Hello Andrea,10:39, 5 September 2018 г., Andrea Martini :Dear all,i would like to enable Qt5 form Cmake(GUI) 3.8.2 using OSG 3.5.3 on Windows10. I installed QT 5.8.0 in c:\QT\... and i set environment variable QTDIR to C:\Qt\Qt5.8.0\5.8\msvc2013_64My focus consits in get osgQtBrowser and osgQtWidgets example projects in osg solutions (visual studio 2013).What i get is:Ungrouped Entries-> Qt5Widgets_DIR =  Qt5Widgets_DIR-NOTFOUNDFurthermore, several QT -> items are automatically filled with NOFOUND (after Configure process). I must manually fill each items!!!Is there a way to tell CMAKE to fill all qt entries automatically?Thank you in advanceRegardsAndrea... Thank you!Cheers,AndreaJust add C:\Qt\Qt5.8.0\5.8\msvc2013_64 to CMAKE_PREFIX_PATH variable.___

Re: [osg-users] [EXTERNAL] Re: Is there a binary distribution available for version 3.4.0?

[Konstantin Podsvirov]

Hello all!Your can try DaD's Project installers:https://dad.podsvirov.pro/houseOSG and other binaries for MSVC 2013 available.Also lookup Microsoft's vcpkg project (MSVC 2015 and later).5:00, 6 October 2017 г., Brian Davis :







Our timeframe is actually pretty urgent.  We are trying to get some software through a scanning tool for export/IP compliance.  It would be easier for us to add
 an existing distribution to the cloud scanning tool, rather than our own build.
 
I’ll reach out internally to understand their definition of publicly maintained as well.  One available from openscenegraph.org would certainly meet that criteria,
 but I’m not sure when we go outside of that.
 
Many thanks for the responses,

Brian

Hi Brian, we had one for a while, but the system hasn't been updated recently because one of our developers who maintained it is working elsewhere at this time. So, we don't have a 3.4 build.


 


I can look into reviving it at some point -- how urgent is your timeframe?

Hi Brian,

I'm not sure what your definition of publicly maintained is but my company is providing Windows builds of OSG 3.4.0 at

http://objexx.com/OpenSceneGraph.html. We set up an automated build system because we need these binaries ourselves and we found no other source for recent releases.

We are willing to entertain requests for additional 3rd party libraries and for builds of development releases. We will be posting 3.4.1 binaries within the next couple of weeks (waiting for Qt 5.9.2 or 5.10) and we could also post 3.4.0 builds with up-to-date
 3rd party library versions.

If you have any questions about our builds just let me know.

Regards,
Stuart

For purposes of IP compliance scans of our software, use of a publicly maintained binary distribution
 works better than building it ourselves.  We currently have binaries that we have built, but are interested in using a public binary distribution if available.

Brian

Re: [osg-users] Please test OpenSceneGraph master in prep for 3.5.6 dev release

[Konstantin]

Hello, Robert!

First... Thanks :)
I've compiled 3.5.6 with GL3 core on Macmini (OpenGL 3.3) with no problems.

BUT.
I have application based on OpenSceneGraph 3.4.0 (built with GL3 profile)
and it works well on Mac (in OpenGL 2.1 compatibility context)

When I've switched to 3.5.6 (GL3 core) I have multiple problems:

(*) Multiple VAO errors in console (OSG_NOTIFY_LEVEL=DEBUG_FP) when
*ShaderComposition* is ON (like vao not binded, so Program compilation was
failed).
(*) Strange things with lighting: Don't know how to explain it now, but
like something was changed in the osgUtil::PositionalStateContainer.
(*) Problems with osgAnimation::RigGeometry (I think because of VAO)
(*) osgText::Text3D setCharacterSize  don't change geometry in dynamic
(I've added handler to osgtext3d example, changed text3d node's
DataVariance to DYNAMIC and test some functions)


PS
ShaderHint=SHADER_NONE in DisplaySettings
My ShaderComposer can create version #150

Re: [osg-users] Qt3D 2.0 vs OSG

[konstantin]

Andrew, thanks for your answer.19:10, 26 october 2016 г., Andrew Cunningham :We are using Visual Studio 2013 but will be moving to Visual Studio 2015 for this project.QT3D 2.0 is a real scene graph now - it's only real advantage over OSG is that getting started with it is 'low friction' vs OSG which seems at first glance a bit overwhelming, including the whole build process, especially those pesky third-party libs. And the OSG/QT5 integration has not been always so perfect.For a large and complex project requires an appropriate environment.Boring work on building packages should deal with people who are interested.Others have to deal with creativity on the basis of pre-built dependencies.You have had the opportunity to familiarize with my project and installers I gave?I think about the creation of environment for MSVC2015, but I do this in the spare time and nothing I can say about the timing.

