Re: [osg-users] Any OSGEdit like apps around?

[Raymond de Vries]

Hi Paul,

Maybe a stupid question but have you tried the osgedit? I see that 
people have put it on github too. Would be nice to update it and revive 
it? Essentially the OSG has not changed that much after all...


Cheers, good luck
Raymond

Any other ideas?

Re: [osg-users] Integrate Qt into OSG - not OSG into Qt osgQt

[Raymond de Vries]

Hi,

Wrt Qt: you might be interested in the upcoming rendering interface 
abstraction where no direct OpenGL calls are made anymore. Not sure if 
it helps, let us know!


Cheers, good luck,

Hi community,

I am struggling with the design of such a task. And I am a bit
familiar with Qt and other UI frameworks. The task is to embed the
whole Qt framework into OSG - including the event processing and let
OSG render ( through RTT ) the widgets content.

Any clue, hints what direction I should take?

Thanks a bunch as always!
Nick


Ufff, you are in for quite a battle, I am afraid. I have done this few
years ago when we were using Ogre and OSG for our virtual reality
simulators at work and we needed a proper UI framework to display user
interfaces inside the application.

You have basically two options:

a) Render the Qt widget/window into a texture/image, grab that and
display it as an OSG texture. Input from OSG can be fed into Qt's event
system by artificially creating and injecting events.

This works and it is how we have done it. Qt widgets can render
themselves into an image/texture directly, simply by calling their
render() method with proper arguments. We were able to display most Qt
widgets and render QML using OSG textures. Where things get very hairy
is the state management between OSG and Qt (Qt uses its own OpenGL
backend for rendering and assumes that it is in a certain state!) and
then input. When you aren't rendering Qt the usual way by showing
windows on screen but you only call render() and grab a texture, Qt will
not initialize some internal state relating to issues such as cursor,
keyboard focus, state of some widgets, etc.

The result is that you will have problems with cursor disappearing,
widgets not accepting keyboard input, keyboard shortcuts not working and
myriads of other problems like this. It can be solved to some degree by
digging into the Qt's source code, seeing which flags it is relying on
where and then manually calling the necessary functions to ensure that
they are set correctly. We have managed to get it to such shape that the
UIs were usable but if you need a very complex UI you will likely run
into problems. Also OSG's event system doesn't handle anywhere close to
the gamut of input events that Qt does, so a lot of things will have to
be emulated.

b) Implement a new Qt backend running on top of OSG.

Qt implements several of these backends, including a basic framebuffer
and OpenGL already, that is how they port Qt to different platforms,
such as phones or embedded hardware. This would be probably cleaner
approach if you really need the entire Qt to work but also a lot more
work than the above, because the API is fairly extensive, not super well
documented (this are really the dirty guts of Qt you aren't supposed to
normally see)  and may not have a completely straightforward mapping to OSG.

Good luck,

Jan

Re: [osg-users] [build] Building OSG 3.6.4 in Win64 TDM GNU.

[Raymond de Vries]

Hey Zachary,

You could do yourself a favor and check how many messages you sent about 
this subject. And therefore how much time you have been asking from the 
people in the (very friendly and patient) community of the OSG.


Let's speak for myself, answering one of your questions "Are there even 
any complementary OSG builders out there?". The answer is probably 
pretty simple when you place yourself in your audience: "A lot". I have 
one friendly advice for you: you are only asking questions here and seem 
to find someone who is doing a complex job with a lot of uncertainties 
from your side. On the other hand, you are not offering a lot yourself 
so what do you think is the balance? That is the reason why I personally 
delete your messages pretty quickly and I dare to think that others do 
the same.


I have a question for you: maybe you can consider to make a donation to 
some kind of organization in return?


Cheers, have a nice day,
Raymond

Nick is one of the most reasonably-priced guys I know of who are up to

use one of the non-TDM builds that are free.


You're asking someone to do probably at least a full day's fairly

who are qualified to do that aren't free, or cheap.

Hi Chris,

not open source.


Send me a PM for more details if you like.

It discusses using a plugin to convert an OSG scene to an OptiX scene,

Has anyone ever seen or used this code? Was it open source? It may be 
dated, but it would be a starting point for new work.


With AMD getting into the ray tracing game, it would be nice to have a

Hi Rodrigo,

Without having read your mail in detail I have a suggestion. Do you know 
artoolkit and the integration with osg? It sounds to me that you can 
learn from that project.


https://github.com/artoolkit/artoolkit5

Please keep us/me posted. Sounds like a nice project, have fun!

Hi,

I'm working on a project that will render a scene using openscenegraph, and the 
user will have the option to work with this scene in AR. The integration of 
ArKit in the application is almost complete, except in the conversion of 
ArKit's view matrix to the coordinate system used by OSG.

I uploaded the render of the OSG axis helper and the ArKit axis helper. As you 
can see, the y in OSG is x in ArKit, the x in OSG is z in ArKit and the z in 
OSG is y in ArKit. With that, I thought that if I switched the axes directly 
into the view matrix it would be correct. What I have tried can be seen in the 
two attachments with the code fragment that converts the ArKit view matrix into 
an OSG view matrix (ar_conv_vector_change and ar_conv_values_change).
None of them worked completely except that one of them was correct in the 
rotations and translations of the camera, but the position and initial rotation 
of the scene was completely wrong (The wall should be in the same position and 
point of view as before at the time that the AR mode is started, but was 
positioned as shown in the switched_values_view image).

