[osg-users] Compass/Navigator Widget
Hi, I'm new to OSG and would like to know if there's a standard method/class to create an alpha-blended compass/navigator widget like the one in Google Earth. I'm an experienced OpenGL user and normally, I would simply map a few overlapping quads with alpha-blended textures and draw them last before SwapBuffer(). I assume that this is a common task in OSG and that there's a more stramlined way to do this.

[osg-users] osgDem & VirtualPlanetBuilder
Robert, So, should I follow the procedure outlined in osgDem's User guide or use VirtualPlanetBuilder instead? osgDem did not built as part of my OSG v2 project, so I assume it's only available in VirtualPlanetBuilder now? I'm sure this is all chrystall-clear to you guys, but for a newbie, it's quite a mind bender ;) Thanks. You wrote: - Hi Nick, The paged database support in 2.x has been refactored so that is now sits outside of the OpenSceneGraph in an new project called VirtualPlanetBuilder: http://virtualplanetbuilder.osgforge.org/ This a tool for generating paged databases from geospatial imagery and DEMs, within this project you'll find the osgdem application that you can run as command line tool to generate your databases. Do a search for osgdem on the openscenegraph.org wiki to get docs on how to use osgdem. I'll move this docs to the VPB website soon. The database that VPB generates don't require osgTerrain to work, rather are built from core osg library nodes, geometry and textures. The osgViewer library has inbuilt support for database paging so all you need to do is load the topmost node of paged database and it'll do the rest. osgTerrain is now focused on runtime rendering of terrain data, and is still very much in its infancy. The intention is that will be a framework for things like CLOD terrain and shader based terrain techniques. VPB may also utilise osgTerrain in future rev's of both.

[osg-users] osgDEM and PugetSound Demo
OK, I'm almost there...
I'm trying to generate the PugetSound sample database as outlined in the

Unfortunately, it seem that the system uses extentions that my graphic card
cannot support. I have a 2002 nVidia Quadro2 MXR/EX/Go with 32MB ram.

It looks like everything is going fine until it tries to create a pixel
buffer. Is there a way around this or do I have to buy a new graphic card?

Robert, Thank you for the clarification. The text is still on the Wiki however. Check this link: http://www.openscenegraph.org/osgwiki/pmwiki.php/UserGuides/Osgdem It's been one week with OSG and so far, here are my observations: Pros: * Great code quality. A good balance between creativity and the use of STL. * Interesting architecture - specially for the plug-ins. * The most responsive mailing list I have ever seen for an OSS project. Great attitude, focused on helping. No flame war... Keep it up guys ;) * Extensive set of examples. I'm currently going through those, and It's probably the best way of learning OSG. Cons: * The documentation blows. Thankfully, this is being adressed by the guys at Skew Matrix. As a newbie, my biggest problem was figuring out the recent history: change of server, the relation between OSG and VirtualPlanetBuilder. Basically, it's not possible to know the current state of OSG without some major head scratching ;) I'm OK at writing manuals (I actually enjoy this), so I'll take a shot at it and document the directory structure for Windows. Jean-Sebastien sent me a detailed email about this (thanks J-S!) and I hope to be able to translate this into one or two illustrations. Many times, just having screenshots & diagrams of the process would save a lot of time. This is a *visual* project after all ;) Thanks everybody.

Re: [osg-users] osgDem Windows Front-End
Antoine, Thanks for the advice. Actually, I have already started saving osgDem parameters as XML to allow users to save their sessions. My clients have "Command-Line-O-Phobia", so they asked me to add a simple UI for executing osgDem. It's not difficult, but I was wondering if anyone had done this in the past. I'm specially interested in how to provide feedback while the data is being generated. osgDem works like a 3rd party renderer like Mental Ray and RenderMan. Some people cannot use these products unless they have a graphical UI to interact with.