A few years ago, I experimented with Qt3D 1.0, but it functions for me then not 
enough.
I went to OSG and am using it now. The OSG project is developing for many years 
and he has a lot of possibilities.
Qt3D 2.0 is very much changed, but I don't use it actively.

Which compiler for Windows do you use?

Versions of the libraries that you specified match the environment I use.

You can try it now for MSVC2013 Windows:

http://download.podsvirov.pro/installers/dad-0.3.1-windows-vc12x86-testing.exe

I'm sorry - I didn't have time for extended response (I was on the transport 
and wrote a telephone).

On the website (http://dad.podsvirov.pro) you can find much more than just a 
3th party for OpenSceneGraph.
You can even find there the OpenSceneGraph binaries, which is built on the 
basis of:
- curl;
- freetype;
- jpeg;
- zlib;
- libpng;
- libtiff;
- libxml2;
- qt.

It's a development platform, created under the modular principle. You can use 
only the modules you need.
You will need:
- Download and run the appropriate installer;
- Choose the desired module (library);
- To complete the installation.

That's all - now you have a pre-built dependencies for your project.

For example, compare page "Namespaces" - terrible formatting. It's flowers.

The worst thing I saw: the description is missing some classes. For example

Chris, I know you have already build OSG dependencies for Windows.
My first experience OSG was associated with the visit alphapixel.com and it 
helped me a lot.
But OSG is very large and not always specific binaries include the desired 
functionality.
Then I realized that I needed to learn how to build OSG itself.
It was many years ago. I used dependency with alphapixel.com.
Thank you for the good work and help.

It is interesting how the process of building the dependencies?
You talk about build automation. Interesting details.

I don't think this is a good solution. But for a specific project can work.

As here it became clear that problems arise only on Windows.
My opinion is that this is due to the fact that for the MSVC compiler do not 
have a systematic approach 
when people talk about challenging projects, many module. But this is my 
personal opinion.

For Windows there is Linux (UNIX) is similar to solutions with a systematic 
approach.
For example:

MSYS2
http://msys2.github.io/

Cygwin
http://cygwin.org/

With these projects you can use OSG.
Used the GCC compiler.

Many good open and free project that uses OSG is needed not only for him.
The successful development of various Linux distributions confirms this.

I'm developing a solution which I called "Dad's House":
http://dad.podsvirov.pro

I already have a working version for MSVC2013 32-bit and 64-bit. Now you can try
OSG and not only.
The project is being established as a cross-platform and there are all the 
tools.
But since there is an acute shortage of binaries for MSVC - I started here.
I have the current version, as well as frozen status for 2014 and 2015.

Now I have automated many issues, but still a lot need to improve.

If you have additional ideas, I encourage them to share on the mailing lists.

Again Chris. You can download the installers here:

http://dad.podsvirov.pro/house/installers

Deflate the available modules and Repack the archive. But I can't promise that 
I now have all the dependencies.
I am developing a project in their spare time. Specific request can be faster.

(sorry for possible mistakes in text)

[osg-users] Windows binaries

[Konstantin Podsvirov]

Hello dear OpenSceneGraph users and fans of Windows!

Podsvirov my name is Konstantin and I'm a user like you.

I have a few options precompiled
versions for Windows MSVC2013 (now, but the list can be extended).

Here is a list of available versions:

http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2015-December/271816.html

I already wrote about this:

http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2015-December/271816.html

I build OpenSceneGraph as part of my "Dad's Project". The binaries are available
on the website "Dad's House":

http://dad.podsvirov.pro

For Emmanuel Pot <emmanuel@bentley.com>:

Installer dad-0.3.0-windows-vc12x86-testing.exe (32 bit) built with OSG Examples
3.4.0 OSG, Qt 5.5.1 (in the folder share/OpenSceneGraph/bin).

The example osgviewerQt works for me, but it starts rendering only after a 
window resize.

But more complex applications such as osgEarth (osgeartр_qt file.earth)
work well (32 and 64 bit).

Generally, if you are interested, you can download the installers and to try.

If you have questions, ask. I'll try to answer.

(sorry for possible mistakes in text)

[osg-users] Fwd: Add info about External Project and Windows binaries

[Konstantin Podsvirov]

30.11.2015, 21:29, "Konstantin Podsvirov" <konstan...@podsvirov.pro>:

Hi! My name is Konstantin.

