Performers:

Could someone please clear up my thoughts on pfCycleBuffer.From the
examples and man pages, I'm a little confused on the implementation.

>From morph.C:

//// This is where the new cycle buffer is created.

    cbuf = new(arena) pfCycleBuffer(nSph * sizeof(pfVec4));

    ncoords = (pfVec3*) pfMalloc(pfGetSize(coords), arena);
    nnorms = (pfVec3*) pfMalloc(pfGetSize(norms), arena);
....
    colors = (pfVec4*) cbuf->getData();

/// How is it possible for cbuf->getData() to return anything since
//// nothing has ever been done to cbuf since it's creation. Where is all
//// the information allocated and created from the arena associated with
///// the cycle buffer?

I have large class which in shared memory which I have been using as a
single memory buffer. I'd now like to cycle the data in this buffer for data
consistency. Based on both the example and the man pages, I do not see
how the associate my single object of data to the cycle buffer memory.

Thanks.
