[osg-users] Using OSG Embedded in an Existing OpenGL Project
Hi,
Background:
I've written an application in C# for various reasons. SharpGL provided the
OpenGL portion, C# provided the Database, and Intellisense works with it in VS
2010. I've rewritten this application in 3 different frameworks and have hit
issues I could not solve for one reason or another. For example, now that my
application works and I use it everyday, I'm trying to enhance some of its
features, such as loading a 3D object and good text rendering.
I've come across OpenSceneGraph and have been trying to use it with the C#
wrappers. I couldn't get that working and read a bunch of posts providing other
solutions and mentioning it isn't supported anymore. Thus, I've learned to
write a wrapper for a C++ OSG DLL to call some native OSG functions.
It works great, except that it doesn't, LOL. The code it fine, I've tested it
in a sample, non C# application using the viewer and all.
The Question:
The part that I don't understand is how to use OSG to render in an existing
OpenGL viewport. Is there a way to attach to the existing OpenGL instead of
creating the OSG viewer as noted in every OSG example I've seen?
C# SharpGL initialization
Code:
// Initialize SharpGL
void initSharpGL() {
openGLControl = new SharpGL.OpenGLControl();
((System.ComponentModel.ISupportInitialize)(openGLControl)).BeginInit();
//
// openGLControl
//
openGLControl.BitDepth = 32;
openGLControl.Dock = System.Windows.Forms.DockStyle.Fill;
openGLControl.DrawFPS = true;
openGLControl.FrameRate = 60;
openGLControl.Location = new System.Drawing.Point(0, 0);
openGLControl.Name = openGLControl;
openGLControl.RenderContextType = SharpGL.RenderContextType.FBO;
openGLControl.Size = new System.Drawing.Size(1680, 1060);
openGLControl.TabIndex = 0;
openGLControl.OpenGLInitialized += new
System.EventHandler(openGLControl_OpenGLInitialized);
openGLControl.OpenGLDraw += new
System.Windows.Forms.PaintEventHandler(openGLControl_OpenGLDraw);
openGLControl.Resized += new System.EventHandler(openGLControl_Resized);
openGLControl.Click += new System.EventHandler(OpenGL_Click);
((System.ComponentModel.ISupportInitialize)(openGLControl)).EndInit();
Controls.Add(openGLControl);
...
}
Native OSG Code:
Code:
// Create the scene root
mRoot = new osg::Group;
// The viewer
mViewer = new osgViewer::Viewer;
mWindow = mViewer-setUpViewerAsEmbeddedInWindow(0, 0, 1680, 998);
mViewer-getCamera()-setClearMask(0);
mViewer-setSceneData(mRoot);
mViewer-realize();
osg::ref_ptrosg::Geode geode = new osg::Geode;
std::string fontFile(arial.ttf);
font = osgText::readFontFile(fontFile);
if (font.valid()) {
osgText::Text* text = new osgText::Text;
if (text != 0) {
text-setFont(font);
text-setColor(osg::Vec4(0.0f, 1.0f, 1.0f, 1.0f));
text-setCharacterSize(40.0f);
text-setPosition(osg::Vec3(100.0f, 100.0f, 0.0f));
text-setText(SomeSome!);
text-setLayout(osgText::Text::LEFT_TO_RIGHT);
geode-addDrawable(text);
}
}
mRoot-addChild(geode);
The OSG Draw Callback function contents
Code:
mViewer-frame();
Thank you!
Cheers,
Dainon

[osg-users] Is there something like an optimal way for integrating physics?
Hi, propably the answer depends on what is to be done with physics. (and has been discussed before?) But i'm curious if someone can post his/her experiences with OSG and physics-integrations concerning performance differences. Well, up to now i only tried PhysX ... and my answer rised because i found three ways for integrating PhysX: - callback - GUIEventAdapter - node-integration There might be more ... Finally, let me say that i wanna do something in the direction of vehicle dynamics. First using the 'pre-defined models', but afterwards maybe creating a more sophisticated model. So i'm pretty sure, that i could use any physics engine ... maybe Bullet is better to be integrated into OSG than PhysX? Or the way round? Or Havok is faster? Basically, i'm just wondering if there are 'notable' differences in performance concerning the different physics-SDKs and their ways of integration? (Especially in terms of vehicle dynamics) Thank you very much!