I have a certain interest in the project, OpenSceneGraph, and osgEarth.

I am the author of the project osgQtQuick, which is now under development. 
Basic information about the project can be found on github:

https://github.com/podsvirov/osgqtquick

I would like to add a link to the project on the website openscenegraph.org/com.
I registered on the site, but I have no rights. I need help.

Its the main time I spend on Windows and Debian.

I develop on the Windows "Dad's Project". Basic information on the website:

http://dad.podsvirov.pro

Now the project provides binaries for Windows in several versions:

http://dad.podsvirov.pro/build?module=osg

I think that these projects can be useful to the OpenSceneGraph community. And 
want to know about them.

I wrote a very brief and if you have any additional questions, write and I will 
try to answer.

(Sorry for possible mistakes, English is not my native language)

It's possible.

You can create new class AndroidCameraTexture (etc.) inherited from the
osg::Texture2D and override method apply:



*apply(osg::State state){*

*glBindTexture(GL_TEXTURE_EXTERNAL_OES, texId)*

Re: [osg-users] Fwd: Last update in the osgAnimation::Animation ONCE mode bug fix

[Konstantin]

Hi, Robert!


To see what happen, just run osganimationviewer with low FPS with patch and
without it.

*OSG_RUN_MAX_FRAME_RATE={2, 3 or 5} osganimationviewer* *--play-mode once*
some_model_with_rig.osgb

osganimationviewer's source with play-mode option in the attachment.


Without patch, the last rendered picture (with different FPS) can be not
the same.
With patch, rendered picture is always the same no matter of FPS.

 I need to test this out to check what happens right now and with your
 patch, and whether there is a CPU overhead.

 What is the easiest way to recreate the problem you've seen?  Modifying an
 OSG example would probably be the most direct way.

 Cheers,

 Hi Nick,

 The osgDB::SharedStateManager might well be what you are looking for.
 It's not something I wrote or have used so can't provide lots of details on
 how best to use it, but I can say it's role is for sharing state between an
 already loaded scene graph and new loaded scene graph.

 Sebastian's suggestion about the using the Object Cache feature of
 osgDB::Registry is useful too for sharing osg::Image, which will help the
 SharedStateManager spot places where osg::Texture can be shared when they
 use the same osg::Image.

Hi, Robert!

In dynamic OSG-3.3.6.119 everything is good, but in static build it fails
because of:

2015-03-12 21:16 GMT+04:00 Robert Osfield robert.osfi...@gmail.com:

 Hi KOS,

 I have resolved the bug in serialization of MorphGeometry and RigGeometry
 by moving the respective UpdateVertex callbacks out of the respective class
 scopes and into the osgAnimation namespace, renaming them to
 MorphGeometryCallback and RigGeometryCallback, and have implemented them in
 the serializers.  With these changes I am now able to convert files like
 the morphing.osg to .osgt and be able to load and run animations correctly.

 These changes can't fix pre-existing broken .osgt files though, as they
 have the bug effectively built into them.  These broken files will have to
 be amended by hand, to remove the problem callback reference, or recreated
 from original .osg or .ive files.

 The fixes are now checked into svn/trunk.

 Robert.

Re: [osg-users] MorphGeometry problem in the 3.3.6 devel release

osgAnimation::UpdateVertex*


2015-03-12 17:50 GMT+04:00 Robert Osfield robert.osfi...@gmail.com:

 Hi Konstantin,

 Have you spotted a why the .osg loading works, but the .osgt doesn't? I
 presume from what you've found that is a difference in the way that the
 callback is assigned.

 Robert.

 On 12 March 2015 at 13:44, Konstantin lalakos...@gmail.com wrote:

 Hi, Robert!

 I've discovered, that MorphGeometry has UpdateCallback (*in osgt*), that
 cannot be cast to MorphGeometry::UpdateVertex while running.

 Just done this for test:

 inside osgAnimation/MorphGeometry.cpp









 *void UpdateMorph::operator()(osg::Node* node, osg::NodeVisitor*
 nv){...if (morph){if
 (!dynamic_castMorphGeometry::UpdateVertex*(morph-getUpdateCallback()))
   morph-setUpdateCallback(new MorphGeometry::UpdateVertex);...}*

 and everything works.



 Callback must be set once in the MorphGeometry's constructor (first
 constructor called), i thing.







 *MorphGeometry::MorphGeometry() :...{...setUpdateCallback(new
 UpdateVertex);...}*

 Who can change this callback after MorphGeometry is constructed (while
 loading from osgt format)?

