Paul, It looks like the osgviewerWX plugin is pulling in Carbon stuff and/or Quicktime stuff for 64-bit. I imagine it's actually in the WXWidgets library itself, not necessarily the example code. I'm sorry I don't have the error in front of me, and it would take some time to generate.

Hi Ahmed, On Tue, Aug 5, 2008 at 9:38 AM, Ahmed Nawar [EMAIL PROTECTED] wrote: I read in 2.6 Updates include this New database optimizer that is able to remove static transforms by duplicating shared geometries What I'm referring to is the new addition to the osgUtil::Optimizer is of osgUtil::Optimizer::FlattenStaticTransformsDuplicatingSharedSubgraphsVisitor. You can switch it on by or'ing in osgUtil::Optimizer::FLATTEN_STATIC_TRANSFORMS_DUPLICATING_SHARED_SUBGRAPHS bit when calling optimizer.optimizer(node,options); Or just constrcut the visitor yourself and apply it directly to your own subgraphs. And I want to ask what is best for performance. Duplicate geometries (or) Shared geometries and transform them. There is no straight answer to this. Some scenes will benefit from duplicating the geometries and removal of the transforms, others will perform less well. If you are CPU rather GPU limited then going the duplicated route is likely to help, while if your are GPU limited rather the CPU then sharing subgraphs and using transform to place the instances will be better. The easiest way to find out whether your databases will benefit is to go ahead an optimize them and then benchmark the different types of optimizations. The way I do such tests is use env vars (the below assumes you are using the bash shell) export OSG_OPTIMIZER=OFF osgconv mydatabase.flt off.ive export OSG_OPTIMIZER=DEFAULT osgconv mydatabase.flt default.ive export OSG_OPTIMIZER=DEFAULT FLATTEN_STATIC_TRANSFORMS_DUPLICATING_SHARED_SUBGRAPHS osgconv mydatabase.flt duplicate.ive The record an animation path with osgviewer (press 'z' to start and stop recording the path) then run the benchmarking: osgviewer off.ive --path saved_animation.path osgviewer default.ive --path saved_animation.path osgviewer duplicate.ive --path saved_animation.path I'll typically run the tests with vsync on and off. Run it with vysnc on to find out whether you ever drop frames which is the critical part to our final apps, then with vsync off to get a relative performance profile between the tests. Do the tests several times to make sure that cache isn't playing tricks on your performance results.

[osg-users] Calculate BoundingBox
Hi,
I've made a NodeVisitor that should calculate the bounding box of a Node.
Here is the apply function:
void ComputeBoundingBox::apply(osg::Geode node)
{
for(unsigned int i = 0; i node.getNumDrawables(); ++i)
{
m_bb.expandBy(node.getDrawable(i)-getBound());
}
traverse(node);
}
Where m_bb is an osg::BoundingBox.
This works perfectly if the scene graph does not contain any transforms.
If the scene graph contains transform, the geometry is not transformed
prior the expandBy function. The result of this, is of course a bad
bounding box.
What is the best way to calculate a bounding box?

Re: [osg-users] OSX X11 build
This change only fixes libosgviewer for X11 (32- and 64-bit). It does not fix the two remaining issues: the osgviewerWX example and the osgdb_qt Quicktime plugin. Neither compile with 64-bit. So, out of the box, the 64-bit build on OSX is still broken.

After updating to the latest svn, I noticed that 64-bit compilation is enabled by default on OSX (See line 532 of the main CMakeLists.txt). This is still broken. The default should be for 32-bit compilations so the build is not broken out of the box. We just need to remove ppc64 and x86_64 from that build.

[osg-users] vpb build_master.source --radius-equator
Hi, when setting the values --radius-equator and --radius-polar, the values in the ellipsoidmodel are set in vpb, but they are not written to the build_master.source file. So, when doing a distributed build, these options get discarded when osgdem reads the .source file. I am still trying to get my head around how the parsing of the .source file works. Would a fix be as easy as adding the options to the BuildOptions and BuildOptionsIO files? I need to build a DB with specific radii.

Re: [osg-users] Using SSE within OSG
I would like to take a moment to show a snap shot of how these optimizations have impacted our game. To interpret the data, they show frames per second where the first column keeps an average of the lowest times, the middle keeps the overall average, and the right keeps track for the highest times. We do at least 3 runs to get a good solid average. Here is the fps without any of the SSE optimizations: Framerates: (23.3, 41.3, 54.2) Framerates: (27.5, 41.9, 50.4) Framerates: (30.6, 41.8, 53.3) AVERAGE:(27.1, 41.7, 52.6) Here is my submissions with SSE optimizations Framerates: (30.2, 48.7, 58.1) Framerates: (30.9, 49.6, 60.5) Framerates: (36.8, 50.0, 60.5) AVERAGE:(32.6, 49.4, 59.7) Here is a combination of my Submission and Mathias submission VS 9 (current) ..\Game Scripts\Miramar_001.lua -perf 0 60 0 -stats 10 60 VS9_Perf.txt Framerates: (40.9, 53.2, 65.6) Framerates: (34.5, 50.3, 60.9) Framerates: (39.5, 49.9, 63.2) AVERAGE:(38.3, 51.1, 63.2) So basically in this test, both of our optimizations have yielded a solid +10 fps for this machine. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Users that know what they are doing can easily add it back in through cmake and use the other workarounds I already posted. -Eric On Tue, Aug 5, 2008 at 10:45 AM, Eric Sokolowsky [EMAIL PROTECTED] wrote: On Tue, Aug 5, 2008 at 10:44 AM, Eric Sokolowsky [EMAIL PROTECTED] wrote: This change only fixes libosgviewer for X11 (32- and 64-bit). It does not fix the two remaining issues: the osgviewerWX example and the osgdb_qt Quicktime plugin. Neither compile with 64-bit. So, out of the box, the 64-bit build on OSX is still broken. However, another bug (which I have deliberately not fixed yet) keeps the default to 32-bit compilation, so things are not broken out-of-the-box. So here are the steps to take to compile 64-bit on OSX: Add ppc64 and/or x86_64 to CMAKE_OSX_ARCHITECTURES Generate the Xcode project Remove osgdb_qt and osgviewerWX from the list of targets within Xcode Build Doing this will compile, but images such as tiff, jpeg, gif, and png will not be supported. Note that this is only for 64-bit apps. 32-bit apps seem to work just fine when compiled against X11 or Carbon. -Eric ___ 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 ___ 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 ___ 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

