Re: [osg-users] Camera Move example
Hi Danny;
You mean it is not working or working but not as expected? I saw a problem
you multiply matrices wrong order. You always obey the TRS rule. First Scale
then Rotate and lastly Translate. But as I see you have done wrong order for
myCameraMatrix = cameraRotation * cameraTrans;
HTH.

Hi Jean-Sébastien,
Thank you for your reply i'm trying to do it by first method I implemented
some code but it looks like this code does nothing:
bool CameraMover::handle(const osgGA::GUIEventAdapter
ea,osgGA::GUIActionAdapter us)
{
osg::Matrixd myCameraMatrix;
osg::Matrixd cameraRotation;
osg::Matrixd cameraTrans;
cameraRotation.makeRotate(
osg::DegreesToRadians(0.0), osg::Vec3(0,1,0), // roll
osg::DegreesToRadians(60.0), osg::Vec3(1,0,0) , // pitch
osg::DegreesToRadians( 45.0), osg::Vec3(0,0,1) ); // heading
cameraTrans.makeTranslate( 1,5,1 );
myCameraMatrix = cameraRotation * cameraTrans;
osg::Matrixd i = myCameraMatrix.inverse(myCameraMatrix);
osgViewer::Viewer* viewer = dynamic_castosgViewer::Viewer*( us );
...
switch(ea.getKey())
{
case osgGA::GUIEventAdapter::KEY_Down:
viewer-getCamera()-setViewMatrix(i*osg::Matrix::rotate(-(osg::PI_2),1,0,0));
return false;
break;
..
}
}
int main()
{
..
viewer.addEventHandler(new CameraMover);
viewer.realize();
while( !viewer.done() )
{
viewer.frame();
}
Could you tell me please why my event is not working?
Thank you!
Cheers,
Danny

Re: [osg-users] Ask for osgviewerMFC memory consumption explanations
Hi Alex, There could be any number of reasons why this could be happening, and obviously some down to coding, however if you are using caching at all, then it maybe down to how long you've told the cache to keep the models, even when not used. I can't remember what the default is, but if set to never get rid of the models, then the only time their memory will be released is when the application shuts down - not merely closing and destroying the window. This leads on to another reason why you maybe seeing the memory usage you report in that, depending on the design of your app architecture, if you leave the management of dll's to the O.S., then dll's are only loaded on an as-required basis, and are only unloaded when the app shuts down. OSG has a number of static memory constructs singletons that are created at dll load time, and are not released until dll unload time (app shut down). One way around this is to manage the dll load and unload yourself, however this can be very tiresome ;-( I would suggest that, unless you are witnessing a continual increase in the memory allocated to your app, even when you are loading and unloading the same model, then I wouldn't be too concerned. Obviously if you are witnessing unrestricted memory consumption then something is up, but I suspect not at the OSG end. Finally, in my experience, beware of the false positive memory leaks reported by Visual Studio. Plenty of back talk on this in the archives, but suffice it to say VS unloads MFC too early in the app shut down process, which triggers a dump of unreleased memory warnings. VS crystal ball not working too well as when OSG dll's unload - usually after MFC due to VS problem with scheduling library loads/unloads - it releases its own memory. Where real leaks actually exist, more often than not it can be traced back to app coding errors, or inappropriate use of non ref_ptr references to scenegraph entries. I've wasted days in the past on this. You can decrease some of the false positives by forcing the load of the OSG dll's yourself, but sometimes life is just too short to be bothered ! Hope this helps. Kind regards Neil.

Why osgviewerMFC.exe use much memory after opening and closing a model than before doing nothing ??

[osg-users] infitec stereo
Hi, Last weekend I had the pleasure of seeing Ice Age 3 in 3D. I highly recommend it not only for the animated hoot but the stereo effect is definitely the most comfortable I have seen in a cinema. I'm wondering if anyone knows much about the method? Has quite a few pluses to it. It's pretty much done with wheels and filters in the cinema but it strikes me that unless its protected with patents, might be an attractive method, with a bit of work, for commodity (non quad buffering) graphics.