In the end, the camera view matrix is:
m_camera_matrix = m_camera_view * ar_view_matrix;

I apologize for the long text, and I ask the support of the people of this 
forum, and if there is, who has already gone through this situation (with ArKit 
or other APIs)

Thank you!

Cheers,
Rodrigo

Re: [osg-users] Why is osgText::Text very slow when its text is changed?

[Raymond de Vries]

Hi Igor,

I would suggest to use the latest version of the OSG since the text code 
has been changed a lot. Not sure if it resolves your issue but worth a try.


Cheers,
Raymond

Hi.
I have about 4000 osg::Text drawables in the scene. If i'm changing their text

Hi All,

I have created a branch off OSG master for merging ANGLE/UWP support
that has been provided my members of the OSG community.  The branch
is:

If you want to see what changes were required the commit of the PR is:

https://github.com/openscenegraph/OpenSceneGraph/commit/a60cd972f62818d63d2198eec7dcf10fe7909d18

I am not a Windows user myself so can't test out personally, it would
be useful interested Windows users could try out the branch and if
everything works well we can merge it with OSG master.  Let us know
how you get on in this thread.

Cheers,

Re: [osg-users] load a osg model with rigged animation (exported by 3dsmax)

[Raymond de Vries]

Hi,

Not knowing the details of your model and how it is setup, it is 
hard/impossible to make other suggestions. I do know that the fbx format 
does support skinned models and that the osg fbx plugin can load and 
render them properly. Fbx supports a lot of combinations so I suggest to 
look into details of the code and not only do quick tests with some 
standard examples.


For specific solutions/in-depth help about specific models, it is best 
to contact me directly.


Cheers,
Raymond

Re: [osg-users] load a osg model with rigged animation (exported by 3dsmax)

[Raymond de Vries]

Hi Andrea,

I second Alberto's suggestion to use fbx when working with 3dsmax. 
Latest OSG versions are finding the latest FBX SDK versions correctly 
and the fbx plugin is built properly. At least, I can confirm this for 
Visual Studio on Windows.


You did not write details about your code and therefore we can give you 
high level tips and tricks. Did you start with the example 
osganimationhardware?


Cheers,
Raymond



On 24/11/2017 11:10, Alberto Luaces wrote:

Hi Andrea,

OSG is capable of that, but here the export plugin is likely to be
blamed, since as you describe it is exporting the armature as a regular
object.  You can inspect the osgt file with any text editor to check
that.

Other users have reported to work with the FBX format.

You could also take one more step, 3DSMax→Blender→osgexport and see if
it fits your usage.

With any major set of changes being merged there is always the chance
of build errors on platform combinations that we haven't tested yet,
so if you see an issue let us know and we'll try and resolve it as
soon as we can.

There is also chances of build breaks in end user applications as
there are a few API changes to osgAnimation.  My hope that most users
won't find issues and it should be just a case of rebuilding your

My plan is to tag the 3.5.8 developer release early next week, so
getting some testing of master across a range of platforms will help

Thanks for you help with testing, and thanks to Julien for his efforts

Re: [osg-users] People currently using the ffmpeg/libavcodec plugin?

[Raymond De Vries]

Hi Chris,

I remember a few discussions about this subject. Please search the archives.

One of them is https://bitbucket.org/digitalis/osg-ffmpeg-plugin if I remember 
correctly this one can do 4k.. plz keep us updated.

Cheers!
Raymond

Hi Julien,

Could you let me/us know to which mail you attached your modified 
nathan? I can't find it. Can you let me/us know or send it directly?


Cheers
Raymond

Hi
I'm a bit concerned about the nathan.osg compatibility with RigTransHW..
I attached in my last a modified version of nathan (without shared ss) that 
should work (and so would replace the current one in osgdata).

I would be glad if Raymond (or other) could validate this model (ideally under 
win32) with the following tests
softwaretest : osganimationviewer nathan2.osg
HWtest:  osganimationhardware --number 1 nathan2.osg
(Don't forget I changed the maxnumbones type from int to uint in skinning.vert )
Once these tests validated elsewhere than my computer, It will confort me in 
the validity of the branch so i can make PRs to master (and to osgdata).

Thanks for the testing.


Julian, if you feel osganimation is now ready could you generate a PR for the 
branch and I'll go ahead and merge it.


Cheers,

Hi Robert,

I have not seen any issues in our own use of the osgAnimation. We tested 
in a few different setups and all seems ok.


The only thing is that the example did not work for me with Visual 
Studio 2015, while it does work for Julien.

waiting for it, you can change  new myRigTranformHardware with new 
osgAniamtion::RigTranformHardware.
This example is an attempt of program sharing among rigs but it can't be done 
without knowing the common maximum MAX_MATRIX.
MAX_MATRIX could be removed easily from the shader logic...(by simply 
accumumulate weight until sum reachs 1) perhaps I will do that one day..if it's 
no too controversal...

