I can make you one, but that would leave no fun/exploration for you :)
Start simple and look at what osgviewer --image myimage.jpg does. Or
look at osgmovie. These examples load an osg::Image and place it onto a
quad.
What you need to do instead of loading the image, is creating an empty
image of the right size (and allocating memory for it - see the
osg::Image header for the calls) and then poke your values into it.
Attach the image to a texture and then attach the texture to a quad. You
can set the texture sampling for the texture (search for FilterMode and
NEAREST).
You can visualise this quad with your texture on in many ways, depending
on what camera you use to look at it. E.g. normal OSG camera where you
can spin it around, or you can put it in a HUD, or you can make an
orthographic camera.

[osg-users] Setting up a camera

But the camera doesen't look to where I want it to look at.

Position and orientation are changing constantly, but first of all I would be happy if I get the right view with some default values. I tried it with setViewMatrix() and setHomePosition() but nothing happens. Maybe I used it wrong but maybe someone can tell me how I have to realize it. Im using osg 2.8.1 with vc8.

Re: [osg-users] [osgPlugins] Build OSG using DCMTK
Hi Isa, From your description I can't work out what might be wrong. What you could try just pointing osgvolume at the directory that contains the separate dcm images. i.e. osgvolume DirectoryContainingDicomImages osgvolume will work out that you are referring directory and the dicom plugin will then treat all images within that directory as a single set of assocaited dicom files and build an 3D osg::Image from it, and then the osgVolume NodeKit will take this and do all the rendering for you.

Re: [osg-users] Setting up a camera
Hi Diana,
If you are controlling the camera from a user defined path or
simulation then you are best to not attach a camera manipulator to the
viewer and just set the viewer's master camera directly yourself. If
you do try to set the camera's view matrix yourself but still have a
camera manipualtor attached the value you set will be overwritten.
The osgViewer::Viewer by default will not attach a camera manipulator,
but if you call viewer.run() it will know assume there isn't anything
else settings the view matrix so will attach a camera manipulator as a
fallback to at least provide some interactive view.
For your own app I'd expect something like:
osgViewer::Viewer viewer;
viewer.setSceneDat(mySceneGraph);
viewer.realize();
while(!viewer.done())
{
viewer.getCamera()-setViewMatrix(myViewMatrix); // or use
setViewMatrixAsLookAt(..)
viewer.frame();
}
Robert.

peter.amst...@tseboston.com wrote:
Thank you for taking up this task. While not central to the mission of
graphics rendering, this feature will certainly make writing
applications around OSG a little bit easier for all of us.
My proposal for putting get/setUserValue convenience methods directly
osg::Object was based on the idea that the interface methods on
osg::UserDataContainer would accept the parent object as a parameter,
thus allowing a single container instance to be shared while providing
different data to different callers.
Um... I find this idea to be a bit awkward and only really at useful for very
specific usage model where you want a single custom UserDataContainer
to maanage all user data access for the scene graph. If you don't use
share a single UserDataContainer between objects then passing the
Object pointer is pointless and confusing - and this will be the default
scheme used by the vast majority of users.
Having multiple custom UserDataContainer that reference single central
data container is possible with the current scheme and wouldn't polute a
small numbers of users needs into the core classes.
Without that aspect, having
get/setUserValue on osg::Object still offers some convenience but also
introduces confusion and redundancy. Also, the ability to set any
osg::Object as the metadata container for any other osg::Object seems
like an invitation for chaos.
I think chaos is a rather overblown suggestion. The latest rev isn't an
ideal class layout, and as I've said it does feel awkward but I don't
ever expect anything other
than a tiny proportion of users to ever need to assign their own
UserDataContainer
let alone provide a custom UserDataContainer, I strongly doubt that
the ability to
attach a normal osg::Object as a user data container is likely to cause any
problems.
I think the pattern you describe as
object-getUserDataContainer()-get...() is acceptable, and is
perfectly consistent with the existing scene graph patterns in OSG
(setting up StateSets in particular comes to mind -- indeed recently
someone wanted to use StateSets as an ad-hoc metadata scheme).
My preference looks like:
class osg::Object {
// access _userDataContainer
osg::UserDataContainer* getUserDataContainer();
void setUserDataContainer(osg::UserDataContainer*);
osg::UserDataContainer* getOrCreateUserDataContainer();
// for backwards compatibility, defer to _userDataContainer
virtual get/setDescriptions();
virtual get/setUserData();
};
// abstract base class user data container
class osg::UserDataContainer : public osg::Object {
// returns self
osg::UserDataContainer* getUserDataContainer();
osg::UserDataContainer* getOrCreateUserDataContainer();
// throws exception/assertion or otherwise fails
void setUserDataContainer(osg::UserDataContainer*);
small note, I'm avoiding use of exceptions in the core, due to the
needs of embedded OSG usage - I don't
want different behaviours on different builds.
This seems very straightforward and avoids cluttering up osg::Object.
Is there a reason this approach was rejected, aside from a desire to
avoid the object-getUserDataContainer()-get...() pattern?
There is a little awkward issue of having a ref_ptr to sublcass of osg::Object
from within an osg::Object itself. To get around this you'd need to
define any subclass
as a nested class of osg::Ojbect, which... polutes osg::Object so it's
swings and
rounabouts with sticking the functionality in a subclass.
If a single user data container instance is referenced by multiple
nodes, will it be serialized once or multiple times?
Once, all osg::Object are serailized with an unique object id that is
written out
once then subsequent refrences to the that Object used the object id. When the
data is read back in the serializers just create on instance and then
share it.
This feature automatically will work for user data.
Can a user data container contain references to osg::Objects in the same
scene graph? Can the serializers handle this?
They are all just osg::Object's they all just get seralized out. The
osguserdata
example attaches an osg::Geometry as a user object and it gets serialized in and
out correctly. The only thing you'd need to be minful of is if a
UserDataContainer
holds a referneced to a paret - this would cause a circular refefence
that would
prevent all the objects in the loop and their children from being
deleted. This is
a standard issue for any ref counted data strucutre so isn't a
specific to user data,
it's just an issue users need to be mindful.
W.r.t you suggestion. Feel free to go ahead an implement what you are
thinking of,
reviewing stuff thta actually is implemented and working in header and
source files is
far more pratical than second guessing write ups in emails. The only
part I feel strongly
is the wrong way is the passing of the Object* to the access methods
in UserData,

