Hi,
I discovered recently that it is a bounding box that is first calculated for
drawables.
Then the bounding sphere of nodes is the bounding sphere of the bounding boxes.

Whom at nVidia confirmed this built in latency and for what product
line?Inserting a glGet is inducing latency, not something built in.

Hello Sanat,

Well, trial and error can only bring you so far. If you compile OSG
yourself you can place breakpoints in y

Thanks for that. It helped me solve the problem.

Hello Sanat,
From the code you posted, you're creating 3 graphics contexts using the
same traits for all 3. This will obviously put all 3 on the same screen.
traits->displayNum and screenNum need to be set to the screen you want,
a different one for each context.
Hope this helps,

Hi Fred,
I had tried 0 and 1 before but that gave me the exact same behavior. So in your
application you have a different osgviewer window that displays in each screen
the moment your program starts running ?
I don't know if there is something wrong in the way I'm setting up my graphics

Hi, I've modified the osg billboard example and am examining the pixel size
computed from one of the billboard's bounding spheres.
I'm sure I'm missing something fundamental in my understanding of what's going
on, but I expected the pixel size computed by pixelSize() to correspond to the

Hi Jean,
You were right that my graphics card settings were not set to Configured
independently from each other (Dual View). I updated the settings in the nvidia
Control Panel and now have behavior similar to what you described with being
able to drag windows across screens, etc.
But unfortuna

Hi Fred,
A that explains why I don’t see errors...
I am still using vs2008 as VS2010 seems to leave the exe files in the bin and
lib folders whenever I build and I had funny linker errors last time ( a few
months back).
I might have a go at building flightgear later, let you know how it goes

I worked a bit on DAE plugin and as far as I know it should correctly export

Hi Martin,
to be precise, I don't see any errors when building OSG. The problem arise when
liking the application (here, it is FlightGear). I use 3rd party libs already
used for the VS2008 build. VS2010 is used to build OSG and FlightGear.

Well, Fred, if this is rendered within OSG then I guess that's exactly what
I want to achieve with respect to the atmosphere :-) No chance to get any
source sample for the texture precomputation stage I guess ??? :-)

Could it be that you need to update to the windows SDK either 6 or 7,

Interesting, I have just managed to build it VS2010 with no problems using 2008
libaries.
You could try using CMake to generate 2008 projects files and convert them to
2010 using VS2010, see if it makes a difference?

Recently Brad Christiansen uploaded some 3rd party binaries built with Visual

iostream problems when linking in OSG into my application in specific places

Actually, the atmospheric scattering effect you're pointing me at is what

If you have OSG 2.9.8, there is a new possible value for the face parameter :
osg::Camera::FACE_CONTROLLED_BY_GEOMETRY_SHADER

Hi guys !
The solution I suggested to myself, actually works !
So, if someone needs to render to a 3D image one day, one available option
is to attach slices of the target images as mentioned below.
To get those slices I used some code like (where z is the slice to render
to)

Hi Bob,
The 2 frame latency thing didn't smell right to me either, having been
used SGI machines extensively in the past. However after doing various
closed loop latency tests, I'm convinced that the latency of modern
Nvidia cards is higher than I would have expected. The 2 frame latency