I used nathan from git, btw. I guess that is the correct one (and nathan

Thanks for reposting, changes now merged and master and osganimation

you posted it from an address that isn't subscribed to osg-submissions

I double checked and the address was already subscribed (I also get

Hi,

FWIW, I tried to build the osganimation branch last week or so with 
Visual Studio 2015 and it did not build. I did not have time to look 
into the issues but plan to do so asap.


Fyi, I will test with fbx models that I have used successfully with 
previous versions of the OSG.

Hi Robert
I just did a commit of my experimental useless bone removal method.
So long so far I didn't have any issue with my Blender test models (which represent a 
"outnumbered sample" of 2 models...one with ik the other with morphtarget)
However, I didn't have any feedback from the community or original maintainer 
so I can't certificate it 100% bugfree.

 From my point of view, I achieve to do whadIwannado with it (MDI crowd) so I'm 
quite satisfied with the current version and would vote for merging, but it's 
just one perspective among other ...

Cheers

Hi Julien,


What is the status of the osganimation branch?  How close do you feel we are to 
merging it with master?


I haven't done recent testing on osganimation so don't have any personal 
observations to chip in, but plan to start looking it with a view to merging 
with master.


I will also tag a dev release early next week so could possibly merge 
osganimation for that.


Let me know what the status is so I can start planning my review time.



Cheers,

Robert.

Hi All,

I have just tagged the 3.5.7 developer release to wrap up various 
community and my own fixes/refinements since May.


https://github.com/openscenegraph/OpenSceneGraph/tree/OpenSceneGraph-3.5.7

I still have a couple of branches (text_improvements and osganimation) 
that are still in development that haven't been merged with master 
yet, but now the 3.5.7 is out I'll merge these soon and these will 
then roll into 3.5.8.  I'll ping the community for testing prior to 
merging these branches.

Re: [osg-users] Adapting a height field with a triangle/polygon?

[Raymond de Vries]

Hi everyone,

Thanks a lot for your suggestions. Based on your extra remarks, we will 
make up our minds and go on.


Cheers,
Raymond

Hi Raymond,

There a number of ways of mixing polygonal data with height fields, 
the best way will depend upon the requirements/constraints of your 
application.


If you need exactly intersections then converting the height fields 
into a polygon mesh and then inserting the vertices and edges from the 
mesh you want to add will be required. This will be slow so something 
you'll likely want to do as a pre-processing stage.  The osgTDS code 
that Don wrote many years back uses this approach.  I'm afraid I don't 
have an insights into osgTDS or where to get it these days.


If you don't need exact match then you could possible modify the 
height fields values to match the polygonal mesh, you could do this on 
the CPU as a pre-processing step, or render the polygonal mesh to a 
depth texture and then use a vertex shader to read from two 
depth/height field textures to render a single heightfield.


Another approach would be to use a constructive solid modelling 
approach, at least I have hunch you could do this somehow but would 
need to think it through fully first.


Given more time I'm sure I could come up with half a dozen more 
approaches that may or may not work :-)


Robert.

Hi.

TL;DR Sample OpenSceneGraph application in Web:

Give it a try!

-- Official --

I've finished my work on the OpenSceneGraph cross-platform guide:
https://github.com/OGStudio/openscenegraph-cross-platform-guide

It contains step-by-step instructions with screenshots how to build
and run sample OpenSceneGraph application under the following
platforms:
* Linux
* macOS
* Windows
* Android
* iOS
* Web

It also contains YouTube and downloadable (MP4) videos depicting every step.

I hope this guide fills the gap of good cross-platform documentation
for OpenSceneGraph.
I plan to maintain it and update whenever something changes in the
build process. Drop me a line if anything becomes outdated and/or I
have missed it.

-- Personal --

Last year once I got the first taste of my own game editor results (
opengamestudio.org ), I realized supporting only desktop in 2017 is a
no-go. So I started to research Android support.
Since OpenSceneGraph Android samples are of pre-AndroidStudio era and
I was a newbie in Android native development, I spent literally
several months trying to get OpenSceneGraph render under Android.
Then came iOS and Web, which were just a piece of cake, compared to Android.
I realized that there may be many people who waste as many months just
to get OpenSceneGraph to mobile and web. That's why I decided to share
the knowledge in the form of detailed tutorials with screenshots and
videos of the whole process.

I hope this saves you precious time!

Re: [osg-users] Update to Depth Patitioner

[Raymond de Vries]

Hi Ravi,

It is hard not to be interested, after your enthousiast mail. So yes!

Cheers,
Raymond

Hi all,

A looong time ago I had created the DepthPartitionNode, which split up an OSG 
scene into multiple depth partitions and rendered them with multiple cameras. 
This turned into the original osgdepthpartition example. My implementation 
created nested cameras, which worked fine at the time, but posed some problems 
with shadows. The solution to this was to use slave cameras, and eventually my 
DepthPartitionNode was removed from OSG in favor of the dual slave camera 
approach that is currently in osgViewer::View.