Re: [osg-users] Computing Near and Far problem when viewing large terrain and small object
Hi Lv, If you have a scene with a very large distance range then depth precision is an awkward issue to deal with - the lower the near/far ratio the lower the precision. To retain precision you have to either push out the near plane or pull in the far plane, and they work as ratios so doubling the distance of the far plane is equivilant to pulling the far distance by half. You can juggle the exact distance computation but in the end if you need to render something very near and somehing very far you are forced to have a small near and large far values and with it precision issues. When you are in this situation the only practical thing to do is to depth partition your scene so that you render it into two or more sections. Basically you render the far section first then overlay the nearer sections on top of this, with the overlay sections clearing the depth buffer but not the colour buffer. In OSG 2.8.x there is an osgdepthpartion example that uses a series of in scene graph osg::Camera to set up the partitioning. It's quite clucky and awkward though so I wouldn't recommend. A much easier and flexible means of manage the depth partition is to set up multple slave Camera's in the view to do the job of the depth partitioning, this way the viewer configuration changes when you want to change to depth partition and the scene graph remains the same. In svn/trunk and 2.9.x there is support for creating slave Cameras to do depth partitioning, see the osgshadow example for this. Look for the section that does viewer.setUpDepthPartition(). Robert.

Re: [osg-users] Setting up a camera
Hi Diana,
I'm afraid I don't have the time to write up a full tutorual on maths
of setting view matrixes and matrix maths, the topic has been covered
lots of time by the community so I'd recommend you have a look through
the archhives.
As a quite note, I'd mention that in OpenGL and the OSG the view
matrix translates the world coordinates into the eye coordinates, and
eye coordinates are +ve X to the right, +ve Y up, +veZ out from the
screen. While in vis-sim the convention is that world coordinates of
the scene have +ve X to the east, +ve Y north +ve Z up. Please note
that the scene is in world coordinates, and the view matrix transforms
the world cooridnates into eye coordinates, the view matrix doesn't
position the eye into the scene but the other way around - this is
important as it's the inverse matrix of a matrix that positions an
object in the scene in world coordinates. This later point is
probably where you have gone wrong.
I won't dive in any further as teaching users about maths is not my
role - I have plenty of other work to do. Please spend some time
looking into the background maths, there are a huge number of articles
on the web and posts on osg-users over the years.
Robert.

