Re: [osg-users] Getting the window handle generically.
Hi David, You can get the platform specific window handles by casing the osgViewer::GraphicsWindow to GraphicsWindowWin32/X11/Carbon and then getting the handle from them.

Re: [osg-users] Some OSG examples doesn't work !
Hi Stephane, are you running with any of the bundled OSG distro of 3rd-party libs? Either http://www.mew.cx/osg/ or http://www.openscenegraph.org/downloads/dependencies/ I think these are only built Release for WIN32 and your mileage may vary depending on the moon phase as to whether you may get a mismatch of Debug/Release. Also regarding these binaries they are built with either MSVS 2003 or MSVS 2005 SP1 and may not be binary compatible with MSVS 2008. If you have all the 3rd-party and entire source built using 2008 then apologies for barking up the wrong tree ;) Cheers, Colin.

[osg-users] Finding Textures to be drawn
Hi Robert, I need to update many textures every frame, but ideally I'd only update those that will actually be drawn. So after I've called SceneView::cull() what's the best way to identify all textures to be drawn? The maximum size at which the textures will be drawn is also important, so how can I get the bounding box and projection and modelview matrices for each Drawable to be drawn with that texture?

Template reflection is not supported in osgIntrospection. You have to reflect each class create with a template. Done automatically by genWrapper when it found a template instantiation. Take a look to src/osgWrapper/osg/Array, each osg::Vec2, osg::Vec2s, osg::Vec3 ... are reflected. And by the way, I noticed that (with the SVN version of the genwrapper at least) it is not possible to use the option -p to generate VisualStudio project files.

OSG is bind in many other language than C++ with osgIntrospection and I don't know how this bind does to use operator. Perhaps simply not use operator at all.

[osg-users] osgText quality
Hi, have anybody any hints about which parameters values give the best quality with osgText?

Hi FYI I guess JP was talking about this thread http://thread.gmane.org/gmane.comp.graphics.openscenegraph.user/9932/focus=9937 Using two equal values for the resolution worked for me too. You have to try various values because some rounding is performed in background and you won't necessarily notice any change if you increment them by one, for instance.

Re: [osg-users] Integrationg OpenALpp
Hi, I seem to remember something similar myself under Ubuntu. I was using the autotools configure script and it needed PKG_CONFIG_PATH to include the path to the openscenegraph.pc file This resides in packaging/pkgconfig relative to the OpenSceneGraph source root It may require others too, for the other dependencies like OpenAL, vorbis etc. Take a look at the man page for pkg-config to get the idea. So, you would issue a command like so: export PKG_CONFIG_PATH=/path/to/OpenSceneGraph/packaging/pkgconfig:/path/to/OpenAL/admin/pkgconfig: ... before running configure Looking at my OpenSceneGraph installation, it doesn't seem to copy the pc file when it installs the headers and libraries, so that might cause some confusion. Hope this helps, -Tony ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Finding Textures to be drawn
HI Michael, This is no trivial tasks. You'll need to grapple with the internals of RenderStage/RenderBin/RenderLeaves that the cull traversal populates and the draw traversals reads. I'm afraid I don't have the time to walk you through all this. There are probably other ways to tackle this task via custom cull callbacks or nodes that decorate your scene and have knowledge about your geometry, textures. Robert.

[osg-users] how to manage different model types
Hi all, I have a general question about model orientation. If I get several models from several sources (flt, 3ds etc...). Their original orientation may be different depending on how they have been built. Is there a way to convert them automatically to follow a terrain orientation for ex? For instance, I'm working today with a plane and a copter. If I place these two models at origin one is pointing head to north and the second is pointing head to east. Meaning that the views, position and transformations for plane and copter have to be different. Is it possible to make it generic (at least linked to a terrain)?

Re: [osg-users] how to manage different model types
Probably the easiest (and perhaps only sensible) way is to use osgconv to adjust the model transformations before loading them into your app, and not to address the issue at all with any kind of code. Its really up to the asset to encode this information consistently within itself... osgconv -h ...will tell you almost everything you ever wanted to know. :) On Thu, 2007-12-06 at 17:13 +0100, Stephane DUGUET wrote: Hi all, I have a general question about model orientation.

