Re: [osg-users] Appeal for use of human names
I have read all the posts on this interesting topic. Both sides has valid reasons for using actual names and for nicknames. I believe a simple compromise can exist that should make everyone happy, even for Robert. If a person wishes for his/her identity to be unknown on the mailing list or forums, then that right should be honoured. Yet to be respectful of other users, visitors, contributors, etc, the person should choose a simple suitable false name. It may be another real name or completely fictional, as long as it is not leetspeek (stupid nicknames with digits and punctuation amongst the letters), or combination of everyday words, example Night Hawk that me have here. Though personally I have no problems with Night Hawk, for I am one of those people that honours a person's request to be referred by the person's nickname (their own choice or given by another) rather than their actual name. Rizzen is far from my real name. It is a random generated fictional name. From past replies to my posts on this mailing list, Robert has had no problems referring to me as Rizzen, showing that even fictional names do work. :) Rizzen ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Simple request: country codes
Seeing that we all live all over the globe and communicate with each other no matter where we live. It would be very polite to state your country of origin in your supplied contact details and if you supply telephone numbers to also include your country dialling code. No everyone knows every country's states/provinces and their abbreviations. Even if you recognize a name to be English, there is a handful of countries that would have citizens with that particular name. For English names the countries could be Ireland, UK, India, Sir Lanka, Australia, New Zealand, USA, Canada, South Africa, Zimbabwe, Zambia, the West Indies, and the list goes on.

[osg-users] Terrain Texturing
Hi everyone, I've implemented Terrain Rendering Using GPU-Based GeometryClipmaps algorithm with frustum culling, instancing, normal maps, procedural texturing etc... And now I want to implement texturing of terrain other than procedural texturing. Because I want to cover terrain area with unlimited texture data. A lot of texture data means a lot of alpha map. (Texture Splatting) and GLSL doesn't allow more 16 sampler2D. Can I cover terrain area with unlimited texture? Thank you very much for your help. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] building osg statically linked on Win32
First thanks for the answer! I can't belief that I'm the first one asking for static libs, because some win-apps based on OSG imho are built static. So someone already has gone this way... In cmake I found the options to switch from /MDd and /MD to /MTd and /MT but I can't still find the option to switch from Dynamic Library to Static Library. In the vcproj-File it seems to be the option RuntimeLibrary, that has to set from 0 to 1, but I can't find an equivalent in the cmake options (and I'm afraid of modifying everything by hand). And finally I'm not sure, if the preprocessor flags like OSG_LIBRARY in osg.vcporj have to extended to OSG_LIBRARY_STATIC like in the OSG 1.2 solution.

Re: [osg-users] Warning on Add shader to the scene
Hi Gordon, here change the line 99 in Program.cpp into this: _geometryVerticesOut(1), _geometryInputType(GL_TRIANGLES), or with other words just set the _geometryVerticesOut to 1 instead of 0. It should be 0 per definition, however this does produce warnings. Changing to 1 doesn't break any functionality and also works fine. If one would like to use the geometry shaders she/he had to change this value in any case. Hence 0, my opinion is, that 0 shouldn't and wouldn't be used at all.

Re: [osg-users] build errors when integrating vterrain into existing app
Hi Bryan,
I think there the best place to ask support questions about compiling
VTP examples is VTP lists. There are people who staddle the OSG and
VPB communities, so you may be lucky in catching the attention of one
of these that just so happens to also know about VTP + MFC
integration, but your chances of a useful reply and much higher on VTP

The mfcSimple app builds fine, but when I import vtlib, vtdata, and vtosg

I reckon there is some #include not put somewhere, but haven't seemed to be

When limitations are hit up against bits of the OSG that are limiting things are often refactored - and often by those hitting up against the limit. You can use 8 bit encoding with standard strings, osgText::String supports this, but my guess is that you won't be able to use this route through given the text will just be set the usual default methods. Refactoring ScalarBar to use osgText::String is a possibility. I'm afraid I'm rushed off my feet as usual so if you would like this change you'll need to chase it up yourself. If you do find a sensible fix then just send the changes into a osg-submissions and I can then review to see if they are in keeping with the basic design/implementation of ScalarBar and the wider OSG.