Re: [osg-users] osgDem Windows Front-End
Robert,
Thanks for the update. No matter how it's implemented internally, there is
still a need for my clients to not have to hack a command line or a text/xml
file. They are not programmers (they don't even use Windows's
CommandPrompt). When VPB is up and running, I'll just update the back-end to
reflect that.
XML is great way to save parameters in a cross-platform fashion.

Subject: Re: [osg-users] osgDem Windows Front-End
Date: Sat, 18 Aug 2007 16:54:23 +0100
FYI, I am currently changing the way that VTPB defines its source and
destination graphs. The source data is based on the
osgTerrain::Terrain/Layer classes and serialization. The destination
graph is not yet set but right now looks most likely to reuse PagedLOD
directly. The serialization will be supported by both .osg and .ive.
With the new work there will be several apps that can be run to
process chunks for the serialized destination graph. These will be
able to run multi-threaded as well as distributed across the network.
These apps will be nature be command line driven.
Defining the source data could be defined in an xml format, although
it won't really get you much over the .osg based source graph
serialization Follows is a current example:
osgTerrain::Terrain
{
name "puget sound"
ElevationLayer
{
CartesianLocator 0 0 100 100
Image ps_height_512.tif
}
ColorLayer
{
CartesianLocator 0 0 100 100
Images
{
ps_height_512.tif
ps_texture_1k.tif
}
}
}
I haven't modified osgdem to use the above as an input file format,
but this should be possible - one just loads the source data and then
traverse the loaded scene graph for its Terrain nodes, this could then
help build the old style source graph.
osgdem itself will stay largely untouched while I rewrite VPB, all the
new features will grow alongside it, and when they are ready and well
tested it should be possible to just drop osgdem.
In my planed work I don't have a GUI front end planned, exactly what a
GUI might need to encompass will depend upon how the final low level
code/apps work. Note that my VPB work will deliver have a system that
can do incremental and distributed builds, something osgdem can't do -
it just has to everything in a one pass.
The VPB work does mean that I can't recommend investing much effort
into osgdem. If you can spend a day mocking up a front end then fine,
but do expect it to be replaced within the next six months by
something that is quite different in the way it works.

[osg-users] ECW Image Files - Secret Tricks?
After compiling osgdb_ecw.dll, I've sucessfully loaded an ECW image file using osgViewer --image option, yet the same file produces the following message in osgDem: ERROR 4: `ortho_image_ecw\_1_8_scale2.ecw' not recognised as a supported file format. Aren't osgDem and osgViewer using the same image loading code? I must admit that I've had to modify the ECW file in photoshop before it could load (making it a power of two, lower-res, etc.). Anyone here with experience working with ECW files?

Antoine, I do not understand your last sentence: "However, if another plugin can, this error becomes a waring."

Re: [osg-users] ECW Image Files - Secret Tricks?
Antoine, You're right: the error is in GDAL. I tried GDAL_CONVERT.EXE and was greated with a similar error message. The GDAL.org page (http://www.gdal.org/frmt_ecw.html) mentions that ECW is an "option". So it looks like I'll have to compile my own version of GDAL and link with ERMapper's SDK to get osgDem working. - Nick - > >This error is coming from GDAL, probably wrapped into the osg_gdal > >plugin.

Re: [osg-users] ECW Image Files - Secret Tricks?
Antoine, So how do I make sure that the osgdb_ecw.dll plug-in gets called instead of GDAL? As it is, osgDem just stops (crashes actually...). I am not looking foward to recompiling GDAL ;( - Nick - I meant that OSG plugins are called in sequence, each plugin is trying to load the file and returns either an image handler or an error code. The way the GDAL plugin is trying to read a file is to open a GDAL dataset from this file. If it fails the operation returns a null pointer to the plugin but also displays an "ERROR 4" message. Then the plugin is returning an error code. If later on an other plugin is able to open this file, you do not need to care much about the GDAL error. Recompiling GDAL with ECW support would also work but would make the ECW plugin useless. > (PS: Peut-etre pouvez-vous m'expliquer en francais.