[osg-users] Memory leak notify handler
Hi, I'm new here, and quite new in the OSG world :) I use Visual Studio 2008 with Visual Leak Detector to dump memory leaks. I tried to rebuild an example from OpenSceneGraph Beginners Guide - page 58 to redirect the OSG notify stream as follows. Unfortunately Visual Leak Detector indicates a memory leak (new LogFileHandler...) - so I wonder if this really a leak or just a false positive? Actually I cannot see the error... osg::setNotifyLevel( osg::INFO ); osg::setNotifyHandler( new LogFileHandler(output.txt) ); -- the potential leak (Sorry I wanted to post the full code, but I get an error like you need at least 2 posts to include links/urls even if my code doesn't include any urls) Thank your very much! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=49450#49450 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgDB::readNodeFile returning null after an excessive amount of calls
Thanks for the reply, I actually figured out what the issue was over the weekend. I was hitting a hard limit, of 512, for how many I/O files can be open at the same time with stdio. I used the _setmaxstdio function to help with that, but the major problem was caused by me not closing some files that get continually reopened.

[osg-users] How to draw a simple frustum wireframe cube?
Hello Forum, I am an absolute osg-beginner. I am currently working on a very huge project which is using osg. I now would like to draw something in the existing scene without messing everything up. I will try to give you as much detail as I can to make it easier to understand. I have access to a callback-function which is called before every frame drawing. Also I have access to the two matices Code: this-rootTransform = opencover::cover-getObjectsXform()-getMatrix(); // Get camera frustum parameters osg::Matrix matProj = opencover::coVRConfig::instance()-screens[0].camera-getProjectionMatrix(); matProj.getFrustum( this-frustum.left, this-frustum.right, this-frustum.bottom, this-frustum.top, this-frustum.znear, this-frustum.zfar ); As you probably see the call opencover::coVRConfig::instance() also returns the instance. What I would like to do now is draw some simple lines (as in like glBegin) but in screen coordinates, so with positions in the frustum corners like (1,1,1) or (1,-1,-1). The reason for this is that I want to make the whole frustum visible because I am using a stereoscopic VR-renderer and I want to validiate how big the frustum is and when do you step into the 3D scene. I hope anyone can help me with this and can provide some simple sample code. If you need more detail, feel free to ask back. Thank you!

[osg-users] osgViewer takes over my standard input
Hello, I'm trying to write a program where the renderer is running on a
separate thread. On the main thread I want to control the command line inputs
but as soon as I add scenedata to the osgViewer which is stored in the renderer
then the renderer takes over the standard input. std::cin in the main thread is
ignored. If I put std::cin in the renderer thread however the program pauses
and expects an input from the command line.
Does anyone know how I can prevent osgViewer from taking over the command line?
I have attached sample code to this post where I demonstrate the problem.
Code:

[osg-users] Opinions: is OpenSceneGraph the right choice?
Hi, I've been programming in OpenGL for several years now, and I'm about to start a new project and thought OpenSG might be a good tool to use. However, I'm integrating data from lots of outside sources (gyros, cameras, network, etc) so I can't just do a Viewer run() (looking at doing the Viewer frame() thing), but I'm also going to have lots of frequently changing geometry camera information. All the demos I see simply construct a Scenegraph once at program start, then do Viewer run(). Is it possible/advisable to have frequently changing scenegraphs with OpenSG (eg, new nodes, dying nodes, changing nodes, etc). ... Thank you!

[osg-users] Multi-rendering per frame
Hi, I have three pre-rendered render-to-texture cameras using frame-buffer-object to generate a final texture for me at each frame. It works fine, but now I want them to do the generation multiple times per frame, can you give me some hints? I've tired the following methods but none of them works: 1. To allow the group of cameras have multiple parents which belong to the same root, so that the group of camera can be reused, but I'm afraid the calculation of different path may be carried out simultaneously. Anyway, the results is not as expected. 2. To use osg::Sequence to group these cameras and setup it like this: Code: seq-setInterval(osg::Sequence::LOOP, 0, -1); seq-setNumRepeats(times_of_render_per_frame); This also doesn't work out. I was wondering whether it's due to the bugs in my code or simply I cannot use the osg in such a way. ... Thank you!

