Hi J-S.
There one more point about available data size if you are using uniform arrays
or uniform buffers:
you should pack your data into vec4's if it possible, cause uniforms counts
towards max size with some kind of slots, with one slot taking storage size of
vec4; if you declare your

Hi Sukender,
that does indeed look incorrect. opacityFactor was added by Alessandro so
I've not tested it myself.
GetTransparencyFactor() has already been used to determine the opacity of

I'm working in Windows XP with OSG-2.8.2.

Hi all,
I am using the MVPW matrix to transform vertices from object space
to window space. I get this matrix through the getMVPW method of
CullVisitor. Taking a look at the code, it seems that MVPW is (as its

matrices.
Hi Nagore,
But now, when I do a streaming, I want the remote expert to see the
rendered model too, i.e., the remote expert sees exactly the same as the
user can see in the glasses.
there are several steps to stream
: have an image sequence, code it, then send as some type of video stream.

My final words on this.
The frame buffer corruption is caused by the following.
osg::View::addSlave causes a default osgViewer::Renderer object to be attached
to the slave camera. This Renderer object has _compileOnNextDraw set to true.
This causes the next draw on the new camera to compile

First a quick English tip: when you begin a sentence with Look, it
indicates that you are frustrated with the person you are talking to. This
will usually get you a bad reaction but in this case I'll assume it's just a

Try without specifying optimizations, the same way as they did with the

If you associate a node mask to each type of node that may need to be
hidden using setNodeMask(), you can then modify the cull mask of the
camera to show/hide the nodes accordingly.
osg::Camera::setCullMask (mask) - would be called when the keyboard
button is pressed.

No, these variables already exist in the cmake file. To compile the osg fbx
