Re: [osg-users] mouse location (x,y) in pixel units
I found a workaround to my problems, my thanks to Jeremy for pointing a few things out. If I make the following setting: camera->setAllowEventFocus(false); Then in Viewer::eventTraversal() this will avoid setCameraWithFocus(camera); code. As to the reasoning of why there is separate handling for this case in OSG, I don't know. It's certainly an issue that can come up in osgWidget sometime in the future. - Andrew ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

You're right, that there are two ways that the event (X,Y) is calculated, and in
my case, the first branch is used [ if (getCameraWithFocus()) ]. If I comment
out this branch, then the (X,Y) locations can be used correctly (after
transforming them back). One of these two branches will be used, since
pointerEvent is set to true earlier.
I don't think I'm doing anything special with my camera setup (looks pretty
plain vanilla to me),so I'll have to look into it a bit more. Thanks for the
tip.
As a note related to osgWidget, you might want to also keep this issue in mind -
the mouse X,Y can be transformed in a different way, depending on a setting
related to the camera.

I'm just using fairly standard settings. To get CEGUI to render last, I've done
a stateset->setRenderBinDetails( 11, "RenderBin"); for the group containing
CEGUI. As well, I'm using singlethreading for drawing. The rest of the code I'm
trying looks pretty standard...
mViewer = new osgViewer::Viewer();
osg::ref_ptr traits =
new osg::GraphicsContext::Traits;
osg::ref_ptr windata = new
osgViewer::GraphicsWindowWin32::WindowData((HWND)this->Handle.ToInt32());
// Setup traits
traits->x = 0;
traits->y = 0;
traits->width = this->Width;
traits->height = this->Height;
traits->windowDecoration = false;
traits->doubleBuffer = true;
traits->sharedContext = 0;
traits->setInheritedWindowPixelFormat = true;
traits->inheritedWindowData = windata;
// graphics context
osg::GraphicsContext* gc =
osg::GraphicsContext::createGraphicsContext(traits.get());
// new camera initialization
osg::ref_ptr camera = new osg::Camera();
// Assign Graphics Context to the Camera
camera->setGraphicsContext(gc);
// camera viewport
camera->setViewport(new osg::Viewport(traits->x, traits->y,

Re: [osg-users] Point cloud culling/paging
Currently I'm entering all points as 0,0,0 and update them with values
within the render loop.
Except for these:
addPoint(PCPoint(9, 0, 0), PCColor(0,0,0,0));
addPoint(PCPoint(-9, 0, 0), PCColor(0,0,0,0));
addPoint(PCPoint(0, 9, 0), PCColor(0,0,0,0));
addPoint(PCPoint(0, -9, 0), PCColor(0,0,0,0));
addPoint(PCPoint(0, 0, 9), PCColor(0,0,0,0));
addPoint(PCPoint(0, 0, -9), PCColor(0,0,0,0));
Which I wont ever update with new values. I never force an update of the
bounding box.
The farthest extent of a point that I modify should be +/- 1000.
Here is my code for creating the pointCloud:
void PointCloud::factory()
{
_lastEntered = -1;
_geometry = new osg::Geometry();
_geometry->setSupportsDisplayList(false);
_geometry->setUseDisplayList(false);
_cloud3DRep = new osg::Geode();
_points = new osg::Vec3Array();
_colors = new osg::Vec4Array();
PCPoint p(0,0,0);
PCColor c(0,0,0,0);
double px, py, pz, cr, cb, cg, ca(1.0);
for (int i = 0; i < _maxSize; i++)
{
_points->push_back(p);
_colors->push_back(c);
}
_geometry->setVertexArray(_points.get());
_geometry->setColorArray(_colors.get());
_geometry->setColorBinding(osg::Geometry::BIND_PER_VERTEX);
_geometry->addPrimitiveSet(new
osg::DrawArrays(osg::PrimitiveSet::POINTS, 0, _maxSize));
_cloud3DRep->setCullingActive(false);
_cloud3DRep->addDrawable(_geometry.get());
addChild(_cloud3DRep.get());
osg::StateSet *set = new osg::StateSet();
/// Give some size to the points to be able to see the
sprite
osg::Point *point = new osg::Point();
point->setSize(2.0f);
set->setAttribute(point);
/// Disable depth test to avoid sort problems and
Lighting
set->setMode(GL_DEPTH_TEST, osg::StateAttribute::OFF);
set->setMode(GL_LIGHTING, osg::StateAttribute::OFF);
_cloud3DRep->setStateSet(set);
addPoint(PCPoint(9, 0, 0), PCColor(0,0,0,0));
addPoint(PCPoint(-9, 0, 0), PCColor(0,0,0,0));
addPoint(PCPoint(0, 9, 0), PCColor(0,0,0,0));
addPoint(PCPoint(0, -9, 0), PCColor(0,0,0,0));
addPoint(PCPoint(0, 0, 9), PCColor(0,0,0,0));
addPoint(PCPoint(0, 0, -9), PCColor(0,0,0,0));
}
And my code for editing each point:
void PointCloud::addPoint(PCPoint p, PCColor c)
{
//if we hit the end of the array start at the beginning
_lastEntered++;
if (_lastEntered >= _maxSize && _maxSize >= 0)
_lastEntered = 0;
(*_points.get())[_lastEntered] = p;
(*_colors.get())[_lastEntered] = c;
}