Re: [osg-users] Memory leak notify handler
OSG uses smart pointers to manage memory (and release it if the last pointer is destroyed). The handler created with new in your cited code is stored in a smart pointer variable (see Notify.cpp) osg::ref_ptrosg::NotifyHandler _handler; (if the cast is a NotifyStreamBuffer). So I guess a memory leak could occur, if a StreamBuffer different than NotifyStreamBuffer is used. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=50090#50090 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Open GL ES 3.0
Hi everyone, the specification of Open GL ES 3.0 has been released. So I wonder if anyone is planning to integrate it into osg? As far as i know it is compatible to OpenGL ES 2.0, but there are some more features. For example would it be interesting if the new texture-compression formats (ETC2/EAC and ASTC) will be supported in future (they are also part of OpenGL 4.3). Does anyone plans something or has an idea how complex it is to do this integration? I think it shouldn't be that hard because OGL ES is getting closer to OpenGL... Thank you!

Re: [osg-users] Self-Shadowing of Billboards
Billboards present large advertisements to passing pedestrians and drivers. Today it is estimated that the average individual is bombarded with more than 5,000 advertisements every single day. With such an overabundance of advertising, people have begun to mentally tune out advertising that they consider clutter. That means that in order to get your message across to your intended audience you have to really do something to make it stand out from the competition (http://www.emeraldoutdoor.com/). Outdoor advertising reaches its audience as an element of the environment. Unlike newspaper, radio or TV, it doesn't have to be invited into the home.

[osg-users] [3rdparty] Compiling GDAL with HDF4-support
I need GDAL with both Shapefile and HDF4-Support, if possible in 64 bit. Since the normal GDAL-versions from (gisinternalscom) have Shapefile, but no HDF4 and the version from FWTools has HDF4, but no Shapefiles, Im afraid I have to compile a GDAL-version by myself. The problem is that Im 'just' a geographer with programming skills, but no real IT-expert, and Ive never compiled open source by myself, so maybe my question is quite simple for you. :) First Ive downloaded the source code from (tracosgeoorg). The I opened makegdal90.vcproj with Visual Studio 2010. It needed to do some updates, then it opened. If I compile it without changes, I get a GDAL-folder with a new GDAL19.dll. If I try to use this whole folder in my C#-project that works with normal GDAL-versions, I get a error. But if I only copy the new GDAL19.dll over the old one in the existing GDAL(32 bit)-folder it works. Is this how it should be or is something going wrong here already ? The second step is to switch to 64bit, in nmake.opt I changed the following entry: # Uncomment the following if you are building for 64-bit windows # (x64). You'll need to have PATH, INCLUDE and LIB set up for 64-bit # compiles. WIN64=YES Then I changed the setting of the VS-project to X64 and compiled again. It still works as before: I get a new GDAL19.dll that works fine in my old GDAL(64 bit)-folder. But then I cant do the third step, including HDF4. I found and changed the following section in nmake.opt: # Uncomment the following and update to enable NCSA HDF Release 4 support. HDF4_PLUGIN = NO HDF4_DIR = C:\HDF HDF4_LIB = /LIBPATH:$(HDF4_DIR)\lib Ws2_32.lib I tried it maybe 100 times, but it never worked. Sometimes I get a corrupt GDAL19.dll, sometimes I get 100 errors when compiling and sometimes I get a working GDAL19.dll without HDF4-support. I've read almost every Google-hit in English and German I found, but it never worked. One problem is that the files mentioned there do not exist in the HDF-versions Ive downloaded. I guess, this tips were for much older versions of GDAL and HDF4. So can anybody give a step by step tutorial How to compile GDAL with HDF4 for dummies ? ;) I need to know which HDF4-files I need, where to get them, and what exactly I have to write in nmake.opt. Or is there a ready to use GDAL-download with HDF4 and Shapefiles somewhere ?

