Re: [osg-users] Converting PrimitiveSet to use triangles instead of triangle strips / fans?

[Jordi Torres]

Hi,

There is an option in the obj plugin to avoid tristrips. It's probably
better to try this cause tristripping is not cheap depending on the
geometry.

>From the top of my head is something like "noTrisStripPolygons".

Hope it helps.

Hi Hartwig​,

Indeed, I've gone ahead and unpublished the two links to mercurial and svn

Just ping if you see more content that should be reviewed/updated.

Hi Hartwig, Julien et al

Trac server is no longer available. It's dismantled.

We should change the links in the website to
https://codedocs.xyz/openscenegraph/OpenSceneGraph/ which is tracking the
master and building the documentation.

Hi Robert,

So just comenting the lines referring to those libraries in the
FindOpenCascade.cmake file did the trick. Also tested with a few igs files
and all worked ok.
So not sure for your opencascade version these libraries are needed to
build or/and run, but definitely not needed for me (installed from apt).

Could it be version dependent issues?

Cheers.

No I don't have this dependency in my system, fresh build. In fact

OPENCASCADE_TKDCAF is part from the package oce-draw, so CMake does not
find it automatically. But OPENCASCADE_TKVCAF is definitely not there.

Can you tell me what packages do you have installed w.r.t opencascade?
Maybe a newer version?

BTW Is probable that we don't need all the libraries here:
https://github.com/openscenegraph/OpenSceneGraph/blob/master/CMakeModules/FindOpenCascade.cmake#L57-L112
to build the plugin.

Cheers.

Hi Romulo,

You can use TangentSpaceGenerator to get the values of the T B and N. Here
you have a code example:
https://github.com/sketchfab/osg/blob/5d35b2a2d55e92b4c736ea5edcd9eeedf9ea6786/src/osgPlugins/gles/TangentSpaceVisitor.cpp#L46

Hi Julien, Robert et al.

I'll be out next week, but my plan is to start testing as soon as I get to
my computer.
We have a wide variety of animation models to test, so I hope we can help
in this topic.

Sorry for not being able to add any feedback these days.

Cheers.

[osg-users] Possible PolytopeIntersector bug?

[Jordi Torres]

Hi Robert,

I'm not sure PolytopeIntersector has en error here:

https://github.com/openscenegraph/OpenSceneGraph/blob/master/src/osgUtil/PolytopeIntersector.cpp#L186

I think it returns false when the whole polytope goes through a triangle.
In previous versions it was some code checking that.

Re: [osg-users] Some issues with the OSG website

[Jordi Torres]

Hey Chris,

The old trac is down again. I will try to restart it one more time, but it
is coming the day to get rid of it.
Maybe the only valuable information that it's not in the current website is
the tutorials part, which are pretty outdated these days.

I will remove Paul from professional services and don't hesitate to ping me
whatever issue you see.

Thanks for the heads up.

Humnm, we can have different coverity scan branches if we want to analyze
several releases. Anyway is no problem for me to wait to 3.6 :).

For faster intersections it is far better to build the kdtree first. Also
splitting your huge geometry in several could help to traverse the graph in
case you don't want to use kdtrees.

Cheers.

Hi Robert,

I'm ok to change the name. My concern was more about losing functionality.

It used to work meaning that one could target only lines, or points, or
triangles or a combination of them. Now that seems not possible.

Also I'm getting repeated intersection points for some intersections, but I
need to test it further.

I'll keep you posted.

[osg-users] Dimension Mask in PolytopeIntersector still working?

[Jordi Torres]

Hi Robert,

With your last changes about Polytope Intersection I'm not sure wether
dimensionmask is still used. A quick grep does not reveal any use of
_dimensionMask in the intersection proccess or getDimensionMask method in
PolytopeIntersector.

Am I missing something?

Re: [osg-users] [forum] Using OSG after a very long hiatus

[Jordi Torres]

Hi Rodrigo,

Not sure which tutorials are you following, but if you are looking at
trac.openscenegraph.org yes, they are totally out of date. Probably we
should think in finally remove the trac. All the resources are now in
www.openscenegraph.org. Also and a part from the books which are a great
resource, ( by the way you can get an electronic copy so you can read in
your screen, copy/paste etc ) I would suggest to follow Robert's advice and
learn from the examples. IMO is the best/first place to look in order to
understand better an OSG feature.

Cheers.

Re: [osg-users] Latest OSG cannot realize viewer under Android

[Jordi Torres]

Hi Michael,

I'm sorry I don't have the time now to dig into the problems you have. But
I strongly recommend you base your work in
http://www.openscenegraph.org/index.php/documentation/platform-specifics/android/178-building-openscenegraph-for-android-3-4,
I've tested it a number of times with success. Then you can make use of
osgAndroid if you target GL_ES 1 ( https://github.com/miragetech/osgAndroid ).
If GL_ES 2 is a must you are on your own, but I tested it with success some
time ago.

Cheers.

Maybe we could upload the OSG succesful builds in travis CI to docker. And
then pull it from osgQt build. I will need to figure out how to do this but
it cuold be an option.

Re: [osg-users] [build] Where to obtain dependencies for Ubuntu

[Jordi Torres]

BTW, the information in http://www.openscenegraph.org/index.php/download-
section/dependencies is also outdated.  And the prepackaged deps for debian
are now 10 years old
http://download.gna.org/underware/openscenegraph/gnulinux/debian/  :O. So
definitely the best would be to install directly from apt.

