Hi delta,
Would it be possible to sign with your real name so everyone can address you
correctly? :)
What kind of task would you like to solve with TBB?
OSG uses Openthreads for all multithreading issues.
Thank you!
Cheers,
Torben

Hi,
I have a problem concerning osg integration in Qt. I took the example of
osgViewerQt as a base and implemented it in my project. When I execute frame

i work with osg for about 3 month now using it with win32 console apps and mfc.

Hi Werner,
it seems to be installed: I can find libfreetype6 in version 2.3.7. On the

Hello all,
I am new to OSG and I am having trouble implementing something in my

Hi forum,
I was going through the example osggameoflife and pondered over the texture
specification part to visulize the game.
I used to know that the texture coordinate s,t,q all has to be between 0.0 and
1.0.
At one part of the example the texture coordinate has been specified as
Hello Igor,
So, at each frame the camera's matrix is overwritten by a new matrix which is
taken from MatrixManipulator.
In the past few hours two people on this list told you that if you
wanted to use your own view matrix you needed to set no camera
manipulator... (Paul Martz and Mourad
Hi Sajjdul,
I used to know that the texture coordinate s,t,q all has to be between 0.0 and

No, it does not have to be between 0.0 and 1.0. It can be any value.
For Texture1D/2D/3D, what happens outside the 0.0 to 1.0 range is
specified by the wrap mode (texture-setWrap(...)). You can
Hi,
I want to change the 3D model dynamically at the runtime.
I have inatialize my node at :
_model = new osg::Node();
_model = osgDB::readNodeFile(model1.osg);
and when I do a particular action, I would like that the 3D model changes, I
write this :
_model = osgDB::readNodeFile(model2.osg);
Hi Lucie,
I think this is a simple C++ issue.
First you create _model which is a pointer on a node.
Then you make a new node and set _model to store its adress.
Next, you load a new node and set _model to store it again. So the first
thing is, you don't need to do _model = new osg::Node();
So

Greetings,
I have some mirrors in my scene, which use RTT for reflections. I'd like to
make sure that, if the mirror isn't visible, the RTT pass doesn't happen. A
simple frustum check should be fine. If the mirror is in the scene camera's
frustum, it would be okay to render the reflection
Hi Frank,
What I'd like to do is add a frustum test here, so I can avoid doing the
reflection RTT if the child sub-tree isn't even viewable by the camera. Is this
possible?
In your cull callback you can cast the osg::NodeVisitor to a
osgUtil::CullVisitor, and I think you can then call
Oh, nice, thanks!

I think you misunderstand how the projection matrix works
setProjectionMatrixAsPerspective is defined with the parameters (vFov, aspect,
near, far)
vFov sets the vertical field of view of the perspective meaning you will have a
wider viewing angle the larger the value gets.
aspectRatio is
I'm going to preface my comment by saying I've never done an effect like this
before. I am, however, interested in how this could be accomplished.
Adding in the wiper effect adds a particularly difficult layer of complexity to
an effect like this.
I would still suggest using a shader to do