Hi
Sounds like it could be a bounding sphere/box issue
How are you loading and creating the point cloud ?
You might possibly have one or more errant points that are out side the
range/volume of all the other points of a geode
Depending on how your loading/creating the geodes, you should check the
bounding box/spheres against the expected
Extents of the point cloud for the geode etc...

Again, I never get the normalized values in osgWidget (and haven't since
I began writing it). This has to have something to do with the kind of
camera the event appears within, as looking through the code I see that
the event{X,Y} values are calculated two different ways depending on
whether a function getFocusedCamera() returns true or not...
How is your scene laid out? I've never used CEGUI with OSG, so I'm not
sure how people in the past have done it.

Re: [osg-users] mouse location (x,y) in pixel units
Hello Donald, I actually tried something along the lines of what you wrote: int my_x = (int) ( ((ea.getX() + 1.0) / 2.0) * 640.0 ); int my_y = 480 - (int)(((ea.getY() + 1.0) / 2.0) * 480.0); Your lines basically do the same thing (except flip the y axis). However, my problem is that the mouse tracking in x is still off by a little bit, especially near the left and right hand side of the screen. It appears that the values in OSG aren't exactly normalized as expected (e.g. with getXnormalized() ). I even tried the following code, but it didn't solve my problems with the tracking in x: int my_x = (int) ( ((ea.getXnormalized() + 1.0) / 2.0) * 640.0 ); int my_y = 480 - (int)(((ea.getYnormalized() + 1.0) / 2.0) * 480.0); This is why I'm trying to get the raw pixel position.

Re: [osg-users] Race conditionUpdateCallbackvsGLCompileObjectVisitor ?
Hi Robert,
Attached is a modified version of prerender.cpp.
Waving flag geometry has commented /*setSupportsDisplayLists( false )*/ to
actually allow display list compilation on it.
Without display list compilation, race condition existed but did not cause
obvious visual problems in this example, because drawable was actually
applied in draw phase. It was possible to notice it in Debugger, though.
I modified update callback to set flag color to red at the beginning, wait
one second (to see results and yield control to other threads) and set
colour to green just before returning from update callback.
In other words if gl compile objects gets called concurently with update it
will be possible to see red flag.
If everything is fine we should constantly see green flag. (See attached
screenhots)
My Testing (Windows XP, NVidia 7800, Athlon x2)
Red flag is always shown at application startup on first frame then
changes to green in subsequent frames.
If one is lucky, red can be also noticed when threading mode gets
changed with threading handler (does not happen always).
I hope this test is reproducible at your site ;-)
I am going home now, will be back tomorrow.
Cheers,
Wojtek Lewandowski

Thanks for pursuing this. I wouldn't have thought this is a windows
specific issue, but.. threading bugs are often hard to reproduce and
track down, slight timing differences can mean a crash or not, so
slight differences in timing across platforms can make it seem like
the problem is platform specific when it isn't really.
Distilling an example down to what makes it break, and charaterising
when and where it happens is what will lead us to properly
characterising the problem, the shortly after this it's likely we'll
know how to fix it.
FYI, on multi-threading rendering to texture effects on my dual head
machine I do see occasional flickers that suggest a threading issue,
but I don't see a crash, but there is a least a hint that things
aren't quite right.
Robert.

from a quick look, it appears your geometry is just two adjacent quads (ie 4 triangles), no? No need to invoke a tesselator for a concave polygon. Just use 3 verts for each of the 4 triangles (12 verts total) and draw as GL_TRIANGLES. cheers -- mew On Wed, Apr 23, 2008 at 2:34 PM, R Schwantes <[EMAIL PROTECTED]> wrote: > Hi list, > > I've been a long time lurker.