Date: Sun, 19 Aug 2007 12:52:31 -0400 Hi Nick, I think there is a misunderstanding of how osgdem works. The OSG readImageFile method, which invokes the plugins you are talking about, is not used in osgdem/VPB currently: it uses the GDAL library directly. I don't want you all to go down the wrong path trying to tweak OSG plugins that will have no effect. As far as recompiling GDAL to get ECW support, I would suggest trying to download the binary releases of GDAL included in the FWTools package ( http://fwtools.maptools.org/). The sight is down this morning, but should be back up at some point. It has almost all the optional plugins built for you and I'm pretty sure ECW is supported out of the box with those libraries.

Re: [osg-users] Documentation
Hi, As a recent newbie myself, here what I suggest you read: 1) OpenSceneGraph Quick Start Guide http://www.osgbooks.com/the_books/openscenegraph_reference_ma_2.html After you're done reading this, you can write basic scene graphs and start reading the source code. Free as a PDF download, or 13.50$US black&white hardcopy or 31.18$US for color hardcopy. 2) The OSG Source Code Examples A lot of questions are answered by reading through source code, starting with the viewers. Also take a look at the code of OSGEdit. 3) OSG Archive Search http://dir.gmane.org/gmane.comp.graphics.openscenegraph.user The best documentation is THIS mailing list. However, search this acrhive before you post any questions. I found that 70% of my questions were already answered in the email archive. 4) OpenSceneGraph Reference Manual v2.0 http://www.osgbooks.com/books/osg_refman20.html Once you get serious about OSG. Haven't bought it yet, but will do soon. 15.00$US as a PDF download, or 29.96$US. for hardcopy Hope this helps! - Nick - From: "maruti borker" <[EMAIL PROTECTED]> Reply-To: osg-users@lists.openscenegraph.org To: osg-users@lists.openscenegraph.org Subject: [osg-users] Documentation Date: Tue, 21 Aug 2007 18:52:35 +0530 I am a newbie in OSG , i find the D-oxygen generated documentation very limited as they dont explain what each function do or what the parameters mean .

Re: [osg-users] Tutorials
Zachary, I too have been programming OpenGL for while (10 years) and I find learning OSG to be quite humbling: very few of my OpenGL skills are immediatly transferable. OSG is very much like what the MFC ins to Win32, however, with MFC, there's always a way to use Win32 calls directly anywhere in the code. OSG does not allow this, which is more elegant, but makes it harder to "transition" from direct OpenGL. I understand that the documentation is at it's infancy, so let's give it time and try to contribute in making it better. - Nick - From: Zachary Hilbun <[EMAIL PROTECTED]> Reply-To: osg-users@lists.openscenegraph.org To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Tutorials Date: Tue, 21 Aug 2007 16:13:29 -0700 (PDT) The lack of documentation is very typical of Open Source software. I've looked at other Open Source 3D packages and they all have similar problems. Another problem they all have is limited support for dotNet. The creators of the different software I have looked at are typically more interested in adding features than they are in documentating the features they already have. If you are trying to learn it, it's a real problem because if a feature is not documented it might as well not exist. If you are working in a professional environment then the cost of a commercial package and learning it could be less than the cost of your time to learn a free but poorly documented package. With respect to OSG specifically I would say the Quick Start guide is good as far as it goes. There is much it does not cover however. The Reference Manual doesn't cover everything either, and much of what it does cover is simply a single sentence that is not necessarly meaningful. There are several example apps but they are not commented. I don't even know what some of them are supposed to do after having looked at them. Usually I can guess what is going on inside of them, but because of the lack of comments sometimes I don't really know why something is being done. I've written a lot of OpenGL, read the OpenInventor book, learned other 3D packages, and taken a graduate course in Computer Graphics. I still find myself having to guess at what a particular class or function is supposed to do or how a particular function is supposed to be called. I can imagine how difficult it would be for a novice to learn OSG. --- Nick Prudent <[EMAIL PROTECTED]> wrote: > I'm a newbie too and I disagree.