From past replies to my posts on this mailing list, Robert has had no problems referring to me as Rizzen, showing that even fictional names do work. :) Yes, the key is *use* you psuedo name in place of true name, rather than just not using a name at all. The real problem is posts that address no one, and have no signature, where there is absolutely no indication how one is addressed. Its rude communitcation that all too easily can stem from hiding behind anonymity. Polite discussions go like this: Hi X, Some text Post from X: Some other points Regards, Z Drop the address and your have: Some text: Some other point Now which of these is likely to be taken the wrong way, and to lead to deterioration in communications? This is basics of human communication. Personally I find anonymity a slippery slow, its communication that from the outset is based on one party being deceitful. As Nicolas pointed out, anonymity can be used to avoid accountability, which in turn can all too easily lead to peoples conduct dropping. As someone who's working life is very entwined with the osg-users community I am very exposed this conduct dropping. Sadly poor conduct in one poster can then rub off on to others, and all too soon its a rabble and thoroughly unpleasant place for everybody to hang out. As project lead and mailing list administrator its my role to try and sheppard things in a better direction.

I can say that fixes would be welcome. There was a submission posted to osg-submissions about half a year ago that made changes for a Windows static build, but in review it looked to be it might fix the static build but break other things so I made a brief call for feedback from other windows dev's but didn't get a response. Rather than risk breaking the build for 99% of people I didn't merge. You could possible go back into the archives to have a look at this.

[osg-users] AP203 and OSG
Hi all I am newbie to Openscenegraph. I am developing a simulation application, which involves the simulation of mechanical parts. I have to import the CAD models from a STEP (AP203) file and render the models using OSG. One solution what I have in mind is, 1) Using OpenCascade for reading the STEP files and tries to render using the OSG. 2) But how to transfer the SOLID model data from OCC to OSG? 3) What are the different methods/approaches, I should try to display the SOLID models in OSG. 4) Can anybody give some hints or directions which will help me to finally reach the goal?

Re: [osg-users] Warning on Add shader to the scene
Hi Robert, yes, I saw the specifications and in deed 0 is the default value. I also think that this is a driver bug. However I have the same warning with different driver versions (older and newer one). Maybe the nVidia guys just overseen it. One solution would be just to set this value to 1. I haven't encountered any issues using it like this. Other (maybe more elegant) solution would be not to set this value at all if no geometry shaders are used. However this is not so easy with the current structure of the osg's shader implementation code, I think. It would be cool if somebody could post some comments on this: i.e. if one have this warning and what happens if one change the default value to non zero one ;-) Best regards, Art --- Robert Osfield [EMAIL PROTECTED] schrieb: HI Art, Thanks for the explanation. Looking at the specs at: http://www.opengl.org/registry/specs/EXT/geometry_shader4.txt It say the default value of GL_GEOMETRY_VERTICES_OUT_EXT is 0, which by convention the OSG normally tried to honour in its own defaults. From the above text: GEOMETRY_VERTICES_OUT_EXT Z+GetProgramiv 0 max # of output vertices 2.16.4- If this setting is producing a warning then its a bit surprising, might it be a driver bug? If changing to default of 1 fixes the warning then it'd be worth introducing, but... its not the OpenGL default value so we'd need to make a comment why the value is non default. Robert.

Re: [osg-users] OpenFlt file causing crash in optimizer
Hi All,
I'm just reviewing Jason Daly's submission of Kamil Krupa's fix to
Optimizer.cpp as a workaround to the problem handling some OpenFlight
files. Jason kindly stepped in making as alas Kamil didn't get around
to sending it to osg-submission.
I have now reviewed the fix and am not entirely comfortable with the
changes. I'm not 100% sure of the failure mechanism as I don't have a
model that reproduces the problem first hand. Reading the posts it
seems the LessGeode functor was buggy, and reviewing it I can see that
it could fail in certain circumstances. The culprit is:
struct LessGeode
{
bool operator() (const osg::Geode* lhs,const osg::Geode* rhs) const
{
if (lhs-getStateSet()rhs-getStateSet()) return true;
if (lhs-getNodeMask()rhs-getNodeMask()) return true;
return false;
}
};
I think the a better implementation would be:
struct LessGeode
{
bool operator() (const osg::Geode* lhs,const osg::Geode* rhs) const
{
if (lhs-getNodeMask()rhs-getNodeMask()) return true;
if (lhs-getNodeMask()rhs-getNodeMask()) return false;
return (lhs-getStateSet()rhs-getStateSet());
}
};
I don't a model to test. I have just tested the OpenFlight models I
have here and all run OK, but then they did before...
Soo... I've just checked in my change to Optimizer.cpp into SVN, you
can also grab it only via:
http://www.openscenegraph.org/svn/osg/OpenSceneGraph/trunk/src/osgUtil/Optimizer.cpp
Could OpenFlight users try out this change and let me know if things
are fixed, or hooorribbly borken...
Thanks,
Robert.