You can add yourself to the project as an observer/defect viewer. Otherwise
you also can ask for permissions as a contributor. Me or Robert will add
you as soon as you ask for it.

Re: [osg-users] OpenSceneGraph Travis + Coverity scan up and running

[Jordi Torres]

Hi Jason,

It seems your coverity scan build is not being launched. Instead of this
the "script" tag command is the one running.
Take a look at
https://github.com/openscenegraph/OpenSceneGraph/blob/master/.travis.yml#L52,
the "normal" build should not be launched if you are in the
coverity_branch.
Also your project should be easier to configure as you are not running
MacOSX builds, so you are not using a matrix for travis. So in a first look
I cannot spot anything weird, but make sure the indentation is correct, as
it seems to be important.

I'm happy to help if I can so feel free to contact me.

Cheers.

Hi Robert,

Great, so now we have continuous integration and it can be checked in
https://travis-ci.org/openscenegraph/OpenSceneGraph . I just created a PR
to add the status label to github site. And it seems it is working so far
because it started a build with my last PR :).

Re: [osg-users] Setting up travis for OSG in github

[Jordi Torres]

Hi Robert,

I just sent a PR for adding travis for trusty and OSX builds. It could be
improved adding missing dependencies like gdal, etc. to the apt/brew
section.
Once you logged in to travis and set it up for the osg github repo ( it's
only a few steps ), it will automatically search for the .travis.yml file
and start to make builds on each pull request or push.

You can also add a status label to the repo website to know if the build is
passing (https://docs.travis-ci.com/user/status-images/).

Cheers.

Hi Robert,

Let me do some tests in my own fork of OSG in github, once I have it
working I will send a submission with the needed files and instructions to
set it up.
If anyone in the community has experience using travis with C++ don't
hesitate to chime in :).

Cheers.

Re: [osg-users] Setting up travis for OSG in github

[Jordi Torres]

Hi Robert,

Travis is completely integrated with github, so when a build fails you are
totally aware, also it works for pull requests, so automatically you can
know if a PR breaks the build ( in a specific OS or in all of them ).
Also you don't need dedicated machines from community folks to run the
builds, AFAIK travis do provides them, and is able to run the builds for
different OS. Also you can run it with docker images.
For sure there are a lot of features I don't know enough, but IMO is a step
beyond Cdash for github hosted projects.

[osg-users] Setting up travis for OSG in github

[Jordi Torres]

Hi Robert et al.

It could be a good idea to setup a travis build for PR's and after each
push in github.
( https://docs.travis-ci.com/user/languages/cpp )

Many projects use it and it is really useful to detect build brakages or
failing tests. Maybe others in the community have some experience setting
it up for C++. For osgjs ( javascript ) it works nicely.

Thoughts?

Re: [osg-users] How does PIXEL_SIZE_ON_SCREEN work

[Jordi Torres]

Hi Bruno,


We also work with pointclouds in PointCloudViz ( www.pointcloudviz.com ) :)


2016-05-17 11:08 GMT+02:00 Bruno Oliveira <bruno.manata.olive...@gmail.com>:

> I am rendering point clouds.

In the document I sent it states for PIXEL_SIZE_ON_SCREEN :
"The current screen-space extent that OSG uses in this mode is determined
by constructing a sphere that contains all of the model in question, then
3D projecting the diameter of the sphere into screen space and measuring
the diameter in pixels."

With respect to that it could be argued that a sphere projected in
ScreenSpace ( perspective ) is an ellipse so it has 2 diameters. Anyway
that measures are kind of orientative if you think in the major diameter it
will work. So you need to assign ranges to your LOD's based on this
assumption. You can try values ( i.e. from 500 to 1000 ) and tweak them
iteratively.

Anyway if you need a better understanding take a look to the traverse
method of PagedLOD node (
https://github.com/openscenegraph/OpenSceneGraph/blob/master/src/osg/PagedLOD.cpp#L125
)

Hope it helps.

[osg-users] Possibility of a OSG 3.4.1 Release

[Jordi Torres]

Hi Robert,

It has been a while since last stable OSG version ( July 2015 ). And a
bunch of bugfixes has been added to the 3.4 branch.

So... Can we ask for a 3.4.1 stable release?

Thank you!

Re: [osg-users] dumptruck.osg and GL ES 2.0

Hi Jens,

It is definitely possible, with some minor fixes. I did it for a client
app. Now we updated to 3.4. Anyway give a look to
https://github.com/cedricpinson/osg, there is where the main development of
the gles/osgjs plugin is done, and it has a lot of improvements w.r.t osg
official repo. It should be merged sooner than later, but it could be worth
to keep an eye.

Cheers.

Hi Chris,

I don't think this is possible as you need to confirm the subscription with
a link provided by the list. So it would be really weird if this is the
case.

Re: [osg-users] dumptruck.osg and GL ES 2.0

[Jordi Torres]

Hi Jens,

Maybe you can try the gles pseudoloader. It optimizes models to be
compatible with gles. So when you read a model add ".gles" at the end to
use the pseudoloader.

Cheers.

Re: [osg-users] dumptruck.osg and GL ES 2.0

[Jordi Torres]

Yep,

The gles plugin is a work done in the scope of the osgjs exporter ( webGL )
by Cedric Pinson and his team. It works really nice for webGL exported
scenes so it should work as well for GLES.

