitmap_context =
CGBitmapContextCreate(image_data,width,height,bits_per_component,bytes_per_row,color_space,alpha_info);
break;
/BLOCKQUOTE}
case 32:
case 64:
{
BLOCKQUOTEimage_data = (float*)calloc(width * 4, height);
switch(bits_per_component)
{
BLOCKQUOTEcase 8:
{
BLOCKQUOTEinternal_format = GL_RGBA8;
pixel_format = GL_BGRA_EXT;
data_type = GL_UNSIGNED_INT_8_8_8_8_REV;
bytes_per_row = width*4;
color_space = CGColorSpaceCreateDeviceRGB();
#if __BIG_ENDIAN__
bitmap_info = kCGImageAlphaPremultipliedFirst | kCGBitmapByteOrder32Big; /*
XRGB Big Endian */
#else
bitmap_info = kCGImageAlphaPremultipliedFirst | kCGBitmapByteOrder32Little;
/* XRGB Little Endian */
#endif
break;
/BLOCKQUOTE}
case 32:
{
BLOCKQUOTEinternal_format = GL_R;
pixel_format = GL_RED;
data_type = GL_FLOAT;
bytes_per_row = width*4;
color_space = CGColorSpaceCreateDeviceGray();
#if __BIG_ENDIAN__
bitmap_info = kCGImageAlphaNone | kCGBitmapFloatComponents |
kCGBitmapByteOrder32Big; /* XRGB Big Endian */
#else
bitmap_info = kCGImageAlphaNone | kCGBitmapFloatComponents |
kCGBitmapByteOrder32Little; /* XRGB Little Endian */
#endif
bitmap_context = CGBitmapContextCreate(image_data, width, height,
bits_per_component, bytes_per_row, color_space, bitmap_info);
break;
/BLOCKQUOTE}
/BLOCKQUOTE}
break;
/BLOCKQUOTE}
I hope this helps others. I think for a submission one would have to refactor
the whole function. There are may be more cases to go especially for 64 bit
cases.
Thanks for the help!

This dev release won't contain all the submissions that have
accumulated over the last couple of months, if you one that is pending
please be patient. After taking things easy w.r.t open source dev
over the summer I'm now steadily going through submissions, it's quite
a backlog so it'll take me a few weeks to review them all. During
this period I plan to keep making dev releases rather than wait till
all submissions have been processed. If you feel a submission had
been missed out/overlooked please don't be shy in checking up on
progress on it, sometimes submissions I've actually responded to and
await a response that hasn't forth coming so it's worth checking up
just in case there is something else I need from the submission.
Thanks you help in test :-)

Re: [osg-users] change GraphicsWindowIOS
Hi Laith,
Can't you set the opaque-property of the gl-view' layer before realizing
the viewer? (Out of my head:)
osgViewer::GraphicsWindowIOS* win =
dynamic_castosgViewer::GraphicsWindowIOS*(your_context);
if (win) {
UIView* view = (UIView*)win-getView();
CALayer* layer = view.layer;
if (layer) layer.opaque = NO;
}
if this doesn't work I recommend adding a new flag to
osgViewer::GraphicsWindowIOS::WindowData and checking that flag from
inside GraphicsWindowIOS.
For the latter solution you'll have to recompile osg. And please submit
your changes to osg.submission or create a pull request for

Re: [osg-users] imagestream webcam
Hi,
create the image once and update it's data every frame and call dirty on
the image. It looks ike Convert_OpenCV_TO_OSG_IMAGE returns a newly
created image everytime it gets called.

Hi,
i have a problem with the streaming of the webcam as texture of a geode.. i
grap frames with opencv and than i create a osg::Image from every frame that
apply as a texture..Now how can i create a imagestream as it is done in the
osgMovie example? if i use the same dynamic_cast obviously it gives me back a
null object...than how can i make the texture update itself?
this is what i actually do (i'm now able to see just the first frame):
osg::Image* image = Convert_OpenCV_TO_OSG_IMAGE(imageCV);
//image-dirty();