Recently I've gotten back into OSG-related development, and my first task has 
been to rewrite the DepthPartitionNode. I've created a new DepthPartitioner 
class which dynamically creates and manages slave cameras for a given 
osgViewer::View.  A few features of the new DepthPartitioner class:


*Creates its own "main" slave camera, and attaches a slave update callback that 
dynamically creates additional slaves to render depth partitions. Important to note that 
it doesn't mess with any callbacks that may be installed on the View's master camera.

*Obeys the relevant settings of the View's master camera. e.g. near/far ratio, 
graphics context, viewport, view/projection matrices (except depth of course).

*Disables its unused slave cameras instead of destroying them, since the 
osg::Camera is lightweight.

*Cleans up after itself when you no longer need to depth-partition the 
osgViewer::View.

*Specify a minimum zNear that will never be violated. This is useful for VR 
applications where you really don't want anything drawn closer than a few cm 
from the eye.

* Customize how slave cameras are created. By default one camera is created per 
depth partition, but this can be overridden to create stereo cameras per 
partition for rendering unlimited depth precision within VR. I've done this, 
and it's VERY cool to sit on a satellite with the Vive and watch other 
satellites in your constellation move around you while you orbit the Earth.


I was wondering, is there interest in this for the general OSG community? 
Currently it resides as a part of my own Open Source OSG-based API, but I would 
be happy to contribute it as standalone code to OSG.

Thanks!
Ravi

Re: [osg-users] OSG with Qt on Android fails to render anything

[Raymond de Vries]

Hi Andrea,

One question/test: have you been able to run osgviewerQt on Windows for 
instance? Usually, I need to patch src/osgQt/GraphicsWindowQt.cpp in 2 
locations in order to prevent illegal values for scaled_width and/or 
scaled_height:


void GLWidget::resizeEvent( QResizeEvent* event )
{
const QSize& size = event->size();

int scaled_width = static_cast(size.width()*_devicePixelRatio);
int scaled_height = static_cast(size.height()*_devicePixelRatio);

if (scaled_width <= 0 || scaled_height <= 0)
return;

_gw->resized( x(), y(), scaled_width,  scaled_height);
_gw->getEventQueue()->windowResize( x(), y(), scaled_width, 
scaled_height );

_gw->requestRedraw();
}

void GLWidget::moveEvent( QMoveEvent* event )
{
const QPoint& pos = event->pos();
int scaled_width = static_cast(width()*_devicePixelRatio);
int scaled_height = static_cast(height()*_devicePixelRatio);

if (scaled_width <= 0 || scaled_height <= 0)
return;

_gw->resized( pos.x(), pos.y(), scaled_width,  scaled_height );
_gw->getEventQueue()->windowResize( pos.x(), pos.y(), 
scaled_width,  scaled_height );

}

Without these checks nothing is rendered. Maybe this is the case for 
Android too?


hth,
Raymond

Hi,

I'm trying to run a simple application using OSG + Qt on Android.

I have successfully built OSG Release 3.4.0 for Android (armeabi-v7a) and it 
successfully runs on Android as expected (I have run the example 
osgAndroidExampleGLES2 and it runs flawlessly). I have also successfully built 
osgQt for my Qt version 5.7.0, as well as the osgViewerQt example for Android 
armeabi-v7a.

However if I run osgviewerQt on my Android device (version 5.0.2, API 21) it 
fails to render anything, in a way similar to what I found at the following 
link:

http://lists.qt-project.org/pipermail/interest/2015-July/017869.html

In order to simplify the application I allocate a single QWidget (instead of 
the four ones contained in the original osgviewerQt example) loading a single 
osg::Node* from a file cessna.osg. I have verified that the cessna.osg file is 
successfully loaded through a qDebug() logging message on the value of the 
loaded pointer. On my Android device I see the OSG-default blue screen without 
any object.

As an additional information: I have successfully built and executed the Qt 
examples with OpenGLES on my Android device.

I have done an extensive web search but I didn't find the solution to my 
problem, nor anyone that successfully ran OSG + Qt on Android.

Can anyone tell me where am I wrong, or what steps shall I follow to make my 
OSG+Qt application to work on Android?

Thank you in advance for your kind replies!

Andrea

Hi Raymond,

Unfortunately the output doesn't yet provide anything clearer to what
might be amiss.

Could you try the test with the env OSG_GL_ERROR_CHECKING set to
ONCE_PER_ATTRIBUTE, setting the env var to OSG_GL_ERROR_CHECKINGas
your specified will not change the setting, so will default to
ONCE_PER_FRAME.

Re: [osg-users] New LUA plugin fails to link

[Raymond de Vries]

Hi Robert,

Aha ok, I see. I thought that 3.2.1 was new enough to give it a try. I 
see the included sources now in the trunk... Obviously my trunk copy was 
not recent enough to notice it earlier.


I did a few tests and only from rev 14114 (From Stephan Huber, fix for 
building lua plugin from local source, to use the local sources), the 
lua plugin is configured properly (on windows) and shows up in visual 
studio. The result is the same, with the same link errors. So the issue 
has always been there on windows, I guess.