Hi All long suffering testers! ;-) I have just tagged 2.3.11, the release candidate 3 for OSG-2.4, details can be found at: http://www.openscenegraph.org/projects/osg/wiki/Downloads/DeveloperReleases * OpenSceneGraph-2.3.11, released on 24th April 2008. OpenSceneGraph-2.3.11 is the 3rd release candidate for 2.4. Minor changes are to NEWS, ChangeLog?, AUTHORS, and a small tweak of osgDB for Quicktime live plugin support, and Win32 build support of libcurl. source package : OpenSceneGraph-2.3.11.zip svn tag: svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.3.11 OpenSceneGraph I'd appreciate any further testing that you can muster, my plan is that this is our last release candidate, and baring major problems will tag OSG-2.4 tomorrow morning.

Re: [osg-users] Point cloud culling/paging
Thanks for the reply. I thought the near clippling plane might have been the problem but its not clipping the terrain adjacent to the points. It also makes me wonder why this would only happen if the terrain is visible. I've set my near clipping plane to .1 and the far to 1000. The camera I'm using is the default one created by the viewer. double fovY, aspectRatio, near, far; mcam->getProjectionMatrixAsPerspective(fovY, aspectRatio, near, far); mcam->setProjectionMatrixAsPerspective(fovY, aspectRatio, .1, 1000); mcam ->setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR); mcam ->setCullingMode(osg::CullSettings::NO_CULLING); Even with these settings the problem still occurs.

[osg-users] Point cloud culling/paging
I'm experiencing some weird problems with my point cloud. I have a fairly large terrain and a point cloud that expands the whole terrain. When I build the point cloud and look around the environment whole sections of the point cloud disappear when they aren't centered within the camera's view. They will then reappear when the center of the missing section is within view. The point cloud is a POINTS primitive set and I have turned culling off (setCullingActive(false)) as well as display lists. I've noticed that if I do not add the terrain model to the scene it works ok. What culling/paging option do I need to set to make sure this doesn't happen? -Steve ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Race condition UpdateCallback vsGLCompileObjectVisitor ?
Hi Wojtek, Thanks for the explanation. I don't see any crashes here unfortunately, it's typically a relief when I can as it gives a chance of debugging first hand. I've done of a review of the ViewerBase.cpp and Renderer.cpp codes that are responsible for set up the threading and running the draw traversals and it looks to me like the DataVariance changed should prevent the next frame from advancing before the GLObjectVisitor has completed. I would have liked to get this bug fully characterised and fixed before 2.4, but given how close we are to the release, and how open ended this quest might be, I feel that we should push ahead on 2.4, and in the 2.5.x dev series fully shake down the multi-threaded RTT beast.

Re: [osg-users] osg::SceneView thread model
Hi Erland, osg::Camera has threading support, but this is in support of osgViewer, and isn't used at all by SceneView. SceneView simple knows nothing about threading, it really just existing for backwards compatibility for old apps, and temporarily within osgViewer as an implementation detail, its something that will be replaced though. As for integrating osgViewer with existing renderers/apps, this is what osgViewer::GraphicsWindowEmbedded can help out with. See osgviewerGLUT and osgviewerSDL for examples of it in action. This makes it easy to embed a viewer into an existing window without any need for complex wiring up of windows. Robert.

I wouldn't have thought this is a windows specific issue, but.. threading bugs are often hard to reproduce and track down, slight timing differences can mean a crash or not, so slight differences in timing across platforms can make it seem like the problem is platform specific when it isn't really. Distilling an example down to what makes it break, and charaterising when and where it happens is what will lead us to properly characterising the problem, the shortly after this it's likely we'll know how to fix it. FYI, on multi-threading rendering to texture effects on my dual head machine I do see occasional flickers that suggest a threading issue, but I don't see a crash, but there is a least a hint that things aren't quite right.

osgWidget does this, and converts the origin to the upper-left instead of lower-left in the WindowManager object just using getX/getY. They have never returned "normalized" coordinates in my usage... but perhaps I've been benefiting from a bug all along...?

