Re: [osg-users] Method for Converting FLT files to use DDS
Hi Karl. It's a long time since I've look at the contents of FLT files, but I vaguely remember them being organised as records, where each record contains a type-id and a record length. If FLT format hasn't changed dramatically, then it should be possible (in C/C++) to write a program that can examine each record in turn looking for texture records with a filename ending .rgb\0 or .rgba\0. If you keep the filename part of your textures consistent, and just change the extension when you convert them, then you're simply changing .rgb\0 for .dds\0 in the FLT files. See http://www.presagis.com/files/standards/OpenFlight16.4.pdf However, I'd be tempted to try a quick and dirty test first by ignoring the FLT specification. Instead, treat the files as binary and search for .rgb\0 and replace with .dds\0. Then test the files just in case .rgb\0 caught some binary data. I wrote a simple FLT parser about 12 years ago in C for OpenGL which was able to pick out geometry with textures, so I think all of this is do-able without using OSG and without the FLT API. If I remember my *nix correctly then you can see the occurencies of rgb with... cat file.FLT | strings | grep -i rgb Good luck, Gary. -- Message: 6 Date: Fri, 25 Jan 2013 07:54:47 -0500 From: Cary, Karl A. karl.a.c...@saic.com To: OpenSceneGraph Users osg-users@lists.openscenegraph.org Subject: [osg-users] Method for Converting FLT files to use DDS Textures Message-ID: a7dd40477b3bac4a8c606c67b53b70a307404...@0015-its-exmb12.us.saic.com Content-Type: text/plain; charset=us-ascii This isn't a direct OSG question, but one I was hoping people on this list might be able to help out with. We have several thousand FLT files that use rgbs as textures. Unfortunately we can't convert these to ive or osgb files as they are shared with another application that is not made in OSG and only supports FLT files. However, both can support FLT files using DDS textures to allow for texture compression. Through testing we have shown a large improvement by doing this, so we want to go that route. The issue is how to convert all of these FLT files over. We can easily batch convert all of the textures, that is not a problem. The issue is updating the FLT files themselves to tell them to point to the dds texture instead of the rgb texture. Having someone manually open up each file and edit the texture names is VERY time consuming. Does anyone know of an easy way we could do this through scripting or a custom converter or something else? The files will stay named the same except for the .rgb will become .dds. Thanks in advance.

You'll need to pull this down from the genwrapper svn and build it locally. I've seen this error before when testing an earlier rc.

Re: [osg-users] NVidia Drivers Release 181.20
Hi Jeremy, Ryan. For info, I installed 181.22 on two Windows XP PCs with PNY 9800GTX's. One PC blue screened every night, and the other PC produced random noise on screen that looked like snow when panning around a commercial 3d application we use. Reverting to 181.20 solved both those problems. Gary. I don't know if this is pertinent information or not, but all of the games I play regularly (Bioshock, Fallout 3, Steam games, WOW) all were totally hosed on 181.20 with my GTX 280 card; graphical anomalies, weird crashes, you name it. I upgraded to 181.22 and the problems went away...

With the Quadro drivers ( on a Quadro 3450 ), I am not seeing any crashes, but I am seeing patches of the terrain either displaying a black texture or not rendering sections to the frame buffer. I even saw what looks like a point or two rendering at infinity. With the GeForce drivers ( on a GeForce 7600 GT ), I am seeing the terrain render fine, but randomly the graphics driver will popup a dialog indicating that the driver has performed an illegal operation and has requested that the application be terminated. There have been many reports related to driver instability for the GeForce cards related to this driver, so I expect that Nvidia is in the process of correcting this. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Robert. Thanks for your reply. I also suspect the drivers are causing some of the problems. Unfortunately, the exe's don't seem to want to run on other machines right now, so testing is going to be difficult. I'll try to compile on a different PC for testing next time.