Hi Raymond,

Lua itself is pretty widely used and it's *very* portable being Anscii
C.  The new OSG Lua plugin includes the source and builds Lua locally
so there is no need to go chasing external dependencies.

The errors that Paul has published aren't to do with Lua but with
osgDB template methods that VisualStudio isn't handling correctly.

Robert.

The lua plugin has been checked in as it is for a couple of months
now, I'm surprised others haven't come across issues.  This suggest
something either not many Windows are building the OSG and reporting

build options you are using.

What compiler are you building with?  Are they any non default build
options you are using?  The Lua plugin doesn't have any specific GL
code in it so shouldn't be effect by GLCORE changes.  It might be
worth just trying a default build though to see if something odd
happens with GLCORE build.

As for multiple defines, these are template definitions provided by
include/osgDB/PropetyInterface that the compiler should be handling
just fine.  It could be that some extra option is required for it to
be a little more C++ compliant.

Hi,

Pfew, indeed it seems like the latest CMake does not work for me... 
Although I believe I had tried an older version before on this system, I 
tried it again (v2.8.9) and voila, that one worked! But in the mean 
time, I tried a lot of other things too so it might still be the 
combination of settings.


Thanks for your help.

It's only happened to me a couple of times and pressing build

I suppose you could try fiddling with the multiple project build

Also check to see if there is a custom build rule which is trying

[osg-users] Bit OT: building OSG on Windows 8?

[Raymond de Vries]

Hi guys,

It's OT but I do like to ask your help with building the OSG on Windows 
8. I was wondering if anyone can give me a hand with building the OSG on 
Windows 8. I have build OSG numerous times on any other platform but now 
I am trying to build the OSG (3.1.1 but that does not matter) on Windows 
8 using cmake 2.8.12.1 + VS2010 + WinSDK 7.1 (x86).


No matter what I try to do (disable UAC, take ownership, set ACL to Full 
Control), I keep getting Access is denied. for mt.exe. This is driving 
me pretty crazy...


Anyone else been in this situation and fixed it?

Thanks a lot,

We want to port an OSG program to Ipad. This was once written on Windows.
We already gathered some experience on OSG/GLES when porting it to
Android.
And now its time for IOS. We are completely fresh on IOS Mac programming,
though. So fresh, we don't even own a Mac for development station, yet.
In
preparation for the task I was looking on OSG site and mailing list for
some guidance. My overall impression is not too rosy, though. I've found
posts that CMake does not work with XCode and XCode project has a
separate
manually maintained repo. Since I am a such a newbie on the topic I can't
figure out how severe the whole picture is and how easy or messy attempt
could be. So I decided to just start a small poll and ask these few
questions directly:

CMake and XCode:

XCode is now distributed via the mac app store, the app resides in the
app-folder, and not as in previous versions in a dedicated folder called
/Developer Older versions of Cmake required that xcode lives in
/Developer. This broke project generation for xcode. Fortunately the
nightly builds available at cmake.org include a bug fix, so cmake is
working again for os x and ios.

CMake generated project files vs hand-maintained xcode-project files on
github (https://github.com/stmh/osg/tree/iphone


cmake:
+ project files for most of the plugins
- generated project files work either for the simulator or for the
device (you'll need two xcode project files for sim and device)
- no working example app

hand-maintained xcode-project-files via github branch:
+ project can compile libs for device and lib
+ project can be embedded in other xcode-project and xcode can resolve
all dependencies automatically.
+ working examples
- only a handful plugins are supported




- Is IOS/OSG environment mature enough to attempt a more advanced
application than test samples ?

I think it's stable enough to do serious work. AFAIK there are some apps
in the wild from Thomas Hogarth and I published a small app two weeks ago.


- For larger app would you recommend XCode or command line Cmake build ?

AFAIK It's necessary to use xcode for building an ipad app (codesigning
for example), but you can compile your xcode project from the
commandline using xcodebuild, which works good enough. I'd recommend
xcode.


- I have read that XCode can be quite unresponsive with OSG project on
Mac
mini. Could you recommend some minimal HW configuration to handle the
environment and allow for comfortable work ?

yes, that's true, xcode need a lot of cycles to open and munge the
osg-project files, you can avoid this by compiling the osg libs and
-plugins with xcodebuild via the command line; and, you'll do this only
once to get a set of libs you can use for your further development tasks.

So, basically you compile your osg libs and plugins once, set up your
project and use the libs from there. Working on your own project with
xcode is fast and flawless, so no worry about that. (linking will take
its time though)

A recent mac with plenty of RAM (xcode tends to use all available RAM it
can get) and a lot of cores :) will suffice. I think an midsized
quadcore iMac would be a good start. I do most of my development with a
two year old MacBookPro with 8GB RAM and a 256GB SSD and on a four year
old quad core Mac Pro.


- Can OSG/GLES program be tested on IPAD emulator on Mac ? We could not
do
it with Android (last week version of Android SDK  supposedly changes
that)
?

