Hi all,
has any body used eclipse with osg. I tried using cmake but eclipse being an
IDE and not a compiler, I failed to get a breakthrough. I will be very
grateful to get guidance on this.
Thanx,
Felix

Hi
I use eclipse under Linux.
First you have the cmakeed http://www.cthing.com/CMakeEd.asp plugin to
write your CMakeLists.txt.
Then execute cmake ./path/of/your/project
Then Menu - Project - C/C++ Make Project, set your path, target ...
Then Control + B and Build !!!

Under WinXP, compilation ok, one small problem on osgconv, not a ble to
compress textures
osgconvd.exe --compressed cow.osg cow.ive
Failed to create pbuffer, failing back to normal graphics window.
Error: Unable to create graphis context - cannot run compression
Data written to 'cow.ive'.
HI Frashid,
Which version of the OSG are you using? The getRotate has gone through
many incarnations and quite a few months back that was a big round of
interations that settled on what is current in SVN - which meant
effectively reverting back to an older implementation.
Robert.

Hi,
I am using many different WinXP-Systems with OSG2.0, all having two
monitors and different NVIDIA cards.
Everything is fine but when I drag the OSG window to the other screen,
many systems produce the following error:

Hi Julian,
I don't have any direct answers, the best I can do is speculate, so here goes...
First up, two different graphics cards have two physcially different
blocks on memory and associated state that the drivers have to keep in

I am trying to visualize an intensity volume cube

plan to use shaders to test different parameters and shader code.
Because it is a huge volume file (~500MB), loading time is around 40
seconds... Anyway, what I want to do is
Hi Robert,
Thank you very much for your detailed answer!
But I am not sure if I discribed the problem in the right way...
In one single system is only one NVIDIA card with two displays attached.
So I guess the memory thing isn't that weird...

Hi Julian,
I have had similar problems on a project i've been working on, not involving

Choose performance quality settings.

Here we are again!

How can I change the stereo eye distance at runtime?, I've tryed

Hi,
I just got one of those SpaceNavigators from Siggraph and I thought it could be so nice to use it as an input device on OSG so... I've been looking for some low level calls in the OSG source code to have a hint where to start but it was useless, so can someone please give me a quick
Hi Pedro,
You needn't integrate the new device in an OSG centric way at all, you
can just poll the device yourself in your main loop and then do what
you want with it.
Potentially you could integrate it on an OSG centric way to make use
of the existing manipulators, and I've done this in the
Hi Mustafa,
You could simply load all the shaders into different statesets and then
switch between the state sets
(using osg::Node-setStateSet() I think ) at runtime. Then you don't have
to worry about adding/removing programs.
This is what we do for switching between different lighting models
Hi All,
I have just simplified the thread priority management in the

Hi Tobias,
If you are generating 90 views all within on frame then you have 90
cull traversals and 90 draw traversals, unless you scene is very
simple I would expect performance to be poor and will be particularly
CPU limited.
What CompositeViewer provides is not so much performance improvement
In our application, we are seeing CullVisitor::getCalculatedNearPlane()
return negative values.
We're using OSG version 1.1, but in looking at 2.0, I don't see anything
which would preclude the near plane from going negative. Should we be
clamping the near to a small positive number, or is

Not personally, but VRPN already supports several glove devices, and the

Thanks for your answer Robert.
The images I want to render are not bigger than normal images captured with
a single camera. But in my special case I use several cameras (beginning
from 16 up to 90) that render each only a small vertical strip of the scene.
The width of each strip depends on the

I just copied all NPS tutorials into the Wiki.
There's a number of things that still need editing:

-Addition of source zip files
-Addition of screenshots
-Addition of links to related stuff (Api reference, examples and User

Did you ever find a solution to your problem? I'm not seeing the same