Re: [osg-users] [osgPlugins] Plugin Logo bug
Hi Robert,
I found an other bug with the logo plugin when using shadows (PSSM + OSG
latest svn). When shadows are used there is 2 calls from :
virtual bool cull(osg::NodeVisitor *visitor, osg::Drawable* drawable,
osg::State*) const
1 time with the default visitor and 1 time with the visitor from the shadow
implementation wich has a specific traversal mask and a specific viewport
(in my case 4096*4096) so the logo viewport is updated twice because of the
code :
if( vp-width() != logos-getViewport()-width() ||
vp-height() != logos-getViewport()-height() )
{
logos-getViewport()-setViewport( vp-x(), vp-y(), vp-width(),
vp-height() );
logos-dirtyDisplayList();
}
}
Maybe we could check the _traversalMask from the visitor before updating the
logo viewport, what do you think about ?
I know you're not a great fan from this plugin, but I find it very usefull.
Kind regards,

I've decided to merged your change rather than look for a more complex

I've tweaked your changes a little to include returning of true when
the logo is traversed on a window it's not assigned to so the logo
will get culled.

It does look like code assumes a single view per graphics window,
something that isn't always true with the OSG these days. In the
Producer days when this plugin was written one couldn't easily have
multiple views per window, but these days it's trivial and common
place thing to do. If the logo was attached in a window with multiple
views that all shared the same scene graph we'd end up with the
viewport being updated multiple times, with the last view's viewport
taking precedence.
One possible solution would be to have the callback ignore the cull
visitor's viewport and use the whole graphics windows dimensions, so
the logo would be placed relative to the window rather than the last
rendered viewport.
All in all though, putting a logo in the scene graph is not the best
way of tackling the task of adding logo's - it'd be much better to use
a slave camera attached to the viewer/viewer.
Thougts?

Re: [osg-users] [osgPlugins] Plugin Logo bug
There's something I forgot to mention :
The fix we agreed isn't working when there is more than one view with
different viewport size but sharing the same graphic context.
The context ID is equal but the viewport size is different for the 2 views,
so the logo is updated twice.
I explain my case, I'm using a composite viewer with X views sharing all
the same graphic context (saving memory) but with different sizes. And I
will use the logo plugin with this kind of configuration.
Unfortunately I don't have an ideal solution for now.

Re: [osg-users] infitec stereo
We've been using Infitec for a couple of years in our dual single-chip DLP projector VR workbench. The two filters were built-in in the two projectors (projection-design). In our experience, Infitec provides a better seperated and more stable image than active stereo or polarized stereo. You do need some color correction (and calibration) to compensate for the greenish/purplish views of the eyes. Simple color correction (e.g. in the projector color-matrix itself) is not as good as provided by the Infitec color-correction box. Also, the more recent Infitec systems (I guess this includes the stuff Dolby licenced) have better quality filters. In our case I thought the smaller glasses were cheap ~50 Eur but the bigger wide view glasses expensive ~400 Eur. http://visualisation.tudelft.nl/~michal/vr_lab/vrOpening/vrlOP974.jpg BTW. the dolby 3D wheel is inserted _inside_ the big cinema projector. I think syncing is not that much of a problem (similar to a DLP color wheel) provided you have access to the DLP sync. Dolby provides a box for this. The VR group of Bernd Frohlich in Weimar has experience with making your own mechanical filter/shutter-wheels (see publication http://www.uni-weimar.de/cms/fileadmin/medien/vr/documents/publications/IEEE-VR2005-multiviewer.pdf) Gerwin On Tue, Jul 21, 2009 at 11:27 AM, Paul Melis p...@science.uva.nl wrote: Garry Keltie wrote: Hi, Last weekend I had the pleasure of seeing Ice Age 3 in 3D.

Re: [osg-users] osgText Chopping Letters
Hi all, I share the opinion that osgText appearance is suboptimal. We've also got several complains from our Creative department on the look of the text in our engine. I confirm that the cause of the problem is as described by Mark Having written my own text renderer using OpenGL and FreeType, I can assess that this is a common problem caused by texture-based text rendering. Because of texture filtering, it is incorrect to draw the glyph geometry with the texture coordinates perfectly aligned on the glyph edges. Mark already gave the solution to this problem. I.e. The glyph geometry needs to be larger than the actual glyph so that there is an empty space around the textured glyph. Doing so allows the texture filtering to be uniform and complete all around the rendered glyph. IMHO Mark's proposed patch should be applied, as it solves one of the biggest visual problem with osgText. And from what I understand, it does not require any refactoring. I don't think that the depth write requirement is a problem in most cases (in fact, in my experience, in many contexts it is incorrect not to disable depth write or depth test when rendering text). Cheers, Tanguy PS: Using GL_NEAREST does not solve the problem unless the font size is chosen so that the glyph texels are perfectly aligned to the screen pixels. -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Mark Sciabica Sent: 17 July 2009 02:58 To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] osgText Chopping Letters Hello Mike, I was also displeased with the appearance of characters in osgText. The chopping is an artifact of texture filtering and having characters drawn on the edge of the character cell. Disabling filtering by using GL_NEAREST for MIN_FILTER and MAG_FILTER should remove the problem. (Or more accurately, will draw the character with uniformly abrupt transitions.) The problem with this is that you lose the smoothing of the text gained by the filtering. In order to draw properly filtered characters we need to draw the character cells larger than the extents of the characters to give room for drawing the intermediate blended texels. Attached is my implementation of this. This code requires that you disable depth write (or depth test) since adjacent characters will now overlap. You also need to call Font::setGlyphImageMargin(2) since the code looks at more texels around each character. The end result looks much better in my opinion. The requirement placed on the depth buffer is the reason I have not officially submitted this code for inclusion in OSG. If Robert thinks this is not too high a price for better looking text, perhaps it can be fixed so we no longer get complaints like yours.