If you compile osg for simulator and device, and adjust the project
settings accordingly then you can test your app on the

Yes, my github mirror is currently not uptodate, I'll update it from
time to time. It's main purpose is the handmaintained xcode-project
whcih compiles out of the box (w/o the need of cmake) and has some
working examples.
Ok, clear, I thought that indeed. Last night, I tried it and it worked 
ok out of the box. Almost ok, though: I get unresolved symbols from 
freetype. Which freetype should I use, and how should I install that?


(sorry to ask newbie questions since I am still pretty new with Mac dev)


It's basically the same functionality Eduardo provides, no cmake needed,
working examples, handmaintained xcode-project file.

Ok, clear.

thanks
Raymond

Re: [osg-users] First OSG application on Ipad

[Raymond de Vries]

Hi,

Cool, 2 times succes: cmake is working properly now and finds Xcode:
- the upgrade of cmake was not done properly, some symlinks were still 
pointing to older versions. Fixed them by hand. (btw I needed to remove 
some other cmake related stuff by hand too)

- Installed Command Line Tools for Xcode - Late March 2012
(did not build yet)

osgIPhoneViewer now builds properly and starts (in simulator).

thanks a lot!
Raymond

In this mail, you mention that cmake nightly build should be usable. In

Now when I try to use cmake 2.8.8 by running 'cmake-gui .' from within

I ficed the freetype issue on github, do a git pull origin iphone and it

The previous freetype-lib worked only for the devie.

Hi Wojciech,

Am 20.04.12 17:28, schrieb Wojciech Lewandowski:


We want to port an OSG program to Ipad. This was once written on Windows.
We already gathered some experience on OSG/GLES when porting it to Android.
And now its time for IOS. We are completely fresh on IOS Mac programming,
though. So fresh, we don't even own a Mac for development station, yet. In
preparation for the task I was looking on OSG site and mailing list for
some guidance. My overall impression is not too rosy, though. I've found
posts that CMake does not work with XCode and XCode project has a separate
manually maintained repo. Since I am a such a newbie on the topic I can't
figure out how severe the whole picture is and how easy or messy attempt
could be. So I decided to just start a small poll and ask these few
questions directly:

CMake and XCode:

XCode is now distributed via the mac app store, the app resides in the
app-folder, and not as in previous versions in a dedicated folder called
/Developer Older versions of Cmake required that xcode lives in
/Developer. This broke project generation for xcode. Fortunately the
nightly builds available at cmake.org include a bug fix, so cmake is
working again for os x and ios.

CMake generated project files vs hand-maintained xcode-project files on
github (https://github.com/stmh/osg/tree/iphone


cmake:
+ project files for most of the plugins
- generated project files work either for the simulator or for the
device (you'll need two xcode project files for sim and device)
- no working example app

hand-maintained xcode-project-files via github branch:
+ project can compile libs for device and lib
+ project can be embedded in other xcode-project and xcode can resolve
all dependencies automatically.
+ working examples
- only a handful plugins are supported




- Is IOS/OSG environment mature enough to attempt a more advanced
application than test samples ?

I think it's stable enough to do serious work. AFAIK there are some apps
in the wild from Thomas Hogarth and I published a small app two weeks ago.


- For larger app would you recommend XCode or command line Cmake build ?

AFAIK It's necessary to use xcode for building an ipad app (codesigning
for example), but you can compile your xcode project from the
commandline using xcodebuild, which works good enough. I'd recommend xcode.


- I have read that XCode can be quite unresponsive with OSG project on Mac
mini. Could you recommend some minimal HW configuration to handle the
environment and allow for comfortable work ?

yes, that's true, xcode need a lot of cycles to open and munge the
osg-project files, you can avoid this by compiling the osg libs and
-plugins with xcodebuild via the command line; and, you'll do this only
once to get a set of libs you can use for your further development tasks.

So, basically you compile your osg libs and plugins once, set up your
project and use the libs from there. Working on your own project with
xcode is fast and flawless, so no worry about that. (linking will take
its time though)

A recent mac with plenty of RAM (xcode tends to use all available RAM it
can get) and a lot of cores :) will suffice. I think an midsized
quadcore iMac would be a good start. I do most of my development with a
two year old MacBookPro with 8GB RAM and a 256GB SSD and on a four year
old quad core Mac Pro.


- Can OSG/GLES program be tested on IPAD emulator on Mac ? We could not do
it with Android (last week version of Android SDK  supposedly changes that)
?

If you compile osg for simulator and device, and adjust the project
settings accordingly then you can test your app on the simulator and on
the device. In my experience the simulator is slower than the actual
device and you'll notice some artefacts/errors when rendering opengl es
from within the simulator.

I have a set of universal libs of osg which work for the device and for
the simulator. If there's any interest I can share them online. (Built
from the handmaintained xcode-project via github)

The hard part with osg + ios is to get a set of working libs for
simulator and device. If you have your libs and

Re: [osg-users] osgexport for blender?

Hi Martin,

I believe that you can use the blender osg exporter only up until 
version 2.49b, i.e. 2.5 and higher cannot be used.