Cheers.

Re: [osg-users] [forum] "Request received" emails

[Jordi Torres]

Hi Sebastian,

IMO it probably is a ML user with securesever mail reaching his quota or
whatever, I know nothing about securesever, but it seems it belongs to
goddady. So maybe we can write to them, but I don't expect they to fix it.
Filtering as spam is my best idea though.

Re: [osg-users] Mac compilation error

Hi Robert,

The svn is connected to github but not the opposite. So if you do a commit
in github it is not updated in the svn.
So now it is not syncrhonized.

Re: [osg-users] Updating the Open Scene Graph Wiki

[Jordi Torres]

Hi Michael,

I did not receive any email from you ( also not in my spam folder ). Which
site are your trying to access? I guess you are looking at
trac.openscenegraph.org. That website is totally outdated and is there only
for historical/backup purposes.

Take a look to www.openscenegraph.org, there you should see updated
documentation. Anyway if you stil want to edit the information feel free to
send me an email with your username. Do yourself an account first (
http://www.openscenegraph.org/index.php/login )

Thanks.

Re: [osg-users] [osgPlugins] Trouble with texture to export to OSGJS format

[Jordi Torres]

Ok I will try to be clerarer:

1. Can you please share the ive model or a part of it to debug the crash?
Otherwise is almost impossible to know what is happening.

2. Tga textures are not supported in the browser, you'll need to write them
out to jpg.

3. You *must use the gles *pseudo-reader to avoid the Fatal nb colors.

4. Did you try the inline images feature? Did it work?

  Cheers.


 Well, I can show this very simple example with one IVE and 2 texture
 files.

 I cannot convert directly to OSGJS format.
 IVE -- OSGJS does not work (Fatal nb colors log)
 IVE -- OSG works
 OSG -- OSGJS does not work (Fatal nb colors log)
 OSG -- OBJ works
 OBJ -- OSGJS works but I have 2 logs saying that some faces were reversed
 by the plugin
 And if I try to load this model (with the textures in a folder \\images at
 the same location of the java script file) I cannot see the texture. Chrome
 moans:
 warning use white texture as fallback instead of images\tree_03.tga

 Thanks in advance !
 Mathieu

 mathieu.rouge...@telespazio.com:

 Hello Jordi, thanks a lot for your answer.

 I tried to use the gles plugin with the command described in the link you
 sent, but osgconv.exe crashes (no log message).


 Could you share the model, or a part of it to reproduce the crash? That
 will help to debug.

  I tried with an IVE and an OSGB files as input.


 So far the only way I have not to receive the error (Fatal nb colors 1 !=
 1349) is to get an OBJ from the graphist without texture. Texture files are
 in a separate folder /images.
 Then I can convert to an OSGJS format.
 In this file I have references to the textures in some fields, such as:
 File: images\\base_age.tga,

 But when I load it, even if I put textures in the folder //images, they
 do not appear.
 And in the Chrome console I have this:
 warning use white texture as fallback instead of images\valve.tga
 warning use white texture as fallback instead of images\alu_txt.tga
 and so on...

 That message means that osgjs is not founding the textures. Are you using
 a server like apache or similar? It is a must to work with separate
 textures, also the textures should be in the route they appear in the osgjs
 file.

 By the way did you try the inline textures feature?

 Cheers.

Re: [osg-users] [osgPlugins] Trouble with texture to export to OSGJS format

[Jordi Torres]

Hi Mathieu,

You should use the gles plugin to export to avoid the Fatal nb colors error.
See: https://github.com/cedricpinson/osgjs/wiki/Convert-model-with-OSG.

For the images:

You can try to convert first your model to osgb and write the textures to
disk and then convert to osgjs using $osgconv file.osgb.gles file.osgjs, if
the osgjs plugin is not writting to disk the images.
Also you can save them as inline images in the same osgjs file. The
resultant file will be bigger though, but it is ok for quick tests. For
example drag  dropping here http://webkeux.com/osgjs-test/

One more thing, if you have the images as separate files you *must *use a
server (http server I mean).

Cheers.

 Good morning,

 I'm hardly trying to export a 3d model to OSGJS format but I have trouble
 with the textures. Concretely the textures do not appear in the OSGJS
 output file.

 What I did:

 1) initially I had an IVE file that an infographist gave me. I tried the
 two commands osgconv File.ive File.osgjs.
 I got this return:
 Fatal nb colors 1 != 1349
 can't save osgjs file
 Unable to write to output stream

 Idem with osgconv -O OutputTextureFiles File.ive File.osgjs

 2) I tried (just for test) to convert the ive file to osg format. It works
 but the output file has no texture.

 3) I asked the infographist to export the model to OBJ format with 3dsMAX.
 So I got an OBJ file and a MTL file.
 Then I do osgconv -O OutputTextureFiles File.obj File.osgjs
 I get some warnings such as

 *** line not handled *** :map_refl
 C:\myFolder\myFolder2\maps\refmap_txt.jpg
 Warning: [ReaderWriterOBJ::convertElementListToGeometry] Some faces from
 geometry '' were reversed by the plugin

 Strange because the JPG file really exists in my fodler ! I have other JPG
 files and I have no warning message for them.
 Anyway, I do not think it is the source of the problem.
 But the final OSGJS does not appear with textures, as no texture is
 exported. The geometry is correct.