(MayaImporter attachment) 2)if i load the same .dae in osgViewer i get all shapes except the Face. the Legs shape is there contrary to the 1st case.Eyeballs,teeth,tongue are there too.the only thing missing is the Face shape. (osgViewer attachment) the output in the console before osgViewer comes up,when loading textures and stuff is attachments osgViewer_output 12 I also don't get any log with warnings or errors in Maya when i try to export. as far as the 1st case goes i tried to export to dae just the Legs part and the joint chain having removed the joints from the waist up and when I made a new scene and imported the dae the Legs shape loaded fine.I suspect there is some problem between the Legs shape and all the rest. if anyone can help it would be much appreciated.i've got till the 31st to turn in the results.

I managed to get OSG compiled without issue for Android and incorporate it into my application. However, the models I would like to use are .3DS and I'm trying to get the 3ds plugin used. It was disabled in the build process, but was reenable without much issue. However, I don't know how to tie it into my application. Currently the Android toolchain builds OSG statically but when I enable debugging messages the code is still looking for .so plugins. This is also an issue for the texture files (osgdb_imageio.so). So I have two questions for possible solutions: 1) is there a way to make things that currently use plugins use statically linked code? Like an alternative registration to permanently register those plugins at init and make sure the code gets linked in? 2) if not, can anyone suggest how to make the plugins build as a .so and the core code to build as a static library (for Android). Or any other approaches you guys can suggest. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=49415#49415 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Using OSG Embedded in an Existing OpenGL Project
Hi
You could use graphics context\window created by another means (that what
osg::GraphicsWindowEmbedded does), but you still should create osgviewer and
stuff. You can check various osgviewer*** examples in osg source tree in

Hi,
Background:
I've written an application in C# for various reasons. SharpGL provided the
OpenGL portion, C# provided the Database, and Intellisense works with it in
VS 2010. I've rewritten this application in 3 different frameworks and have
hit issues I could not solve for one reason or another. For example, now that
my application works and I use it everyday, I'm trying to enhance some of its
features, such as loading a 3D object and good text rendering.
I've come across OpenSceneGraph and have been trying to use it with the C#
wrappers. I couldn't get that working and read a bunch of posts providing
other solutions and mentioning it isn't supported anymore. Thus, I've learned
to write a wrapper for a C++ OSG DLL to call some native OSG functions.
It works great, except that it doesn't, LOL. The code it fine, I've tested it
in a sample, non C# application using the viewer and all.
The Question:
The part that I don't understand is how to use OSG to render in an existing
OpenGL viewport. Is there a way to attach to the existing OpenGL instead of
creating the OSG viewer as noted in every OSG example I've seen?
C# SharpGL initialization
Code:
// Initialize SharpGL
void initSharpGL() {
openGLControl = new SharpGL.OpenGLControl();
((System.ComponentModel.ISupportInitialize)(openGLControl)).BeginInit();
//
// openGLControl
//
openGLControl.BitDepth = 32;
openGLControl.Dock = System.Windows.Forms.DockStyle.Fill;
openGLControl.DrawFPS = true;
openGLControl.FrameRate = 60;
openGLControl.Location = new System.Drawing.Point(0, 0);
openGLControl.Name = openGLControl;
openGLControl.RenderContextType = SharpGL.RenderContextType.FBO;
openGLControl.Size = new System.Drawing.Size(1680, 1060);
openGLControl.TabIndex = 0;
openGLControl.OpenGLInitialized += new
System.EventHandler(openGLControl_OpenGLInitialized);
openGLControl.OpenGLDraw += new
System.Windows.Forms.PaintEventHandler(openGLControl_OpenGLDraw);
openGLControl.Resized += new System.EventHandler(openGLControl_Resized);
openGLControl.Click += new System.EventHandler(OpenGL_Click);
((System.ComponentModel.ISupportInitialize)(openGLControl)).EndInit();
Controls.Add(openGLControl);
...
}
Native OSG Code:
Code:
// Create the scene root
mRoot = new osg::Group;
// The viewer
mViewer = new osgViewer::Viewer;
mWindow = mViewer-setUpViewerAsEmbeddedInWindow(0, 0, 1680, 998);
mViewer-getCamera()-setClearMask(0);
mViewer-setSceneData(mRoot);
mViewer-realize();
osg::ref_ptrosg::Geode geode = new osg::Geode;
std::string fontFile(arial.ttf);
font = osgText::readFontFile(fontFile);
if (font.valid()) {
osgText::Text* text = new osgText::Text;
if (text != 0) {
text-setFont(font);
text-setColor(osg::Vec4(0.0f, 1.0f, 1.0f, 1.0f));
text-setCharacterSize(40.0f);
text-setPosition(osg::Vec3(100.0f, 100.0f, 0.0f));
text-setText(SomeSome!);
text-setLayout(osgText::Text::LEFT_TO_RIGHT);
geode-addDrawable(text);
}
}
mRoot-addChild(geode);
The OSG Draw Callback function contents
Code:
mViewer-frame();
Thank you!