Also, take into account (I got that info from Cedric) that the model 
needs to have up-to-date materials. The older materials are not exported.


good luck

Hi,

I am pretty new to MacOSX and I am trying to get a live image from the 
webcam on my MacBook Pro in osgmovie (osg 2.9.11). I have read that this 
should be possible with the quicktime plugin but on the other hand I see 
that the quicktime plugin is deprecated in favor of the imageio plugin. 
I built everything with x86_64 so I cannot use the quicktime plugin, if 
I read it correctly.


I build osg 2.9.11 with x86_64, imageio and Cocoa.

I tried to find info if it would be possible to fetch the webcam image 
with ffmpeg but I could not find such info. Anyone else?

Re: [osg-users] osganimationsolid example

Hi Gianni,

As far as I can see the euler animation is not working at all: no 
rotation. The euler animation is not 'routed', so to say. There are no 
'pre-defined' words or so, the words have to match for correct routing 
(like the 'position').

is string diven.

Example (from osganimationsolid):

 osgAnimation::Vec3LinearChannel* channelAnimation2 = new 
osgAnimation::Vec3LinearChannel;
 channelAnimation2-setTargetName(AnimatedCallback);
 channelAnimation2-setName(euler);
 
channelAnimation2-getOrCreateSampler()-getOrCreateKeyframeContainer()-push_back(osgAnimation::Vec3Keyframe(0,
 osg::Vec3(0,0,0)));
 
channelAnimation2-getOrCreateSampler()-getOrCreateKeyframeContainer()-push_back(osgAnimation::Vec3Keyframe(1.5,

 osgAnimation::Animation* anim2 = new osgAnimation::Animation;
 anim2-addChannel(channelAnimation2);
 anim2-setPlaymode(osgAnimation::Animation::LOOP);

So the name euler is the only way I see that states the channel values are 
related to a rotation. Is it correct? If so, where can I find the list of all strings 
available?

Hi Robert,

I am using osgAnimation more and more and it seems to me that at least 2 
examples are not working 100%:
- osganimationtimeline does not animate the diffuse material for the 
head, as far as I can see (nathan.osg)
- osganimationsolid does not animate the 2nd animation (euler), as far 
as I can see


It might still be the case that I don't understand osgAnimation 
correctly but wanted to report this anyway. Actually, I already sent a 
question to the list wrt osganimationtimeline (but no reply). I don't 
have enough experience yet to fix this at this moment.


Btw svn head gives the same results as 2.9.7.

Re: [osg-users] Developer release of OSG and VPB imminent, please test.

[Raymond de Vries]

Hi Robert,

Sure, good idea. Thnx for the motivation to bug Cedric :-P I'll do that, 
and I can try it out almost immediately.


Have fun.
Raymond

Hi Raymond,

I'll leave this to Cedric Pinson to pick up on.   If it's easy for him
to fix then I'll let him jump in an address it before I make the dev

next week.  Please chase Cedric up on this one though ;-)

Hi Robert,

I am using osgAnimation more and more and it seems to me that at least 2
examples are not working 100%:
- osganimationtimeline does not animate the diffuse material for the head,
as far as I can see (nathan.osg)
- osganimationsolid does not animate the 2nd animation (euler), as far as
I can see

It might still be the case that I don't understand osgAnimation correctly
but wanted to report this anyway. Actually, I already sent a question to the
list wrt osganimationtimeline (but no reply). I don't have enough experience
yet to fix this at this moment.

Btw svn head gives the same results as 2.9.7.

Oooo the silence...  Has anyone tested out svn/trunk for OSG and VPB

If there no negative feedback I'll have to assume everything is fine
just go ahead and tag this morning.  My plan is start pupping out dev

[osg-users] Best way to get transformation animations from 3dsmax into osgAnimation?

[Raymond de Vries]

Hi list,

I've got models which are modeled in 3dsmax and are exported with OSGExp 
to .ive or .osg. I have (transformation) animations in 3dsmax (8 or 9) 
which are then exported to AnimationPathCallbacks. When I load these in 
osg they are animating nicely. However, I would like to have detailed 
control over the animation playback and I have been struggling with the 
AnimationPathCallback, and could not make it work properly. Also, I 
would like to use the more advanced osgAnimation (I like it a lot so far).


Now I would like to use osgAnimation instead of the 
AnimationPathCallback. I have been trying the fbx format but I get very 
different results with the same scene (OSGExp compared to fbx exporter 
in 3dsmax 8/9) so currently I would like to take one step at the time, 
and prefer to use OSGExp and still convert to osgAnimation animations.


Does anyone have a working strategy how to accomplish this? E.g. is 
there a straight forward way to convert AnimationPathCallbacks into 
osgAnimation?


Cheers
Raymond

Re: [osg-users] Strange error only in debug mode

Hi,

Fyi, you can also remove a callback by using NULL, the ref counting 
would clean it up then. Would that help?

Thank you. I don't understand where is the error because in my program I simply

then it's very strange this output.
 

Then it could be possible that you are removing the callback while OSG
is in its update phase. Where are you calling removeUpdateCallback()?

Re: [osg-users] Using osgAnimation for material animation?

Hi Serge,

I am looking into nathan.osg and osganimationtimeline and see that the

that the diffuse value is being animated (checked the values).


Can you please confirm that this demo is supposed to work? I am using 
svn of both osg and osg-data.