Subject: [osg-users] Shaders and Nvidia 275.33 drivers problem
Hello
I have win7 x64 nvidia video card
I found strange problem after update to version 275.33 of nvidia drivers.
I see artifacts with shaders, i tried to find why.
Part of shader uniform variables are not work correctly.
i try to debug it with gdebugger and i noticed non-initialized values in part
of uniforms.
file src/osg/Program.cpp lines 672-673
Code:
_extensions-glGetActiveUniform( _glProgramHandle,
i, maxLen, 0, size, type, name );
Later i found that names of array variables coming with [0]. example -
%name%[0]
i tested with 266.58 they coming without [0]
as result in _uniformInfoMap[Uniform::getNameID(reinterpret_castconst
char*(name))] = ...
we recording values with [0].
file src/osg/Program.cpp lines 213
Code:
inline void apply(const Uniform uniform) const
{
GLint location = getUniformLocation(uniform.getNameID());
if (location=0)
and here we can't get right location
i fix it, please look patch
Code:
--- a/OpenSceneGraph/src/osg/Uniform.cpp
+++ b/OpenSceneGraph/src/osg/Uniform.cpp
@@ -611,13 +611,13 @@ unsigned int Uniform::getNameID(const std::string name)

-UniformNameIDMap::iterator it = s_uniformNameIDMap.find(name);
+UniformNameIDMap::iterator it = s_uniformNameIDMap.find(name.substr(0,

+s_uniformNameIDMap.insert(UniformNameIDMap::value_type(name.substr(0,

}
But i don't think that is a good solution.
Thank you!

Re: [osg-users] [osgPPU] Render lower Resolution with unitOut than wandow / fullscreen
Hi All, @Ricky, it works for me as expected now. First I attach a new viewport with e.g. half res of my output window, and attach a texture with the same half res to the Color Buffer of the Camera. This can be done with different Cams and resolutions, if you have some funky pipeline. camera - setViewport( new osg::Viewport( 0 , 0 , halfResWidth , halfResHeight ) ) ; camera - attach( osg::Camera::COLOR_BUFFER0 , textureColor ) ; // has also halfResWidth/Height At the end of the pipeline I tell the unitOut not to use any camera viewport as ( size ) reference, and add another Viewport with the full resolution of my output window. unitOut - setInputTextureIndexForViewportReference( -1 ) ; // Don't use any Camera Viewport as reference unitOut - setViewport( new osg::Viewport( 0 , 0 , fullResWidth , fullResHeight ) ) ; That's it. @Art With out of Sync I meant that the visual scale of the Glowed scene had not the same size as the visual scale of the non glowed scene. My mistake was, that I tried to scale up the viewports that were attached to the cameras ( main and glow ), but should have done that with the viewport attached to unitOut. Everything is working fine now :-) But still a good Debugging Hint, didn't know that till now.

Re: [osg-users] Setting up a camera
Hi Diana, I find it pretty convenient to use Code: getCamera()-setViewMatrixAsLookAt (const osg::Vec3 eye, const osg::Vec3 center, const osg::Vec3 up) for setting up the view matrix, it was one of Robert's suggestions but I thought I'd re-emphasize it. Vec3 eye will be the position you're getting from the server. Vec3 center will be the point the camera is aiming at - it doesn't have to be the center of the scene, if you are given or can calculate the direction vector the camera is pointing along, (0,1,0) for example to look along the y-axis, you can add that to your eye point and use the result as center. Vec3 up orients the camera, think about taking a photo in portrait vs landscape vs some other angle. To start if you know the coordinates of some point in the scene, you could use that as center and just play with changing eye, the camera will always look at the same point (center) but from different places. After that, you could then work on calculating center based on the orientation you're receiving from the server.

[osg-users] OSG Qt integration

Re: [osg-users] OSG Qt integration
Hi Juan, I can't comment on the possible memory leak with using Qt. What I can say is that quite has bit has changed in the OSG and it's Qt integration since 2.9.8 so I would recommend grabbing the svn/trunk or 2.9.15 dev release and building this directly yourself. If you still see issues then it would be best to implement a small example that illustrates the problem, such as modifiying one of the OSG's Qt examples, so that others in the community can see if they can reproduce the problem, and if there is a bug we can look into it. It doesn't make an sense for us to go chasing up and old dev release though, all dev work goes into svn/trunk, so you'll need to move to svn/trunk or the latest dev release so we can all work on the same base.

Re: [osg-users] Setting up a camera
Diana,
First off, I don't see where you're setting the view matrix for the
camera in your code below. You compute the transform, but you'll need to
attach it to the camera.
Since it looks like you're navigating on a sphere, I would try the
following in your while loop below...
osg::EllipsoidModel convert;
osg::Matrixd position;
osg::Matrixd t_matrix;
convert.computeLocalToWorldTransformFromLatLongHeight(lat,lon,height,pos
ition);
t_matrix = position;
t_matrix.invert(t_matrix);
osg::Matrixd rotate2YUp;
rotate2YUp.makeRotate(-M_PI_2, osg::Vec3f(1.0, 0.0, 0.0));
t_matrix *= rotate2YUp;
viewer.getCamera()-setViewMatrix(t_matrix);
viewer.frame();
Of course, I'm assuming that you have all the other camera state (i.e.
projection matrix, viewport, etc.) set up correctly. The above doesn't
include an orientation transform so you will need to add that. When you
do, it will be concatenated with the position matrix.
Make sure that lat, lon are in RADIANS when you call
computeLocalToWorldTransformFromLatLongHeight. Height is usually in
meters.
One more thing...it would probably be best to move the code outside of
the while loop and place it in an UpdateCallback...

