Re: [osg-users] Callbacks: operator() call
Hi, To use a lot of callback, you need to verify that you call *traverse(node, nv);* at the end of each callback operator() to continue traversing the graph. If I'm right, all the callback are traversed at each frame, during the update (for the updatecallback) and is it not done in a parallel thread. Regards, Vincent. 2008/10/29 Renan Mendes [EMAIL PROTECTED] Hi, I'm having some trouble when using a whole lot of callbacks at the same time... Apparently it has something to do with the order that they're being called. I want to know how is it done. Are the operator()'s executed one by one in a given order or are they executed in a parallel manner?

Re: [osg-users] If I want to use wxWidgets with OSG, do I need a particular version of wxWidgets?
Hi,
I've had my share of problems with this of late as well, but managed to
get everything working. You have to indeed manually enable OpenGL
support when building wxWidgets.
To do so, you need to edit the 'master setup.h file'. This file can be
found at include/wx/your build platform (as described at
http://wiki.wxwidgets.org/Setup.H). Change the value of
WX_USE_GLCANVAS from 0 to 1. Then, rebuild the lot.

[osg-users] Camera rotation on three axes
I'm trying to rotate a camera on all axes but my code fails when the x-axis or y-axis rotation approaches 90 degrees. I am using a viewer.frame loop to avoid the default manipulator supplied by viewer.run. My current camera code is : cameraRotation.makeRotate ( yrads,osg::Vec3 (0, 1, 0) , // roll Y xrads,osg::Vec3 (1, 0, 0) , // pitch X zrads,osg::Vec3 (0, 0, 1) ); // yaw Z cameraTrans.makeTranslate (xdist, ydist, zdist); myCameraMatrix = cameraRotation * cameraTrans; inverseMatrix = myCameraMatrix.inverse (myCameraMatrix); inverseMatrix *= osg::Matrixd::rotate (-(osg::PI_2), 1, 0, 0); viewer.getCamera ()-setViewMatrix (inverseMatrix); When the pitch (xrads) is 0 everything works properly. But when xrads is PI/2 the effect of yrads is identical to zrads (both do z-axis rotation). I've tried applying the rotations in various orders but the code fails when one of the rotations is PI/2. Can anyone suggest what I am doing wrong here or point me to a sample of working code ?

Re: [osg-users] auto-capture example: capturing an image from a PagedLOD Database
Hi Robert,
I made it work! However, to make the example work I had to a new
statistics counter to DatabasePager. I added the method the DatabasePager:
/** Get number of fileRequest that are currently being processed in
DatabaseThreads */
int getRequestsInProgress() const { return _requestsInProgress; }
The member _requestsInProgress is intialized to zero in the
DatabasePager c'tors, increased by one in
DatabasePager::requestNodeFile(), and decreased by one in
DatabasePager::addLoadedDataToSceneGraph();
This counter in the DatabasePager allows me to use the following
algorithm in the custom viewer class:
...
// Initiate the first PagedLOD request
frame();
// Keep rendering until full level of detail is reached
while(!done() getDatabasePager()-getRequestsInProgress())
{
updateTraversal();
renderingTraversals();
}
// Add the WindowCaptureCallback now that we have full resolution
getCamera()-setFinalDrawCallback(new
WindowCaptureCallback(GL_BACK, _fileName));
renderingTraversals();
// Automatically close after capture
close();
...
Although this works, it takes a looong time for the program to capture
the full-res image. I'll send the example and DatabasePager mods to
osg-submissions, and I hope the community can find a better / faster way
to implement this example.
I think such a solution is needed for OSG to support auto rendering jobs
(command line / cronjob), whether the output is in form of images or
movies. One usage example is to render the same animation path each day
over a terrain, but with different data overlays (e.g. weather,
pollution, traffic, etc.) And you want your movies / images to be crisp;)
Best regards,

Re: [osg-users] DatabasePager questions
Hi Rick, The osgDB::DatabasePager::instance() exist for backwards compatibility with osgProducer from the OSG-1.x era. In OSG-2.x's osgViewer library there is one osgDB::DatabasePager per osgViewer::Scene, and the Scene is used internally by osgViewer::View to manage the sharing of a single scene graph between multiple View's. The coupling of DatabasePager and Scene ensures that there is only ever one pager working for one scene graph. It also allows multiple scene graphs to be managed, each with their own dedicated pager. In terms of user management, this is all done behind the scenes in osgViewer, it'll just automatically assign and set up and interact with the pager, you needn't do anything yourself. If your scene graph contains PagedLOD then it'll automatically start up and run in the background. The only time you need to know about the DatabasePager is when you want to adjust parameters to optimize the behavior to your type of data/application, but the since the defaults have been chosen to work well for most datasets users typically won't need to tweak parameters.