I use a small XML configuration to tie a model to some additional parameters. For instance, when I request a tank model, the XML configuration includes the model file to load, along with a top-level rotation, translation, and scale for that model. When loading the model, I add the model node as a child of a matrix transformation node if the configuration says that a rotation, translation, or scale is required. Having such a configuration file allows a client to add their own models without needing special tools or an expert to preprocess the model.

I believe newer versions of it even do multitexturing and shaders, but I have only used older versions of Creator that can only handle a single texture. Creator saves .flt which maps very cleanly to OSG's scenegraph structure. Artsy modelers like 3ds max are powerful and let you do lots of pretty stuff such as making very organic (curvy) models and use really complex material properties, but they don't map as well to OSG's structure. You'll need to rely on an exporter like OSGexp to get your models into OSG. I have used OSGexp successfully, although sometimes I needed to hack it a bit to get exactly what I wanted. For an airport I'm guessing you could get the job done faster with Creator, but there's no simple answer to your question. It's best to do a test model in each package and get it loading in OSG. Depending on the types of models you want, one modeler might be a whole lot better than the other. - Terry Message: 2 Date: Thu, 6 Dec 2007 09:59:15 +0800 From: Loong Hin [EMAIL PROTECTED] Subject: [osg-users] Creator vs 3D Studo Max To: osg-users@lists.openscenegraph.org Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=Windows-1252 Hi, I've a flight simulator project running on OSG 2.2 whereby we need to model a geo-specific airport.

[osg-users] osgDB::Archive - is there a way to set the master filename?
When generating OSGA archives, I need to write the master file last. However the OSGA plugin seems to automatically choose the first file added as the master. I am able to work around this by first writing an empty group node as master.ive, and then writing the real master file at the end (with the same filename) ... but is there a more elegant solution?

Re: [osg-users] Taking an image of an intermediate node.
Hi, i'm not completely sure, but i think that shot-allocateImage(width, height, 24, GL_RGB, GL_UNSIGNED_BYTE) must be shot-allocateImage(width, height, 1, GL_RGB, GL_UNSIGNED_BYTE)... i.e. Changing the 24 by the 1. The third component is the 3rd dimension of the image. Also, you need not to call allocateImage at all, i think it is done by OSG, and will set the correct format and size. The initialization of the camera seems ok, perhaps your error is setting the view or projection matrix? I would first test that focusing the camera to a known place instead of calculating the node position. Hope this helps.

[osg-users] Using osgSim::OverlayNode
My application utilizes a large terrain database, and it relies heavily on osgSim::OverlayNode. Originally, I used OBJECT_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY for the overlay technique. With this technique, my application works properly; however, it is very resource intensive, and the overlay shapes are noticeably pixelated. Ideally, I would like to switch to using VIEW_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY as the overlay technique. With this technique, the overlay shapes look much better (no noticeable pixelation). Additionally, this technique significantly reduces the memory footprint and increases the frame rate of my application. Unfortunately, my application does not work properly. It appears that many of the overlay shapes are getting partially or completely clipped, which results in an incomplete overlay. VIEW_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY appears to be highly-dependent on the value of the overlay base height. This is a problem, as the terrain elevation of my database is variable, and I am not able to find a value that works well from all viewing angles. What can I do to allow the VIEW_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY technique to work better in my environment?

Re: [osg-users] OpenFlight Continuation Record support
Continuation records are great when writing out FLT files but a * when
reading them back in - I had to abandon upgrading some proprietary FLT
reader code because it required a complete rewrite of the FLT file decoder
just to support this one new record type.
The FLT file record structure requires every record to include a known
length not exceeding 1024 bytes, so all the decoder had to do was read the
correct number of bytes from the file into a 1024 byte buffer and then start
processing the record. The existing FLT record structure was retained with
no hint to give advance warning the current record has a following
continuation record.
The only way I saw to support this record type was to strip out the entire
file reading mechanism and craft/hack/jam in a new layer that assembled
internal records from one or more FLT file records, and then sent each
internal record into the decoder core. Unfortunately this broke the entire
design which was based on a long winded while( !eof() ) { readrecord();
processrecord() } architecture.
