[osg-users] wide character in pagedlod error
Hi all, I try to combine several Chinese named .ive files to a pagedlod file, write it to disk with postfix .ive . Open it with osgviewer, it works. Then I try to do the same thing, loading .osg Chinese named files, writing to disk with postfix .osg, opening it with osgviewer, it doesn't work. I debug it, and find in memory, the Chinese named file name is not existed, only a short name which does not contain the Chinese characters. So osgviewer can't find the right .osg file to load. I also convert .ive pagedlod file to .osg pagedlod file, it not work. Why ive pagedlod can do while osg pagedlod can't. is it a bug or osg pagedlod does not support wide character? Of course I used the sentence setlocale(LC_ALL, chs); I'm using windows XP, vs2005, sp1, osg2.8 Think you, archer ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Problems with registering an osgManipulator withviewer.addEventHandler() after calling viewer.run()
Hello! Thanks for the clarification; that very likely explains what I saw when attaching a debugger. The next two question that arise are: What is the correct how and when? First, can manipulators be attached to any kind of container graph node (i. e. Group/Transform/Geode), or are there certain restrictions. Second, if I don't use viewer.run(), but a while loop that keeps calling viewer.frame(): Where is the right place to add manipulators, before or after requesting the next frame to be drawn? And, what mutexes/semaphores do I have to lock/unlock to ensure that I don't break other operations on the scene graph (though I up to now thought that the scene graph is only manipulated by update/culling etc. traversals after a call to the frame() function).

Re: [osg-users] [C++/dll] Osg export model ?
Using a Release DLL in Debug mode is a ODR violation. So the short answer is no, you can't. The fact that OSG uses the STL (e.g. std::string) in its interface, combined with MSVC debug and checked iterators, makes mixing debug and release binaries resulting in undefined behaviour. Sometimes, it may appear to work. But don't be fooled, it's often more broken than what it appears to be. In some very specific cases, it's possible to mix release and debug builds. My advice: don't.

IMHO, the redist is as much a system DLL as anything that ships with Windows, and will probably be installed on any machine that runs any programs at all, really. Lots of installers for other programs will install it automatically, so I think it's a non-issue. If you don't have it installed, just install it. You will eventually anyways, and it's quick and painless.

Re: [osg-users] problem with Windows debug binaries?
Hi Philip, I'll defer to others (Robert) for the decision, but I don't agree with your point of view. I think the redist is as close to a set of system DLLs as it can be without being on the actual Windows installation CD, so I think there's no point in putting copies of it everywhere on your system. Personally I would trade the whopping 1.6 MB this would take up for the assurance that the binaries will work on all machines. 1.6MB per project, per instance of the binaries, per... That's the point, they're meant to be system-wide, not all over the system. Of course if you want an end-user's first experience running osgviewer to view some model they found online to be a cryptic error message, then by all means leave things the way they are. OSG is not an end-user app. It's a library which you'll use to develop other apps. If you downloaded the binary packages, it's either because you wanted to evaluate it for possible use in your project, or you want to use it in an existing project (perhaps in place of a previous version). Unfortunately, not every first time user of OSG is going to have MSVC installed or the runtime libraries installed. A note in the readme should suffice. We can even have a special readme that we only include in the Windows binary packages. As I said, if they want to do almost anything else on the machine they'll need the redist, so whether OSG is the reason they install it or anything else makes little difference. In all likelyhood they'll have Visual Studio installed anyways... So I think we're arguing about a minority of users. What we might consider doing would be, instead of generating tarballs, for Windows we could generate an .msi installer that would install the runtime correctly if needed (like most apps do). We could even generate both, and make it clear that if you download the tarball you need the runtime installed already. There is no disadvantage to including the runtime DLLs aside from an extra 4 files and 1.6MB of space used. I think this is really a no brainer. There is no disadvantage to not including the runtime DLLs. Period. And we don't pollute the system with copies of DLLs that will be installed to the system directories by some other app sooner or later. Honestly, if there was a way for me to have one version of libpng, libjpeg, etc. like on a Linux box, installed system-wide, I'd do that. Unfortunately, it doesn't work like that on Windows. But at least we can keep the dependencies we need to ship to a minimum.

