Could it be that your camera isn't being updated to look at your new models?

Let's take an example:
ShadowTechnique SHADOWMAP
It creates a texture and installs a shader program which makes shadow effects
by using the created texture.
So what you think happens by the second shadowScene?
On traversal it will create a new texture, by default install it in the same
texture

Hi,
It sounds like the Aero bug, disable Aero?
Believe Wojtek may have just submitted a fix for this to workaround the
driver bug, also the latest beta driver from NVidia fixes this for me, not
sure about a quadro card...
Might be worth trying the beta NVidia drivers?
Cheers

Hi Paul,
The easiest way to do it is use an osg::AutoTransform, this is like a
Billboard but can rotate to screen a whole subgraph rather than just
drawables. Billboard is lightweight for things like trees, but
AutoTransform is more flexible.

Hi Katja,
osgText uses a texture atlas to store it's glyphs and separate quads
to pull out the correct part of the texture atlas to get individual
text characters, this makes it impossible to just pull the text
texture directly and apply it to an ordinary geometry as the texture
coordinates would
I'm wondering is there any relation with that instruction :

Hi Robert, many thanks for the prompt reply - I've been playing around with the

billboard.
Thanks again

Hi,
I've been migrating some code from OSG 0.9.9 to the latest stable release
(2.8.3), and I've run into an issue when migrating from OSGProducer::viewer to
OsgViewer::viewer. I have three models, an airplane.3ds model, a sky.3ds model,
and a globe.osga model. All three models load correctly (t

Increasing maxScale does not appear to increase t

I don't know the cause of only the airplane showing up, but can

Second write out the completed scene graph to a .osg file just before

Hi Adrien,
When using multi-texturing you need to decide which texture units to
use then set up your texenv (if using fixed function pipeline) or
shaders to reflect this. Typically, in your case, one would use
texture unit 0 and texture unit 1, so you'd do something like:
stateset->setTexture

Hi,
I am using SDL to get input from a joystick so that I can integrate joystick

possible, and so far it appears that I mus

If you just want to use SDL to read joystick inputs, you don't have to
use SDL windows. You can use SDL for joystick inputs, and render OGS

I have OSG configured on Mac OS X with almost all optional dependencies
(except the big ones like Qt, etc). I installed them using MacPorts. I
suggest you use it, it's a breeze to install, it solves countless hours of
