HI Harash,
If you have a separate card for the frame grabber then your system will be
needing to copy the data from the frame grabber card into main memory then
copy it back to the graphics card. this will need to be done regardless of
whether you use the frame grabber API or configure via the
Hi,
I'm playing with the osgcompositeviewer example in order to load and show the
axes in the scene. I want that when I rotate the model in the first view, the
axes get updated accordingly, but I don't want them to change position or allow
the user to zoom them.
So, I got this thing running
Hi Robert,
thanks for the info! In the example the function keys worked right!

Thank you!

Hi,
I'm currently working on a visualization project where stereo-camera will
be used.
I'm setting up six cubemaps for reflection. The world object is reflected
well in the cubemap, but the sky, is not rendered properly, so the sky is
reflection is wrong.
The sky is created from the source of
HI Mikhail,
Thanks for the example. I've reproduced the crash using the example and
been reviewing the osg::State handling if the _appliedProgramObjectSet and
can see the mechanism by which the container gets accessed inappropriately
by the draw thread when a Program::PerContextProgram object
Hi,
Searching forum i've found such topic

Hi Robert,
The OSG automatically reference counts Nodes and other objects in the scene
graph. If you want to remove Nodes or other objects from the scene graph
you need to call the appropriate methods to removing them. If you want to
remove a child from a group then you simply call
Hi Mikhail,
I have resolved the threading bug associated with
osg::State::objectDeleted() by removing the _appliedProgramObjectSet
container that was the cause of the threading bug. Reviewing the OSG code
base I found that the need for this container centered around
State::reset() method that is

Hi,
Ok, i was mislead by previous thread and setting NULL to ref_ptr. So, i'm using
removeChild, as it should be and got crash. I'm doing this in such way:
Code:
osg::ref_ptr osg::Geode geode = new osg::Geode; // on start
osg::Geode* g = geode.get(); // store pointer to my geode somewhere
Hi Robert
Your crash is down to retaining a c pointer to an object that has been
deleted. This dangling pointer issue is exactly why smart pointers are used
in modern C++ application.
Lots has been written about ref_ptr usage here over the years, as well as
docs and osg books that discuss it. So

Hi,
I am attempting to create some osgText which has a very large size value. I
noticed that if I keep the size parameter under 50 it looks fine. If I crank
it up to say 500, the text looks fuzzy on the edges and just bad. I am using a
TTF font. I am pretty new to using text so maybe one
