If you don't see the blue screeen of OSG then it's exiting abnormally.

First: What version of OSG are you compiling? 3.1... trunk?
Second: What device are you using?
Third: What options did you use in Cmake?
Fourth: GLES1 or 2?

 Hi community,

 Have a look at the part of the OSG documentation about the Neon
 instruction support. If you are running the code on a device with a Tegra 2
 chipset (maybe some others), then it will cause this type of crash because
 that instruction set isn't supported on Tegra 2. Either compile for the
 version 5 ABI (armeabi - which doesn't use Neon) or disable the Neon
 instruction set according to the instructions in the doc.



 I went thru the code and I am not seeing where the models are loaded (or
 is it interactive via menu or such).


 It is interactive, in the menu you have load model, then you type the path
 to the model file into a popup window (.ive) there, e.g.
 /mnt/sdcard/cube.ive. If everything goes well, the model will load and
 display.


 Please note I know OSG to some point but new to mobile device development
 so please talk to me as to a child on this. Shell I copy the models
 somewhere so they are loaded?


 For the demos you should likely put the models somewhere on the sdcard
 because you will have to enter that path in the file loading dialog.


 What is the assets folder for?


 That folder contains additional files (assets), such as models, sounds,
 icons, etc. that get packaged into the application APK and installed with
 it when you install the application. Then you can access them from the Java
 code using handles. Don't put your models there, it isn't possible to
 directly load files from C++ code using that folder. Well, strictly
 speaking it is possible, but it requires some major hacking to discover
 the Linux filesystem path of the folder before you can access files there.

 Have a look at the Android SDK documentation, it explains what are these
 various folders for and how an Android application works. Starting mobile
 app development with OSG as your first project is a really terrible idea
 due to the complexity - try some of the SDK examples first, then the
 examples from the NDK so that you understand how things fit together.

 Jan

Re: [osg-users] build osgmotionblur

2013-04-11 Thread Robert Osfield

HI Alfonso,

The osgmitionblur example is written to demonstrate use of the OpenGL
accumulation buffer. If you driver doesn't support the accumulator buffer
then it won't work.  However, I would expect it to compile.  What platform
and OpenGL version are you working with?

Robert.

 Hi,

 I've been using OSG successfully for a while now. Unlike all other
 examples I've tried, example osgmotionblur uses OpenGL functions and I'm
 not able to build it. Should I install and include OpenGL library too?
 Also, I could replace glClearColor and glClear with OSG's counterparts, but
 I don't know how to replace glAccum.

 Thanks for the help.

Hi Michael,

 That did the trick! I moved applyModeList and applyAttributeList down
 right before if(_shaderCompositionEnabled).

 I don't know if it produces any side effects. I tried running my
 application on top of the change and didn't notice anything. It uses
 osgEarth and Wang Rui's EffectCompositor and renders in HDR and also has a
 few 3D models loaded, so I would say that a fair deal of the code has been
 exercised.

 If you don't have any objections I will make a submission.
 Thank you again.


Good to hear the change fixed the problem.  I can't think of any problems
off hand but we'll need to roll the changes out for the wider community to
test to see if there might be some odd corner case, but right now I think
we should be safe.  So post the change to osg-submission.

http://www.openscenegraph.com/index.php/documentation/platform-specifics/android/43-building-openscenegraph-for-android-3-0-2
(the

in -DANDROID_ABI select only armeabi (remove the other ABI)

Make sure to disable the optimizations:
-DANDROID_OPTIM_NEON
-DANDROID_OPTIM_ARM32

These things are an optional part of the ARM spec and not every chip
manufacturer decides to include them in their CPUs. If you try to run code
using these instructions on a CPU that doesn't support it, Linux kernel
will kill your process with an invalid instruction signal - typically
either SIGBUS or SIGILL = app crashes without any messages. You should
check the log viewer in Eclipse (don't forget to disable any filters!) and
look for a crash there.