I believe the intent of the binary packages is to provide a shortcut for developers on Windows to get OSG and the dependencies. If that's the case, then it wouldn't make any sense to include the MSVC. The official distribution is the source tarball, no? If you are a developer and want to test OSG on different hardware platforms, then you need something that run with minimum hassle: Think of build an usb pen and ask some colleague of yours to run that specific OSG example and see if it works ok on his (possibly old) pc I have been in this situation quite often. I came up with a folder that include the OSG install + osg data + a run.bat that set up OSG_FILE_PATH (it woul really be nice if there was a way to define a default path) It seems to me that, for testing purposes, the inclusion of system dll would be good, at least as a default off option. I silently had to patch osg CMakeFile to do exactly what Philip suggested but did not dare to ask for inclusion ...I know windows only hack are not exactly welcome. If you have to build apps that deploy as binaries in platform that you do not control (as it happen to me), it could be handy to have a reference osg installation to test the deployed platform against, as it happens that there are bugs related to bad OpenGL drivers. So the need to test with official OSG examples (test) I also think that OSG could benefit from extensive run time testing, on different HW platform and drivers, possibly published as a dashboard, as CDash already support an other sw like VTK do. In that usage pattern, asking for a runtime installation that requires Admin privilege to just save some bytes seems incorrect. Just my 0.2 Euros Luigi cory Philip Lowman wrote: .

Re: [osg-users] problem with Windows debug binaries?
Hi all, I think I'll bow out of this discussion, we're not going forward at all and instead concentrating on relatively uncommon use cases. I think the big picture is the case where the binaries are used either to evaluate OSG for an upcoming project or to use in an existing project. In those cases, the machine will have the runtime already. OSG is not an end-user app, so the task of making installation and running easy on a bare machine is up to the app developer / packager, not to OSG itself. If one of you disagrees with this, you can submit a change to do it some other way, and see what Robert thinks. I think all possible opinions have been voiced so if someone actually wants to change things, be my guest, but let's stop just talking about it and running in circles...

Re: [osg-users] problem with Windows debug binaries?
Hi all, hi Robert, for Windows we could generate an .msi installer If CMake can do that, I'll open a bottle of Champagne! :) That would be great to directly generate an installer for each platform... But to end up the discussion, I'll say, until we got a real installer (which is the best solution), that: - Tweaking the CMake script to add special DLLs in the tar.gz is a bad idea. DLLs should thus not be added in the archive. - There should be a note and a link on the dowload page (and maybe in a README as J-S suggested). I suggest Robert (or anyone having write access to this page) to add, after the Windows Visual Studio 8 packages the following wiki text: - Requires the MSVC 2005 SP1 redistributables for your platform ([http://www.microsoft.com/downloads/details.aspx?FamilyID=200b2fd9-ae1a-4a14-984d-389c36f85647 x86], [http://www.microsoft.com/downloads/details.aspx?FamilyID=eb4ebe2d-33c0-4a47-9dd4-b9a6d7bd44da x64] or [http://www.microsoft.com/downloads/details.aspx?FamilyID=747aad7c-5d6b-4432-8186-85df93dd51a9 IA64] And the same for 2008 packages (http://www.microsoft.com/downloads/details.aspx?FamilyID=a5c84275-3b97-4ab7-a40d-3802b2af5fc2 (x86), http://www.microsoft.com/downloads/details.aspx?FamilyID=ba9257ca-337f-4b40-8c14-157cfdffee4e (x64), http://www.microsoft.com/downloads/details.aspx?FamilyID=dcc211e6-ab82-41d6-8dec-c79937393fe8 (IA64)).

I think the redist is as close to a set of system DLLs as it can be without being on the actual Windows installation CD, so I think there's no point in putting copies of it everywhere on your system. Personally I would trade the whopping 1.6 MB this would take up for the assurance that the binaries will work on all machines. 1.6MB per project, per instance of the binaries, per... That's the point, they're meant to be system-wide, not all over the system. Of course if you want an end-user's first experience running osgviewer to view some model they found online to be a cryptic error message, then by all means leave things the way they are. OSG is not an end-user app. It's a library which you'll use to develop other apps. If you downloaded the binary packages, it's either because you wanted to evaluate it for possible use in your project, or you want to use it in an existing project (perhaps in place of a previous version). Unfortunately, not every first time user of OSG is going to have MSVC installed or the runtime libraries installed. A note in the readme should suffice. We can even have a special readme that we only include in the Windows binary packages. As I said, if they want to do almost anything else on the machine they'll need the redist, so whether OSG is the reason they install it or anything else makes little difference. In all likelyhood they'll have Visual Studio installed anyways... So I think we're arguing about a minority of users. What we might consider doing would be, instead of generating tarballs, for Windows we could generate an .msi installer that would install the runtime correctly if needed (like most apps do). We could even generate both, and make it clear that if you download the tarball you need the runtime installed already. There is no disadvantage to including the runtime DLLs aside from an extra 4 files and 1.6MB of space used. I think this is really a no brainer. There is no disadvantage to not including the runtime DLLs. Period. And we don't pollute the system with copies of DLLs that will be installed to the system directories by some other app sooner or later. Honestly, if there was a way for me to have one version of libpng, libjpeg, etc. like on a Linux box, installed system-wide, I'd do that. Unfortunately, it doesn't work like that on Windows. But at least we can keep the dependencies we need to ship to a minimum.