Re: [osg-users] iPad3 Retina Display Support
Hi,
Your code looks correct to me. What is the ios deployment target for
the osg-project? It should be = 4.0
You can try to force the scale via
osg::ref_ptrosg::Referenced windata = new
osgViewer::GraphicsWindowIOS::WindowData(self.view,
osgViewer::GraphicsWindowIOS::WindowData::ALL_ORIENTATIONS, [[UIScreen
mainScreen] scale]);

Hi,
I'm building OpenSceneGraph from the head of the trunk on Mac OS 10.7 Lion
using CMake. The build works straight out of the box defaulting to the llvm
compilers.
I'm using OpenSceneGraph in a project built using gcc-mp-4.7, and so linking
to the libraries built in the above step from my project.
I'm experiencing a problem with primitive sets at runtime - Namely, a
primitive set I create causes a crash when it goes out of scope.
I've managed to boil my problem down to a very simple implementation:
Code:
int main(int argc, char *argv[])
{
osg::ref_ptrosg::PrimitiveSet p = new osg::DrawElementsUByte();
return 0;
}
When executed, with the OSG libraries built using llvm, and the program built
using gcc-mp-4.7, the following happens:
Code:
Tobys-MacBook-Pro:xxx tobiasduckworth$ ./3DRecon.app/Contents/MacOS/3DRecon
3DRecon(23649,0x7fff7612f960) malloc: *** error for object 0x10e163ec0:
pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6
However, if I build the program using the same compiler (llvm) as OSG, then
it runs fine.
My program uses OpenMP, so I need to use gcc to get this to compile,
otherwise I could move to llvm.
I also tried to build OSG using gcc, but this failed due to osgViewer using
Objective C.
Does anyone have any idea what might be going wrong here?
Should I be able to build OSG using llvm and my application using gcc?
Hoping someone can shed some light,
...
Thank you!
Cheers,
Tobias

Re: [osg-users] Mac OSX Lion Installation
Hi, Am 14.01.12 23:31, schrieb Erick Bazan: I'm really really new to OSG, I need to use it for my Virtual Environments class. I have some experience with OpenGL in Mac with Xcode. I've been searching all over the internet how to install OpenSceneGraph in Mac OSX Lion and use it with Xcode (4).

Anyone know how to install or compile OSG projects from scratch in Lion with Xcode, as I said, I'm new to the whole OSG. checkout/download the osg-source, download a recent cmake version, open it, select the osg-source-tree, select a build-directory, select the xcode-generator, make sure you set OSG_WINDOWING_SYSTEM to Cocoa CMAKE_INSTALL_PREFIX to your needs If you want embeddable frameworks, set OSG_COMPILE_FRAMEWORKS to 1 (otherwise you'll get dylibs) generate the xcode-project files, open them in xcode, compile the INSTALL-target, you should now find the frameworks/dylibs/plugins in your folder given to the CMAKE_INSTALL_PREFIX Probably the quicktime-plugin will not compile, there's a fix in osg-submission waiting for review.

Re: [osg-users] Exporting to SVG from OpenSceneGraph.
Hi, AFAIK, osg is not capable to export geometry to SVG. I used gl2ps[1] together with osg to export some geometry to SVG. Worked quite well. cheers, Stephan [1] http://geuz.org/gl2ps/ Am 14.12.11 15:26, schrieb Jesper D. Thomsen: Hi guys, I have a question regarding exporting to SVG from OpenSceneGraph. In our software product we use OpenSceneGraph for both a model view window and for a charting component. So far we have exported images from the charting component as bitmap images (by just rendering them to an offscreen pixelbuffer in the required resolution). We have however had some requests for exports from our charting component in a vector format compatible with the Microsoft Office software package (which pretty much means EMF files). Since EMF is very Microsoft-specific, I was thinking of using SVG as an intermediate format, and then using some converter package to create the EMF output. I saw SVG mentioned on the OSG mailing list earlier, but my question is whether there is any way to render to vector SVG from OpenSceneGraph (I kind of expect a hard no here)?

Hi Glenn, what version of cmake are you using?

You can adjust the settings also via the cmake gui. Am 29.06.11 09:13, schrieb Glenn McCord: I'm totally confused by the cmake command I'm supposed to be using.

