Re: [osg-users] 64bit question
Hi, We have one 64bit setup in our company. It was not used for few months, but in the summer we we built couple osg releases using it. In that time, it was just a matter of selecting target 64 bit VS environment, when Cmake was run for the very first time in OSG directory. This selection is also available as a result of Cmake clear cache command. Clearing cache will bring target selection dialog again. Look carefully - you should be able to find 64 bit VS 2005 target. Maybe new cmake has 64 bit 2008 as well We ended up using VS 2005 Standard for 64 bit. VS 2005 Express does not offer 64 bit builds out of the box. Cmake won't also generate 64bit solution for VS 2005 Express. 64 bit in VS Express is theoretically possible with some hacking using Platform SDK compiler. But I attempted this path and give up due to some strange issues with compilation of stl and some predefined macros. Apparently Sdk compiler has to use Platform SDK headers and libs. It did not work well with Stl from VS 2005 express. So we ended up buing the cheapest commercial VS relases that alllowed to do this.

Re: [osg-users] Implementing a 3D GUI
Unfortunately, this will most likely not be open sourced due to the fact that I'm developing it for my employer. There is certainly an advantage to open sourcing it, I know, especially when it comes to fixing bugs and adding new features. However, my employer probably isn't ready to take that step forward yet. Incidentally, I was able to get the picker to work with my application. It took a little extra doing since the other 3rd party utility that I use, Delta3D, doesn't use the osgProducer class (still using OSG 1.2). My only bugs now that I have seen involve the mouse cursor flickering or the caret not showing (depending on the implementation used which gets complicated.) Unfortunately, those aren't OSG related; so asking for help with those is more than a bit off topic. -Brian On Thu Jan 24 13:27 , Jeremy Moles [EMAIL PROTECTED] sent: On Tue, 2008-01-22 at 12:00 -0500, Brian wrote: Hi, I am in the process of trying to create an interactive Macromedia Flash drawable.

Re: [osg-users] FBO and Antialiasing
3 options (there may be others) 1) Depending on the fidelity you need, render to a fbo some factor the desired size of your target then downsample in fragment shader (Alternatively, use generate mipmaps in the camera-attach() when you apply the target to your fbo and let the gpu downsample for you). This is the easiest to implement and produces adequate results in most cases. 2) Get yourself an NV80 based (i.e. 8800 or quadro 5600) graphics card and modify the osg framebuffer cpp file to use the nvidia multisample frame buffer extension. 3) Write your own custom multipass antialias routine for each object in your scene (do this if you have lots of development time and want full control over your scene) From: [EMAIL PROTECTED] on behalf of Stephane Lamoliatte Sent: Thu 1/24/2008 3:49 PM To: OpenSceneGraph Users Subject: [osg-users] FBO and Antialiasing Hi, I want to know if it is possible to render a scene to a frame buffer object with antialiasing (MSAA).

Re: [osg-users] wx with OSG canvas resize bug
Ok, so we dug deeper into the problem and found we have a problem with
intersection code. We call osgViewer::View::ComputeIntersections to
intersect an x, y position in screen coordinates to a grid in the scene to
produce a position in world space. osgViewer::View::ComputeIntersections is
reporting the wrong intersection points. The problem occurs when the
application is first started and after the wxGLCanvas window is resized. The
only way to fix the problem is to move the mouse pointer over the wxGLCanvas
window and click a mouse button. Sending the window a mouse event to hack a
fix does not work.
We've tracked down this problem to bad valued in the eventState class in the
eventQueue. The sequence of events are as follows:
osgViewer::View::ComputeIntersections calls
osgViewer::View::getCameraContainingPosition which calls
getEventQueue()-getCurrentEventState()
Hopefully someone has crossed this before.
The event state before the mouse click is:
-eventState0x18560430 {_handled=false _eventType=NONE _time=
0.0 ...}const osgGA::GUIEventAdapter *

Hi Tamer,
Have you tried to pass the new graphics window size to the OSG when it

Re: [osg-users] doubles in geometry?
Hi Virgina,
The OpenSceneGraph-2.3.x dev series has support for Vec3dArray etc.
Its used for loading large scale data such as whole earth shape files
where the precision is required.
There is a big but though, OpenGL hardware is designed around 32bit
floats so has to convert all 64bit floats into 32bit and this
conversion really stuffs up performance, so while Vec3dArray might be
useful for passing large scale data around its not good for rendering.
Robert.