Re: [osg-users] GPU Monitoring for OSG
Hi Nadia, What software can I use to monitor how much of the graphics card is used when I run a certain application, that uses OSF? I want to see how much my application uses the GPU In OSG you can use the stats handler (add osgViewer::StatsHandler to your viewer and press the 's' key at run time). This will give you timings for the Event, Update, Cull and Draw traversals, as well as an approximate GPU time if you have an nVidia card. ATI cards use a different extension for GPU timing and the StatsHandler was never modified to use that extension if available, so GPU timings are only visible when running on nVidia cards unfortunately. Last time I checked, there was no free tool to do what you want other than the StatsHandler. There are FPS indicators (for example, Fraps on Windows), but FPS gives you little information about what's really going on. Developers of DirectX apps can use NVPerfHUD to see lots of interesting things about their app, even do graphics profiling and identify bottlenecks (see the videos on http://developer.nvidia.com/object/nvperfhud_home.html) but for OpenGL apps, the only thing that comes close is gDEBugger (http://www.gremedy.com/) which is a good tool but it's hard to compete with NVPerfHUD, which seems more advanced and costs nothing... We use gDEBugger to profile the graphics part of our OSG apps, and it works well when you have the instrumented graphics drivers installed too. You can get lots of insight on what's going on in your pipeline, what's causing slowdowns, etc. But just to reiterate, in some cases the StatsHandler can be enough to show you the information you need. gDEBugger really lets you get into the internals of what the app is doing, but might be overkill if you just want to see how much time your app is spending in a given traversal and see if you can reduce that time.

Re: [osg-users] osgviewer stereo bug
I've started looking at code, but have no familiarity with this codebase, and time is very limited. I was wondering if someone code offer assistance on code, as in what functions to look at. I was looking at osgGA src, and found Animation path code, and in osgViewer/ViewerEventHandlers.cpp the part where it switches to animation path camera, but I'm not sure where to look to start playing around with code, since I don't know how it works yet. Just looking for additional details that help me get started on problem. Thanks. Hi Christopher, I think the problem is that fusion distance is not being calculated. Most of the manipulators calculate fusion distance using an intersection test or distance to the center of the bounding sphere of the specified node. Probably the camera manipulator to handle animations is not updating the fusiondistance so the eye separation is incorrect. A workaround could be set an EventCallback inside the root node and inside the FRAME event calculate properly the fusion distance. In an EventCallback you have the node, the Viewer and probalby all you need to compute it correctly. You can approach the fusion distance using simply a distance to the center of the bounding sphere of the node or if you want a more accurate eye separation (for example for terrains) you can calculate a test intersection. Hope this helps, Rafa.

Re: [osg-users] Frame rates vary dramatically across runs
Hi J-S and Michele, As I was summoned by shadow spell, I will drop my two cents in this discussion. Last time I checked OSG was also creating accompanying color buffer for the depth shadow map. Which usually multiplies GPU memory alocation by two (assuming RGBA is 32 bit and Z is 32 bit). Considering the fact that default multithreaded modes create double buffered SceneViews which again effectively duplicate all RTT buffers, original size requirement for shadow buffer is often 4 times more. If for example you create 4kx4k RTT shadow map - OSG will actually allocate 256 MB (!). If your app allocates aditional buffers and board has not enough memory this may be the cause of the problems. SingleThreaded mode does not utilize double buffered SceneViews so this multiplier drops to factor 2.