Re: [osg-users] osgViewer::View::getCameraContainingPosition() returns weird results when using slave cameras
Yes, I think you are right, it's something in that vein. I can trick it into returning the correct result by scaling the input (normalized) coordinates to compensate for the change in the viewport aspect ratio. So that implies that somewhere, old values are still lurking around.

If I resize the viewport after creation, computeIntersections() no longer returns correct results -- the Y value is incorrectly scaled. It only works correctly if I resize the window back to its original aspect ratio. Yes, that sounds like a different problem. In my case, I was not getting correct results from computeIntersections() whenever CompositeViewer was using a single view with slave cameras - no resizing at all involved, just using setUpViewAcrossAllScreens(). You'll have to dig further.

[osg-users] [VPB] Multiple textures
Hi Robert, In osgdem, are multiple textures combined into a single temporary texture and then written to the output file or each texture is generated as a temporary texture and all these temporary textures are written, as separate textures, in the geode definition? I have tried using multiple textures for the same position or geometry and it works. The reason I ask this is because I want to have various layers of textures generated using osgdem and I would like to turn some layer on and off based on, say a key input.

DYNAMIC_OPENSCENEGRAPH is the one you're looking for I think. And I believe most users use dynamic libraries for OSG because frankly, it would give a huge executable. I personally prefer to have OSG installed in a general place on my system and refer to it with environment variables in my own projects. That way I have only one copy of it, and also I can update OSG from SVN and then the updated version is available to all my projects at once. At work we have OSG in CVS alongside our projects, so we refer to it with relative paths (..\..\OSG\lib.rel\win32-vc8\osg.lib) in our projects. That also works well. There's also the issue of plugins: in the past linking OSG statically would not pick up plugins and then you'd have problems loading files from your program. I think that was fixed, but I can't remember the specifics. The archives will know more, my memory is not what it once was.

Hi Andreas, Please reply directly to the thread you are engaged in instead of a digest mail, as this makes threads hard to follow. Run into the same(?) problem: Got a lot unresolved external symbols... I modified all CMakeLists.txt-Files like above and recompiled the osg-Projects but still get the same linker errors. I doubt that my problem is connected to the CMakeLists-Modification, isn't it? You might have to delete your CMakeCache.txt and regenerate the project files with CMake if you make this kind of change. CMake caches old values and sometimes, it does not regenerate the projects correctly and reuses the cached values even if it shouldn't. Note that I haven't tried linking OSG statically myself, so others might have more guidance and troubleshooting help to offer on your specific problem. By the way: Is this right, that CMake attaches to all libraries the prefix osg25-? Only to DLLs. Libs should not have the prefix. If they do when building a static OSG, that's a bug that should be fixed. BTW the prefix depends on the version of OSG you have, but is not directly the version itself - the SVN version is now at 32.

Perhaps I can add a bit more qualification to this. The OpenSceneGraph is a collaboration on hundreds of developers (we hit 300 contributors earlier today), only a handful of which have ever been anything need full-time developers on OpenSceneGraph itself. The majority of contributors work for companies, universities and other institutions that use the OpenSceneGraph and contribute their additions/fixes/amendments that help make their application development easier by virtue of sharing their contributions. From a personal level, over the years I have averaged around 30-50% of my time being paid open source or closed source work, the rest in work supporting and developing the OpenSceneGraph is done without payment.

Re: [osg-users] osg-conv collada
I've tried running the prebuilt binary for osgconv on Linux, but they don't come with osgdb_dae.dll - could someone please send me a copy, as I don't have visual studio? or could someone send me their osgconv_dae.so on linux to try on my system? i'll try recompiling everything again... thanks ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