Re: [osg-users] Texture/Shader inlined output to .osg files
Hi Mike, Should ReaderWriter should somehow preserve the representation between reading and possible future rewriting, or should it always expect an explicit option? To preserve backwards compatibility I would say that the Writer should embed the code into .osg directly. Only if user passes specified options the writer writes only the filename of the stored shader source. What filename should be stored in the written .osg file (the source filename is not preserved in the osg::Shader)? As it is done for the Images, the filename should be also stored in the osg::Shader class. This name is used then in .osg file. Should the shader source files themselves also be rewritten (perhaps the shader was modified)? I think per default not, since it is mostly unnatural to change the shader source in the program during the runtime. However if the Shader is created on the fly during the execution time, then it should be written to the file, of course. I agree it would be nice to expose the option to use a filename reference; due to all the issues, I just defaulted to the safest path. I see, but I think we should still stay by the safest path, however provide the user with the possibility to shift the shader sources to external files manually. Currently when I want a filename reference, I manually edit the .osg file; not a good answer, but it works. I know, this is the way how I also would do this ;-) Best regards, Art cheers -- mew -Original Message- From: [EMAIL PROTECTED] [mailto:osg-users- [EMAIL PROTECTED] On Behalf Of Art Tevs Sent: Wednesday, January 23, 2008 10:31 AM To: OpenSceneGraph Users Subject: [osg-users] Texture/Shader inlined output to .osg files Hello, If one writes a texture to the .osg file, then the texture is not inlined, but it's file path is written to the .osg file. I am wonder why the same doesn't happen to shader programs. The shaders are inlined into the .osg file. As from my point of view shader programs are also resources, which might be changed without changing the .osg file and hence be loaded differently on the next app start. Would it be make sense to provide a patch which do either inline the shader code or write a file path of the file from where the shader code was retrieved. This should be somehow defined through the Options object given to the reader. What do you think? Best, Art P.S.

[osg-users] How to ADD rotation to a matrix
Hello I have matrix that is placed somewhere in space. Now I want to add rotation of few degrees to the existing rotation. Therefor I create a new matrix that is placed in the origin and set the additional part of rotation. Then I move the first matrix also to origin (remove translation) and multiply it with the new matrix (m1 * m2) to get the new total rotation. After that I move the matrix back to its place. I thinks this is a correct process but in reality, the rotation and also translation aren't the expected ones. The x and z axis are interchanged for both. When I display the first or the additional matrix alone, everythin looks fine, so the problem isn't a false convertion between camera and world coordinates. Am I using a good way to add rotation of matrices or is there a general problem? How can I fix it?

Hi Edu, When I run make VERBOSE=1 on the osgviewer application I get an -lGLU entry just before the -lGL entry, while you have just the -lGL entry. So this is the cause, the question is why Cmake hasn't added in -lGLU where it should. cd into the root of OpenSceneGraph directory and then type ccmake . ie. cd OpenSceneGraph ccmake . Then press 't' to get all the advanced options, then scroll down the list to get to the OPENGL_glu_LIBRARY entry.

Did the rest of the message I sent match your situation as well? i.e. no crash as long as you don't display any text, and as soon as you press either 's' or 'h' or anything that displays text, it crashes on exit in the freetype lib?

Re: [osg-users] Win32 VS8.0 crash on exit in debugger, related to freetype
Hello Robert, Its a bit of long shot but I just had a look at the DeleteHandeler code in src/osg/Referenced.cpp and src/osg/DeleteHandler.cpp and noticed a duplicate definition of the DeleteHandlerPointer struct, one in Referenced.cpp, and one in DeleteHandler.cpp. I have removed the duplicate in DeleteHandler.cpp and checked this in. Could you do an svn update and see if this makes any difference. It was a good try, but no cigar... I still get the same symptoms. I have the impression the problem is in freetype itself, because I get some freetype functions in the stack trace. Unfortunately I can't trace into the freetype source even though I'm linking to the debug lib, which I don't understand why. I think I'll backtrack to an older version of freetype and see if that helps. But it'll have to wait till at least next Monday.

