Re: [osg-users] preDrawCallback?
I don't think GDI is buffer-savvy, so there's no way to tell it to draw into the back buffer. (10 years ago, when HP made their own graphics cards, we developed a solution for mixing GDI/Xlib with OpenGL, and it was quite flexible. No one else ever implemented such a scheme. As a result, GDI/Xlib rendering into an OpenGL window is unsupported and will produce undefined results.)

[osg-users] [beginner question] How to render from custom camera?
Hi everybody,
I am using osgART for an AR project I'm currently working on, which joins osg
and ARTookit -- but since my question is rather regarded to osg, I'm asking you
folks...
In osgART the developers seem to create a custom camera they place inside the
scenegraph, under a transform node which continuously gets updated regarding to
ARToolkit tracking results.
Well, I'm using a CompositeViewer to create two views in seperate render
windows rendering the same scene. Only one view is showing the scene updated
from AR tracking, the other one is supposed to show the scene from a position I
want to be able to modify in my code.
For consistency reasons I really want to create the camera for my second view
the same way osgART does in the first view, this looks pretty straight forward
in their code:
Code:
osg::Camera*
Calibration::createCamera() const
{
osg::Camera* cam = new osg::Camera();
cam-setRenderOrder(osg::Camera::NESTED_RENDER);
cam-setProjectionMatrix(_projection);
cam-setReferenceFrame(osg::Transform::ABSOLUTE_RF);
cam-setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR);
return cam;
}
In the example code which is provided the so created camera simply gets added
to the scene graph in some position (below this AR-transform node I mentioned
above) and that's it. (Question aside: What happens to the default camera in
this case? And: Can I get rid of it/replace it?)
If I do this the exactly same way my view seems to continue to render from the
default camera created within the view instance. Do you have an idea what I am
missing there? I debugged into osgART and couldn't find some view.addSlave() or
something similar.
Unfortunately I'm a little overstrained by the tremendous extent of osg, the
available guides seem to be scattered about several websites, wikis, tutorials,
etc. while the actual (doxygen) documentation is very sketchy and little
illuminating. as you might know this makes it very difficult for beginners to
get into it. I found examples using osgProducer::Viewer, or Producer::Camera,
slave cameras and many funny things I wonder why there have to be so many
different ways of implementing, but I really would like to keep my way of
creating this cam consistent to the way it is done in osgART -- there really
has to be a very simple way to do this in a clean way but I cannot find it.
Thanks for reading through all of this, and thanks in advance for your help.
PS: A few weeks ago I tried to replace the default viewer camera by the custom
camera to not have a camera that is not needed anyway but I failed finding a
way to do this. Is this possible anyway?
PPS: What is it about this default camera anyway? It looks kind of weird to me
that the default camera is not part of the scenegraph, after all it's a node
like everyone else. Or did I get something wrong here? Maybe someone can point
me to a place where this whole osg-architecture is explained in detail so this
is clarified once and for all IN A COMPACT WAY? (If I had enough time, I would
enjoy reading into everything I can find but unfortunately I haven't...) Every
time I debug into osg::Viewer I wonder how this all works together...

Re: [osg-users] .osg file format specification?
You should search the archives, this has been asked before. There is no spec, it is a text dump of fields in OSG classes. To see what info is read and written, examine the source code in src/osgPlugins/osg. The best way to create a plugin as you describe would be to build a scene graph, then call osgDB::writeNodeFile and let the existing code create the .osg file for you. I have created a similar plugin for PolyTrans. And I also believe someone has written such a plugin for Maya, so you might want to do a search of the Web or this mailing list before you undertake development.

Re: [osg-users] [beginner question] How to render from custom camera?
Hi Real --
The code you quoted is rather odd in that it doesn't set the View matrix. I
can only assume that some further Camera configuration must be done
elsewhere.
I'm also not sure why that Camera node would be placed as a child under a
Transform node, because the Camera reference frame is set to ABSOLUTE_RF,
which basically causes it to ignore the effects of any parent
transformations.
Perhaps this custom Camera classis taking the accumulated transform from its
parents and incorporating it into a View matrix that it sets every frame?
This is just speculation.
Not sure why your own code wouldn't work. If, as I suspect, more Camera
configuration is done on your AR Camera elsewhere, and you have failed to do
similar configuration to your Camera (such as set the View matrix), then I
would expect to encounter some problems.
Regarding the documentation, this has been discussed before. Search the
archives. In summary, someone who wants good docs needs to step forward and
fund it. I would gladly take on such a client.

In short: Quat * Vec3 is written in code as a post-multiply, but the result of the operation is as if a pre-multiply was performed. The attached test app also shows the problem (more on it later). [1] http://thread.gmane.org/gmane.comp.graphics.openscenegraph.user/21003 and http://thread.gmane.org/gmane.comp.graphics.openscenegraph.user/33099 What doesn't work? There are many examples that can be constructed of where a mathematical expression usings quats and vectors would not provide the expected results. See also [1]. The easiest one I could come up with is this: ((q1 * q2) * v) != (q1 * (q2 * v)) Why are there not more complaints? Well I curse this all the time, but not for the same reason. For me it's q1 * q2 that's annoying as I see it as the opposite of what I expect from the mathematics of applying a quaternion to a vector but then therein lies the problem. Using operator* for matrix multiplications is fine as that mirrors precisely what you are doing with the matrices mathematically. Using operator* for quaternion multiplication is a loose analogy since you are actually doing q*v*q' mathematically when applying q to v. If you have two rotations, q1 followed by q2 then you would get q2*q1*v*q1'*q2' mathematically and so I expect the interpretation of operator* to allow me to write q2*q1*v in code. Of course that's just my interpretation and what I'm effectively saying within that interpretation is that it's quat * quat that is wrong but there's no way in the world you can swap that now! :) Alternatively you could drop osg::Vec3::operator*( osg::Quat ) altogether and have osg::Vec3::apply( osg::Quat ) or osg::Vec3::rotate( osg::Quat ). I've used math libraries that do it this way (and where vec::operator*( quat ) is just that i.e. the mathematical multiplication rather than the full blown rotation. I guess it depends on whether you value the brevity of operator* over the underlying mathematics. If operator* is still going to be used for applying a quaternion to a vector then I support the idea of making the multiplication orders consistent between quat/quat and vec/quat as per your proposal. Making it consistent with OSG's row-major matrix multiplication is probably easier for coders who are not concerned with the details of the maths (and as I noted above it's not a workable solution to swap it now anyway). Whatever happens I second the comment of Tanguy Fautre who asked for it to be documented clearly somewhere. :) Anyway I hope you don't mind me chipping in. It certainly is interesting that there hasn't been more discussion. Maybe people just do what works and leave it. ;) Paul Fotheringham. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