If you're on a Windows system, creating any viewer (osgViewer::Viewer, osgViewer::CompositeViewer with an osgViewer::View) will create one for you. GraphicsWindowWin32 is an implementation detail, because when your app runs on Linux or MacOS X you won't be able to create one, so you're better off letting OSG create the type that's appropriate to your system, which is what it will do when you use osgViewer::Viewer/CompositeViewer. Some cases might warrant creating a GraphicsWindow directly, for example if you've subclassed one of the GraphicsWindow classes to change their behavior, but that's rare. What are you trying to accomplish?

[osg-users] Stereo issues with changing viewpoint
Hi, I would like to thank Robert and everyone that has helped me so far. I have one final issue with the stereo viewing. I have a CAD assembly with a callback which changes the viewpoint for various activities. I am using the trackball manipulator to control the camera and I use the set view by matrix to set the position I want. The issue is that the separation of left and right image is too large when I move to closer viewpoints. I moved the trackball center to avoid any distance issues but that did not solve the problem. I have been struggling to find the correct approach. Does anyone have any suggestions. Thanks in advance, Christopher Back ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Frame rates vary dramatically across runs
Hi, J-S Last time I checked OSG was also creating accompanying color buffer for the depth shadow map. Which usually multiplies GPU memory alocation by two (assuming RGBA is 32 bit and Z is 32 bit). Wow, isn't that a bug? It surprises me that no one has tried to fix that, it seems pretty critical to me... I am not sure... I believe that it was impossible to use depth only FBO when they were initially introduced into OpenGL . But now it seems possible at least on NVidia's because I made such modificattion and it works ( in fact it gave me shadowing speedup improvements). But I did not try to submit this because I have not bothered to make it safe and I did not test whether mod does not break other RTT code. I may send this as is if you are interested.

Re: [osg-users] osgShadow::ShadowedScene + multiple parental node paths
Daniel, Frankly, I have never thought about such usage. I must admit that LispSM was not prepared for such scenario. All ViewDependentShadowTechniques (LispSM included) make assumption that there is one technique per View. I suppose that even if you use the same ShadowTechnique object but create two parental paths it will work like there were two independent instances rivalling for the same resources (shadow map /shadow cam view projection matrices/ texgen). So it will not work either. I am not sure if this is possible with your app but you may solve the problem by adding separate slave cameras (like HUD cams) for each extra ShadowedScene. But it will only work with extra slave or extra view. Nesting RTT camera in graph will not be enough. Each ViewDependentTechnique (and derived classes) use ptr to CullVisitor to identify View and create separate set of resources for this view. Graph nested cams use the same visitor as their parent View so it will be impossible to identify which cam is actually rendering and conflicts will be still present.

This would make text a little easier to read against distracting background imagery. Not that I know of, but you're right, it's something that I have often needed to do. The osghud example shows that it's pretty easy to do it by taking the axis-aligned bounding box of the text and making a quad of that size (of course I'd personally add a small margin all around, but that could be a parameter in the convenience function).

Re: [osg-users] Texture problems with OSG
Hi,
Thank you for the reply guys.
1)The first question I want to find a function similar to glTexImage2D in osg.
Here is some code regarding this,
[code]
/* Create checkerboard texture */
#define checkImageWidth 64
#define checkImageHeight 64
static GLubyte checkImage[checkImageHeight][checkImageWidth][4];
static GLuint texName;
void makeCheckImage(void)
{
int i, j, c;
for (i = 0; i checkImageHeight; i++) {
for (j = 0; j checkImageWidth; j++) {
c = i0x8)==0)^((j0x8))==0))*255;
checkImage[i][j][0] = (GLubyte) c;
checkImage[i][j][1] = (GLubyte) c;
checkImage[i][j][2] = (GLubyte) c;
checkImage[i][j][3] = (GLubyte) 255;
}
}
}
Then setting it
osg::ref_ptrosg::Image image=new osg::Image;
image-setImage(64,64,1,4,GL_RGBA,GL_UNSIGNED_BYTE,(unsigned
char*)checkImage,osg::Image::USE_NEW_DELETE);
[\code]
Please do corrections to my code wherever required.
2)Considering second question I want to find texture coordinate of a particular
point on the model.Using picking I can find the 3d position of an
object,Similarly can I get the assigned texture coordinates at an arbitrary
point using osg??This is similar to contactTexCoord(MFVec3f) in H3D.
Thank you!
Cheers,
Tim
