[osg-users] Fwd: creating widget for Qt
Hello Ivan, In the pro file do i have to include OpenGL module or just the library linker for Openscenegraph will suffice Regards Sajjad -- Forwarded message -- From: Iván osgfo...@tevs.eu Date: Wed, Mar 4, 2009 at 11:27 PM Subject: Re: [osg-users] creating widget for Qt To: osg-users@lists.openscenegraph.org Hi Sajjad, Personally I create the whole interface in Qt designer and leave the OSG widget/s integration in the initialization code. About the header file, I 've separated the code from the original OSG file in my own files (.h and .cpp) As you can see in the Qt sample you have different options to render OSG in a Qt widget. This works for me except for some warnings because of rendering out of QPainter events, but I will deal with this later :) I hope this help you in some way, Iván. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=7966#7966 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [build] Unreckognized Commands
I did not used express, a similar problem happend to me when I had an osgviewer of one version using a dll from another. Check if you have other osg dll in your path and check if your dll and your exe are all debug or all release. You can also use depends to check the dll loaded at runtime. If you are using svn head, try to switch to 2.8 release and rebuild from scratch to see if the problem persist. Hope it helps Adam Wise ha scritto: Good and bad news: The good: I can access osgviewer. The bad: It crashes every time I try to use it.

Hello,
I wonder if there's still support for osgCal2.
Not much support since I don't use osgCal for some time. I don't read

you have some questions it's better to CC me for faster answer.
I'm currently running into a problem where I believe that osgCal may not be
doing something right:
void
HardwareMesh::releaseGLObjects(osg::State* state) const
{
osg::Geometry::releaseGLObjects( state );
mesh-displayLists-releaseDisplayLists( state );
}
I didn't find such code in current version, maybe you need to run `svn update`.
The mesh looks like it's a shared object, and releasing its display lists
kind of messes with the other instances of the same model.
Mesh display lists would be recreated, but I didn't tested osgCal
behaviour in case of viewer restarts.
I haven't been able to update my subversion directory from the svn server,
so does anyone know if it's still maintained?
svn repository works, maybe it was temporal sourceforge.net problem.

Re: [osg-users] [3rdparty] about osgCuda
Hi Ufuk, actually we plan to release a first version of osgCompute (which includes osgCuda) within this week. We will announce the website and the svn information here in this fabulous forum/mailing lists. In general there are a couple of ways to connect osg and cuda. You might think of using a RenderBin or a leaf node. However, you can take the Cuda Runtime API or the Driver API. Also the cmake scripts have to find the cuda includes and libs for proper compiling/linking. I am sorry that I have no other starting points for you. Maybe it will also help you to have a closer look at the Cuda SDK examples.

Yes, in fact it's a patch we applied ourselves, sorry...
The mesh looks like it's a shared object, and releasing its display lists
kind of messes with the other instances of the same model.
Mesh display lists would be recreated, but I didn't tested osgCal
behaviour in case of viewer restarts.
The underlying problem is documented here:
http://sourceforge.net/tracker/index.php?func=detailaid=1871805group_id=79240atid=555954
If I destroy an animated mesh and create a new one, I get black pixels
instead of my character's texture. This doesn't happen if another
character with the same mesh exists, so there is a problem with the
sharing of a model. If it is reused, the displaylists may not be cleaned
properly but I'm not sure what exactly goes wrong. I think cleaning the
displaylists of the mesh if the mesh is not shared by anyone else should
work, but the destructors get called too late for some reason.
I haven't been able to update my subversion directory from the svn server,
so does anyone know if it's still maintained?

Hi Carlos, Have a look at the osgmovie example for guidance, it'll boil down to reading a image, and assing to the a textured quad.