[osg-users] mouse location (x,y) in pixel units
In OSG2.2 I'd like to find the 'real' x,y location of the mouse cursor. If my window is 640x480, then the value for x should be between 0 and 639, while y should be from 0 to 479. I need the x,y values in this form so that it can be injected into CEGUI correctly. The GUIEventAdapter has protected members _mx and _my, along with the access methods getX() and getY(). However, these methods both yield values between -1 and 1. While stepping through the code, the _mx and _my actually correctly hold the pixel based values I need until encountering the following section in Viewer.cpp: osg::Vec3d new_coord = osg::Vec3d(x,y,0.0) * matrix; x = new_coord.x(); y = new_coord.y(); ... event->setX(x); event->setY(y); Aside from making private changes on GUIEventAdapter, is there any other way to read the mouse x,y location in the format I need? All suggestions are very much appreciated. Sincerely, - Andrew ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Race condition UpdateCallback vsGLCompileObjectVisitor ?
Hi Robert, > What issues were you seeing at your end? Also how did you monitor the > race condition? > Did problems still occur after you added the DataVariance setting? I have some time now, and I decided to investigate what is the context of these Windows/multimonitor/multithread/FBO crashes. I don't have any hard evidence but usually when such crashes occured I had some GLObjectsVisitor traversals on the call stack. So I started to debug with VS 2008 and after some breakpoint stop I noticed such case on Threads/Cull Stack. I was surpirsed to see that one thread was inside drawable->apply( state ) method and main thread was in Update Callback. I noticed that drawable did not have DYNAMIC variance set so I added it but issue did not disappear. I believe that when threading is stopped and restarted GLObjectsVisitors are invoked. So I started to suspect that this race condition might be involved in crashses when changing threading modes with Threading Handler. I suppose multimonitor use might be also affect it somehow (at least initialization of synchronization barriers and blocks is). Currently I am further investigating it by freezing and activating some threads and stepping through selected threads but I am freely able to repeat this scenarios without deadlocks(caused by my debug thread suspends). So it looks like synchronization blocks and barriers do allow for such case. Of course without my manual interventions it does not happen so often but it still occurs every few runs.

AFAIK osg::Hint(GL_LINE_SMOOTH_HINT, GL_NICEST) worked well for me under 2.0, 2.2, 2.4, no idea bout pre 2.0 though. Note that smoothing works also without setting such flag, that's simply an hint sent to the driver which is free to ignore it or interpret it in which ever way.

Hi Luigi,
Thanks for the note, its nice to know why what I did din't work. I've
gone ahead a reverted the change as it looks like the build problem
under OSX due to the headers is most likely a CMake bug, and for
frameworks these headers will actually be needed, so once the CMake
side is fixed this problem should go away, if we remove the headers
then we'll preclude the frameworks side from working.

How the OpenGL driver responds to the that State is down to the driver/hardware. In the case of line smoothing I believe that you still need to enable GL_LINE_SMOOTH even when using the hints, the mode simply enables the use of filtering that the hints specify. Robert.

Re: [osg-users] OS X / cmake-problems, was: Re: OpenSceneGraph-2.3.10 dev release tagged
I think the problem with recent changes not showing headers in
VisualStudio, is related to a typo:
the ELSEIF in this context is bad:
so, instead of reverting patches, at least under visualstudio, one can
substitute
ELSEIF(APPLE) with ELSE(APPLE)
so
IF(APPLE)
SET(ADD_LIBRARY_HEADERS "")
ELSE(APPLE)
SET(ADD_LIBRARY_HEADERS ${LIB_PUBLIC_HEADERS} )
ENDIF(APPLE)
then the headers appers again
Hope it helps

Re: [osg-users] antialiased lines
Ciao Gialluca, you absolutely need to enable GL_LINE_SMOOTH and GL_BLEND and to setup a blending function like for example osg::BlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA). The same goes for GL_POINT_SMOOTH.

Drawable has DYNAMIC data variance > set. I must admit to not having thought about the issues of GLObjectsVisitor running in parallel with the update traversal. GLObjectsVisitor isn't part of the rendering back end that knows about DataVariance being critical, and it isn't really something that should need to - what should be happening is that the osgViewer itself should hold back the next frame till the GLObjectsVisitor has completed. I'll have a look at the code to see if I can spot a straight forward fix.

[osg-users] Race condition UpdateCallback vs GLCompileObjectVisitor ?
Hi Everyone,
Is it normal to see UpdateCallback runninig concurently with GLObjectsVisitor
on the same drawable ? Drawable has DYNAMIC data variance set.
If the anwer is not, then I will tell a bit about the example code. Its
osgprerender ran by default in DrawThreadPerContext ? All I did was adding
DYNAMIC data variance to waving flag geometry and 1 second sleep to update
callback to slow down drawing to see the changes beetween frames. I have added
standard ViewerHnadlers but they dont affect this case. Code attached.

