[osg-users] getColorIndices usage
Hello all OSG users, does anyone know how to use the Geometry::getColorIndices() method? I do not know how to work with the returned IndexArray - how to access and change the values. My situation: Geometry uses generally one color and sometimes it's necessary to draw some primitiveSets by another color. So, I use BIND_PER_PRIMITIVE_SET, colorArray has one element and colorIndices is: /*copied from OSG pyramid example, I do not know what last 2 params DataSize and DataType 4,4 mean :( */ osg::TemplateIndexArrayunsigned int, osg::Array::UIntArrayType,4,4 *colorIndices; colorIndices = new osg::TemplateIndexArrayunsigned int, osg::Array::UIntArrayType,4,4; (for every primitiveset) colorIndices.push_back(0); ... . This works fine, but now I want to change index in colorIndices array, but I do not know how to access the data in IndexArray* that is returned by Geometry::getColorIndices(). I tried to dynamic_cast to osg::UIntArray*, but such cast does not work. (like Vec4Array* works for getColorArray()) Any ideas how to access and work with the colorIndices array? Or is it necessary to remember the array as osg::TemplateIndexArray and use only setColorIndices - but if so, then why getColorIndices() exists?

Re: [osg-users] Performance hit caused by porting from VS 7.1 to VS 9
Hi Rick, Do the express editions do full optimizations? I recall previously MS used to cap the optimization on the give away versions of VS. Robert.

Thanks again for all the fantastic forum support. We have been using VS 7.1 for all of our work so far, but since we were missing a well build freetype library, I figured it was time to make the jump there as well.

The converter in VS 9 converted all of the projects without fuss, and I was able to get it all compiling and running pretty easily. Unfortunately, I am seeing this 30% drop in framerate :(. I was seeing about 28-30 fps (yes, I know, I have some scene optimizing to do) with the VS 7.1 build, which dropped to 20-21 fps using VS 9 express. Has anyone seen anything like that before?

Is the only current option to drop down to osgViewer::Viewer, or will doing a current SVN checkout resolve it? -(from J-S G., 28feb08) Look closely - the scene moves, just *very very* little. It's a bug in osgViewer/CompositeViewer.cpp which I submitted a fix for about a week ago. When a single view is on multiple displays (so the slave camera mechanism in osgViewer::View is used) the viewport extents are not set correctly in the eventTraversal, so when the mouse events are translated they have wrong values and the mouse movement has very little effect. -- Bob. ___ 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] getColorIndices usage
Hi Thomas, I can only guess the tutorial your are copying has rather awkward usage of the OSG, in normal OSG usage you would never reference the TemplateIndexArray template directly, rather just use the typedef UIntArray. As for color indices, please don't use them unless you really really need to. The vertex array indices exist because in the early days of the OSG I was working with a client porting from Performer to OSG and in this case adding per vertex array indices support helped them. I have however regretted this addition ever since, as the feature end up being used when it really shouldn't be. My plan is to move the array indices out of osg::Geometry to prevent for inappropriate use. Why is it inappropriate? Well OpenGL doesn't itself support separate index arrays for the different vertex arrays, it only supports glDrawElements that provide index access to all active vertex arrays in a parallel, to support the separate index arrays you have to simulate it by dropping down to OpenGL slow path i.e. glBegin/glEnd, this is really slow unless you hide the cost by wrapping it all in a display list and even then it still won't be as fast as using . It far far more efficient to repeat colours to get the effect than to use per array indices, it might be more data you are managing but it used OpenGL fast paths. Robert.

[osg-users] Dramatic increase in event traversal time during mouse movement
Hello, group! I was looking at the nice statshandler graphics in osgViewer.exe, and noticed a dramatic increase in the time spent in the event traversal stage when the mouse was moved (goes from 0.02ms to around 8ms). Strangely enough, rotating the view by dragging with the mouse, almost does not increase the event traversal time (goes to 0.04ms). Has anyone else noticed this behavior and have an idea on whats going on?

[osg-users] Height Above Terrain for PagedLOD node converted from Proxy node
Hi, I've just converted some OpenFlight files to Paged ive by replacing the Proxy nodes to PagedLOD nodes in the master flight, thanks to Brian Hill. Can anyone advise me on how do I do a terrain height query with this new pagedLOD database?

Some movies are apparantly encoded in BGRA instead of the more traditional RGBA format. My first thought is that the OpenGL header file you're including doesn't support the GL_EXT_bgra extension. See this webpage for some more details. It would be interesting to know what OpenGL extensions are not supported when compiling against a MinGW GL/gl.h http://www.opengl.org/resources/features/OGLextensions/ I believe you could work around this with a software patch by swapping the blue and red channels on the entire buffer. -- Philip Lowman ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

As far as I remember I had this error, too.
It was somehow related to the windows.h. Try to include it later.