Re: [osg-users] OSG-2.3.3, Ubuntu 7.10 and GLU
Hi Edu, What probably happened is that Cmake just used the CMakeCache.txt that it built on first run of cmake in subsequent runs of cmake and didn't recreate it. Removing CMakeCache.txt forces cmake to do a full check against dependencies. FYI, use ./configure to invoke cmake as this makes sure that the Release build is enabled, the extra optimization flags make a big difference to performance.

[osg-users] XCode-Framework-osg BrainFart
After merrily going along my way using OSG on my Mac laptop for a few months, I got a new MacPro and started setting everything up fresh. No matter how I install OSG (download prebuild frameworks, or make them myself), when I add them to an XCode project I get a linking error framework not found osg. All the OSG frameworks including OpenThreads give me this error when I add them to the project. No other frameworks do this, just the OSG frameworks. I'm building on Leopard. Yes, I know something is fu-barred, I never had this problem on my MacBook Pro and I have built OSG many times. This is some sort esoteric Xcode problem and/or tangentially related to how OSG is built. OSG apps build on my MacBook Pro run fine on the MacPro, so the frameworks really are there...

[osg-users] How to override default plugins....
Hi all, I wish to supply my own plugin for the zip format, which unzips to memory. I've created my plugin derived from the existing zip plugin, overridden the readnode functions for file and stream, and at the bottom of my class I've called the RegisterReaderWriterProxy template for my class. It all appears to work, but I now have two zip file format plugins. The original, and mine. My one gets called second due to the way the RegisterReaderWriterProxy template appends to the existing list of known plugins, the plugin it is given. Ideally I would like to remove the existing plugin from the known list, thus there would only be my zip file plugin, and life is happy. However I am unclear how to do this, or even whether it is possible. Can anyone suggest what to do please ? I can see that there is a call removeReaderWriter in the registry, but can't see how I could call it with the original zip plugin reader, as this would surely have problems at shut down when the proxy class was destroyed. Please help Neil. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] XCode-Framework-osg BrainFart
Richard, Probably a stupid suggestion, but have you tried using the OSG Template, and then adding to that. You may be doing that already, but from the way you describe it it looks like you are doing it the other way around. I have not run into the problem you describe, but have found that sometimes something gets borked when you try to combine other projects with different dependencies.. When that does happen I have learned from experience (or perhaps as a function of my inexperience) that creating a fresh project, and putting it all together cleanly will solve the problem quicker than a lot of rooting around. Hope that is some help, Stephen. On Jan 24, 2008, at 10:21 PM, Richard S.

Yes, I know something is fu-barred, I never had this problem on my MacBook Pro and I have built OSG many times. This is some sort esoteric Xcode problem and/or tangentially related to how OSG is built. OSG apps build on my MacBook Pro run fine on the MacPro, so the frameworks really are there...

Re: [osg-users] How to override default plugins....
Hi Neil, The easiest way to make sure that your plugin is loaded is to pre-loaded it - just load your plugin, there are helper functions in osgDB::Registry, or just statically link your plugin into your app. The other way is to add your own alias to the Registry to map .zip to your plugin.

[osg-users] Siggraph Course
OSG users, At last night's OSG user meeting in Washington D.C., sponsored by Paul Martz and Bob Kuehne, we discussed the possibility of submitting a course again to Siggraph. We don't have much time (the deadline is January 30), but I think that we can tweak last year's submission to be ready in time. The submission process is significantly different this year, and in many ways it's more streamlined. Courses from years past are now called classes, and last either one session (quarter day) or two sessions (half day). I think we could propose two classes, one for introductory material and one for advanced topics. This would basically break up last year's submission into two pieces. Here are the required pieces for the general submission: Title of the Submission Summary Statement (50 words max) Description (150 words max) Web URL for publicity (optional) Primary submission area (choose one:) Complexity and Accessibility Future History Global Responsibility Impact on Society Professional Development and Education Siggraph Core Slow Art Computer Animation Festival Secondary submission area (optional) Primary category (choose one:) Animation and Visual Effects Best Practices, Case Studies, Tips and Tricks Creative Expression Crossing Boundaries Evolving Concepts Methods Systems Research Secondary catetory (optional) Keywords (1 required, up to 3 more optional) Details on this work appearing or submitted elsewhere If presentation at the conference is different from the materials uploaded, and details Rights information and release Abstract (pdf) Representative image (tif) Supplementary Supporting Document (optional - pdf) Supplementary videos and images (optional) For the class submission: Describe your intended audience Prerequisites Level of Difficulty Length of class Instructor Bios Example of class notes, supplementary materials Has course been taught at siggraph previously? Special presentation requirements (optional) We created most of these things last year. Who's interested in presenting? What specific topics are most interesting? -Eric ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