[osg-users] Forum users rare uses signatures, which is a pain tracking who's who
Hi All, With the advent of forum.openscenegraph.org developed ably by Art Tevs we have a great new avenue for users to choice whether they prefer forum or mailing list for support... which is great but... for mailing list users the posts from forum members have become rather impersonal, with all too cryptic usernames, something that can happen with emails too but is happening far more readily with forum members. Once postings starting loose who they are from they also loose the self regulating and personal nature to them, and it makes bad tempered posts more likely, either at original source, or in response. Making the effort to make your posts more personable and friendly is a great help to general health of the community, signing posts might seem like a small thing, but it really doesn't make a huge difference - it's a big step to making exchanges friendly and positive. Dozens of times of the last month I've have to ask users to make this tiny little bit of effort, but with more forum users this is becoming a uphill struggle. Might there be a technical solution to this? Does the forum software have the data to properly sign emails, or to put a proper name in the address? Either way a solution of some kind really needs to be found. In the meantime I can enforce my own little mechanism of just ignoring all posts with a cryptic author name... so if you want support you'll need to make the effort to be curtious. Thanks in advance for all your friendly signatures ;-) Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Forum users rare uses signatures, which is a pain tracking who's who
Hi Robert, Paul. Ok, let me first answer Roberts questions and then coming to Paul's. @Robert: Yes, I was also afraid if forum becames more wide used, so that the community might became more anonymized then by using mailing list. I noticed same behaviour on any forum. Users are just very lazy and do not either add proper realnames, or any signature. Forum does already do one thing against that, so that it force users to setup a real name before they can register. However you can not control, what they are writing in the Realname field during the registration process. Hence, I am not sure, how this issue can be solved at all??? @Paul: The main reason because all of forum users post have the same senders adress is that people not even able to manage to read the READ ME FIRST Announcement on the forum! The problem is, that you can only post on the mailing list if you register yourself with your own email adress on it. However as forum users might be not registered on the mailing list at all, their posts could never reach the mailing list. In the beginning I just forced every user to register with the same email adress as on the mailing list. But new users just ignore this. As I said they even ignore what I have written in the READ ME .. on the forum, which has to be taking into account when using the forum. Hence new users posted messages on the forum, but they were not forwarded to the mailing list, because users' email adress was not registered on the ML. Hence the only solution was to declare some default email adress which can be used as senders adress for every user. However this can be disabled by every users in their profiles, but I am afraid that this will almost never happen, because 90% of users not even read the READMEs :( !!! To solve the issue with the same sender's email adress one has either to allow to post from every mail adress onto the mailing list, which will open the door for spamming. Or to create some interface for the mailing list which can be used by the forum to post onto it, however this would require some research and development of such an interface. Maybe somebody has an idea about that? cheers, art -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=8541#8541 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Forum users rare uses signatures, which is a pain tracking who's who
2009/3/16 Roland Smeenk osgfo...@tevs.eu You mean forum posts like this??? We'll at least you have a name that others can get an idea of who you are... Most forum users don't to seem to have any human readable user name at all, and don't both to sign their names. Email/forum messages really aren't much different than other written forms of communication, it's basic courtesy to actually sign what your write to other people and really helps make written exchanges more civil. It's a sad fact that electronic community can lead to people becoming so lazy that even basic courtesy is ignored, they might not mean to be rude but without any attempt at communication at personal level is really hard sometimes not to read into some posts that posts the author simply being a self-centered and rude. I raise this as an issue because with electronic communication unproductive flame feast can easily erupt, it only takes one or two posts to come across in an aggressive tone for replies to descend to the same level and so the spiral of community descends. If we can avoid the communication getting impersonal in the first place then we stand a better chance of keeping communication positive. Sure there will always be some posters that some of the time will be genuinely rude just because they are that type of person, or a normally good natured person at the wrong time of day, this is part of life, none of us are perfect. You want these posts to stand out like a sore thumb, the exceptions to the daily grind of life. If most posts start sounding like the author is not making any effort to be civil then it's hard to keep general good natured tone up.

[osg-users] Separate sub-graphs of the same scene
Hello, I'm trying to merge two sub-graphs to the same image. It doesn't work so well, so I'll try to explain what in general I'm trying to achieve, then my not working so well solutions, and then the questions :-) So, in general I want to replace an object (A) in the scene with another object (B) on some condition. The object (B) is some pixels which are lit up. The important thing is to keep the 3D scene distance from the camera for both objects, so if the object is obscured by another, then both (A) and (B) will be obscured, and if some other object (C) is obscured by (A), it will still be obscured by (B). Object (B) might be partially transparent. Not working so well solution 1: Have switch for (A)/(B). The position of (A) is multiplied by view-projection matrix, the result is pos'. (B) is a set of points which their vertices are pos' with (x,y) replaced by the pixels I want to lit, and the new positions are multiplied by the inverse-projection invers-view matrices. This solution had problems with setting the right pixels. Not working so well solution 2: Object (B) is a set of pixel under ABSOLUTE_REF orthographic projection with (x,y) of the pixels I want to lit and z is the negative distance between (A) and the camera. This solution has the correct pattern of the lit pixels, but the Z order doesn't seems to be correct. The implementation of solution 2 is to add camera with ABSOLUTE_RF and orthographic projection. View is identity. I set the clear mask to 0 since I don't want the Z-Buffer to be cleared. (opposed to huds and that kind of implementations). I used the osgviewer to put the cow at 0,0,-300 under absolute_rf, and a point at 0,0,0 under separate camera with orthographic projection, and the point was hidden by the cow (which is a mistake). I thought that I might need to set the zNear/zFar of both camera's to be the same, but in this simple example it shouldn't matter since the point Z is zero… So first, do I have to set the zNear/zFar of both camera's to be the same? Any ideas whats going wrong? Other solutions for the problem? Btw, I tried to replace the points by quads under orthographic projection. The results were the same.