The converter in VS 9 converted all of the projects without fuss, and I was able to get it all compiling and running pretty easily. Unfortunately, I am seeing this 30% drop in framerate :(.

Re: [osg-users] Problems with loading model in OSG 2.2
I still can't solve this problem:
Error: [screen #0] ChooseMatchingPixelFormat() - Unable to choose the
requested pixel format
I just loaded a simple model but the program run really slowly (in
debug mode), it's better in release mode.
I used osg1.2 and it run so fast, even in debug mode.
Please support me with this problem, is it because of that error?
My code is simply like this:
#include osg/PositionAttitudeTransform
#include osg/Group
#include osg/Node
#include osgDB/ReadFile
#include osgViewer/Viewer

{
osg::ref_ptrosg::Node m_node = new osg::Node();

[osg-users] Some yes/no questions about VBOs
Dear All, I have a few VBO related questions; a few quick yes/no answers would be much appreciated to stop me going down dead ends... I attach a vertex array, texcoord array and normal array to a Drawable, which is using VBOs. From the code, I can see that calling dirty() on any of the arrays dirties the entire VBO. 1) I can't quite understand all of the BufferObject code, but just to check, it looks like all three arrays are dumped into one large contiguous buffer (i.e. one single bufferID). Is that correct?

Re: [osg-users] mouse/viewport issues with CompositeViewer
Hi Bob, I am wondering about the status of this bug/fix (below) that I originally saw discussed back in late Feb. by Paul M., Jean-Sebastien and Robert, and again in late May, with no firm resolution. I am using OSG 2.4 and appear to be experiencing this same problem using CompositeViewer and slave cameras. Is the only current option to drop down to osgViewer::Viewer, or will doing a current SVN checkout resolve it? This fix was committed and is part of OSG 2.4. Perhaps you're seeing something different, or perhaps it's come back to haunt us? :-) Try this: osgpick --CompositeViewer Does that exhibit the same symptoms as the ones you see? This was the test bed for the patch I submitted. If the patch was not applied, trying to rotate the fountain when the composite viewer was on two screens (hence using slave cameras) gave very little movement. For me at least, that example shows me that it's fixed.

Re: [osg-users] Performance hit caused by porting from VS 7.1 to VS 9
Hi Robert, Do the express editions do full optimizations? I recall previously MS used to cap the optimization on the give away versions of VS. Nope, since 2005 express (8.0 express) it's the full optimizing compiler that's included. Rick said he converted the projects for his app from VS7.1 projects, maybe that causes some options to be set to non-optimal values in the resulting projects...

Re: [osg-users] 144 errors in gl.h (resend with clean text)
Bonjour Cédrik, everythings is ok, but now I try to create my own class to manage scene ressources and visual studio dislike this. It seems that I've not linked everythings correctly. You need to add WIN32 to the defines in your project. In Visual Studio, right-click on your project, go to C/C++, Preprocessor, and in the Preprocessor Definitions field add WIN32 for both debug and release configurations. While you're at it, also add _DEBUG for the debug configuration and NDEBUG for the release configuration... For some reason the default VS projects have no preprocessor definitions, even though these, at least, should almost always be used...

[osg-users] VPB and how it generates terrain
Hello Robert, We currently have a student doing a masters project at our company, and his job will be to improve the terrain algorithms in the Vortex toolkit (both for physical simulation and graphical representation). One aspect is generating terrain from a height field, which is what VPB does. Unfortunately, since we need to support dynamic terrain/height fields, and since we also need to do collision detection against it, we cannot use VPB directly and will have to re-do much of the work that is already in VPB. I was wondering if you had any pointers to what strategies are used to generate the terrain. Any articles/papers? Both the actual geometry generation and the LOD strategies are of interest. The code is available for study but we're really looking for some high-level overviews of how it does its work and why those given tradeoffs were chosen. Any information you provide would be helpful.