Re: [osg-users] Please test SVN of OpenSceneGraph
Hi All, I have just reverted yesterdays changes that I made to the various CMakeLists.txt files, and also merged a fix the Windows 3rd party checking sent in my Mattias, these changes are all now in SVN. So... Could you please do another svn update and build to make sure that things are still working fine. Under OSX there may be problems left unresolved with the CMake build but these I'm afraid we'll need to live with for 2.4, so the hand maintained XCode projects will remain the official build route for OSX. Under Windows Visual Studio build could you please check to see if header files are now coming in correctly. Once I have positive reports of builds under Windows, OSX and the unices I'll tag 2.3.11, then tag 2.4 tomorrow morning.

Re: [osg-users] antialiased lines
Hi Gianluca, The OSG just passes state along to the OpenGL, the glHint support is just another means to setting OpenGL state. How the OpenGL driver responds to the that State is down to the driver/hardware. In the case of line smoothing I believe that you still need to enable GL_LINE_SMOOTH even when using the hints, the mode simply enables the use of filtering that the hints specify. Robert.

[osg-users] antialiased lines
Hi OSG developers! I'm trying to draw antialiased lines with OSG ver .2.2, but I'm having problems. This is my code: osg::ref_ptr antialiasHint = new osg::Hint(GL_LINE_SMOOTH_HINT, GL_NICEST); StateSet->setAttributeAndModes(antialiasHint.get(), osg::StateAttribute::ON); Obviously I've also set a blending function. Is there something wrong in my code, or a well-known bug in OSG 2.2? Note that in OSG ver. 1.2 I obtained the same effect just by calling: StateSet->setMode(GL_LINE_SMOOTH, osg::StateAttribute::ON); This still does work in OSG ver 2.2, but I wanted to update my code to the correct use of glHint under OSG.

Re: [osg-users] Newbie question about concave polygons
Hi Schwantes, yes, OpenGL (and DirectX) don't directly support concave polygons, you have to use several triangles to make a polygon look concave. You don't really need a Tessellator, you could simply divide your concave polygon in a bunch of triangles like in the attached picture. You simply specify a vertex for each corner of each triangle and then call: geom->addPrimitiveSet(new osg::DrawArrays(GL_TRIANGLES, 0, vertices->getNumElements())); Good luck, Michele On Wed, Apr 23, 2008 at 9:34 PM, R Schwantes <[EMAIL PROTECTED]> wrote: > Hi list, > > I've been a long time lurker.

Re: [osg-users] OS X / cmake-problems, was: Re: OpenSceneGraph-2.3.10 dev release tagged
Hi Eric,
Thanks for chiming in.
Looks like I'll have to revert the header change then... and leave
resolution of the problems that Stephan has seen to a later CMake &
OSG revision.
Robert.

Re: [osg-users] GLSL Setting up gl_EyePlane
Hi Paul, > Hi,Just a small one - > Are the gl_EyePlanes automatically setup when calling > texgen->setPlanesFromMatrix(...)? > > I'm trying to replicate simple Projective texturing using glsl. I am not sure what you mean by automatically... It will be applied to OpenGL in draw phase. When used with TexGenNode it will be applied globally for whole render stage nad used for all the scene. If used as TextureStateAttribute it will be applied by lazy state update when drawables using this attribute are drawn. Small warning: If you intend to use EYE_LINEAR TexGen as a texture state attribute it won't most probably work as you expect. Its due to unpredictability of glModelView matrix which will be current when TexGen gets applied by lazy state update. Basically TexGen as texture state attribute will work in predictable way with modes that use vertex coords (not require eye coords).

Re: [osg-users] GeoTIFF dem coordinate system?
Hi Linh, VPB/osgdem decorates databases with a CoordinateSystemNode which will record the cooridnate system it uses. VPB does default to using WGS84 when working geocentric, but you haven't mentioned any of the osgdem options so I can't really say whether this will have been applied. I must admit I have yet to work with anything other than earth bound imagery/dem's so have not been able to test it out on other planetary data. Would it be possible to provide me with some? Robert.

Re: [osg-users] Please test SVN of OpenSceneGraph
Hi Robert, all, Quick note while I'm building after starting fresh after delete of cmake cache. It didn't find the curllib in Mike's 3rdParty since Find3rdPartyLibraries only searches for libcurl and not culrlib.