Re: [osg-users] Converting from Partiview - suggestions?
Hi Jeff and J-S, There's this page (http://www.openscenegraph.org/projects/osg/wiki/Community/LanguageWrappers) which lists available wrappers. As far as I can tell, both the original PyOSG and osgPython by Miguel Escriva et al. haven't been updated since early 2007. I'm still actively using (and maintaining) osgSWIG, with Python being the main target (see http://code.google.com/p/osgswig/). From reading your problem, I'm sure you can use a small Python scripts to get results fast without too much effort. For example, in your script you would import osg modules, use some DB/file reading loop to read values, generate objects in a scene graph tree, and write results away in an OpenSceneGraph format using a osgDB.writeNodeFile(mynode, myfile.osg). You can directly view results from within a python-based viewer, or use osg's osgviewer application to see the saved files. I advise you to take a look at the examples to get an idea of osgswig's use, and learn a bit of osg at the same time. Get back to us if you get stuck... Gerwin ps. if you want to have per-vertex control of shapes through osgSWIG I advise you to stick to OpenSceneGraph 2.4. (we have serious wrapping problems with some osg 2.6+ structures).

Re: [osg-users] osg::View NO_LIGHT bug?
Ben,
osg::View's setLightingMode with NO_LIGHT as a parameter doesn't actually
turn any lights off (just look at the source in osg/View.cpp). If the
lightingMode is *not* NO_LIGHT, then it sets light 0 with the default 0.8
diffuse value etc. I presume this is by design, although I'm not sure why!
Actually, this is all a bit confusing. For example, SceneView sets a global
ambient light model that you have to suppress after the fact.
Similarly, I notice that osg/View has LightingMode as enum {NO_LIGHT,
HEADLIGHT, SKY_LIGHT}, whereas SceneView has enum Options {
NO_SCENEVIEW_LIGHT = 0x0, HEADLIGHT = 0x1, SKY_LIGHT = 0x2}, which looks a
little bit... random... to me if any default conversion between the enums is
done. However a quick trawl through SceneView looks okay (LightingMode in
SceneView is typedef'd to Options).

Re: [osg-users] osg::View NO_LIGHT bug?
- From: Ben Axelrod at 2009-02-18 07:09-
I
still dont know why osg::View::NO_LIGHT doesnt work, but to answer my own
questions, to turn off the default light completely:
{
light-setAmbient(osg::Vec4(0,0,0,1));
light-setDiffuse(osg::Vec4(0,0,0,1));
light-setSpecular(osg::Vec4(0,0,0,1));
}
Hi Ben,
This is the best solution that I found. I tried the example code
from OSGQSG but it didn't work properly. I appreciate comments here
that it's not ideal because light#0 is wasted but it seems safer than
trying to hijack this light which viewer expects to use.
Any suggestions or clues about taking control of light#0 will be greatly
appreciated.

Re: [osg-users] problem with Windows debug binaries?

CMake supports integration with NSIS. Not sure if there is support for MSI yet. Wix looks like a promising candidate. But to end up the discussion, I'll say, until we got a real installer (which is the best solution), that: - Tweaking the CMake script to add special DLLs in the tar.gz is a bad idea. DLLs should thus not be added in the archive. - There should be a note and a link on the dowload page (and maybe in a README as J-S suggested). I suggest Robert (or anyone having write access to this page) to add, after the Windows Visual Studio 8 packages the following wiki text: - Requires the MSVC 2005 SP1 redistributables for your platform ([ http://www.microsoft.com/downloads/details.aspx?FamilyID=200b2fd9-ae1a-4a14-984d-389c36f85647x86], [ http://www.microsoft.com/downloads/details.aspx?FamilyID=eb4ebe2d-33c0-4a47-9dd4-b9a6d7bd44dax64] or [ http://www.microsoft.com/downloads/details.aspx?FamilyID=747aad7c-5d6b-4432-8186-85df93dd51a9IA64]; And the same for 2008 packages ( http://www.microsoft.com/downloads/details.aspx?FamilyID=a5c84275-3b97-4ab7-a40d-3802b2af5fc2(x86), http://www.microsoft.com/downloads/details.aspx?FamilyID=ba9257ca-337f-4b40-8c14-157cfdffee4e(x64), http://www.microsoft.com/downloads/details.aspx?FamilyID=dcc211e6-ab82-41d6-8dec-c79937393fe8(IA64)). Is that okay for everyone? No arguments here. Until an installer is once again available for casual end-users just linking the URLs you provided seems reasonable to me. -- Philip Lowman ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