Hi Virginia, There is not much I can do without seeing the problem first hand. Is it possible to recreate it by modifying the existing osgviewerQT example? If so, could do this to effectively create a unit test for this particular usage case. Another possible route with solving this type of usage case might be to explicitly pass in the parent window when creating the graphics context, but leave it to the OSG itself to create the windows rather that QT. I haven't personally tried this, but it should be possible, even if it requires a few tweaks to the OSG itself to enable it. Robert. On Wed, Jul 2, 2008 at 3:22 PM, Virginia Holmstrom [EMAIL PROTECTED] wrote: Hello I have been having problems with the destruction of my ViewerQT window and I was wondering if anyone could shed some light on the issue. I am seeing corruption in one view when another view is deleted (screen shot attached). We are using OSG 2.4 and Qt 3.3.3 on WindowsXP and Linux. Problems are reproducible on both platforms. We are required to permit muliple views into the same scene, each in its own window with its own navigation. The user may open one or more views, close views at anytime, and open new ones. We have a set up similar to the osgViewerQT example shipped with osg, where our ViewerQT inherits from both osgViewer::Viewer and the AdapterWidget. We actually flipped the inheritance order from the example, so that ours looks like this: ViewerQT : public AdapterWidget, public osgViewer::Viewer due to compilation problems with the Qt moc'ing the other way around. Note we are using QGLWidget, not QOSGWidget, and we use multiple ViewerQts instead of CompositeViewer due to problems discussed in thread http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2007-December/005676.html. Hence our use of multiple ViewerQts is also similar to Enrique Parodi's implementation he provided in that thread. We store a ref_ptr to the root node of our scene external to the ViewerQts. osg::ref_ptr osg::Group _osgScene; This ref_ptr persists as views are opened and closed and is only released when the application closes. Each time a ViewerQT is created we pass it the scene using setSceneData. All ViewerQts get the same root scene node. We started having a problem when we set the Qt::WDestructiveClose flag in our AdapterWidget, which triggers the following destructors to be called in this order on close: ViewerQT osgViewer::Viewer osgViewer::View osg::View AdapterWidget We normally perform cleanup of our own classes in ViewerQT::~ViewerQT, however we see the corruption when the ViewerQT destructor is empty as well! The AdapterWidget destructor contains _gw-getEventQueue()-closeWindow(); The easiest way to reproduce the problem is to open multiple windows, then close the first window(view), triggering its destruction. Frequently the last window will be corrupted. I use corruption for lack of a better term. Geometry may disappear, textures may disappear, osgText may become blocks, while other parts of the scene are still visible in their original form. We've also had problems with the background stars flipping to an opaque dome. In the screen shot provided I closed the first window (hence blank space upper left) and immediatly as I did that portions of the scene disappeard from the last window (bottom right) and the text became blocks. If I subsequently open a new window the scene usually appears normal. I am not sure if I have a: memory problem? problem with the shared scene when ViewerQTs destruct? problem in the GraphicsWindowEmbedded? QT problem? ???

How do I set the Anistropy for all textures which are read in (using an OpenFlight file) to a particular value??

