[osg-users] how i can remove a sphere that is in a vector in the scene

[Robert Osfield]

Hi Alvaro,

In principle doing an Group::addChild(nodePtr) followed later by a
Group::removeChild(nodePtr) should remove it from the scene graph, so it
"should" work.

What you implementation is doing wrong is not something we can guess at
given the information provided.  Something, somewhere in your appliction is
doing things wrong, but as we don't have a code sample if front of us there
is nothing we can do to help.

Try creating a small example that does something like what you are doing,
but just focused on the sequence of operations { addChild(), rendering,
removeChild(), rendering } to illustrate what you are intending to happen.
There is chance you'll spot your mistake when writing this small example,
or if the problem persist you can post it to this thread so others can have
a look at it.

Robert.