 Apparently I did something wrong, but I don't know where !
 If someone has an idea about this export issue ?


 Thanks a lot and have a good day,
 Mathieu

Hi Joe,

Take a look to this thread,

 Hi Joe,


  Hi :)
 Ive been struglling in simplifing a model.
 I have the simplifier osgUtil gives. But from a sample ratio and on - it
 just doesnt simplify anymore.
 I have a model which a sample ratio of 0.5 and 0.01 gives the same result.

 Have you tried to change the maximError and maximumLength?


 I relised it was because osg has standarts for not destroying a model. I
 dont care about destroying a model..
 Is there a way to aggresivly simplify a model with no limits ? (Inside
 osg.. Without using other softwares)
 Thanks :)

 You can't simplify without some kind of metrics. Usually a simplified
 model should roughly resemble the shape of the original model.
 If you need a really really cheap representation for the distance you
 could use impostors. (see the osgimpostor example in the sources)

 Cheers
 Sebastian

  Joe.

That's exactly what I was referring. Just tested and it works for me in a
fresh install of Ubuntu 15.04. Also compiled with success for Android ndk

Should'nt these lines ( 34 and 36 ) be removed too?

Hi Robert and Rafa,

I just see this change was introduced by Christian Kehl (
http://comments.gmane.org/gmane.comp.graphics.openscenegraph.cvs/12859) but
probably he had a little mess in his computer when doing this change (As he
also stated later ). It is possible it might be not necessary.

Maybe Christian can comment something.

 Hi Robert,
 I did a couple of builds one for MacOSX 10.10 and for android gles1. For
 macosx everything worked so far but for android I'm getting this error
 using the toolchain:

 osg-trunk/include/osg/GLDefines:35:21: error: conflicting declaration
 'typedef GLfloat GLdouble'

 I suspect this is the same problem others has spotted. I think you
 suggested to do a better identification in cmake, or maybe just check if
 the symbol already exists in that header. I'll try to provide a fix later
 today.

 Hi Jannik,

 A quick reply as I am replying on my phone. My intention was to introduce
 the same technique as osg::Node::asTransform() to avoid the dynamic cast,
 but only do this if there was a noticeable performance regression.

 The 20% regression you've seen could qualify. Is this with a release
 build?

 As general note, I suspect you are over using callbacks.

 On 8 Jun 2015 17:16, Jannik Heller scr...@baseoftrash.de wrote:

 Hi Robert,

 I tried my application using the latest trunk and didn't notice any
 functional regressions.

 However, I did notice a performance decrease in the Update phase of
 about 20%, compared to OSG 3.2.0. This had me a bit concerned, so I digged
 through the changes and found commit
 https://github.com/openscenegraph/osg/commit/e967420323bb6e500425144cb305cf8060c1c515
 .
 Since that commit, we now get *four* dynamic_cast's per frame and
 NodeCallback, which I suspect is causing the slowdown. Two dynamic_cast's
 are in NodeCallback::run, then another two in NodeCallback::traverse.

 Changing to the non-deprecated Callback instead of NodeCallback gives a
 slight improvement with now just two dynamic_cast's in Callback::traverse,
 but still isn't optimal.

 Ideally, the application should be able to decide on the level of safety
 vs. level of performance it needs. If a Callback is only intended to be
 used on Nodes, there is little point in dynamic_casting to Node every frame.

 I think I can workaround the casts by using a custom class derived from
 osg::Callback as the base class for all my node callbacks. Still, it's
 quite a peculiar situation that does affect all users of the OSG.

 I guess my question comes down to, are there any plans on optimizing the
 Callback code before a final 3.4 release? If you aren't convinced, I can
 throw together a repro case and some profiling data, but I think the impact
 of 4 dynamic_cast's per frame and NodeCallback should be obvious.

 Cheers,
 Jannik

Hi Christian


 Then how do I use the toolchain file for compiling examples that are
 imported in Eclipse ? I don't fully understand the toolchain
 mechanism further than basically compiling the libraries
 (which went successfull so far).


The toolchain stuff is only to compile the libraries. I will test from

time ago.

Sorry for not being too active Anyway, did you try to compile all with
the last additions from Rafa Gaitán? Now it is possible to compile OSG for
Android with dynamic libraries, take a look to
http://www.openscenegraph.org/index.php/documentation/platform-specifics/android/178-building-openscenegraph-for-android-3-4
.
Is a must for you to use static libs? You can try the dynamic version,
maybe it solves your problems.

Also we are using osgAndroid ( https://gitorious.org/osgandroid/pages/Home
) maybe it could be helpful.

I'm building now OSG for Android to do some testing.

I hope I can help a bit later.

 It could be also a bug  in the Android port of OSG. OSG is designed to
 load plugins required to load the various data formats dynamically.
 Unfortunately, this doesn't really work well with Android because of the
 way Android applications are deployed, so OSG won't find its plugins (and
 models/textures/etc won't load).

 Jordi Torres has implemented a workaround using static linking, that is
 what those plugin declaration macros were for. If you have compiled
 everything statically as described in the doc and it is still looking for
 .so files (DLLs in Windows parlance), then something seems borked in the
 osgDB plugin system, IMHO.