Re: [osg-users] ViewerQT destruction
Robert- I have modified AdapterWidget.cpp from the osgviewerQt example. Use with Osg 2.4, Qt 3.3.3. It is obviously much simplified from what I have but exhibits a similar problem. What I changed: 1. Created 3 ViewerQts instead of just 1 2. Added a destructor to ViewerQt 3. Added the Qt::WDestructiveClose flag to the AdapterWidget, which triggers the ViewerQt destructor to be called when the window is closed How to use: 1. osgViewerQTd.exe cow.osg 2. Mine pops up cascaded, cow in each window 3. Close a window (middle window works well for me) 4. Check remaining windows, cow will likely have disappeard from one of them 5. If this didn't work, try closing the other windows, or running again and closing the windows in a different order. Thank you so much, Virginia Hi Virginia, There is not much I can do without seeing the problem first hand. Is it possible to recreate it by modifying the existing osgviewerQT example? If so, could do this to effectively create a unit test for this particular usage case. Another possible route with solving this type of usage case might be to explicitly pass in the parent window when creating the graphics context, but leave it to the OSG itself to create the windows rather that QT. I haven't personally tried this, but it should be possible, even if it requires a few tweaks to the OSG itself to enable it. Robert. On Wed, Jul 2, 2008 at 3:22 PM, Virginia Holmstrom [EMAIL PROTECTED] wrote: Hello I have been having problems with the destruction of my ViewerQT window and I was wondering if anyone could shed some light on the issue. I am seeing corruption in one view when another view is deleted (screen shot attached). We are using OSG 2.4 and Qt 3.3.3 on WindowsXP and Linux. Problems are reproducible on both platforms. We are required to permit muliple views into the same scene, each in its own window with its own navigation. The user may open one or more views, close views at anytime, and open new ones. We have a set up similar to the osgViewerQT example shipped with osg, where our ViewerQT inherits from both osgViewer::Viewer and the AdapterWidget. We actually flipped the inheritance order from the example, so that ours looks like this: ViewerQT : public AdapterWidget, public osgViewer::Viewer due to compilation problems with the Qt moc'ing the other way around. Note we are using QGLWidget, not QOSGWidget, and we use multiple ViewerQts instead of CompositeViewer due to problems discussed in thread http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2007-December/005676.html. Hence our use of multiple ViewerQts is also similar to Enrique Parodi's implementation he provided in that thread. We store a ref_ptr to the root node of our scene external to the ViewerQts. osg::ref_ptr osg::Group _osgScene; This ref_ptr persists as views are opened and closed and is only released when the application closes. Each time a ViewerQT is created we pass it the scene using setSceneData. All ViewerQts get the same root scene node. We started having a problem when we set the Qt::WDestructiveClose flag in our AdapterWidget, which triggers the following destructors to be called in this order on close: ViewerQT osgViewer::Viewer osgViewer::View osg::View AdapterWidget We normally perform cleanup of our own classes in ViewerQT::~ViewerQT, however we see the corruption when the ViewerQT destructor is empty as well! The AdapterWidget destructor contains _gw-getEventQueue()-closeWindow(); The easiest way to reproduce the problem is to open multiple windows, then close the first window(view), triggering its destruction. Frequently the last window will be corrupted. I use corruption for lack of a better term. Geometry may disappear, textures may disappear, osgText may become blocks, while other parts of the scene are still visible in their original form. We've also had problems with the background stars flipping to an opaque dome. In the screen shot provided I closed the first window (hence blank space upper left) and immediatly as I did that portions of the scene disappeard from the last window (bottom right) and the text became blocks. If I subsequently open a new window the scene usually appears normal. I am not sure if I have a: memory problem? problem with the shared scene when ViewerQTs destruct? problem in the GraphicsWindowEmbedded? QT problem? ??? I am very open to suggestions. ;-) Thank you so much, Virginia ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph. org /* OpenSceneGraph example, osganimate. * * Permission is hereby granted, free of charge, to any person obtaining a copy * of this software and associated documentation files (the Software), to deal * in the Software without restriction, including without limitation

Re: [osg-users] VPB/osgdem and transparent textures
Hi Robert, I admit one of the main reason I'm after blending / transparency in my terrain is that I'm using source imagery that is reprojected from geographic to UTM coordinates. The reprojection results in a slight warping of the texture, leaving irregular NODATA bands around the sides. When osgdem creates the terrain, these NODATA regions around the border are colored opaque black. I'd like to, in essence, slice off this black, NODATA border. I think VPB by default alpha's these regions out, but this displays only when I add GL_BLEND to the resulting .osg files. Another, slightly less important reason for me wanting to have transparency enabled on the terrain is that I'd like to make the bodies of water on my terrain to have a very simple see-through or reflection type of effect. I say simple because all it would take is probably for the bodies of water to be transparent in the source texture imagery. As you can tell, I am still very new to OSG-- but willing to learn. I really appreciate your response.

Re: [osg-users] OSG thread profiling results are in!!
Hi Robert, I got the stats handler working on our scene and displaying. I am not sure I understand what the different numbers mean and how I might work with them. I can see the optimization effort is a big deal. I know it is beyond the scope of this group. Are there any resources out there to look at? I have finished the work you had already mentioned, like using png rather than bmp everywhere. We are also working on making sure our images are as small as possible. We are also going to work on using LOD. Since we are in space and most ships are far away, we are sure we can make a big jump there. I used osgUtil::Optimizer and that game me a few more frames. What are some other suggestions? We are using some particle effects pretty heavily, and we noticed (using filemon) that the smoke image file is being read over and over again, many times (perhaps once per frame). Is this possible? We are going to look into that next. Maybe we can cache the single image (state set)?

What would be great is to have a big balanced scene that can put OSG Viewer to the test in a way where it puts equal intense stress on update, culling, and draw dispatch. What I'd hope to see is the draw dispatch be on a separate thread, where that thread showed mostly I/O activity, and the cpu activity on other threads. The osgViewer::StatsHandler will display update, event, cull, draw dispatch on all systems and draw GPU stats. The GPU stats require an OpenGL extension that I've only seen Nvidia implement so far, so you won't see this stats printed out on all systems. Also record a camera path/game sequence that you can use for benchmarking so that every run the app does the same thing, then you'll be able to study the effects that changes you make have on final performance. You'll also be able to study the above stats to where the problems occur in your scene.