Re: [osg-users] Is there something like an optimal way for integrating physics?
Hi i've used bullet integrated through callbacks. works fine most of the time, but there are some problems wrt vehicle simulation (like ground should be rather fine tesselated if you use static mesh for ground and sometimes there are erroneous collisions with internal edges of ground mesh but latter can be already fixed in bullet, as i dont checked this stuff for like 2 years or so and it was known issue).

Finally, let me say that i wanna do something in the direction of vehicle dynamics. First using the 'pre-defined models', but afterwards maybe creating a more sophisticated model. So i'm pretty sure, that i could use any physics engine ... maybe Bullet is better to be integrated into OSG than PhysX? Or the way round? Or Havok is faster?

Re: [osg-users] Depth buffer questions
Hi
to compute depth from z-buffer depth you should use:
depth = -gl_ProjectionMatrix[3].z/(zb_depth * (-2.0) + 1.0 -
gl_ProjectionMatrix[2].z)
where:
gl_ProjectionMatrix[3].z = - 2*far*near / (far - near)
gl_ProjectionMatrix[2].z = - (far + near) / (far - near)
Cheers.
14.09.2012, 00:49, Andrey Shvartsman ashvarts...@dcscorp.com:
Hello,
I am trying to read real distance from a depth buffer from a scene, and I
have a couple of questions. I am using Wang Rui's code as a starting point
for working with depth buffers (specifically his code from the OpenSceneGraph
Cookbook Chapter 6, Recipe 4).
What I am trying to do is to read the distance from the depth buffer and dump
it to standard output as a start. I've attached an osg::Image to the viewer's
camera's depth buffer, and I am querying the image values during a click
event in a pick handler (the reason for the pick handler is I would like to
eventually do a comparison of the distance value I get from using an
Intersector vs the value from the depth buffer).
Code:
viewer.getCamera()-attach(osg::Camera::DEPTH_BUFFER,image);
image-allocateImage(32,32,1,GL_DEPTH_COMPONENT,GL_FLOAT);
So I am using a 32x32 image, and I am querying the image value with:
Code:
for(int k=0; k32; k++)
{
for(int l=0; l32; l++)
{
z_buffer=((float*)image-data(k,l))[0];
z=-1/(z_buffer-1);
std::cout z ;
}
std::coutstd::endl;
}
I understand that the z-buffer distance is not linear, so following the
article Love your Z-Buffer by Steve Baker (can't post links yet because I
don't have enough posts) I came up with the formula z=-1/(z_buffer-1) for
converting a z_buffer value to an approximate real distance value for a 24
bit depth buffer, with zNear at 1m, and zFar at 10,000m
However the values I am getting when querying the resulting image don't make
a lot of sense to me. When I am standing on my terrain in first-person mode,
visually I see the top half of my screen filled with the sky, and the bottom
half with the terrain, so I would expect to have very large distance values
for the top portion of the depth buffer image, and smaller and smaller values
as I get closer to the bottom. However all of the values in the 32x32 depth
image are around 2m.
I would really appreciate it if someone could take a look at the code and let
me know where I am going wrong.
Eventually, I would like to render the depth buffer as a grayscale image akin
to what you would see from a ranging sensor such as a lidar or a Kinect. Is
this even a good approach to do this kind of visualization or am I better of
trying some sort of a ray-tracing solution? My only concern with ray-tracing
is that I need to maintain soft real-time performance, and I am not sure
that I can achieve that using a ray-tracing solution. I would appreciate any
advise.
Thank you!
Andrey