All works fine on OS X and other windows boxes. On the intel-box the performance is really bad (about 3-4 fps) If i switch the stats on, the performce restores back to normal: 60fps. If I cycle through the various stat-modes performance is good, but as soon as the stats are disabled, the performance is back to 3-4fps.

Hi Robert,
I am a bit puzzled as the second problem I am having at the moment yields a
very different behavior when isolated out in a small repro.
This time I get an assertion.
Attached is a modified osggeometry.cpp file that triggers the assertion I'm
talking about. The assertion is raised when addSlave() is called.
This issue might be by design, though. Not sure.
Code:
osg::Camera *createRTTCamera(osgViewer::Viewer viewer)
{
osg::ref_ptrosg::Camera slaveCamera = new osg::Camera();
slaveCamera-setClearColor(osg::Vec4(0, 0, 0, 1)); // initialize alpha
to 1
slaveCamera-setClearMask(GL_COLOR_BUFFER_BIT);
osg::Matrixd projMatrix;
projMatrix.makeOrtho(0.0, (double)1, 0.0, (double)1, -1.0, 1.0);
slaveCamera-setProjectionMatrix(projMatrix);
slaveCamera-setReferenceFrame(osg::Transform::ABSOLUTE_RF);
osg::ref_ptrosg::Viewport viewport = new osg::Viewport(0, 0, 64, 64);
slaveCamera-setViewport(viewport.get());
osg::Matrixd viewMatrix;
slaveCamera-setViewMatrix(viewMatrix);
slaveCamera-setRenderOrder(osg::Camera::PRE_RENDER);
slaveCamera-setAllowEventFocus(false);
slaveCamera-setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT);
slaveCamera-setCullingMode(osg::CullSettings::NO_CULLING);
osg::ref_ptrosg::Camera masterCamera = viewer.getCamera();
slaveCamera-setGraphicsContext(masterCamera-getGraphicsContext());
return slaveCamera;
This will certainly lead to a crash, as slaveCamera gets deconstructed,
as the correpsonding ref_ptr goes out of scope. Try
return slaveCamera.release()
or change the signature of the function to
osg::ref_ptrosg::Camera createRTTCamera(osgViewer::Viewer viewer)
instead.
Can't comment much on the memory-leak issue, though.

Because Xcode 4.0.2 shows me other errors like curl.h: No such file or directory, although the libraries are setting right. Please advise. Any help is appreciated. As mentioned in the Readme, the current Cmake-configuration can't create valid build-configurations for the example-apps and I think this is the error you get. Just deselect BUILD_OSG_APPLICATIONS in cMake and rebuild. This should get you a set of static-libs and plugins. Then you can create a new xcode-project, reference the xcode headers and libs and start testing. The cMake-path for IOS is rough and error-prone, as there are some bugs in cMake and inabilities, (like creating a xcode-project usable for simulator AND device), this prevents a smooth user-experience. I am still maintaining the hand-crafted xcode-project on https://github.com/stmh/osg (use the iphone-branch), it can build libs for device and simulator has a simple working example, and you can include it into your own xcode-projects as sub-project. It doesn't build all plugins though, only obj, ive, osg and imageio. cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Perhaps this test coulde be separated out into several separate lines

Re: [osg-users] iOS: how to draw into a UIView object instead of app's window?
Hi Alessandro, I think you are entering unknown territory, nobody has tried what you are trying to do ;-) The current implementation creates an UIView and attaches it to the window, so perhaps you can get it to work via: osg::ref_ptrosg::Referenced windata = new osgViewer::GraphicsWindowIOS:: WindowData(my_window); // my_window holds the UIWindow set the x/y width/height of the GraphicsContext::Traits to the bounds of the view, you want to create. After creation of the GraphicsWindow the view is added to my_window, perhaps you can get it via [my_window subviews]. HTH, Stephan Am 20.04.11 13:00, schrieb Alessandro Terenzi: Hi, I'm trying to modify the osgviewer example for iOS in order to be able to draw into a specified UIView object rather than to the application's window. Basically I created a custom ViewController with a couple of views, one of which occupies a small area of the main window. Then, once the controller's views have been loaded, I setup OSG as shown in the osgviewer example, but instead of doing: osg::ref_ptrosg::Referenced windata = new osgViewer::GraphicsWindowIOS:: WindowData(window); I do this: osg::ref_ptrosg::Referenced windata = new osgViewer::GraphicsWindowIOS:: WindowData(my_OsgView); where my_OsgView is a UIView object. But this is not working, I get the osgviewer's view on screen but not where I expect: the viewer's view seems to have the same size of the UIView object (and this is OK) but it is displayed away from the UIView itself...I guess that the viewer's view is created has a 'child' of my UIView object but I expected that the viewer's view actually 'became' my UIView object. In other words it seems that another view is created instead of just using the one I created with Interface Builder. What is the correct way to draw in a generic UIView instead of the application's window? Thanks.