Re: [osg-users] Tutorials
Robert, By the way, the fact that it doesn't work like MFC is definitly not a criticisim. MFC had its share of problems. As I said, I prefer the approach taken by OSG. My only point for fellow newbies is to not give up and not expect to be up an running quickly because you know OpenGL. As the author, you clearly see the relationship with OpenGL. For a newbie, this relationship is not immediatly obvious. Here's my proposal for putting together tutorials without breaking the bank: YouTube Screen Casts. I recently learned a few PHP programming tricks from this serie: http://www.youtube.com/watch?v=Z5egpgAVxQI&mode=related&search= On the Mac, there are a few free solutions for doing this.

I am curious about your experience. The OSG deliberately has quite a thin OO layer on top of OpenGL, the granularity of state is follows pretty closely to that of OpenGL, the naming convention of OpenGL has almost entirely been honoured so glTexGen is osg::TexGen etc. OpenGL modes are just a pass through and can be set directly on a StateSet. One of my intentions with this thin mapping was the ability to reuse OpenGL knowledge and documentation. The big difference between using the OSG and OpenGL really comes from the OSG being OO and having a retained model rather than immediate model like OpenGL, but its a scene graph so its rather comes with the territory. I would have thought of all the scene graphs in existence the OSG is probably the most OpenGL centric in its naming/granularity. So its it just the OO or scene graph aspect that is the stumbling point?

Re: [osg-users] Fitting Viewer's Camera To New Scene
OK, I've tried redefining the manipulator directly and I tried with the main camera. Both methods fail to actually update the trackball's center & radius. Ex: m_rpMainCamera->setViewMatrixAsLookAt( vnew_eye, vnew_center, vnew_up ); or... m_rpTerrainManipulator->setHomePosition( vnew_eye,v new_center, vnew_up ); What's the recommended way to do this?

Re: [osg-users] Fitting Viewer's Camera To New Scene
Found this recent thread on changing the camera position:

The solution mentionned goes like this:

Thank you for reply
..now I can change the position of the camera.
I write here how I change the position
hope it can help:
ChangePosition (osg::Node *node){
const osg::BoundingSphere& boundingSphere= node->getBound();
osg::Matrix myviewMatrix;
osg::Vec3 eye = boundingSphere._center+osg::Vec3( 0.0f,-3.5f *
boundingSphere._radius, 0.0f);
osg::Vec3 center = boundingSphere._center;
osg::Vec3 up = osg::Vec3(0.0f,0.0f,1.0f);
myviewMatrix.makeLookAt(eye,center,up);
this->GetViewer()->setView(myviewMatrix);
}
Thanks!!!
Matteo

Needless to say, it didn't work either...For starter, there's no such thing as
osg::Viewer::setView(). I can't be the first person wanting to reset the camera
manipulators after loading a file...

Re: [osg-users] osgviewerMFC example crash in 2.1.8
I'm a newbie too and have had the same problem applying the MFC example to my own app. The problem was that wasn't giving a complete path. Use szPathName instead of szFilename from the MFC file dialog. Another way is to have the directory containning your data in your PATH environment variable.

[osg-users] osgDem UI
For those interested. I finally finished my little osgDem UI and it turned out pretty good. My clients are happy because they don’t have to deal with the command line. Actually, I find it easier to use too since it automatically validates long and complicated argument strings. You can see a screen shot here: http://www.sonographx.com/downloads/new_screen_generate_dem.jpg Here are the steps I took: 1) Build a command line string from the dialog controls and sends them to an osgDem process. 2) Redirects the console’s output into a read-only edit control so that osgDem progress can be displayed like Visual Studio’s build output. 3) Wait for the osgDem process to end and automatically load the result back into the main app’s viewer for a seamless experience. Hopefully, I’ll be able to reuse most of it when osgDem is replaced in the next few months ;) If anyone is interested in doing the same thing, send me an email at nick_at_sonographx.com (replace _at_ with @) and I’ll give you more details.

Inside my render loop, I'm updating some geometry based on external events. When I change a transform (rotation + translate), everything updates fines.