 Do the osgAndroid examples shipped with OSG work for you? If those don't
 work neither, then something has changed in OSG and broke it since mid-2013
 when I have last compiled the Android version (and when it was working).

 J.

 the android wrapping system to fix the problem myself. The problem has
 to be
 in the static libraries, but where ?



 It could be also a bug  in the Android port of OSG. OSG is designed to
 load plugins required to load the various data formats dynamically.
 Unfortunately, this doesn't really work well with Android because of the
 way Android applications are deployed, so OSG won't find its plugins (and
 models/textures/etc won't load).

 Jordi Torres has implemented a workaround using static linking, that is
 what those plugin declaration macros were for. If you have compiled
 everything statically as described in the doc and it is still looking for
 .so files (DLLs in Windows parlance), then something seems borked in the
 osgDB plugin system, IMHO.

 Do the osgAndroid examples shipped with OSG work for you? If those don't
 work neither, then something has changed in OSG and broke it since mid-2013
 when I have last compiled the Android version (and when it was working).

 J.

AFAIK There is not a bug tracker for OSG. The trac is not open for

Re: [osg-users] where is the Dashboard ?

[Jordi Torres]

Hi Mattias,

The correct link for the cdash machine is
http://cdash.openscenegraph.org/index.php?project=OpenSceneGraph. Last
activity was in september this year (
http://cdash.openscenegraph.org/index.php?project=OpenSceneGraphdate=2014-09-19
)

In the main website there is a post about contributing to the
OpenSceneGraph CDASH instance (
http://www.openscenegraph.org/index.php/community/cdash ). At the moment we
don't have any dedicated machine doing builds for OSG. Anyway, anyone can
publish to the public dashboard following the link instructions.

Cheers.

 Hi people,

 I was looking at some really awkward cmake code in out top-level
 CMakeLists.txt. It is awkward because will still support cmake-2.4
 which (if I remember correctly) is mostly because this is the cmake
 version that comes with RHEL5. So I decided to have a look at the
 CDash to see how existing RHEL5 computers are doing these days.

 http://my.cdash.org/index.php?project=OpenSceneGraph

 There are no builds whatsoever...for the last 2 years. Is this the
 correct link? We don't have a single computer doing nightly builds?

Re: [osg-users] Building OSG for Android using a toolchain and fixes for loading osgb files building static libraries

[Jordi Torres]

Hi Robert et al,

Just to add/emphasize some points on Rafa's submission:

The general cmake code becomes cleaner, putting all the Android stuff in
the toolchain let us to maintain it better. Also we could add different
toolchains for different Android versions.
Maybe be this approach could be used too for other platforms, like MacOSX
or iOS, not having to tweak CMake stuff each time a new OSX/IOS version is
released (we could add a new toolchain). Also it would make thinner the
current CMake code (that is a already a little monster, you know).

Other point is that having the OSG libraries in android as dynamic could
reduce quite a lot the size of the final app, which is a good thing.

It would be great if somebody could test this submission.

Cheers.


2014-11-13 8:45 GMT+01:00 Rafa Gaitan rafa.gai...@gmail.com:

 Hi Robert,

 I finally had some time to change the build system for Android using a
 Toolchain, which, I think, will be easier to maintain and uses cmake
 standard system to build it.

 My changes:
 ---
 - I changed the cmake files and added a toolchain for building OSG in
 Android. The toolchain is based on the one used at OpenCV. For building OSG
 for android you just need to do:

 mkdir build_android_static_gles2  cd build_android_static_gles2
 cmake .. -DANDROID_NDK=path-to-the-android-ndk

 -DCMAKE_TOOLCHAIN_FILE=../PlatformSpecifics/Android/android.toolchain.cmake

   -DOPENGL_PROFILE=GLES2
   -DDYNAMIC_OPENTHREADS=OFF
   -DDYNAMIC_OPENSCENEGRAPH=OFF
   -DANDROID_NATIVE_API_LEVEL=15 # optional
   -DANDROID_ABI=armeabim #optional
   -DCMAKE_INSTALL_PREFIX=path-to-the-install-path
 #optional
 make -j 8
 make install

 The OPENGL_PROFILE works as expected, changing it to GLES1 it builds
 and links OSG using GLES1.
 The DYNAMIC_OPENTHREADS/DYNAMIC_OPENSCENEGRAPH parameters also allows
 to build the dynamic libraries

 - I also added some build fixes for android related to the texture formats
 and added some missing USE_OSG_SERIALIZER_WRAPPER in the osg serializer
 library to support loading osgb files in static.
 ---

 I haven't updated the android examples yet, I've been using osgAndroid
 library which I'm also adding support to GLES2 to test it. I will send the
 modified examples as soon as possible.

 I hope everyone finds this useful!

 Regards,
 Rafa.

You can retrieve the intersection point/points, center, distance, etc. from

Re: [osg-users] minor issues getting started

[Jordi Torres]

Hi Daniel,

2014-10-14 2:50 GMT+02:00 Daniel Herring dherr...@tentpost.com:

 Hi all,

 I'm just getting started with OSG.  Here are a couple things that tripped
 me up.  They should be easy to fix.


 Some of the examples are missing files needed to run correctly.  This
 includes osgshaders and osgviewerQt.  The missing files are not included in
 the release zip file.  They can be found in OpenSceneGraph-Data.


