Re: [osg-users] OSG on iPhone (size?)
Hi All I've been spending the last few hours trying to save some extra KB off of my final exe size onIOS. In the end I got my final exe from nearly 10 MB down to 3.T MB, sweet ay I'm using OpenThreads, osg, osgUtil, osgGA, osgViewer, osgDB, depreciated osg pugin and imageio plugin. The trick has been firstly build the osg libs with Optimization set to Fastest-Smallest. Then I set my exe to build for ARM 7 only, this way you basically half the exe size. Bear in mind though that ARM 7 chips are only in 3GS and above One other tip is to only draw in the parts of the plugins you need e.g. I load Texture2D from files, but i don't tend to load Texture1D //USE_DOTOSGWRAPPER(Texture1D) USE_DOTOSGWRAPPER(Texture2D) Cheers Thomas -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=38662#38662 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi, Am 02.12.10 03:54, schrieb Chris 'Xenon' Hanson: I don't know if you can static link on iOS, or how you would go about doing it. For now static linking is the only way on IOS. So the lib sizes do not matter, as only needed code get linked into the app. And: most of the time I am only using OpenThreads, osg, osgDB, osgGA, osgUtil and osgViewer, you don't have to include all libs. One of my osg based iphone apps is about 20 MB which utilize some of the osg libs, and some of my own libs. 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 on iPhone (size?)
Hello Mike: I have not tried to build the iphone OS port but it appears in your cut and paste you have the Active configuration as Debug as seen with the link path .Debug-iphoneos/osg.build/osg-generated-files.hmap. What are the Active configuration targets available and if a Release target is available try to select that. There should be a drop down box labeled Active Build Configuration or an equivalent. There just appears to be some level of debug symbols still in your binary distribution.

Hi all, I've just checked out the OSG iOS (a.k.a. iPhone) port which several of you have been putting a lot of effort into. Congratulations on the achievements so far. Am I correct in thinking that the branch at https://github.com/stmh/osg/tree/iphone contains the most recent efforts? I have two particular issues which I've encountered so far. The first is that on iOS retina-display devices (currently iPhone 4 and iPod Touch 4G) the graphics are being rendered only half-size. I saw some discussion on this in earlier posts, but I can't see any fixes for this in the current repo. Does anyone have a fix coded up waiting for testing?

Re: [osg-users] OSG on IPhone
Hi Phil, Stephan
I have two particular issues which I've encountered so far. The first is
that on iOS retina-display devices (currently iPhone 4 and iPod Touch 4G)
the graphics are being rendered only half-size. I saw some discussion on
this in earlier posts, but I can't see any fixes for this in the current
repo. Does anyone have a fix coded up waiting for testing?
As Stephan rightly says I have a version with this working (attached) The
problem lies with the device screen size. Stephan seems to have to use
screen bounds (in points) where as for the retina displays we need to use
sceen size (in pixels). The problem lines are around line 77 of
IPhoneUtils.mm. Stephan if you could take a look at those changes and
possibly just add an if !3.2 statement or the like then I think we are ok,
but I think we need someone with both device types.
The second issue is that I'm not seeing animation on some animated OSG
models. Are there known issues with animation in the current port?
I've used basic animation exported from 3ds max into a .osg file
(haven't tried .ive) seems to work ok for me. I've also had software
skinning with osgAnimation working. Could the problem lie with your static
imports i.e. are you using .osg but not adding
USE_DOTOSGWRAPPER(AnimationPath)
Just a guess.
I'd like to help out where possible with this port, and I have a bunch of
devices I can test on.
* display-size bug for retina-displays
* FBO-rendering is not working correctly
Having someone with a few devices would be great as I'm just doing this as a
hobby and it's getting rather expensive :). As Stephan says we still have
the above two problems, I've almost fixed the FBO problem so I recon if you
have mutliple devices (especially an IPad) it would be great if you could
help put with the retina display problems.
I assume this is for osgART (you work for ARToolWorks right). I've been
using the open source ARToolkit at the moment (ported a version myself, is
there anything else available). I'm getting great performance and almost
have time to use render to texture and some post processing (although with
out rtt the fps is sooo smooth).
I'd be really keen to help out with any problems you have with the AR side
of things, e.g You'll find there is a bug in versions 2.9.8 when using
subload callbacks for npot textures. Things I'd be keen to learn about are
the different camera res' on different devices, I have an IPod 4th gen and
although you can request 640x480 and 1280x720 explicitly the other res' are
just called things like PHOTO which I have no idea if it ends up the same
res on a 3gs for example.
Anyhow I guess those are less OSG related and more AR, so on that side of
things feel free to email me direct.
Cheers
Tom