Re: [osg-users] Opinions: is OpenSceneGraph the right choice?
Hi Randall, Randall Hand writes: Hi, I've been programming in OpenGL for several years now, and I'm about to start a new project and thought OpenSG might be a good tool to use. Be careful, OpenSG is a different project than OpenSceneGraph. However, I'm integrating data from lots of outside sources (gyros, cameras, network, etc) so I can't just do a Viewer run() (looking at doing the Viewer frame() thing), but I'm also going to have lots of frequently changing geometry camera information. All the demos I see simply construct a Scenegraph once at program start, then do Viewer run(). Is it possible/advisable to have frequently changing scenegraphs with OpenSG (eg, new nodes, dying nodes, changing nodes, etc). Yes, you can make your own loop through frame(). An example can be found at src/ViewerBase.cpp implementation of the run() method. You can change your graph between frame() calls, or use node callbacks for the same purpose. Just remember to mark changing nodes as DYNAMIC with setDataVariance() in order for the OSG threads not modifying/reading those nodes simultaneously. -- Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Qt and OpenThreads
Hi,
OpenGL rendering with Qt is kind of tricky. Qt wants to render from the
main thread, while OSG performs much better with threading enabled. We have
a working application with OSG 3.0.1, but it doesn't work anymore with OSG
3.1.2. I still need to investigate that. Qt also has improved OpenGL
rendering from a different thread in Qt 4.8, so that might be worth
investigating as well.
I did a google search on the topic a while ago and collected usefull
information:

Hello!
I'm stuck on one problem.
There is kind of big project, and I need to make Qt interface on it. What
I try to do is make a camera for Qt-interface element. The problem comes
with using OpenThreads: I'm trying to run OSG rendering inside new thread,
yielding to rendering of Qt element, like in osgQtBrowser example.
First, I create class to handle thread creating:
Code:
class ViewerFrameThread : public OpenThreads::Thread
{
public:
ViewerFrameThread(osgViewer::ViewerBase* viewerBase, bool
doQApplicationExit):
_viewerBase(viewerBase),
_doQApplicationExit(doQApplicationExit) {}
~ViewerFrameThread()
{
cancel();
while(isRunning())
{
OpenThreads::Thread::YieldCurrentThread();
}
}
int cancel()
{
_viewerBase-setDone(true);
return 0;
}
void run()
{
int result = _viewerBase-run();
if (_doQApplicationExit) QApplication::exit(result);
}
osg::ref_ptrosgViewer::ViewerBase _viewerBase;
bool _doQApplicationExit;
};
Then I try to run my viewer using it:
Code:
ViewerFrameThread frameThread(m_viewer.getViewerBase());
frameThread.startThread();
return QApplication::exec();
And here comes problem: if I use frameThread.startThread() like in
example, my project gives me access violation, like every try in new place.
Otherwise, if I use frameThread.run(), everything runs OK but Qt button
isnt getting rendered (just a white block in the corner of the screen)
I've tried to make a simply application with just model and Qt-button, and
everything works fine with .startThread(), as button doesnt get rendered
with .run() same as in my big project. Could not find any documentation
of OpenThreads. :(
So the question is, like: is it possible to render Qt thingy with
.run(), or what can possibly cause Access Violation with .startThread()?
I'm sorry if the explanation wasnt very clear, though hopefully someone
can help :)
Thanks in advance!
Cheers,
Max

Hi Harry, The OSG by default is built around rendering to one FBO onces per frame, I'd recommend not trying to get too clever with trying to reuse FBO's within one frame. Robert.

Re: [osg-users] osgViewer takes over my standard input
Hi Christoffer,
The OSG does absolutely nothing with standard input, go have a look at
the whole source code base. standard error and standard output are
used for debug and info messages but nothing is read.
So... this has to be a non OSG specific programming question, which I
suspect is likely to be down to a platform oddity on the platform you
are using.
Using standard input is a bit unusual for a rendering application,
might I suggest you just read the keyboard input from the actual
rendering window itself?
Robert.