Well, I don't want to sound too harsh, but if *you* don't have time to
actually read the documentation and go through the tutorials, why do you
think people on the list should have time to support you? Especially as the
question above is really a FAQ issue that was addressed on the list in the
past. Also basic things like actually checking why it crashed in the log
and finding the stack trace are well documented in the Android SDK/NDK
documentation. We have our own jobs to do as well, you know.

Re: [osg-users] osgAndroidExample

Hi Jan,

Good question. That is the purpose of the community I guess. While back
when while I was more active with this list I used to support people just
because. Also, I work as freelance so I know that all the knowledge gained
here or there is valuable and is worth of money. It is based on the
supportive attitude I believe people from this list have.

So far you get me by only two emails insights into area which is new to me
and I am thankful. And I am willing to share it with all the new comers
since there are some undocumented stuff or it is not clear where the specs
and docs are located and this knowledge is spread among the highlanders
from the community who have spent the time ( which I don't have at the
moment and that was the reason for me to address the community ) and money
and again, it has some commercal value as well. I think as a freelance
contractor I have the understanding for all you wanned to address.

Thanks again for the time you spent and the know how you shared with me -

[osg-users] Confused by rendering loop

2013-04-11 Thread Paul Heraty

Hi,

I'm using some profiling tools to try to understand how to optimize an OSG 
application built on osgviewer. In fact, for the purpose of this question, I am 
just running osgview cow.osg.

When I look at the rendering calls, I can see that glDrawArrays get's called 
around 4000 times at application startup, but this quickly drops down to 0 
calls after about 1 second. I can see that there are ~1500 vertices reported, 
but this number also drops off to zero after 1 second.

However, I can see that the GPU cores are kept busy constantly, and I achieve a 
frame rate of 120fps after an initial ramp of about 1s also (corresponds to the 
drop off in dlDraw calls).

What confuses me most is that I would expect the nmuber of glDrawArray calls to 
remain relatively constant throughout the application lifetime, as the cow data 
model is not changing.

Am I missing something?

Thank you!

Cheers,
Paul

Hi Paul,

By default the OSG usages display lists that have to be compiled once at
start up and then are reused there after so that subsequent glDrawArray
calls are avoided.

 HI,

 I have built all from scratch with the suggested armeabi only, and the
 same results. Interesting what I am seeing is when I do

 $ANDROID_SDK/tools/android list targets

 I see only two targets and both for armeabi-v7a . can this be an issue?

Re: [osg-users] osgAndroidExample

BTW el HTC wildfire seems that has a Qualcomm Armeabi V11 processor of the
low end so i would not use armeabi-v7 and go for armeabi ABI. Btw i had one
a device with similar specs and i can only say that you are going to suffer
a little bit, so... my condolences. Ah... try to check the Logcat, maybe we
can help more with the verbose exit

behavior .. Starts for a while, I can even press the Light On/OFF button
but no blusih osg screen :/  I got this development machine somewhat
setup so I am doing now all the setup based on specs, docs (as Jan

That means that you haven't installed more libraries for different targets
in the SDK. But that shouldn't be a problem normally. OSG is compiled using
the NDK, not the SDK tools (they compile Java code), so that command's
output is not really relevant.

However, check your log - that will tell you why did it crash. The reason
could pretty well be something else than Neon support - only the Nvidia
Tegra 2 lacks it from the common chipsets on the market.

OSG runs with no problem with the armeabi-v7a too. The idea of compiling
for the older armeabi is to avoid any potential problems with the optional
Neon instruction support that your hardware may not have (armeabi doesn't
contain those instructions).and any other compatibility issues your CPU may
have, as not all ARMs are the same. The old v. 5 armeabi is compatible with
practically everything on the market, the newer v. 7 ABI works with most,
but then you have to be careful about compilation switches (Neon/no Neon,
optimalization, etc.) because not every chip support every optional feature
in that ABI. So if you aren't sure, stick with the old armeabi.

