Hi J-S,
Do you have an example which I can try. Then I can give it a try here,
on a couple of machines.

Have a look at the osgdistortion example or the
osgViewer::setUp3DSphericalDisplay() code - its sets up six slave
cameras which rendering into a texture cube map, and then a final
slave camera to render the final distortion correction mesh.

No one have already had this problem ?
Thanks.

You need to use extract the rotation part of the the master camera's
view matrix to give you
Hi all.
Im +working in a project where we are rendering objects on Center of Earth
(ECC) so we have a z-coordinate of 6.7E6Meters.
So obviously we need to transform objects close to origo to be able to
render them.
I noticed that I got quite a few anomalies in the rendering,

HI Anders,
It isn't possible just to remap the Vec3 typedef from Vec3f to Vec3d,
as you have found the their are many places that explicitly rely on
floats. Places like BoundingBox and BoundingSphere could potentially
be moved across to use Vec3d rather than Vec3f, and the way to do this
would
Is there a function to stop an osgParticle system from releasing particles
after a certain number or particles have been fired or perhaps a certain amount
of time has passed without creating a custom class?

Hi Vincent,
I don't use this feature but if you attach a small example
that triggers that behaviour in your machine I would test it
on mine (x86_64,Linux 2.6.22 , OSG SVN HEAD).

Nicolas.

Hi Nicolas,
this is my code :
//SCRIBE MODE
osg::ref_ptrosgFX::Scribe s = new osgFX::Scribe;
s-setWireframeColor(osg::Vec4(color.x(), color.y(), color.z(),
1.0f));
s-setWireframeLineWidth(edge_width);//DO NOTHING ?!
Hi,
I think it doesn't exist yet... (perhaps I make a mistake writing this)...
But counting time left before stoping the particlesystem is not very
difficult... just make a time difference and switch off your particleSystem
(or remove it) from the graph...
Vincent.

Hello Raymond,

You can just add
viewer.addEventHandler( new osgViewer::ThreadingHandler() );
to the osgshadow example (around where the other handlers are added) and

Hi, It works fine on my configuration, so it does not look as a code problem
nor an OSG bug.
Of course I did change edge_width and color.x/y/z for a float numbers but
apart from that I used the same code.
Are you sure edge_width is set to the value you want? If yes may be the is
a bug in the
Thanks for testing :)
I'll see what it can be, if it depends on drivers or not...

I'm looking for a way to export from OSG to 3DS format.
I notice that OSG does provide a plugin for loading 3DS, but does not
appear to support the output of that format.
Looking at the sources for the 3DS plugin, I noticed that there is
code that may support part of the process of 3DS output
Yes and no.
Unfortunately in general physical simulation you don't have the luxury of
culling away things that are not visible.
So even for an airplane flying over vast areas, the visual part around the
airplane can still be handled using float, and objects further away require
less precision,
Hi Chris,
As you have found out there is no write support in the 3ds plugin.
The 3ds format is not a good format so its not something I'd actually
recommend as a route for interoperability.
The OSG is open source though, so if you have the itch then feel free
to dive into the code and add write

Hi Robert -- I'm making good progress on the OpenFlight exporter plugin and

There is a customer requirement to be able to preserve the OpenFlight Object

etc. Currently, the importer
Also wanted to mention...
The two plugins could remain separate, but I'd probably need to use osgSim
to define any classes shared between the two plugins. For example, a class
derived from Group that does nothing more than save the FLT Object flags.

W.r.t UserData I'd suggest placing osgSim container for the extra

Hi Jeremy,
Good to see another release of osgWidget make it out into the
daylight. W.r.t the crash, try forcing the app to be single threaded.
Beyond that I can't suggest much. Alas I'm too busy myself for
experimenting with osgWidget yet, but I really really want to get
started with it.
Hi Jeremy,
As you know, I was waiting for this release to dive in.
So there I go. I will try to helpful.
Thanks a lot,