Re: [osg-users] Open GL ES 3.0
Hi Katja, I don't personally have any work plans for adding support for OpenGL ES 3.0 but as you suggest this shouldn't be a difficult addition for others to roll their sleeves up and add as the OSG is written around coping with multiple version of OpenGL already so one would just use the same extension scheme.

Wow, it's been quite a while since anyone got confused between OpenSG

As to answer your question, how to you modify OSG objects... well most
OSG application need to do just what you are doing, and either use
update, event, cull or draw callbacks, or add event handlers and
camera manipulators to the viewer, or simply provide updates via the
the viewer main loop. The examples mostly use Viewer::run() but not
all, and Viewer::run() is really just a convenience method for writing
simply applications. If you have a look at the actual Viewer::run()
implementation found in OpenSceneGraph/src/osgViewer/Viewer.cpp you'll
see a slightly more complicated version of:
viewer.realize();
while(!viewer.done())
{
viewer.advance();
viewer.eventTraversal();
viewer.updateTraversal();
viewer.renderingTraversals();
}
You splice your own code in your frame loop. You can even subclass
from Viewer/CompositeViewer and override all of these
eventTraversal(), updateTraversal() and renderingTraversals() methods.
In short there are dozens of different ways you can update you scene
graph, what is most appropriate will depend entirely down to your
applications needs.

Re: [osg-users] Is there something like an optimal way for integrating physics?
My experience has been with Bullet, and if you've done any archive searches, then I'm sure you've came across osgBullet (osgbullet.googlecode.com). If you're concerned with performance, you should note that osgBullet supports running the physics simulation in a separate thread. You are asking a lot about optimal ways of doing the integration. It's difficult for me to compare osgBullet's approach to what you have done, as I am not familiar with your code. But I can describe osgBullet's approach: Bullet provides a btMotionState class, and osgBullet provides a derivation of that called MotionState that has a Transform member variable. During update, when the app steps the physics simulation, Bullet calls into the MotionState objects, which in turn updates the scene graph Transform nodes. Or, when running the physics simulation in a separate thread, the new Transform data is stored in an efficient triple buffer mechanism, then loaded into the scene graph during the update traversal. In osgBullet, no callbacks or custom Node types are required. I hope this info is helpful. If you'd like to discuss osgBullet further, it has its own Google Group mailing list, and the source code Doxygen documentation is fairly complete and informative. -Paul On 9/15/2012 3:16 AM, funk menera wrote: Hi, propably the answer depends on what is to be done with physics.

Re: [osg-users] Rendering issues with `osgVolume::RayTracedTechnique`?

I previously worked with an ATI card under Linux with osgVolume and didn't have problems so perhaps there has been a regression on the driver front.

I have this working in osgPPU, but I think you already have enough to do it here, I just couldn't put the pieces together. :) ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Using OSG Embedded in an Existing OpenGL Project
To render OSG in an existing OGL viewport, you still need to create an OSG viewer because that is what kicks off the OSG traversals when the frame() method is called. You also need to manage (i.e. Push and Pop) OGL state correctly since OSG and OGL share the same render context so that you don't trash your existing OGL rendering state. Anyway, here's basically what you do to setup and render OSG stuff in an OGL viewport/window. This uses CompositeViewer so you could render multiple OSG viewports embedded inside an OGL window...:) osgViewer::CompositeViewer *viewer = new osgViewer::CompositeViewer(); osgViewer::GraphicsWindowEmbedded *gw = new osgViewer::GraphicsWindow(ogl_x, ogl_y, ogl_w, ogl_h); osgViewer::View *view = new osgViewer::View; view-getCamera-setGraphicsContext(gw); view-getCamera-setViewport(osg_x, osg_y, osg_w, osg_h); // somewhere inside OGL viewport/window that has origin in LL corner . . // set rest of the view OSG camera state and matrices as usual . . view-setSceneData(scenegraph); viewer-addView(view); viewer-realize(); . . // do this during rendering loop for each OGL frame... PushOGLState(); viewer-frame(); // render OSG embedded viewport in OGL window PopOGLState(); Hope this helps...

