as I only have 1 view of the scene. When I have multiple views
though, I get a problem where zooming in on
on this.
If you got this far, let it be a reminder to spend a bit more and get
the NVidia GeForce/Quadro next time.

Why not render 3 passes into the same RGB texture but just write to one

Yes, it would be black on the red and green passes, but it

Hi,
this is known behaviour. Currently OSG caters for the common case where
the size and attachments of the RTT camera does not change frequently.
There are workarounds. I suggest you search the list archives for
runCameraSetup. You can also check how osgPPU handles resizes.

Hi,
Are you recreating the texture so that it fits the new view size? Are
you modifying the RTT camera viewport?
Above is however not needed when using FBO RTT, the texture size can
stay the same no matter what the final view window size is, unless you
want to match it pixel for pixel.

I'm having some issues with AutoTransform (scale to screen) and wide

Then make the aspect of the window
Hi all,
I've recently fixed some of these in our own code.
See here:

It was for ffmpeg on Debian sid:
apt-cache policy ffmpeg
ffmpeg:
Installed: 5:0.8-0.1
It should give some hints on where to start. I'm too busy to help currently.

Hi,
for an RGBA texture you would need data to be of size width*height*4.
Also, not sure what your magic 4 is in image - setImage. Put GL_RGBA
instead of 4.
Try:
image - setImage (width, height, 1,

Hi,
std::string has a constructor that you can pass a char* and size to.
string ( const char * s, size_t n );
This ignores \0's.
You can then it into a stringstream or possibly even directly put it
into stringstream.str()