 2015-03-12 16:02 GMT+04:00 Robert Osfield robert.osfi...@gmail.com:

 Hi Konstantin,

 I have had a quick look at recreating the problem, and see the problem
 with OSG svn/trunk.

 I have done a couple of experiments to get a bit more feel for the
 nature of the bug.

   export OSG_OPTIMIZER=OFF

   // first create a local copy to work with, using the loader with the
 loader modifying a few bits of the data such as vertex indices that have
 long been deprecated
   osgconv morphing.osg local.osg

   // check to make sure nothing more is changed when load and write to
 .osg
   osgconv local.osg local_from_osg.osg

   // convert .osg to .osgt
   osgconv local.osg local_from_osg.osgt

   // onvert back from .osgt to .osg
   osgconv local_from_osg.osgt local_from_osgt.osg


 When I run osganimationviewer it is able to play the animation for all
 of the .osg files, including the one converted to .osgt and then back.  The
 local.osg and local_from_osgt.osg are also identical.

 Together this shows that all the data is being read and written to the
 .osgt files correctly, but for some reason osgAnimation NodeKit is not
 being configured in exactly the same way when loading via .osg or .osgt.
 Why this might be I can't say yet, I haven't had a chance to look at the
 loader or osgAnimation code.  (I'm not the author of osgAnimation so like
 everyone else just has to read the code and see what sense I can make from
 it.)

 I have other tasks to manage today so will need to come back to this bug
 later.  Others are welcome to pitch in and track down the bug and provide a
 fix.

 Cheers,
 Robert.

Re: [osg-users] MorphGeometry problem in the 3.3.6 devel release

[Konstantin]

Hi, Robert!

I've discovered, that MorphGeometry has UpdateCallback (*in osgt*), that
cannot be cast to MorphGeometry::UpdateVertex while running.

Just done this for test:

inside osgAnimation/MorphGeometry.cpp









*void UpdateMorph::operator()(osg::Node* node, osg::NodeVisitor* nv){...
if (morph){if
(!dynamic_castMorphGeometry::UpdateVertex*(morph-getUpdateCallback()))
  morph-setUpdateCallback(new MorphGeometry::UpdateVertex);...}*

and everything works.



Callback must be set once in the MorphGeometry's constructor (first
constructor called), i thing.







*MorphGeometry::MorphGeometry() :...{...setUpdateCallback(new
UpdateVertex);...}*

Who can change this callback after MorphGeometry is constructed (while
loading from osgt format)?

 Hi Konstantin,

 I have had a quick look at recreating the problem, and see the problem
 with OSG svn/trunk.

 I have done a couple of experiments to get a bit more feel for the nature
 of the bug.

   export OSG_OPTIMIZER=OFF

   // first create a local copy to work with, using the loader with the
 loader modifying a few bits of the data such as vertex indices that have
 long been deprecated
   osgconv morphing.osg local.osg

   // check to make sure nothing more is changed when load and write to .osg
   osgconv local.osg local_from_osg.osg

   // convert .osg to .osgt
   osgconv local.osg local_from_osg.osgt

   // onvert back from .osgt to .osg
   osgconv local_from_osg.osgt local_from_osgt.osg


 When I run osganimationviewer it is able to play the animation for all of
 the .osg files, including the one converted to .osgt and then back.  The
 local.osg and local_from_osgt.osg are also identical.

 Together this shows that all the data is being read and written to the
 .osgt files correctly, but for some reason osgAnimation NodeKit is not
 being configured in exactly the same way when loading via .osg or .osgt.
 Why this might be I can't say yet, I haven't had a chance to look at the
 loader or osgAnimation code.  (I'm not the author of osgAnimation so like
 everyone else just has to read the code and see what sense I can make from
 it.)

 I have other tasks to manage today so will need to come back to this bug
 later.  Others are welcome to pitch in and track down the bug and provide a
 fix.

 Cheers,
 Robert.

Re: [osg-users] MorphGeometry problem in the 3.3.6 devel release

[Konstantin]

*Hi, Robert!I can see the problem here, in
osgWrappers/serializers/osgAnimation/UpdateVertex.cpp:*

















*#undef OBJECT_CAST#define OBJECT_CAST dynamic_cast#include
osgAnimation/RigGeometry#include osgDB/ObjectWrapper#include
osgDB/InputStream#include
osgDB/OutputStreamREGISTER_OBJECT_WRAPPER2(osg_Drawable_UpdateCallback,
new osgAnimation::RigGeometry::UpdateVertex,
osgAnimation::RigGeometry::UpdateVertex,
osgAnimation::UpdateVertex, osg::Object
osg::UpdateCallback osgAnimation::UpdateVertex) {}#undef
OBJECT_CAST#define OBJECT_CAST static_cast*



And there is not any line like

*USE_SERIALIZER_WRAPPER(osgAnimation_UpdateVertex)*
inside *osgWrappers/serializers/osgAnimation*/*LibraryWrapper.cpp*


All that is very interesting for me :)


Maybe all this bugs have been floated up because of osg::Callback
refactoring in the 3.3 branch?

