Hi, all:
I wonder if it's safe that I modify (add node or remove children) the
scenegraph in a custom updateoperation of a viewer in any threading model of
osg. This update operation is added to view by viewer-addUpdateOperation().If
not, what's the recommend time of doing this? Thanks.
is to look at the memory tracking tool you are
looking at, it may well be giving you false positives.
Robert.

Hi, all:
In my application, I set a rtt camera with a texture2d object attached whose
size is 4096*4096, and then I called tex2d-getTextureObject(contextID) to
obtain the texture. But as a result, the memory keeps increasing 60MB per
second. It's an MFC program. I wonder if there's any point

So @ttaw: the mentioned bugfix is an attachment of a post in the OSG forum.

You got me wrong, no need anymore for you to provide code.
I already fixed

so much:)
You again got me wrong .
The code I posted yet is not the bug fix itself, but just a test for C++11
support for your compiler.

Hi,all:
I want to get world coordinates of vertices in shader. I used:
osg_ViewMatrixInverse*(gl_ModelViewMatrix*vertex);
But the result is wrong if the geode is a child of an HUD camera node which
is in the scenegraph.It seems that the uniform osg_ViewMatrixInverse is not for
the HUD

In my opinion, the clip effect of a clipnode only affects its child nodes,
and a new clipnode only uses its own clipplanes. But the fact seems different
from this. In the following project, a clipnode with a cow is added to two
parents, but only one cow is shown. How can I