Re: [osg-users] OSG on IPhone
Hi Robert, thanks for your detailed replies. I am running an up-to-date Xcode 3.2.3 and iOS SDK 4.0.1 on an up-to-date snow leopard. As for the FreeType stuff, I think the case-sensitivty was a wrong interpretration of the compiler error on my hand. It seems there was a discrepancy between the search paths for includes and the paths actually existing in the repo. Something like 3rdParty/include vs. some Openframeworks folder (don't have the sandbox handy right now). Eventually I was able to build and run a universal binary for device (tried it on iPod Touch 2G with iOS 4), though I also experimented with the link line (towards IVE plugin).

Hi Stephan/All Sorry I've been gone so long, I've been dying of glandular fever for the last two months :( Nice one for getting this repository set up, I'm very keen to get IPhone version done and dusted. I can start looking into the CMake support, although I'll be starting from scratch as my cmake knowledge is limited to hitting the configure button in visual cmake :). I'll see if I can get an iphone xcode project out of cmake this weekend and report my results. From the above sounds like you got the proper quicktime imageio plugin to work? Thanks again Tom Hi all, I have set up an github repository for the iphone-port of osg, as there's some work to do, before it's ready for inclusion in osg-trunk. git makes it easy to keep the iphone specific modifications in a separate branch. It's my last version, I took the mentioned zip from Thomas Hogarth when it was available and did some bugfixing and updated osg to a more recent version. the iphone-port is now based on rev 11554. So feel free to send patches for the iphone port: you'll find the repository at http://github.com/stmh/OpenSceneGraph-port-to-IOS there are mainly two branches: master which reflects osgs subversion-version, and iphone which holds the modifications and project files for the iphone port. what's missing for primetime: * most important: Cmake build support, currently the iphone port uses a handcrafted xcode-project (again, argh!) * multitouch-support for osgGA and implementation in GraphicsWindowIphone * some fancy multitouch camera handlers :) what's working: * the core libs and the following plugins: osg, iomageio and some more testing and love. 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 on IPhone
a) you need to open source ( you may still link statically but any changes to OSG code should be open sourced ( and not your app code )) Just to clarify that. OSG is LGPL with the extention that you can link OSG statically into your app. This exception like the one in the wxWidgets license is aimed at embedded platforms where you don't have dynamic libraries. As Sergey said, changes to the OSG code should be submitted but statically linking OSG with your app doesn't affect your app. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=22250#22250 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Changhoon, sometime ago Robert wrote ( currently a mobile port of OpenSceneGraph is under development ) == In a websearch today came across a webpage today for the project Mobile OSG: http://www.imrc.kist.re.kr/wiki/Mobile_OSG I haven't heard about this before, anybody know anything more about it? Clearly there will have done the port, so will have solved an number of problems that current developers will be tackling in the port to the iPhone, so it's a shame not be able to leverage this. I can't see any notice of download of the source, perhaps it's just an internal project, or perhaps the source the code is hosted elsewhere or perhaps a prod needs to be done to make sure the changes are opened sourced as the OSGPL requires. == so a) you need to open source ( you may still link statically but any changes to OSG code should be open sourced ( and not your app code )) b) better yet you combine your efforts with current process to have mobile OSG.

The OpenSceneGraph has been ported to support for OpenGL ES 1.1 and OpenGL ES 2.0, and this can be found in svn/trunk and the 2.9.6 dev release. The OpenSceneGraph has also ported to the iPhone, but these code changes are still just provisional and not checked into svn/trunk yet. I'll be checking a few more of these changes in this week, and contacting the author of the changes to get the open ends tied up. The license for the iPhone port will be the same OSGPL (LGPL derivative) as for all other build targets - the same code base is almost entirely shared across GL targets so naturally uses the same license.

