Re: [osg-users] Very simple Firefox-Plugin to display osg-files
Forgot to mention: - Check if the cURL plugin use some other side-by-side assemblies (such as VC8 non-SP1 for instance). Maybe you'll need to recompile it? - Also check on Vista if you can, because Vista simply pops-up an error (cannot load the executable) when correct side-by-side assemblies are not found (but I guess not for delay-loaded DLLs...?). - And finaly, try your plugin on a clean machine with no MSVC installed, and no redistribuables installed, if possible. And to be more precise: private side-by-side assemblies can sometimes NOT coexist (VC8 non-SP1 / VC8 SP1 for instance) since they would be in the same dir with the same name. However, they ensure your plugin will work even with no redistribuables installed, at the cost of some kB in the plugin installer. Hope you'll find how to make it work.

Hi Andreas, I strongly suggest you to use (well, keep) SP1 since dependencies use it, and as it seems to be no reason keeping non-SP1. Your problem is maybe about how side-by-side assemblies are used under Windows (XP, Vista...). You may document yourself on that subject. You roughly have to know that before Win2000, Windows tries to load DLLs looking in the PATH. But after 2000, DLLs can also be located in special directories, so that different versions of the same DLL can coexist (See my project doc below).

Re: [osg-users] Very simple Firefox-Plugin to display osg-files
HI Andreas, Nice to see the plugin work coming along. The setUpViewerAsEmbeddedInWindow calls tricks the viewer into thinking that it has a valid graphics context, but in reality the GraphicsWindowEmbedded that this call creates is just a non op for all makeCurrent/swapBuffer calls, which means the viewer itself can't do these operations. This scheme only works when you have one context per viewer and run the viewer single threaded, and the app that calls viewer.frame() creates it's own graphics context and makes it current, and does the swap buffers call itself. The Embedded functionality of osgViewer does make it extremely easy to graft an viewer into an code that provides the graphics context, but it is limiting - you won't be pbuffer support, or any multi-window/context support, nor threading support, but for a browser this possible isn't to much of an issue as you aren't likely to be drive a full blow simulation from a browser. To get get the full capabilities of osgViewer then using the window inheritance features of osgViewer would be the way forward - here you'd like the browser provide the parent widget that osgViewer will create it's own OpenGL GraphicsContext within. This is typically more awkward to code as you have to go get the native window handle, but if this is possible then you should be able to code up a solution similar to the osgviewerMFC example.

If someone would like to try it: - it´s windows only, firefox 3.04 only (newer versions should work) - you must have osg2.7.6 installed, bin-dir in your path. The plugin is compiled with VC 2005, so maybe only this will work - download the plugin here: http://raumgeometrie.de/testplugin/npbasic.dll (it´s so small, not even worth zipping) - testpages here: http://www.raumgeometrie.de/testplugin/gallery.html I attach the source to the plugin. But be aware of the fact, that the most time-consuming step of building this plugin was to get the basic-example I started with to compile. I will send a zip with project-file later on. Note that the sample-plugins shipped with the firefox-source do use completely different function-names than those described in the plugin-api that can be read on the firefox-dev site. I sticked to the functions named in the sample (and had to research with google for some things). I don´t know if their own samples are outdated, or if the api-documentation is outdated or whatever. The thing that does not (!) work is to put several instances of the plugin on one page. Maybe robert can jump in and explain how the window = viewer-setUpViewerAsEmbeddedInWindow(100,100,800,600); viewer-setSceneData(loadedModel.get()); (which works like next to magic for me) does find it´s OpenGL-context. Probably this is not so easy when there is more than one context. But even if this won´t work, it´s quite a nice plugin so far.

Re: [osg-users] Very simple Firefox-Plugin to display osg-files
Hi Andreas, I had a quick review of the plugin.cpp you posted and it's tiny, which is definitely a good thing ;-) I see that code you are using is being passed in a native window handle so there is probably a reasonable chance that we could just use this with and have the osgViewer create the graphics context using the window inheritance feature. This might be a way of make the code more portable across platforms as well as it would reduce the amount of platform specific code. This is a bridge that could be crossed later though. In the review of the code I spotted that the plugin.h was referenced, but you didn't include the plugin.h. Could you post this. Without the header I can't say for sure, but my guess is that the OSG related global variables could be moved into the nsPluginInstance class that you've created. Do you have particular web documentation you've been using for inspiration?

I am now packaging the plugin and encounter a problem: The plugin starts (meaning that the core osg-dlls are found), but it does not find the osg-plugins (I have removed osg from my path for testing reasons). Usually when you start an osg-application and put the plugins into the applicaiton-folder (or below into the correct plugin-folder) they are found. Maybe this is different here, as the plugin itself is not an application but a dll. Any idea how I could trick the osg to make it find the plugins?