This is intended, the OpenSceneGraph-Data has its own svn repository. You
should set the OSG_FILE_PATH environment variable pointing to your
OpenSceneGraph-Data folder.
See :
http://www.openscenegraph.org/index.php/documentation/getting-started
http://www.openscenegraph.org/index.php/documentation/guides/user-guides/113-running-the-examples




 The Trac Wiki page on SVN is outdated.
 http://trac.openscenegraph.org/projects/osg/wiki/Downloads/SVN


The trac is online only for historical/backup purposes, it does not make
sense to update the trac. Probably some advice in the trac front page
stating that the information contained in it might be outdated could be
good.




 The correct URLs are on this page.
 http://www.openscenegraph.org/index.php/download-section/
 code-repositories/30-subversion


 Also, I suspect the main Trac page should redirect to the main OSG page,
 not its own (outdated) page.

 http://trac.openscenegraph.org/
 http://trac.openscenegraph.org/projects/osg/  -- seems outdated
 http://www.openscenegraph.org/  -- seems current


The openscenegraph.org is the main osg website, and it includes a link to
the old trac in the documentation section. Not sure if it makes sense to
redirect the trac to the main website.

Anyway thanks for the comments.

Cheers.




 Later,
 Daniel

Re: [osg-users] OpenVRML plug-in HOWTO

[Jordi Torres]

 the OpenVRML plug-in:
 - OPENVRML_INCLUDE_DIR: C:/OpenSceneGraph/3rdParty/openvrml;
 - OPENVRML_LIBRARY: C:/OpenSceneGraph/3rdParty/lib/openvrml.lib;
 I didn't use OpenVRML Debug library in the end (see Notice below) so
 OPENVRML_LIBRARY_DEBUG was not set.

 Now, for runtime, OpenVRML requires some environment variables and
 data or the OpenVRML plug-in won't work at all:
 - Copy the resulting openvrml.dll DLL from
 C:\openvrml-0.18.9\{Win32|x64}\{Debug|Release}\bin to e.g.
 %OSG_ROOT%\bin; I'm assuming here that %OSG_ROOT%\bin is in your PATH;
 - Copy the resulting DLL nodes from
 C:\openvrml-0.18.9\{Win32|x64}\{Debug|Release}\bin\node to e.g.
 %OSG_ROOT%\share\OpenVRML\bin\node and add OPENVRML_NODE_PATH
 environment variable to point to this folder;
 - Copy the C:\openvrml-0.18.9\data folder to e.g.
 %OSG_ROOT%\share\OpenVRML and add OPENVRML_DATADIR environment
 variable to point to %OSG_ROOT%\share\OpenVRML\data.

 Optionally, you can enable scripting, compiling the javascript DLL
 project. To this end, you'll also need XULRunner SDK 12.0 available
 only for Win32 target, not x64 one. So I quickly gave up on this one
 as I moreover wasn't able to run OpenVRML examples with scripting
 (e.g. rotationToy.wrl, Click.wrl) without crashing OpenVRML (using a
 Win32 build of course). Nevertheless, don't forget to copy the
 resulting javascript.dll from
 C:\openvrml-0.18.9\{Win32|x64}\{Debug|Release}\bin\script to e.g.
 %OSG_ROOT%\share\OpenVRML\bin\script and add OPENVRML_SCRIPT_PATH
 environment variable to point to this folder if you want to play with
 scripting.

 In some debugging scenario (e.g. VRML file displayed differently in
 sdl-viewer and osgviewer, like OpenVRML's snoman.wrl example where the
 arms are missing in osgviewer), it might be helpful to also build
 OpenVRML's SDL-based viewer sdl-viewer. For this, you'll need SDL
 1.2.x. I've successfully built sdl-viewer with SDL 1.2.15.

 Notice: DON'T MIX Debug and Release versions of sdl-viewer.exe,
 openvrml.dll, javascript.dll and the DLL nodes in the same folders:
 even if they're named differently (e.g. with d suffix for Debug
 version), OpenVRML will badly crash as it seems to try to use/load
 both flavours!

 For interested people, I've created from scratch native VS 2010
 solution/projects files using property sheets for the external
 dependencies. Just drop me a mail and I'll send you. I'll also submit
 them to the OpenVRML authors/maintainers.

 Cheers,

  Émeric

  Hi,
 
  For those lost souls trying to build the OpenVRML plug-in on Windows,
  here's how I did it with OSG 3.2.1. Hope this helps, as I was
  desperately looking for such informations the passed days ;-)
 
  First, the informations at [1] are completely outdated. By contrast to
  what's stated there, OpenVRML 0.14.x is no more relevant at all, even
  on Windows. OpenVRML 0.18.x is the way to go. So, to build the
  OpenVRML plug-in, you need to build OpenVRML first. For this, the
  Boost C++ Libraries are required. And OpenVRML's default build
  configuration also has dependencies on libpng and FreeType.
 