 Hi Konstantin,

 Have you spotted a why the .osg loading works, but the .osgt doesn't? I
 presume from what you've found that is a difference in the way that the
 callback is assigned.

 Robert.

[osg-users] MorphGeometry problem in the 3.3.6 devel release

[Konstantin]

Hello!

I have a problem with morph geometry after conversion to *osgb(t)*.

*# OSG_OPTIMIZER=OFF* osgconv osg-data/morphing.osg *morphing.osgb(t)*

osganimationviewer *morphing.osg* morph the face.
osganimationviewer *morphing.osgb(t)* *do not *morph the face.

What in can be?
Same operations in 3.2.1 are working!


*PS*
Changing in the morphing.osgt
UseVertexBufferObjects TRUE - FALSE
doesn't work.

 HI Konstantin,

 There isn't any mutex around the set/get of a the Camera::CullMask, but it
 is just a unsigned int so as long as the camera isn't deleted by one the
 threads all the threads we will contending over will be the value of the
 CullMask.  All the CullMask affects is the traversal - if it's wrong then
 you'd see the wrong parts of the scene graph traversed and this could be in
 an inconherent way - for instance half the cull traversal might use one
 mask and the other half use the new value that was set by the other
 thread.  This is the worst that can happen though, you won't get a crash.

 The completely safe and reasonable way to set things like the
 Camera::CullMask is in the update phase of the frame.  Cueing up Operation
 objects to do the operations on the scene graph in a thread safe container
 is one way of managing this - the Viewer has the OperationQueue for just
 this purpose - just add an operation via
 viewer.addUpdateOperation(operation) and it'll be called automatically for
 you, you just need to subclass from Operation and get it to do the dirty
 work for you.

 Robert.

Hello Trajce!!!

LightSource may be traversed after some Drawables. This may be the problem!
Try to move LightSource node upper to be traversed first.

:

 Hi Community,

 I have a scene where I use light lobes (shader based) which seam to work
 well. The lights are attached through osg::LightSource and are moved by
 osg::MatrixTransforms. All works well. Part of the scene is rendered by a
 third party rendering engine and I see the lights flicker there, this part
 is litten when I zoom in or pan, when the eye is static it does not. The
 software allows me to inject my own shaders for the lighting so I use the
 same shader that is proven to work. It is somewhat as losing or changing
 the gl_LightSource (ehm, I know I could use uniforms for this, but it is
 bit of old code) positions on the fly.

 Any clue what this zoom in flicker could be? Any idea is welcome

 Hi Konstantin,

 Thanks for the modified file, changes make sense now that I can
 graphically diff your changes against svn/trunk.  I'm ready to merge
 but don't know what name to use to provided credit when I check it in
 - for submissions I provide check ion message of the form:

 From FirstName SecondName, Content of submission

 That helps provide credit where credit is due and also enables us to
 follow up more easily in case there are regressions or we need further
 information about a bit of code.  So could you let me know what name
 you want to use and I'll get the fix checked into svn/trunk and
 OSG-3.2 branch.

 Cheers,
 Cheers,
 Robert.

[osg-users] Multiple light fix in the FBX importer:

[Konstantin]

Multiple light fix in the FBX importer:

in fbxRLight.cpp

This:
/
*osg::Light* osgLight = new osg::Light;*
osg::LightSource* osgLightSource = new osg::LightSource;

osgLightSource-setLight(osgLight);
*osgLight-setLightNum(nLightCount++);*
/

Must be this:
/
*osg::Light* osgLight = new osg::Light;*
*osgLight-setLightNum(nLightCount++);*

osg::LightSource* osgLightSource = new osg::LightSource;
osgLightSource-setLight(osgLight);
/

Other way, you will always have GL_LIGHT0, but the last (from FBX tree) 8-)
osgLightSource-setLight() should be after light was tuned in other words...

 Hi Konstantin,

 Could you post the full modified file to osg-submissions so I can
 review it, thanks.

 Robert.