Hi Tang, some ideas: 1) you are creating your geometry on the X/Z-plane, for hud-displays you'll need the geometry on the X/Y-plane (see the osghud.cpp example). 2) your width and height doesn't make sense to me. the native resolution of an iphone 4 is 480x640 or 960x1280. Use osg::GraphicsContext::getWindowingSystemInterface()-getScreenResolution(0,w,h) instead. hth, stephan Am 25.02.11 10:16, schrieb Tang Yu: Hi, I am developing an AR program on iphone.

My questions: 1. After the program launched on Iphone, why was the viewer empty? I can not see any image in there. 2. Whether or not the codes about texture can make the image match the screen size exactly? Thank you for your help!

Re: [osg-users] compile error in iphone project, about field has incomplete type
Hi,
Does the SimpleExample compile+run?
check your build-settings, it looks like that the standard-libs and
-headers are not included. Compare them with the settings of the target
SimpleExample.

Hi, everyone,
i tried to add osg libraries to my iphone project. I compiled the libraries
from git's iphone example. But, after i added them to my project

Re: [osg-users] Empty line does not display
Hi Antoine, Am 22.02.11 17:19, schrieb Antoine Rennuit: Any idea of what happens? Could that be a bug? you are missing a geo-dirtyBound(). As osg computes the near- and far-plane from all the boundingboxes, every frame, your line gets clipped if you don't update the boundingbox of your geometry. cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] OSG 2.9.10 on iOS
Hi Dani + Robert, Am 21.02.11 11:04, schrieb Robert Osfield: The problems with not find the ive::Terrain::write read implementations is a peculiar one, I've just looked through the ive plugin and the Terrain implementation is there are looks OK as does the DataInputStream and DataOutputStream implementations. It seems Dani is using the handcrafted xcode-project from the git-repository, which had not included the Terrain.cpp for the ive-plugin. (I committed a fix for this to the git-repository and added a sample ive-file with texture) the xcode-project @ git doesn't get much love anymore, as all iphone related code is part of the official distribution. You have to use cmake to create an iphone-specific xcode-project-file. The handcrafted xcode project has some advantages, as you can build for simulator and device from within the same project (which doesn't currently work via cmake) and has a working example. Another advantage is, that you can embed the xcode-project into your own project, so all dependencies get build automatically. I'll maintain the git-repository in the future, but my time is limited, don't expect too much :-) back to the ive/texture-problem: I have no experience with the ive-plugin, so I converted some osg-models to ive and opened them via an osg-app running in the simulator. cow.ive (from cow.osg) shows no texture as cubmapping is appearently not supported for gles 1, i get a lot of open gl errors in the console. skydome.ive (from skydome.osg) works in the simulator. Perhaps your ive-files use opengl features or texture-formats which are not supported for gles 1/2, try increasing the notify-level to DEBUG_INFO, perhaps there's some more valuable information. cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Generating multitouch events
Hi Serge, Am 08.02.11 09:12, schrieb Serge Lages: Thanks for your replies, it confirms what I was thinking... The iOS way of sending events seems to be an exception, all the touch technologies I use (mostly MPX, Windows 7 and TUIO) send them separately, so I think it should be useful to add to EventQueue a way to track the events to put them altogether into the GUIEventAdapter, what do you think ? Sounds reasonable :) Perhaps it's a good idea to enhance/refactor the TouchData-class, so you can use it as a storage for all your touch-points and add a cloned copy via a GUIEventAdapter to the event-queue... just an idea. cheers, Stephan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
