Hi Performers,

I am interesting in writing a subclass of pfNode for use in code testing,
and have some problems/questions that I hope one of you could answer.

1) The only constructor listed in pfNode.h takes a pointer to a pfBuffer.
What does this pfBuffer do, and how do I create/aquire one to pass to the
constructor.

2) What's the correct way to isolate changes to the rendering state? Is
the following psuedo-code correct?

        pfPushState()
        pfFlushState()
        pfBasicState()
        // my code here.
        pfPopState()

3) I'm manually creating a bounding sphere using the following code,
        pfSphere bSphere;
        bSphere.center.set(0, 0, 0);
        bSphere.radius = 100;
        setBound(&bSphere, PFBOUND_STATIC);
Does anything else need to be done/set to prevent the node from getting
culled?

Thanks,
Damin Keenan.