It seems the design of osgDB::DatabasePager allows for multiple instances of it to exist side-by-side. Scene creates one instance in it's constructor, and if you call Registry::getOrCreateDatabasePager without setting a pager up, it creates another instance. The first uses the Database::create function, whereas the second uses a simple 'new'. This has caused us some issues as we only expected there to be a single instance of osgDB::DatabasePager. What is the reason for explicitly allowing this functionality? It may simply be to do with the way we have the DatabasePager setup, but my lack of a higher view of the code is making it hard to understand what's supposed to happen.

Hi John,
I'll do a review of the submission and provide a bit more in the way
of thoughts once completed.
In terms of possible optimizations, disabling the precompile and only
doing the update, event, and cull would be probably the most efficient
way to get tiles loaded, then once the tiles are loaded do the final
render. The awkward part of this is that the cull and draw are
closely coupled in the Viewer...
One way around this would be just write a custom CullVisitor that
kicks of the database request for a given camera set up.

Subject: Re: [osg-users] auto-capture example: capturing an image from a
PagedLOD Database
Hi Robert,
I made it work! However, to make the example work I had to a new statistics
counter to DatabasePager. I added the method the DatabasePager:
/** Get number of fileRequest that are currently being processed in
DatabaseThreads */
int getRequestsInProgress() const { return _requestsInProgress; }
The member _requestsInProgress is intialized to zero in the DatabasePager
c'tors, increased by one in DatabasePager::requestNodeFile(), and decreased
by one in DatabasePager::addLoadedDataToSceneGraph();
This counter in the DatabasePager allows me to use the following algorithm
in the custom viewer class:
...
// Initiate the first PagedLOD request
frame();
// Keep rendering until full level of detail is reached
while(!done() getDatabasePager()-getRequestsInProgress())
{
updateTraversal();
renderingTraversals();
}
// Add the WindowCaptureCallback now that we have full resolution
getCamera()-setFinalDrawCallback(new WindowCaptureCallback(GL_BACK,
_fileName));
renderingTraversals();
// Automatically close after capture
close();
...
Although this works, it takes a looong time for the program to capture the
full-res image. I'll send the example and DatabasePager mods to
osg-submissions, and I hope the community can find a better / faster way to
implement this example.
I think such a solution is needed for OSG to support auto rendering jobs
(command line / cronjob), whether the output is in form of images or movies.
One usage example is to render the same animation path each day over a
terrain, but with different data overlays (e.g. weather, pollution, traffic,
etc.) And you want your movies / images to be crisp;)
Best regards,
John

Hi Robert,
Are you planning to submit this example for inclusion with the OSG
example set? If so then I could integrate then I and others could
tweak it so it works.
Yes, that was basically the plan, only that I originally wanted to submit
a working example;)
The reason for putting together this example in the first place was to
create an application scenario that could make it interesting for others to
solve this particular DatabasePager problem as well.
I'll try out a few more hunches before cleaning up and submitting the
example, working or not working.

Re: [osg-users] DatabasePager questions
Thank you Robert for the quick reply. I see the point in having a single osgDB::DatabasePager for a single osgViewer::Scene. However, this immediately raises the question which DatabasePager osgDB::Registry would point to, as osgDB::Registry is a singleton and only has a single pointer to a DatabasePager. Should we ignore the osgDB::Registry::getOrCreateDatabasePager function? I don't see it being used anywhere in OpenSceneGraph. Kind regards, Rick -Original Message- From: [EMAIL PROTECTED] on behalf of Robert Osfield Sent: Thu 10/30/2008 12:57 PM To: OpenSceneGraph Users Subject: Re: [osg-users] DatabasePager questions Hi Rick, The osgDB::DatabasePager::instance() exist for backwards compatibility with osgProducer from the OSG-1.x era. In OSG-2.x's osgViewer library there is one osgDB::DatabasePager per osgViewer::Scene, and the Scene is used internally by osgViewer::View to manage the sharing of a single scene graph between multiple View's. The coupling of DatabasePager and Scene ensures that there is only ever one pager working for one scene graph. It also allows multiple scene graphs to be managed, each with their own dedicated pager. In terms of user management, this is all done behind the scenes in osgViewer, it'll just automatically assign and set up and interact with the pager, you needn't do anything yourself. If your scene graph contains PagedLOD then it'll automatically start up and run in the background. The only time you need to know about the DatabasePager is when you want to adjust parameters to optimize the behavior to your type of data/application, but the since the defaults have been chosen to work well for most datasets users typically won't need to tweak parameters.