[osg-users] new Optimizer improvement rocks
This improvement to sharing duplicate state in Optimizer has boosted my app's performance 10-20% on my various computers at work. Nice job, and thanks. I'm running a pretty complex .flt city model with lots of textures for all the buildings and cars. It also loads lots of external models. I wonder if others are seeing this much improvement. revision 8513: Changed the Optimizer::StateVisitor so that it can individually decide whether to optimize away duplicate state with dynamic, static and unspecified DataVarience. By default the code now optimizes away duplicate state with either static and unspecied state, previously it was just handling static state. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] VPB and how it generates terrain
There's an article entitled On-the-sphere block-based 3D terrain rendering using a wavelet-encoded terrain database for SVS by Greg Baxes and Tim Linger of TerraMetrics Inc. The article gives a high level view of their algorithm which I believe is the one or similar to the one used in Earth viewers like Google Earth and NASA World Wind for terrain rendering on a sphere... -Shayne -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jean-Sébastien Guay Sent: Wednesday, July 02, 2008 8:12 AM To: OpenSceneGraph Users Subject: [osg-users] VPB and how it generates terrain Hello Robert, We currently have a student doing a masters project at our company, and his job will be to improve the terrain algorithms in the Vortex toolkit (both for physical simulation and graphical representation). One aspect is generating terrain from a height field, which is what VPB does. Unfortunately, since we need to support dynamic terrain/height fields, and since we also need to do collision detection against it, we cannot use VPB directly and will have to re-do much of the work that is already in VPB. I was wondering if you had any pointers to what strategies are used to generate the terrain. Any articles/papers? Both the actual geometry generation and the LOD strategies are of interest. The code is available for study but we're really looking for some high-level overviews of how it does its work and why those given tradeoffs were chosen. Any information you provide would be helpful.

[osg-users] Converting model to screen coordinates
Hello, I'm trying to convert from model coordinates to screen coordinates with the following code: // Compute the model to screen transformation matrix osgUtil::SceneView* sv = m_sHandler-getSceneView(); osg::Matrix modelView = sv-getViewMatrix(); osg::Matrix projection = sv-getProjectionMatrix(); osg::Matrix window = sv-getViewport()-computeWindowMatrix(); osg::Matrix MVPW = modelView * projection * window; // convert a point in model coordinates to screen coordinates osg::Vec3 screenPoint = modelPoint * MVPW; The resulting screen coordinate point is correct in the x-dimension, but scaled down incorrectly in the y-dimension. The only point that is correct is the center point of the model. Am I missing a matrix somewhere? or does anyone have an alternate method of doing this?

Re: [osg-users] Bump mapping question
Hi Judie A rarer than hens teeth content question :) We just use a standard 24 bit normal maps, for which we use a few different tools, the least sophisticated or useful of which is the Nvidia tool, works but is ugly and output is average. Xnormal www.*xnormal*.net and Crazybump http://www.crazybump.com/ are the primary ones, of which crazy bump is outstanding for extracting normal maps and displacement maps from images Xnormal is great for extracting normal maps from high rez models. X normal is free, Crazybump is not. cheers Jon Judie wrote: fyi...

[osg-users] How to control RTT camera sometimes work and sometimes don't work
Hi, I want to let the RTT camera render the scene only when the scene changed, are there any callback mechanism that I can control the RTT camera when it has to update the texture and when it should stop working? If I make the RTT camera stop working, will the textures it renders be destroyed instantly? If the texture will be destroyed, how can I save the data of MRT to images for I will use these data every frame in the later pass? Are there any method that make the MRT data avoid being destroyed instead of copy those data to images?

Re: [osg-users] Performance hit caused by porting from VS 7.1 to VS9
Thanks for this info... I checked the projects by hand and sure enough all the optimization settings were incorrect. I simply fixed them and viola back in business!!

Thanks again for all the fantastic forum support. We have been using VS 7.1 for all of our work so far, but since we were missing a well build freetype library, I figured it was time to make the jump there as well. I downloaded VS 9 express and ran CMake to build OSG. All built just fine. The converter in VS 9 converted all of the projects without fuss, and I was able to get it all compiling and running pretty easily. Unfortunately, I am seeing this 30% drop in framerate :(. I was seeing about 28-30 fps (yes, I know, I have some scene optimizing to do) with the VS 7.1 build, which dropped to 20-21 fps using VS 9 express. Has anyone seen anything like that before? Am I missing some setting somewhere? Perhaps the converter in VS 9 does not like me? Any ideas? -- Thanks Rick Check us out at http://fringe-online.com/ -- ___ 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