Re: [osg-users] Please test OSG-2.8 in prep for 2.8.0-rc2
Hi Robert. OpenSceneGraph 2.8.0-rc1, Windows XP SP3, Vis Studio 2008. no errors, no warnings when compiling. There are some spelling errors/typos in the text output from various examples. I haven't had time to go through them all, but the ones I've found are listed in http://vr3.tees.ac.uk/osg280rc1/OSG280rc1SpellingErrors.txt osgShell.bat seems to be broken, I guess it's been moved up or down a directory level since the last time I tried it. I've uploaded a modified version to http://vr3.tees.ac.uk/osg280rc1/osgShell.bat which assumes that the data 3rdparty directories are both inside the OpenSceneGraph-x.x.x directory. osgAutoTransform seems to have a problem on a dualview display (2x 1280x1024 displays, NOT horizontal span), where the text seems to flicker (even when the camera isn't moving) and text randomly appears in random places across the screen. This is at its worst when the model is spread across the two screens. If I can find a way to screen grab this, I will - but no promises. osgGeometry... The yellow geometry remains stationary when the model is moved - is this correct ? See http://vr3.tees.ac.uk/osg280rc1/osg280rc1_osggeometry.jpg osgfxBrowser... The description text sits over the help text which looks untidy. See http://vr3.tees.ac.uk/osg280rc1/osg280rc1_osgfxbrowser.jpg osgKeyboard... When I press the Alt-Gr key, the display shows the Left-CTRL key as being pressed. osgPrecipitation... Looks good when the camera is static, but the precipitation moves in the opposite direction to the camera. The transition from a static camera to a moving camera creates an abrupt change in the precipitation which looks odd. osgShaders... Only the bottom row of models are shaded. Is this correct ? See http://vr3.tees.ac.uk/osg280rc1/osg280rc1_osgShaders.jpg osgviewer glsl_mandelbrot.osg crashes on exit with a NULL pointer reference. osgstereoimage produces a black screen, no visible model. osgScribe seems to incorrectly draw some of the back faces in wireframe. See http://vr3.tees.ac.uk/osg280rc1/osg280rc1_scribeExample.jpg and http://vr3.tees.ac.uk/osg280rc1/osg280rc1_scribeExampleCropped.jpg Finally, I vaguely remember the examples in a much earlier release all having a h hotkey for help, which showed how to save the scene, do a screen dump, etc. But none of the 2.8.0 examples seem to have this.

Re: [osg-users] osg-users Digest, Vol 15, Issue 70
Hi Paul. GenWrapper - no. I've just done a rebuild on OSG 2.6.0 to check, and didn't get a genwrapper error message. In 2.6.1, if I right click on the 'wrappers' target and select 'build', then genwrapper is found and runs normally -- no error. ... Did you build it from a genwrapper svn tree? Where did you put the executable after you built it? .. there's no way you could do an equivalent operation on 2.6 -- the 'wrappers' target didn't exist. The only difference at my side was that I downloaded 2.6.0 as a zip file from the OSG downloads page, but I got 2.6.1 from the svn url you specified. With both versions, I used the same batch of 3rd party libs, and I used VS's batch build to build everything. In general, you shouldn't need to build the 'wrappers' target, they should already be built and checked in. However, I see they are out of date on 2.6.1 That explains it, thanks Paul. I guess I wouldn't normally need genwrappers to compile OSG from source.

Re: [osg-users] 2.6.1 release
Hi Paul Sorry if that last email from me appeared a bit curt; No worries, you should see me when I fall out of bed on a morning or maybe you shouldn't :-) Attached is a batch file from Mike's svn tree that contains the package version numbers. Thanks, I wasn't aware of that. I was aware of some discussions on the mailing list regarding moving to different versions of 3rd party libs, but was unable to find the threads again. I'd also noticed that some of the 3rd party lib suppliers had withdrawn earlier versions - such as zlib 1.2.2 due to security issues. Do you have these same [compilation issues] when you build OSG v2.6 with these dependencies? LibTiff - yes. I was kind-of hoping that someone would have a config.h/makefile/whatever that would allow this to compile for OSG. ReaderWriterGif - yes. I think it's something to do with the function calling convention specified by libgif that doesn't work with OSG's calling convention. I couldn't see a way to fix this, but I'll take a look at the version of libgif used by Mike to see if that has the answer. GenWrapper - no. I've just done a rebuild on OSG 2.6.0 to check, and didn't get a genwrapper error message. Assuming you're on Windows... Many will warn you to not mix Release libs with Debug builds. However, I have found that you can mix them if the library meets two criteria: 1) the library interface must not use STL, and 2) don't mix the heap (don't alloc memory in Release code and free it in Debug, for example). LibTiff appears to meet these criteria, as far as I know, so you should be able to mix a Release libTiff with your Debug OSG. Cool - sounds like I can ignore that... for now. Thanks for your time.

Re: [osg-users] 2.6.1 release

I get errors with ReaderWriterGif (see below) which suggests that I've either got the wrong version, or I need to edit libgif's makefile to generate something that OSG can use. 3. A tool genwrapper is not recognised (see below for the full error message) I've written up what I've done to compile the 3rd party libs.
