The rgl package should be able to do all this fairly easily. There is
no convenience API predefined to allow this with flowFrames, but as
Nishant said, there is only one extra step needed:

1. extract the expressions from a flowFrame as a data frame or matrix

2. use the standard rgl API

There are many examples accompanying rgl that should get you started.