[osg-users] OpenGL context and wglGetProcAddress
Hello. I am trying to use an external widget library in osg. This library tries to load the opengl functions during initialization using wglGetProcAddress. This procedure works in opengl but not in open scene graph. It fails for functions in gl 1.2 and later. I found this: The Microsoft Windows DLL opengl32.dll only directly exposes *OpenGL 1.1* functions. To gain access to functions from higher GL versions, you must load these function pointers manually with wglGetProcAddress. So the library cant load the functions using wglGetProcAddress. Is there any reason for that happening ? Thank you for your time. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Using a texture channel outside of OSG
Hi All
So I'm using an extension on iOS that allows me to fast draw video frames
coming from the camera in OpenGL.
The requirement though is that I bind and create the texture during a callback
so I have to call makeCurrent on the osg context then do manual OpenGL
commands, like below.
Code:
_viewer-getCamera()-getGraphicsContext()-makeCurrent();
[self cleanUpTextures];
// CVOpenGLESTextureCacheCreateTextureFromImage will create GLES texture
// optimally from CVImageBufferRef.
glActiveTexture(GL_TEXTURE5);
err = CVOpenGLESTextureCacheCreateTextureFromImage(kCFAllocatorDefault,
_videoTextureCache,
pixelBuffer,
NULL,
GL_TEXTURE_2D,
GL_RGBA,
width,
height,
GL_BGRA,
GL_UNSIGNED_BYTE,
0,
_lumaTexture);
if (err)
{
NSLog(@Error at CVOpenGLESTextureCacheCreateTextureFromImage %d, err);
}
glBindTexture(CVOpenGLESTextureGetTarget(_lumaTexture),
CVOpenGLESTextureGetName(_lumaTexture));
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
I then use a uniform to tell osg where to look for the texture, in this case
channel 5 and everything works fine. The problems start when I introduce models
loaded and rendered with osg. All the models only use textures in channel 0,
but as soon as I start using them the video quad goes black and other textures
start flickering.
My guess is osg is is doing something to my texture, is there a way to tell osg
to leave a certain channel alone, or some other sort of magic?
Thanks
Tom

Re: [osg-users] Using a texture channel outside of OSG
Hi
you should let osg know of what are you doing with opengl state, or revert it
back when done drawing your texture.
f.e. if osg thinks that active texture unit is 0, and it actually 5 after your
gl stuff bad things can happed, as next osg call to glBindTexture will leave
texture unit 0 without texture assigned, and it will sit unused in slot 5.
if you can use osg state in place where you call gl functions, i can suggest
you to use osg state setActiveTexture(...) instead of glActiveTexture calls,
and set active texture back (you can get current with osg state
getActiveTexture()) after you finished with your texture.
if not - you can try just call glActiveTexture(GL_TEXTURE0); after you are done.
Cheers.

Re: [osg-users] Using a texture channel outside of OSG
Thanks for that calling glActiveTexture(GL_TEXTURE0); at the end has worked, I'll try a more elegant solution later, but at least this has proved it can work. Pretty obvious solution, think I'd just been working on it too long.

Re: [osg-users] Using OSG Embedded in an Existing OpenGL Project
Hi So I've done this when working with the QCAR sdk as it seems to insist on having ownership of the GL Context. What you want is first setup the emmbeded viewer Code: osg::ref_ptrosgViewer::Viewer viewer = new osgViewer::Viewer(); osg::ref_ptrosgViewer::GraphicsWindowEmbedded embeddedWindow embeddedWindow = viewer-setUpViewerAsEmbeddedInWindow(0, 0, w,h); osg::ref_ptrosg::StateSet m_lastStateSet = new osg::StateSet(); viewer-getCamera()-getGraphicsContext()-getState()-captureCurrentState(*m_lastStateSet.get()); Then in your OpenGL apps render function after you have done your raw OpenGL stuff you want something like osg::State *osgState = _viewer-getCamera()-getGraphicsContext()-getState(); osgState-reset(); osgState-apply(m_lastStateSet.get()); //render your osg frame here viewer-frame(); //now get the state so you can restore next frame viewer-getCamera()-getGraphicsContext()-getState()-captureCurrentState(*m_lastStateSet.get()); Hope that helps Tom -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=50167#50167 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