It is not yet packed, I will have to carefully read the documentation on how to do this (I would like the plugin to be downloaded automatically when a user does not have it). If someone would like to try it: - it´s windows only, firefox 3.04 only (newer versions should work) - you must have osg2.7.6 installed, bin-dir in your path. The plugin is compiled with VC 2005, so maybe only this will work - download the plugin here: http://raumgeometrie.de/testplugin/npbasic.dll (it´s so small, not even worth zipping) - testpages here: http://www.raumgeometrie.de/testplugin/gallery.html I attach the source to the plugin. But be aware of the fact, that the most time-consuming step of building this plugin was to get the basic-example I started with to compile. I will send a zip with project-file later on. Note that the sample-plugins shipped with the firefox-source do use completely different function-names than those described in the plugin-api that can be read on the firefox-dev site. I sticked to the functions named in the sample (and had to research with google for some things). I don´t know if their own samples are outdated, or if the api-documentation is outdated or whatever. The thing that does not (!) work is to put several instances of the plugin on one page. Maybe robert can jump in and explain how the window = viewer-setUpViewerAsEmbeddedInWindow(100,100,800,600); viewer-setSceneData(loadedModel.get()); (which works like next to magic for me) does find it´s OpenGL-context. Probably this is not so easy when there is more than one context. But even if this won´t work, it´s quite a nice plugin so far. Read the source as an inspiration on how very easy this was - hopefully someone can jump in and do this for linux and mac.

Hi Andreas,
I had a quick review of the plugin.cpp you posted and it's tiny, which
is definitely a good thing ;-)
I see that code you are using is being passed in a native window
handle so there is probably a reasonable chance that we could just use
this with and have the osgViewer create the graphics context using the
window inheritance feature. This might be a way of make the code more
portable across platforms as well as it would reduce the amount of
platform specific code. This is a bridge that could be crossed later
though.
In the review of the code I spotted that the plugin.h was referenced,
but you didn't include the plugin.h. Could you post this. Without
the header I can't say for sure, but my guess is that the OSG related
global variables could be moved into the nsPluginInstance class that
you've created.
Do you have particular web documentation you've been using for inspiration?
Robert.

No.

GetModuleFileName(handle, filename, sizeof(filename));

}
This should work because the list of loaded DLLs is searched first by
LoadLibrary().
This works! Only one should not free the handle, as the lib is
(probably) not loaded again, this gives a crash.
I have then used Luigis way of extracting the path, as I do not have the
header to PathRemoveFileSpec.
I´ll pack this in the late evening, seems to be working now.

You should do FreeLibrary() because it's reference counted internally.
see http://msdn.microsoft.com/en-us/library/ms683152(VS.85).aspx:
The system maintains a per-process reference count for each loaded module. A
module that was loaded at process initialization due to load-time dynamic
linking has a reference count of one. The reference count for a module is
incremented each time the module is loaded by a call to LoadLibrary. The
reference count is also incremented by a call to LoadLibraryEx unless the
module is being loaded for the first time and is being loaded as a data or
image file.

Re: [osg-users] Very simple Firefox-Plugin to display osg-files
Hi all, I have now packed the plugin and the necessary osg-libs into an xpi-file. You can use http://raumgeometrie.de/testplugin/test.html to download the plugin and test it. Use the source-view of the html-page to see how it is embedded. Note the following problem: Even though I have provided the plugin-url in the embed-tag, the plugin does not download when clicking on the icon. The link below (Hier Plugin, means plugin here) does work though. In the mozilla-docs it says that I have to register the mime-type with .htaccess, but either this doesn´t work or I made another mistake. Maybe someone can give insight on this. The plugin-package is lean and mean, meaning that it only works for osg and ive-files with no effects and jpg, gif or png-textures. For it to work with more filetypes I would have to pack all osg-plugins into the package. Please test it and report if it works. It would be great if someone could test on a machine that has no developer-tools installed, as dll-problems will occur here more likely than on a dev-machine that has all kinds o packages installed.

The link below (Hier Plugin, means plugin here) does work though. Yes, that's confusing, but with the link it works.

I get just the blue background. Again, good work, and I look forward to lots of cool browser apps in the future using this!

I am seeing the same behavior as well. Just an empty osgviewer embedded in my browser.

Hi Andreas, That´s a mistake. Look at the page source, it should load a model. If it does not, it means that something is missing. Probably, as I fear, a dll that my system has and yours don´t. I´ll have to look into that. Well, all I get are a few message boxes (I guess those are debugging messages :-) ) and then an empty osgviewer. Do the OSG error messages go to your webserver logs? Perhaps you could redirect osg::notify's streams to print them into the browser? Or a console in the OSG viewer...

Re: [osg-users] Very simple Firefox-Plugin to display osg-files
Hi all, I have now repackaged the xpi. I have turned my old laptop, that does not have dev-libraries, and tried it, and it didn´t work. On my dev-machine it works, even if I remove osg from my path. But: I have lots of libs in my path and in my windows-system. Please download the xpi from raumgeometrie.de/testplugin/test.html (link on bottom) and tell me if it works. If it doesn´t, please give hints what might be wrong.

Re: [osg-users] Very simple Firefox-Plugin to display osg-files
That works completely. I installed it without any other installed and it works without error.

Re: [osg-users] Very simple Firefox-Plugin to display osg-files
Hi, I have reviewed my own code and realized that, of course, the global variables were no good idea. I was not aware of the fact, that a plugin (the dll) is loaded only once, and each time the plugin is embedded, a new instance of the plugin-class is created. The global variables that live in the dll exist only once, thus it was not possible to display more than one model on a page. I have refactored this, now one can display several models on one page. There are some more issues, but I will work on that tomorrow.

Re: [osg-users] Very simple Firefox-Plugin to display osg-files
Thanks for your contributions! I'm really eager to see what projects will use this plugin of yours. It would be a great way of attracting new developers to OSG if they could check out demos online :) On Thu, Dec 4, 2008 at 4:08 PM, Andreas Goebel [EMAIL PROTECTED] wrote: Hi, I have reviewed my own code and realized that, of course, the global variables were no good idea.