Hi All, Over the last hours I have merged a change to Notify.cpp from me, and two CMakeLists.txt changes for OSX build from Eric Sokolowski, I'm not expecting fallout from these merges but it'll need testing... So... pretty please, could users do a svn update/checkout of the OpenSceneGraph-2.6 branch. I'll wait another couple of hours for feedback then if there is no reported problems go ahead and tag 2.6.0 this evening. Thanks for your help in testing ;-) Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] using shaders to find fthe maximum value in a texture
Do you need the maximum value over all texture elements? If yes, then you just have to compute a mipmap with max as combining operation. In the last level, where only one pixel left, you will get the maximum value. It is pretty straight forward to implement such an algorithm. Either any GPGPU approach can help you, or if you use osg, then take a look into osgPPU's hdr example.

[osg-users] View Rendering Order
Is there a means to control (change) the rendering order of individual Views within a CompositeViewer (e.g., to ensure that inset views appears on top of others or if two view areas are moved and overlap, to specify which one should be on top). The addView does a push_back() into the Views vector. Once all the Views have been added, the application I'm working on may need to then change the order around. Even if I remove all Views and re-add them in the order I want (even prior to the first rendering), the rendering still seems to follow the order of the original addView calls. I found that I can swap the ordering of 2 views using the View Camera's PRE_RENDER or POST_RENDER setting (seems like this is the wrong way to do it). When I have more than 2 views to reorder, I tried using the _RenderOrderNum integer, but alas, it didn't help. I'm assuming (hoping) there is a method for doing this which I'm not seeing?

Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org OpenSceneGraph 2.6 Release Notes for Macintosh OSX There are several ways to compile OpenSceneGraph under OSX. The recommended way is to use CMake 2.6 to generate Xcode projects, then use Xcode to build the library. The default project will be able to build Debug or Release libraries, examples, and sample applications. Here are some key settings to consider when using CMake: BUILD_OSG_EXAMPLES - By default this is turned off. Turn this setting on to compile many great example programs. CMAKE_OSX_ARCHITECTURES - Xcode can create applications, executables, libraries, and frameworks that can be run on more than one architecture. Use this setting to indicate the architectures on which to build OSG. Possibilities include ppc, ppc64, i386, and x86_64. Building OSG using either of the 64-bit options (ppc64 and x86_64) has its own caveats below. OSG_BUILD_APPLICATION_BUNDLES - Normally only executable binaries are created for the examples and sample applications. Turn this option on if you want to create real OSX .app bundles. There are caveats to creating .app bundles, see below. OSG_WINDOWING_SYSTEM - You have the choice to use Carbon or X11 when building applications on OSX. Under Leopard and later, X11 applications, when started, will automatically launch X11 when needed. However, full-screen X11 applications will still show the menu bar at the top of the screen. Since many parts of the Carbon user interface are not 64-bit, X11 is the only supported option for OSX applications compiled for ppc64 or x86_64. There is an Xcode directory in the base of the OSG software distribution, but its future is limited, and will be discontinued once the CMake project generator completely implements its functionality. APPLICATION BUNDLES (.app bundles) The example programs when built as application bundles only contain the executable file. They do not contain the dependent libraries as would a normal bundle, so they are not generally portable to other machines. They also do not know where to find plugins. An environmental variable OSG_LIBRARY_PATH may be set to point to the location where the plugin .so files are located. OSG_FILE_PATH may be set to point to the location where data files are located. Setting OSG_FILE_PATH to the OpenSceneGraph-Data directory is very useful when testing OSG by running the example programs. Many of the example programs use command-line arguments. When double-clicking on an application (or using the equivalent open command on the command line) only those examples and applications that do not require command-line arguments will successfully run. The executable file within the .app bundle can be run from the command-line if command-line arguments are needed. 64-BIT APPLICATION SUPPORT OpenSceneGraph will not compile successfully OSG_WINDOWING_SYSTEM is Carbon and either x86_64 or ppc64 is selected under CMAKE_OSX_ARCHITECTURES. A version of the osgviewer library written in Cocoa is needed. However, OSG may be compiled under 64-bits if the X11 windowing system is selected. However, Two parts of the OSG default distribution will not work with 64-bit X11: the osgviewerWX example program and the osgdb_qt (Quicktime) plugin. These must be removed from the Xcode project after Cmake generates it in order to compile with 64-bit architectures. The lack of the latter means that images such as jpeg, tiff, png, and gif will not work, nor will animations dependent on Quicktime. A new ImageIO-based plugin is being developed to handle the still images, and a QTKit plugin will need to be developed to handle animations.
