I'm wondering if I understood the pfBuffers correctly...
My Performer application uses two processes. The first process does
the usual Performer stuff (setup, set viewpoint, pfFrame,...) and the
other process runs the interface. It looks something like this:
performer intializations
create scene with some lightsources
if (fork() != 0)
{
while (notdone)
{
setviewpoint
pfFrame ();
}
}
else
{
create new pfBuffer for adding objects
select the buffer
run interface
}
In the interface I create new objects in shared memory. After a object
is created I do a scene->bufferAddChild (obj); and
objectsBuffer->merge(). This works fine.
Now, the problem is deleting objects. I thought I could do it in the
same way:
//i'm still in the interface process so the current buffer should be
//the one I created
scene->bufferRemoveChild (obj);
objectsBuffer->merge ();
This is when Performer crashes...