It seems the design of osgDB::DatabasePager allows for multiple instances of it to exist side-by-side. Scene creates one instance in it's constructor, and if you call Registry::getOrCreateDatabasePager without setting a pager up, it creates another instance. The first uses the Database::create function, whereas the second uses a simple 'new'. This has caused us some issues as we only expected there to be a single instance of osgDB::DatabasePager. What is the reason for explicitly allowing this functionality? It may simply be to do with the way we have the DatabasePager setup, but my lack of a higher view of the code is making it hard to understand what's supposed to happen.

I assume you have modified texgen matrix but not shadow camera projection matrix (the one involved in computation of texgen matrix) ? If shadow camera projection gets modified it could potentially affect rest of the code. I don't know. I read on the mailing list that there is an issue with FBO textures on ATI, because at some point, ATI inverted the 't coordinate' in their drivers. http://archive.netbsd.se/?ml=openscenegraph-submissionsa=2008-02m=6605417 Actually, one idea just came to my mind, MinimalDrawBoundsShadowMap does rough depth map prerender to compute visible shadowed scene extents. I suppose reverted vertical texture coordinates may also affect this code. You may look at MinimaDrawBounds line 203 - its the place where matrix for prerenderd image scan is computed - and you may need to make the fixes there. As a alternative approach, you could try LightSpacePerspectiveShadowMapCB and see if the problem is also present ? LightSpacePerspectiveShadowMapCB variant computes shadowed volume by scanning boxes around drawables in render bins and should avoid at least this potential prerenderd image scanning issue. OK, I quickly tried LightSpacePerspectiveShadowMapCB but the problem was still present. Unfortunately I didn't have enough time to take a good look at the prerendered image scan computation. I will keep looking into tomorrow, starting at the MinimalShadowMap level as this seems to be the lowest level at which the problem occurs on my system. Good luck. And let me know if you come up with some constructive conclusion, possible fixes or workarounds. Thanks, and I will certainly let you know if I find something! Cheers, Rick. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] CompositeViewer event delivery bug? [patch included]
Hi,
I use osgViewer::CompositeViewer with several views. All views share
parts of their scene graphs. Within these common part some nodes have
event handlers which use the action adapter argument to the event
handler to determinate which view received the event.
Here is the problem, osgViewer::CompositeViewer::eventTraversal sets
the action adapter field in the EventVisitor always to the last view
which received an event, instead of using the view which actually
received the event, so determination of the correct view does not work.
I looked at the code a bit, and moved the code for setting the action
adapter to a IMO better place.
btw, on every mouse move all views seem to receive FRAME events, is
that normal or is it some glitch within my application?
thanks in advance, thomas

[osg-users] osgManipulator::Dragger and osg::AutoTransform
Hi guys, Once again, a question about something pretty specific, so bear with me please... I want an osgManipulator::Dragger to be always the same size on the screen, independently of how far away the camera is (if someone is familiar with Maya, something like that). So I thought putting it under an osg::AutoTransform with autoScaleToScreen = true would be ideal. Unfortunately, since the dragger stores its transform in its own matrix, the dragger now moves in pixel increments instead of in world unit increments. The object I'm manipulating moves correctly when I drag the dragger, but the dragger doesn't follow. Is there a way to get the AutoTransform to only affect the scale, and not other parts of the transformation matrix? Or is there some other way to do what I want to do? I thought perhaps the dragger could resize itself by listening to FRAME events or something like that and then determining the proper size. Has anyone done this before?

Re: [osg-users] OSG and C# Users
Hi Maya, It's hard to tell what could be going on without some more information about your setup. One thing you should try is setting the OSG_NOTIFY_LEVEL environment variable to DEBUG to help get a clue of what is going on. If you build your app as a Console application you will see all of OSG's debug messages and might point you to the problem. I'm grasping at straws here and just guessing, but if you are using an OpenFileDialog to load your models, make sure that that RestoreDirectory property is set to true. If not, it will change your applications working directory and OpenSceneGraph won't know where to find your plugins.