Hello Is there are anyone who know about license problem when modifying osg for iphone? Should I open source code or object file and overall or a part related to OSG? In the case of cocos2d, there is a special license for iPhone like the below. cocos2d for iPhone was originally licensed under the GNU LGPL v3 license. But since it is impossible to distribute 3rd party dynamic libraries for the iPhone, this license extends the GNU LGPL v3 license by allowing you: a) to use cocos2d for iPhone as a static library b) to include all or part of the cocos2d for iPhone sources inside your project This means that if you do a) and/or b) you are NOT forced to release your source code under the GNU LGPL v3 license.

Re: [osg-users] OSG on IPhone
Hi Robert Missed your previous messages, just spotted them on the forum. 1) #include TargetConditionals.h Yes, TargetConditionals.h does appear to be on all version of OSX, and my OSX project is still building so looks safe (that's after fixing Q3). http://www.opensource.apple.com/source/CarbonHeaders/CarbonHeaders-18.1/TargetConditionals.h 2) The OSG's existing XCode projects and deprecated, with CMake being the route we've been planning to the way to generate XCode projects. I haven't looked yet, but have been looking for an excuse to learn a bit more about CMake. I'll see what I can find out. 3) In src/osgDB/FileUtils.cpp you've added an #import Foundation/Foundation.h My bad, got left behind from some testing stuff, it's not actually required (the random one floating around line 230). Yes a compiler option is required to get XCode to treat the file as Objective C++, also the #define COMPILE_COCOA_VERSION is needed. 4) In include/osg/GL you've added a glReadBuffer implementation This was required to get the WindowCaptureCallback to compile and was just done as a quick fix. Although looking at it now, that line has #defines to stop it being used on GLES, so i'll take another look. 5) You have your own version ReaderWriterImageIO.cpp in: Another temp fix, I seem to think the proper version is depending on Carbon at the moment for some of the file Opening stuff. I don't think it would be too much hassle to get it working however. I was just a bit to keen to see some results :). I'll try have a peek this weekend and report my results. I'd also wanted to ask your thoughts on adding other inputs to osgGA. Mutli touch is going to be very common in the future so I feel it would be a useful feature, but what about things like accelerometers and GPS coords?

Hi Thomas, I dont know in which state is the 3ds max osg exporter. I use the osg exporter for blender, i maintain it and use it. Examples from osg-data comes from blender so it's a working path and the one i use. In futur there will be a collada that will support osgAnimation but not yet ready.

Re: [osg-users] OSG on IPhone
Hi Thomas, Congrats on getting the OSG up and running on the iPhone. I'm currently reviewing your changes, and will probably introduce the changes bit by bit, with parts requiring a little refactoring along the way - for these we'll need so to and fro between us to settle upon final code. First up I have a few questions: 1) #include TargetConditionals.h Does this header exist on all versions of OSX? Or is it just for iPhone? 2) The OSG's existing XCode projects and deprecated, with CMake being the route we've been planning to the way to generate XCode projects. Have you looked at trying to use CMake on the IPhone? Looking on the web it looks like others are already doing this for other open source projects so I believe it should be possible. 3) In src/osgDB/FileUtils.cpp you've added an #import Foundation/Foundation.h which isn't guarded at all so it'll break the build on other platforms. I presume this is a Objective C line, does this require gcc options under OSX to get it build cleanly? Later in the OSX specific code path there is an #include Foundation/Foundation.h so perhaps this would be OK for the Iphone as well if the ordering of the includes was changed. 4) In include/osg/GL you've added a glReadBuffer implementation. For the other GLES platforms I didn't need this as the examples/OSG lib code so I presume either I've missed something or that you've not go the OSG_GLES1_AVAILABLE macro defined correctly. Which parts of the OSG didn't build without this addtion to include/osg/GL? I'll keep doing my review and merge the parts that shouldn't cause any build issues.

The likely approach will be to initially start with a branch in our svn repository for the port to OpenGL ES, and then have me refactor svn/trunk to step by step pull in the changes till we have svn/trunk compatible with OpenGL ES 1.x and then later with openGL ES 2.x. The time frame is difficult to pinpoint right now as it depends on various different groups coordinating work as well just how quickly the technical challenges are surmounted. I would hope that we could see a OpenSceneGraph-2.12 release (the next stable release after the imminent OSG-2.10 release) with OpenGL ES 1.x support this autumn. Cheers, Robert.