  I've successfully built OpenVRML 0.18.9 against Boost 1.55.0, libpng
  1.6.13 and FreeType 2.5.0 on a Windows XP x64 PC using the Visual
  Studio 2010 Professional IDE. I'm assuming here (i) that your OSG root
  _build_ folder is C:\OpenSceneGraph and (ii) that you've correctly set
  up and/or built Boost, libpng and FreeType. Here are the steps:
  - Download OpenVRML 0.18.9 source code openvrml-0.18.9.tar.gz from
  http://sourceforge.net/projects/openvrml/files/openvrml/0.18.9/;
  - Extract openvrml-0.18.9.tar.gz somewhere; say in C:\openvrml-0.18.9
  folder;
  - Get the following missing project files from
  https://svn.code.sf.net/p/openvrml/code/tags/0.18.9/ and copy them to:
- src/local/libopenvrml-dl/openvrml-dl.vcxproj:
  C:\openvrml-0.18.9/src/local/libopenvrml-dl/openvrml-dl.vcxproj;
- src/node/x3d-interpolation/x3d-interpolation.vcxproj:
  C:\openvrml-0.18.9/src/node/x3d-interpolation/x3d-interpolation.vcxproj;
- src/script/javascript.vcxproj:
  C:\openvrml-0.18.9/src/script/javascript.vcxproj;
  - Remove any entry PlatformToolsetWindows7.1SDK/PlatformToolset
  from the project files;
  - Remove any entry IncludePath
 
 
 Condition='$(Configuration)|$(Platform)'=='{Debug|Release}|x64'C:\Boost\include\boost-1_43;$(IncludePath)/IncludePath
  from the project files;
  - Fix the x64 platform settings of all projects files, copying from
  the Win32 section. Most were incorrectly created as Applications
  rather than DLLs!
  - Go to C:\openvrml-0.18.9 and open OpenVRML.sln solution;
  - Add $(BOOST_ROOT) to additional include directories of all projects;
  - Add $(BOOST_ROOT)\lib{32|64}-msvc-10.0 to additional library
  directories of all projects;
  - Add /bigobj compiler option to Debug|x64 configuration of openvrml
  DLL project to work around fatal error C1128;
  - Ensure that input libraries of openvrml DLL project is set to
  shlwapi.lib;XmlLite.lib;%(AdditionalDependencies) for all
  targets/platforms;
  - Ensure that input libraries of vrml97 DLL project is set to
  libpng16[d].lib;freetype250[_D].lib;%(AdditionalDependencies) for all
  targets/platforms and that additional library directories are properly
  set;
  - Build the vrml97 and x3d-* DLL projects. The openvrml DLL and
  openvrml-dl static library projects are automatically built as
  dependencies;
  - Copy the headers from C:\openvrml-0.18.9\src\libopenvrml hierarchy
  to C:\OpenSceneGraph\3rdParty\include\openvrml, replicating the
  hierarchy, as well as the resulting openvrml.lib library files to
  OpenSceneGraph\3rdParty\lib and openvrml.dll DLL files to
  OpenSceneGraph\3rdParty\bin;
  - Add OPENVRML_DIR environment variable, pointing to
  C:\OpenSceneGraph\3rdParty;
  - Update
  OpenSceneGraph\OpenSceneGraph-3.2.1\src\osgPlugins\vrml\CMakeLists.txt
  file to build against OpenVRML 0.18.x:
- add references to Boost: add ln. 1-3:
 
  FIND_PACKAGE(Boost COMPONENTS thread)
 
  INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
 
  LINK_DIRECTORIES(${Boost_LIBRARY_DIRS})
 
- remove references to antlr and regexp libraries: delete ln. 9-21
  and ln. 23-24;
- add OPENVRML_USE_DLL preprocessor definition: add ln. 31:
 
  ADD_DEFINITIONS(-DOPENVRML_USE_DLL)
 
  Final result should be:
 
  FIND_PACKAGE(Boost COMPONENTS thread)
  INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
  LINK_DIRECTORIES(${Boost_LIBRARY_DIRS})
 
  INCLUDE_DIRECTORIES(${OPENVRML_INCLUDE_DIR})
  INCLUDE_DIRECTORIES(${OPENVRML_INCLUDE_DIR}/openvrml)
 
  IF (WIN32)
  INCLUDE_DIRECTORIES(${JPEG_INCLUDE_DIR

  Hi All,

 I am with Robert on this one. It is fairly easy to add content to the
 existing website for anyone who wants to do so. Creating another
 website only because you want to use your preferred technology
 (nothing against wikis!) is not really helpful - it would only
 fragment the resources which are in short supply already.

 See the problems with the OSG forum - it has a serious shortage of
 moderators, so posts from new users don't get approved in time, spam
 gets through, etc. And someone still has to maintain it, so that it
 doesn't get hacked or broken.

 How is going a separate wiki help here? Are you willing to keep
 maintaining it long term? If yes, why not to maintain/improve the
 documentation on the OSG website? Is anything wrong with it? If yes,
 why it cannot be fixed?

To summarize - I am all out for better docs, but please lets not
 splinter the few resources we have already for the sake of reinventing
 the wheel.


That's exactly my point. I have dedicated hundreds of unpaid hours to get
the current website ( less than two years alive ) working, it has been a
tone of work migrating from the old trac: hundreds of articles, outdated
documentation, joomla template tweaking, etc. We -the community- discussed
the structure, the technology to use, less than two years ago. I did it
happy to be contributing to the OSG community.

Maybe the result is not the best for all the people. And for sure it can be
improved. But first try to improve that we already have, before reinventing
the wheel.

What I had to remark with my first mail was the fact that adding
documentation to the website is quite easy, or at least that's my point of
view. A wiki won't make a difference, you should ask for permissions and
then edit some page, or do some new page. I didn't want to sound rude so my
answer was something like: go and hit to the wall yourself, I'm not gonna
do it twice, if you come with something better it will be ok.


