Hi,
have a look at the render to texture examples (grep for attach). You
create an RTT camera, attach your RGB texture as input, create an RGBA
output texture and attach this as the output, then in a shader do your sums.

I have some question about texture into OSG.
I would like to save the 3D model by serialization. All it works except the

You can e.g. put the RTT camera under a switch and switch it off after
the first frame. The
Hi Loic,
to work with the textures of your model, 'osgconv' is probably the good
tool:
osgconv -O OutputTextureFiles file.ive file.osg
To know more about one format you can use this command:
'osgconv --format FILE_EXTENSION'
and
'osgconv --formats'
to see the full list of avalaible

Hi,
I use VirtualPlanetBuilder for my internship project. I have to describe in my
internship report the opportunities offered by VPB but I can't find
documentation.Could you tell me if you found documentation or explained me the
features of VPB, the data formats it supports, etc.?
Thank
Hum,
actually the path into the osg model is absolute and therefore bad. The osg
model comes from 3ds model, and maybe when it's converted, I must force to
create relative path rather than absolute.
Otherwise, it seems that is working with osgconv.
I will try it :)
Cheers,
Loic
Hi Jimmy,
The OSG doesn't support general multi-threaded update, you have to
serialize all the updates and make sure they happen during the update
phase of the frame.
Support for general mult-threaded update would complicate the scene
graph design, implementation, usage and have a big hit on

The documentation for VPB is still rather sparse, but you can find it from :

Do you want to create an application that takes the model and output a new

Hi,
Indeed, I had seen this documentation but it does not explain in detail what

Just reporting a compile problem in OSG trunk in osgQt. See compiler
output bellow.
The problem was noticed on Qt 4.4.0. While it is not present on some
more recent Qt versions.
Probably broken compatibility with older Qt.

I believe that osgQt has probably failed to build now rather before as
previously osgQt required QWebKit to be installed, but this
requirement has now been relaxed by moving the QWebKit integration to

Alas, in my refactor I clearly didn't

Note, if you do not want to change the internal scene structure in the file, do not use

You can set OSG_OPTIMIZER=OFF before running osgconv if you don't want