When osgHUD makes its way into core OSG it'll be renamed to osgWidget so if you make this change beforehand then it'll save me a job which I always appreciate ;-) Okay, it's done. :) http://osgwidget.googlecode.com I'm working on an example now using another NodeKit I created a while back (but one I haven't made a fuss about until I can pair it with osgWidget to demonstrate it's awesomeness) called osgCairo. I should have screenshots later showing osgWidget using vector graphics for buttons, scaled to whatever resolution suits your fancy with no loss in clarity. At any rate, I still hope to have this ready by April or May. Since my real life job has ZERO to do with graphics, I can only really work on it at home and at night... otherwise, it'd be ready a lot sooner. :) Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Eric, We created most of these things last year. Who's interested in presenting? What specific topics are most interesting? I would be interested in presenting the osgPPU stuff, if it is fine ;-) However unfortunately I haven't submitted any research work this year to Siggraph, hence there is no way that I get paid for the trip to Siggraph by my institute ;-) So if one of you guys is interested in presenting this, I can prepare you ;-) Best, Art -Eric ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org __ Ihr erstes Fernweh?

Re: [osg-users] Texture/Shader inlined output to .osg files
Hi Mike, I have posted a patch to the submission list which do include this changes. The patch doesn't break any current functionality of the osg but just improve it. So take a look into the description I have posted together with the patch. Or try it out. Maybe this is what also can help you. Cheers, Art --- Mike Weiblen [EMAIL PROTECTED] schrieb: Hi, Yes the .osg file Reader does support both representations of filename or embedded source text, so it does just become an issue of conveying the preference to the Writer. That raises several issues tho Should ReaderWriter should somehow preserve the representation between reading and possible future rewriting, or should it always expect an explicit option? What filename should be stored in the written .osg file (the source filename is not preserved in the osg::Shader)? Should the shader source files themselves also be rewritten (perhaps the shader was modified)? Etc etc I agree it would be nice to expose the option to use a filename reference; due to all the issues, I just defaulted to the safest path. Currently when I want a filename reference, I manually edit the .osg file; not a good answer, but it works. cheers -- mew -Original Message- From: [EMAIL PROTECTED] [mailto:osg-users- [EMAIL PROTECTED] On Behalf Of Art Tevs Sent: Wednesday, January 23, 2008 10:31 AM To: OpenSceneGraph Users Subject: [osg-users] Texture/Shader inlined output to .osg files Hello, If one writes a texture to the .osg file, then the texture is not inlined, but it's file path is written to the .osg file. I am wonder why the same doesn't happen to shader programs. The shaders are inlined into the .osg file. As from my point of view shader programs are also resources, which might be changed without changing the .osg file and hence be loaded differently on the next app start. Would it be make sense to provide a patch which do either inline the shader code or write a file path of the file from where the shader code was retrieved. This should be somehow defined through the Options object given to the reader. What do you think? Best, Art P.S. I looked into the code and encountered that reading of shaders from files is already supported but writing not. Machen Sie Yahoo! zu Ihrer Startseite.

I'd love to help test it out a bit, and perhaps apply anything I learn therein to osgWidget... I know that the IntersectVistor allows me to do certain things, but I have never really used it before. I've taken a look at the osgPick example and see that I can get the local and world coordinates of an intersection, but I am unclear as to whether there are any helper OSG classes/functions that will allow me to map that intersection point to the correct 2D coordinate to pass to the Flash player. Also, is it possible to restrict the intersection tests for my Flash drawables only?