Thanks.



 All the best,

 Jan

Re: [osg-users] create a OSG wiki: (it was OpenSceneGraph Oculus Rift integration )

[Jordi Torres]

OFF TOPIC :)

By the way, the tutorials section is needing some love from the community.
The tutorials in the old trac were not compiling anymore ( they were in
OSG-1.x though), if somebody wants to post some it would be nice.

Thanks

 I am with Robert on this one. It is fairly easy to add content to the
 existing website for anyone who wants to do so. Creating another
 website only because you want to use your preferred technology
 (nothing against wikis!) is not really helpful - it would only
 fragment the resources which are in short supply already.

 See the problems with the OSG forum - it has a serious shortage of
 moderators, so posts from new users don't get approved in time, spam
 gets through, etc. And someone still has to maintain it, so that it
 doesn't get hacked or broken.

 How is going a separate wiki help here? Are you willing to keep
 maintaining it long term? If yes, why not to maintain/improve the
 documentation on the OSG website? Is anything wrong with it? If yes,
 why it cannot be fixed?

 To summarize - I am all out for better docs, but please lets not
 splinter the few resources we have already for the sake of reinventing
 the wheel.


 That's exactly my point. I have dedicated hundreds of unpaid hours to get
 the current website ( less than two years alive ) working, it has been a
 tone of work migrating from the old trac: hundreds of articles, outdated
 documentation, joomla template tweaking, etc. We -the community- discussed
 the structure, the technology to use, less than two years ago. I did it
 happy to be contributing to the OSG community.

 Maybe the result is not the best for all the people. And for sure it can
 be improved. But first try to improve that we already have, before
 reinventing the wheel.

 What I had to remark with my first mail was the fact that adding
 documentation to the website is quite easy, or at least that's my point of
 view. A wiki won't make a difference, you should ask for permissions and
 then edit some page, or do some new page. I didn't want to sound rude so my
 answer was something like: go and hit to the wall yourself, I'm not gonna
 do it twice, if you come with something better it will be ok.


 Thanks.



 All the best,

 Jan

Re: [osg-users] OpenSceneGraph Oculus Rift integration

[Jordi Torres]

Hi Bram,

What sometimes helps is a good wiki where enthusiasts/independents can
 share all the information they got on the SDK and the workings of the OR.
 Actually might be good for OSG too. Lots and lots of information and
 knowledge on the forums, but sometimes it's hard to find it.


This is off topic ( sorry about that, but I have to answer this). Anyone
can ask for access to the OSG website and post whatever OSG related
material he/she wants.

Again sorry about the off topic post.

Cheers.

[osg-users] create a OSG wiki: (it was OpenSceneGraph Oculus Rift integration )

[Jordi Torres]

Hi Bram,

If that smaller things you find do not fit in any of the OSG website
categories, I'll be happy to have a wiki to collect them. There exists
quite a lot of posts on this same topic in the OSG mailing list, so it is
not a new discussion :). At the end we chose joomla, you can follow the
discussions in the archives, but I think that decission is not written in a
stone.

The main problem of having a new wiki is the lack of community support for
this tasks, until very recently we have had lack of forum moderators (I
don't know how it is going that now, as I use the mailing list), and also
lack of help to migrate the old trac to the new Joomla instance. That's why
I always try to encourage the community members to post to the website.

I guess the wiki should have moderators aswell, to prevent from spammers
and to prevent to have erroneus information in it.

Said that, feel free to step in and build a wiki, I will be happy to post a
link in the joomla instance, and collaborate as much as I can :).

Moreover, I believe dreamhost has one-click installers for many flavours of
wikis, so if you implement something in any of the most common wiki
frameworks it shouldn't be too hard to migrate it to the OSG server.

In the meantime if you see something that could be in the OSG website and
it is not, please don't hesitate to post that.

Cheers.

cite Hopefully last post off topic: creating a good wiki with a good
basic structure that has the possibility to cover all important classes and
functions in OSG, and can be easily added to by all, is a huge difference
from giving people who ask it full access to post whatever OSG related
material he/she wants on the OSG website. In the first I would easily add
some knowledge that i found on the forum which was hard to find, but if I
want to add something to the OSG website I would have to write some kind of
guide, but that's not the right format for the smaller things that I find
out. I hope you can understand the difference I'm trying to explain.
for example: http://wiki.secondlife.com/wiki/LSL_Portal/nl - it had quite
an extended page for each function in the script language. The creators
make basic pages about the functionality, and the enthusiasts add their
specific knowledge to it, and it works really well...

Re: [osg-users] Convert depth image to 3D model

[Jordi Torres]

Hi Mikhail,

In my opinion the easiest way is to use a displacement mapping shader. In
the vertex shader you use the texture values to alter vertex positions. I
think there is an example in the OSG Cookbook from Wang Rui.

Hope it helps.


2014-07-24 12:21 GMT+02:00 Mikhail Matrosov mikhail.matro...@gmail.com:

 Hello,

 I have a depth image, i.e. grayscale floating point image, where each
 pixel represents a depth value in this point of a scene. What is the
 easiest way to create a 3D model of the scene?

 I know I can simply loop over all pixels and create a pair of triangles
 for each pixel. But I feel like it has to be more elegant solution.

 Cheers,
 Mikhail