Re: [osg-users] Shadows in osgviewerQT ?
Hi, OK so I figured out that my problems are due to using AdapterWidget - I understand that shadows etc. should work fine with QOSGWidget. Unfortunately QOSGWidget doesn't work here: the widgets remains white and Qt prints warnings about recursive repaint. I've checked out the latest OSG trunk and tried with that but get the same result (actually it segfaults due to a bogus ifdef in the QOSGWidget source code - I'll send over a patch shortly - but after fixing that I get the same result.) I've started tracking down the problem, so far the only thing that I figured out is that GetWindowPort always seems to return 0 for the QOSGWidget's native peer - is that expected? I'm using Qt 4.4.3 on an Intel Mac with OS X 10.5. The Carbon code paths are used, not X11. Are there any known problems with QOSGWidget with Qt 4.4, OS X 10.5 or with the Carbon peers? Thanks in advance, Julian On Thu, Oct 30, 2008 at 3:30 AM, Julian Scheid [EMAIL PROTECTED]wrote: Hi, I'm trying to embed osg in a Qt4 application. I've had some troubles with FSAA/multisampling but managed to work around it by configuring the QGLWidget for FSAA instead of osg. However, I'm now trying to get shadows to work based on the osgshadow code, and it seems that no matter which shadowing technique I try it brings my machine to a grinding halt - the whole screen starts to flicker wildly, circles and balls reminiscent of Katamari Damacy are drawn into the scene, and when continuous update (via timer) is enabled I have no recourse but to restart my machine. (This is one of the new Intel Macbooks running OS X 10.5) I gather that when embedded in Qt, the GraphicsWindowCarbon code isn't used and osg just uses the existing GL context. Does that mean that I would have to manually setup Qt's GL context and somehow synchronize it with osg's shadow magic? If all that is meant to be supported in the Qt viewer, is there any chance you could add an example for this situation?

Re: [osg-users] TrackballManipulator asymptote
thanks again Robert - now I better understand how TrackballManipulator works. I overloaded the calcMovement() function to move consistently and it is working well. Richard Hi *Richard*, The trackball slows as you move into the origin as the rate of movement in is always a percentage of distance from the center to the eye point. This is just the way it works, it's not some that can be fixed as it's doing exactly what it's meant to do. Now if you want some custom manipulator that kinda behaves like the TrackballManipulator then you'll need to subclass or just write your own from scratch. One hack you could implement is the pushing forward of the center as you get near to it, rather than just keep reducing the distance between the eye and the center.

Re: [osg-users] OSG and C# Users
Hi Maya, I'm not sure why the osgdb_jpegd.dll would fail to load, hard to say. One thing to note is that osgviewer works, but what about osgviewerd? From the debug output, you are running your app in debug mode. Try running in release and see if it works. I'll bet that osgviewerd doesn't work.

One thing you should try is setting the OSG_NOTIFY_LEVEL environment variable to DEBUG to help get a clue of what is going on. If you build your app as a Console application you will see all of OSG's debug messages and might point you to the problem.

[osg-users] Cull-Traversal Performance
Hi Folks, First off, let me say that it's good to be back on the list - it has been awhile ;-) I'm trying to tune a scene-graph representing a relatively-large model. I'm seeing what I think are abnormally long cull-traversal times. The SG looks as follows: (State is constant across the entire scene) [Group] x 1 | [Switch] x 1 | [MatrixTransform] x 100 | [Geode] x 1 | [Geometry] x 100 There are approx 10K Geometry Drawables in the overall scene. The cull traversal for this scene graph is approx 10ms on a 2.5GHz Core2Duo processor. If I change the SG to the following: [Group] x 1 | [Switch] x 1 | [MatrixTransform] x 100 | [Switch] x 1 | +-+ | | [Geode] x 1 [MatrixTransform] x 100 | | [Geometry] x 100 [Geode] x 1 | [Geometry] x 1 and I turn on the new branch, the cull traversal jumps to 80ms. If I eliminate the single Geometry node below the new geode (so that the new branch is still there, but doesn't draw anything, cull-traversal falls to 40ms. Can anyone help explain what is going on here? These cull-traversal times seem long relative to the complexity of the scene and the speed of the processor - I'm trying to hit a 60Hz frame-rate, and even 10ms for the cull is just not going to cut it. For better or worse, there isn't a good way to simplify the complexity of the scene. cheers, sean ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