Re: [osg-users] de-interleave with directshow plugin?

[osg-users] Multi-GPU on Windows 7, second window is black when the first window has focus?

[Raymond de Vries]

Hi osg-users,

I would like to report/ask a problem that I encounter when I use 2 
GeForce GTS 250 cards in my Windows 7 Home Premium 32 bit system. With 
all the combinations of enabled/disabled SLI and connected/disconnected 
SLI bridge, I get a black window on my 2nd monitor when I use osgviewer 
without arguments (and other programs that I tried). The second window 
is rendered ok when the first window does not have focus, i.e. when 
another program is on top of it.


I have tested with (this morning's) svn, 2.8.2 and 2.2.0 and they all 
behave the same. Built with VS2008, using the latest nvidia drivers.


Anyone have some tips?

Re: [osg-users] Multi-GPU on Windows 7, second window is black when the first window has focus?

[Raymond de Vries]

Hi J-S,

Fyi: I tried to go back in time w.r.t. nvidia drivers but the helpful 
(sigh...) windows update kept installing version 196.21 somehow...


I installed 196.34 (from laptopvideo2go) and the problem is still the same.

I do have the OpenGL knowledge but lack of time to dive into this.

Is it so that 2 windows are created by the osg, instead of 1 window that 
spans accros these 2 screens? It seems to me that that is the case, 
judging from what happens when you focus the window on the 2nd screen: 
the first window does not go to the top.


Is there a way to let the osg open just 1 window that spans accross the 
2 monitors?


Raymond


Jean-Sébastien Guay wrote:

Hi Raymond,


I hadn't noticed this because I always start up osgviewer fullscreen on
my second monitor only, or in a window.


And about this, I think this new problem might be related to the weird 
behavior I and others have noticed with OSG apps before:


- Start fullscreen on screen 0 : the app will show up, then the screen 
will turn black for a few seconds and then it will come back (annoying 
but it's ok after a few seconds).
- Start fullscreen on screen 1 : the app shows up and stays that way 
(that's how we'd like it to behave every time!)
- Start fullscreen on both screens : the app shows up on both screens, 
then the screen turns black for a few seconds, and the image comes 
back on the first screen but the second one stays black (that's the 
new problem, before the image came back on both screens after turning 
black).


So I think I'll submit a bug to nVidia in any case. It would be nice 
to have them look at it and see if there's a problem in their drivers 
that's causing this. I haven't seen this behavior on other apps (games 
for example) but those are generally hard-coded to work on only one 
screen (the first)...


If anyone with OpenGL knowledge would like to code up a quick straight 
OpenGL app that can start a graphics context in fullscreen and we can 
specify which screen or both, it would be interesting to see if this 
is reproducible then.

[Raymond de Vries]

Hi,

Good point. Just tried it and the results are even weirder (with 
classic): 2nd window *is* drawn but not correctly: it halts until focus 
is switched. And when going from 2nd window to 1st window (by setting 
focus) the rendering on the first window goes crazy: e.g. a rotating 
model will spin much faster. A little bit difficult to describe in words ;-)

   Hi,

   Ok, nice to hear. Which version of directx are you using? My
   directshow build on Vista, using directx August 2007,
resulted in
   a missing symbol...

  Hi guys,

  First of all, thanks a lot for your quick reply! As it
   turned out,
  I also had a more recent platform sdk on my system
(win vista).
  Out of habit I just installed the older one on each
system I
  develop on... And I had build the baseclasses once (long
   time ago)
  using the makefile...

  Thanks for your advice. I just built the BaseClasses
and now
  building osg svn, including directshow :-) Finders
crossed...

  I will try out the windows 7 sdk on my windows 7 machine
   soon too.

  Jason, ok, I understand it. Indeed I found your
message from a
  while ago. I only saw Cedric's name in the cmake
module, so
   that's
  why I thought you joined efforts. So thanks Cedric!

  One more thing for now: do I have (easy) access to
the 'current
  image' via the plugin?

  I will let you know how it goes...

  Cheers
  Raymond

  Hi Raymond,

  Just wanted to give credit to Cedric for the osg
DirectShow

  had sent out an email quite awhile about about
public

  in an
  open sourced Direct Show plugin but never got
around to
  releasing one.
   Kudos to Cedric for beating me to the punch :)

  Thanks,

Re: [osg-users] Trying out the directshow plugin - how to build the release version of BaseClasses?

[Raymond de Vries]

hmm, sweet. Incl multitouch :-)

Btw how do you do streaming with directshow? What do you use as server? 
Do you use a standard streaming protocol, or a custom one?
Btw2 how do I get the current image from the directshow? Do I need to 
get it from the texture, or is it possible to get it 'more low-level'? 
'more low-level is most likely better performing..


thnx for your thoughts

I believe if you do texture-getImage() you will get it. Howevere, you 
might need to do some syncing between the DirectShow Image update and 
your image lookup
But I wonder/doubt whether that is quick enough, I would like to process 
the image in realtime, as close to the source as possible. I know I can 
make a directshow filter and insert it into a directshow graph or so. 
But that would result in some dependancies that I don't want/like.
