Re: [osg-users] OSG 2.9.10 on iOS
Hi Büsra, 2011/11/22 Büsra Gülten busragul...@hotmail.de: I really need some information about CMake variables. Could you please give me any advice? These CMake variables change the build of the OSG so that it does or doesn't use any of the traditional OpenGL fixed function pipeline, this also applies to shaders. You'll see places where these variables are use within the OSG source code, in particular in src/osg/*.cpp. Robert. ___ 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, I have a question about the CMake variables for iOS Porting. I know that they configure the use of OpenGL ES. But I would like to get more information about each variable. -D OSG_BUILD_PLATFORM_IPHONE_SIMULATOR:BOOL=ON \ -D BUILD_OSG_APPLICATIONS:BOOL=OFF \ -D OSG_BUILD_FRAMEWORKS:BOOL=OFF \ -D OSG_WINDOWING_SYSTEM:STRING=IOS \ -D CMAKE_OSX_ARCHITECTURES:STRING=i386 \ -D OSG_GL1_AVAILABLE:BOOL=OFF \ -D OSG_GL2_AVAILABLE:BOOL=OFF \ -D OSG_GLES1_AVAILABLE:BOOL=ON \ -D OSG_GL_DISPLAYLISTS_AVAILABLE:BOOL=OFF \ -D OSG_GL_FIXED_FUNCTION_AVAILABLE:BOOL=ON \ -D OSG_GL_LIBRARY_STATIC:BOOL=OFF \ -D OSG_GL_MATRICES_AVAILABLE:BOOL=ON \ -D OSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE:BOOL=ON \ -D OSG_GL_VERTEX_FUNCS_AVAILABLE:BOOL=OFF \ -D DYNAMIC_OPENSCENEGRAPH:BOOL=OFF \ -D DYNAMIC_OPENTHREADS:BOOL=OFF ..

Hi Büsra,
can you test the attached CMakeModules on your end? They disable the
QtKit-plugin and the Quicktime-plugin for Iphone(dev+sim). Place them in
the folder CMakeModules. Don't forget to reconfigure your project in cmake.

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

Re: [osg-users] OSG 2.9.10 on iOS
Hi Dani,
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.
The only anomaly I can find is that the ive/CMakeLists.txt file has a
Terrain.cpp listed, but no Terrain.h. Is there a chance that the
static linker requires the Terrain.h to be mentioned as well?
I have added the missing Terrain.h reference to ive/CMakeLists.txt and
checked this into svn/trunk. I have no clue whether it'll make any
difference at your end. Could you try it out? I've attached the
modified CMakeLists.txt.
Robert.

Hi,
yes, I did it. I finally commented the next lines as a temporal solution:

on DataOutputStream.cpp and
Code:
/*else if(nodeTypeID== IVETERRAIN){
node = new osgTerrain::Terrain();
((ive::Terrain*)(node.get()))-read(this);
}*/
on DataInputStream.cpp
It seems the functions read and write aren't implemented. Am I right?
My problem now is that I've loaded a couple .ive models and they appear at
the screen but didn't show their textures. Any of you know what can be the
problem?
Thank you!

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] OSG 2.9.10 on iOS
Hi,
yes, I did it. I finally commented the next lines as a temporal solution:
Code:
/*else if(dynamic_castconst osgTerrain::Terrain*(node)){
((ive::Terrain*)(node))-write(this);
}*/
on DataOutputStream.cpp and
Code:
/*else if(nodeTypeID== IVETERRAIN){
node = new osgTerrain::Terrain();
((ive::Terrain*)(node.get()))-read(this);
}*/
on DataInputStream.cpp
It seems the functions read and write aren't implemented. Am I right?
My problem now is that I've loaded a couple .ive models and they appear at the
screen but didn't show their textures. Any of you know what can be the problem?
Thank you!
Cheers,
Dani[/code]

Re: [osg-users] OSG 2.9.10 on iOS
I think I moved a step forward: I've built freetype lib for both armv6 and armv7, built OSG 2.9.11 (with warnings, see below), and osgviewerIPhoneExample without errors but when it starts I get the following error: *Setting up osg::Camera::FRAME_BUFFER* Program received signal: “EXC_BAD_ACCESS”. One thing I've noticed while building osgViewer is the following warning: src/osgViewer/GraphicsWindowIOS.mm:630: warning: incompatible Objective-C types assigning 'UIWindow*', expected 'GraphicsWindowIOSWindow*' The warning is related to a line in the GraphicsWindowIOS::realizeImplementation() method. Could this be related to the crash? Thanks.

Re: [osg-users] OSG 2.9.10 on iOS
Am I suppose to use another version of freetype? AFAIK no, it's a universal-lib (i386 + arm) and had worked in the past. FYI, I recently setup a FreeType Xcode project for iOS to support SDL_ttf. It is based on a blog entry written by Alfred Rossi. This might be helpful if you need to rebuild freetype. The source is currently on 2.4.4. My Mercurial repository is here: http://hg.assembla.com/freetype_ios_xcode With SDL, I'm using Xcode cross project dependencies so I don't need to carry around a separate prebuilt static library. I haven't spent any time investigating how to do that with CMake. But if anybody wants to see an example of the Xcode setup, I have a Mercurial repo that utilizes the subrepos feature (kind of similar to svn externals or Git submodules).

Re: [osg-users] OSG 2.9.10 on iOS
Hi, ios-support is still in its early stages (expecially the cmake-support). If you are building for the device, try to remove -mmacosx-version-min=10.x from your CMAKE_CXX_FLAGS inside of CMake. If that doesn't work, clear the CMAKE_OSX_DEPLOYMENT_TARGET-var and try rebuilding.

Re: [osg-users] OSG 2.9.10 on iOS
Thank you Stephan, I'll try your suggestions. By the way, is the current git repository ( https://github.com/stmh/osg/tree/iphone) supposed to work without any change? If so I'll try that. Cheers.

If you are building for the device, try to remove -mmacosx-version-min=10.x from your CMAKE_CXX_FLAGS inside of CMake. If that doesn't work, clear the CMAKE_OSX_DEPLOYMENT_TARGET-var and try rebuilding.