The 275.33 Drivers are not good I personally would avoid like the plague, they
are causing all sorts of problems for people

Subject: [osg-users] Shaders and Nvidia 275.33 drivers problem
Hello
I have win7 x64 nvidia video card
I found strange problem after update to version 275.33 of nvidia drivers.
I see artifacts with shaders, i tried to find why.
Part of shader uniform variables are not work correctly.
i try to debug it with gdebugger and i noticed non-initialized values in part
of uniforms.
file src/osg/Program.cpp lines 672-673
Code:
_extensions-glGetActiveUniform( _glProgramHandle,
i, maxLen, 0, size, type, name );
Later i found that names of array variables coming with [0]. example -
%name%[0]
i tested with 266.58 they coming without [0]
as result in _uniformInfoMap[Uniform::getNameID(reinterpret_castconst
char*(name))] = ...
we recording values with [0].
file src/osg/Program.cpp lines 213
Code:
inline void apply(const Uniform uniform) const
{
GLint location = getUniformLocation(uniform.getNameID());
if (location=0)
and here we can't get right location
i fix it, please look patch
Code:
--- a/OpenSceneGraph/src/osg/Uniform.cpp
+++ b/OpenSceneGraph/src/osg/Uniform.cpp
@@ -611,13 +611,13 @@ unsigned int Uniform::getNameID(const std::string name)
static UniformNameIDMap s_uniformNameIDMap;
OpenThreads::ScopedLockOpenThreads::Mutex lock(s_mutex_uniformNameIDMap);
-UniformNameIDMap::iterator it = s_uniformNameIDMap.find(name);
+UniformNameIDMap::iterator it = s_uniformNameIDMap.find(name.substr(0,
name.find([)));
if (it != s_uniformNameIDMap.end())
{
return it-second;
}
unsigned int id = s_uniformNameIDMap.size();
-s_uniformNameIDMap.insert(UniformNameIDMap::value_type(name, id));
+s_uniformNameIDMap.insert(UniformNameIDMap::value_type(name.substr(0,
name.find([)), id));
return id;
}
But i don't think that is a good solution.
Thank you!
Cheers,
Alexander

[osg-users] OSG based aplication nominated in CG Architect Awards
Hello people! Lot of time without writing anything here. Anyway I've been using a lot OSG in almost all my projects. I just one to tell you that one of them have just been nominated in the CG Architect Awards 2011, for Best Real-Time Application, and is completely based on OpenSceneGraph. It's called Spatial, volumetric and sectional analysis of the Cathedral of Santiago de Compostela. http://3dawards.cgarchitect.com/nominees/view/realtime/1099 So never is late to thank the community, because without you this projects are not possible. -- *Alberto Jaspe* *Computer Graphics RD Guy* http://albertojaspe.net ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [osgPlugins] Build OSG using DCMTK
Hi, I run it using osgvolume dir of dcm files as you suggested... this is the link to the dcm data https://jshare.johnshopkins.edu/pkazanz1/Skull-2mm.zip I dont seem to understand when i render only one of the files, how it looks right, except that it looks like a part of that image... but the whole volume looks wrong... Thank you soo much for helping me out. ... Thank you!

Re: [osg-users] 2.8.5 release tag
The first thing to do is update the wiki, and generate the official zip distribution. I have made a zip file by exporting the subversion tag given, and I can upload it somewhere if that would help. I'm in the process of creating rpm files for use on Fedora 14, x86_64. I will also soon make rpm files for Centos 5, which should also work with Red Hat Enterprise Linux. I'd be willing to help edit the wiki but alas I have forgotten (again) how to get access.

Thanks, Robert -- I just tried to log in to the wiki so that I could get the wiki markup source for the 2.8.4 press release to use as a template: http://www.openscenegraph.org/projects/osg/wiki/News/Press/OSG2.8.4 However, I got an error when I tried to log in to the wiki: Trac detected an internal error: OperationalError: database is locked If you could resolve this issue and/or send me the wiki markup source, then I'll write up the announcement and post it. -Paul On 6/6/2011 11:55 PM, Robert Osfield wrote: Hi Paul, On Tue, Jun 7, 2011 at 2:14 AM, Paul Martzpma...@skew-matrix.com wrote: Hi all -- OSG 2.8.5 is now released.