[osg-users] Image Resolution in VPB
Hello, I'm using VPB to generate a terrain database with 2ft resolution elevation data and 1 ft resolution imagery.

It seems that if I could tell VPB to pad out the extents of my input data to a power of 2 that should work as well. I don't care if its black or garbage or whatever. Would the -e option do what I want if I specify extents larger than the input data? I'm about to give that a try but it takes about three days for this job to run to completion, so I figured I would ask if anyone has tried to do the same thing. Thanks for any insight.

We don't need to exact name but we need a name, it's a basic principle of human communication that you need to know who saying what to whomn, if all 2000 of us took up the name John Smith then it would be a pretty hard to keep up an semblance of humanity. It would be quite simply impossible to keep track of things. At personal level, I think it's dishonest not to being open about who you are. Alas it's fact of online life that people to hid their identity, sometimes their are valid reasons but rarely in the case of community such as ours. While you can subscribe to lists/forum and assume any name, not assuming any level of human readable name is just plain awful for everybody else in the community that has to deal with such individuals. As soon as you dive in you are part of the community, and this community has to be a healthy place to hang out for everybody involved, and if you want help from others in the community surely you want to maximize the chances that others will help you. Being polite, open and curteous is the best way to achieve good support, one big element of this is telling people who you and how to you liked to be addressed you. As an experiment, for all you face to face social meetings were you'd normally give your name, don't bother giving your name, just say sorry I don't tell people my name. Also instead of addressing people with their name just say what you want to say to everybody and if the right person doesn't respond just speak louder, and keep speaking louder until you get the response you want. At the same time avoid any eye contact in all conversations. I'm pretty sure you'd start loosing friends + associates pretty quickly. In electronic communication we have no eye to eye contact. We have no tone of voice to pick up. We have no face expressions to read. We have no hand guestures. When we talk we talk with many thousands of people are potentially listening. In this context perhaps you might see that you have to cling on to what parts of our humanity make communication successful - yep it's know who's talking and who they want to talk to is fundamental.

For Benoit having a single master Camera track different CameraView nodes in the scene might well be the most convinient way to manage things.

Hi all, I'm not at my msvc90 machine right now so can't test until tomorrow. gunzip on linux reports failures to. I've been using 7-zip for all the packages for msvc90 so I have tested some other packages in that folder. Among others openscenegraph-all-...Release.tar.gz which seems to work with linux gunzip and tar. So - I'll repack, test and submit tomorrow.

Re: [osg-users] switch between two camera
Hi Robert, I also meet the same problem, I have 128 snapshots of particles, and I want to use those 128 shapshots to make an real time animation. First thing I tried, was using a update callback function and bind it on my geode, everytime I just updated all positions of particles. But obviously it was quite slow. Then I tried to use two view, and each one has it's own camera, and render two snapshots in the same time. Well, it works, but still very slow. Then I tried to use one view but two cameras, and load three snapshots in the same time, two below two caremas, one below my Root. because I do really need to update it. And link the right snapshots while I need to render it. Somehow it is still slow, and while it switches snapshots and I use trackball, it is played not fruently. So my question is, basicly I need to render un-structed points dataset, and I have a lot snapshots, do you have any idea how can I make an realtime animation fruently? Looking forward to your reply and thank you very much.

Re: [osg-users] Forum users rare uses signatures, which is a pain tracking who's who
Hi all, And what about manually banning (temporarily) from the forum those who don't respect basic rules? That could be simple: 1. Warn the user if the real name isn't explicit enough 2. Ban until real name is changed (The user could still use the mailing list) I'm pretty sure people would not to dare keeping an unclear name for a very long time... That would require a bit programming but that would not be very difficult I guess. I just hope this isn't too radical! And another idea could be to get a reminder each week (or month?) if the email address isn't set (or is the default one). Thoughts?

You can't force them to give their actual Real Name, but I imagine most people wouldn't lie on that, even if they don't use their Real Name for their forum ID. Hi Bryan, actually printing out an automaticly generated signature wouldn't change anything, because users' real name values are already used in From header of the generated email. Hence if user X does call himself Mister X, then the email heaer looks like this: From: Mister X Even if there will be now a forced signature the signature can still not give more information that user has given. The signature could look like this: - Forum user: Mister X (X) So the one thing I could add is mister X's used email adress and nothing else, because there is just no more information available. art -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=8548#8548 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