Re: [osg-users] osgAndroidExample

Hi Jan,

I am setting up properly now everything from scratch, reading all over web
... I want to be sure and to learn how to setup the dev env first. Eclipse
is something new to me (Visual Studio and vi guy till now :) ..), as well
android as you already know. How to set up the build to use v5? I assume
the NDK have all the platforms (as Jorge mentioned somewhere in the
conversation). Any hints on this?

Thanks again a bunch

Nick

 OSG runs with no problem with the armeabi-v7a too. The idea of compiling
 for the older armeabi is to avoid any potential problems with the optional
 Neon instruction support that your hardware may not have (armeabi doesn't
 contain those instructions).and any other compatibility issues your CPU may
 have, as not all ARMs are the same. The old v. 5 armeabi is compatible with
 practically everything on the market, the newer v. 7 ABI works with most,
 but then you have to be careful about compilation switches (Neon/no Neon,
 optimalization, etc.) because not every chip support every optional feature
 in that ABI. So if you aren't sure, stick with the old armeabi.

 Regards,

 Jan

Just a question. Can the 3rd party libs be compiled with some switches? Are
you using the one pre-built available on wiki?

Re: [osg-users] osgAndroidExample

It varies from the NDK that things are build and Eclipse version (? I am
sure something behind it).

With the latest NDK r8e when I build the sample it says:
Fatal error: invalid -march= option: `armv5te'

any clue?

It is just a switch for gcc telling it which ABI to use. That is what 
you set when defining the -DANDROID_ABI variable - only keep the 
'armeabi' value there.

I am using those on the Wiki.

However, do check the Logcat for any errors - if the app crashes or is 
killed, the stacktrace in the log will tell you why that happened. 
Unless  you retrieve the stack trace from there we are just shooting in 
the dark. The problem could be something entirely different from the 
ABI/Neon issues even though this is a most common cause why the examples 
crash.

But how does it work?

[osg-users] osgEarth 2.4 is now available!

2013-04-11 Thread Glenn Waldron

Friends,
I am happy to announce that osgEarth 2.4 has arrived!

osgEarth is a terrain engine SDK built on top of OpenSceneGraph. You can
read the 2.4 Release Notes here: http://goo.gl/JVpQN

Along with this release, we are making a couple of administrative changes
as well. First, we are retiring the old trac-based wiki and moving to a
new GitHub landing page (http://osgearth.org). We'll dress it up with some
pretty pictures later.

More importantly, we have a new Documentation Site hosted on ReadTheDocs (
http://docs.osgearth.org). The docs are in the osgEarth GitHub repository
itself - which means that not only are they versioned, but that our loyal
community of users can help us keep them up to date.

As always - thank you for your support!

 Hi Jorge, Jan,

 I can not build it now with the ndk I downloaded - my dev machine is
 setup based on the wiki page by Jorge with the latest ndk. It says: Fatal

 Are you using the one pre-built available on wiki?


 I am using those on the Wiki.

 However, do check the Logcat for any errors - if the app crashes or
 is killed, the stacktrace in the log will tell you why that happened.
 Unless  you retrieve the stack trace from there we are just shooting in 
 the
 dark. The problem could be something entirely different from the ABI/Neon
 issues even though this is a most common cause why the examples crash.

 Jan

Hi Jan,

after some reading from web I managed to set the build (and understand some
of the background and terminology) to use armeabi version 5 for all the
builds. So the build should be ok, just to see why is still crashing.
Progress for this day :-). And thanks to you and Jorge.

Cheers,

Nick

[osg-users] reading dem/image files...

All,

I'm attempting to load a height field by using

osg::HeightField *grid = osgDB::readHeightFieldFile(...)

where the file is a gdal supported dem/image file format. When I attempt
to read the file, I'm getting the error

Warning: could not find plugin to read objects from file...

Is this because readHeightFieldFile() doesn't support the formats gdal
supports or is there something wrong with my environment so that my
plugins aren't loading correctly?

My environment is window 7 and OSG 3.0.1...

Thanks,
-Shayne
