If I understand correctly this is not possible in XSI per the answer I
got in a thread like this a couple of years ago.
In Houdini it was simply selecting a camera for an output/render and
feeding that output into their integrtated compositor or for example
as an image driver of surface attributes, then advancing frames with
moving camera would update render and compositor and surfaces etc.
Slow unless lots optiomized, but useful for prototyping concepts and
experimenting before final renders.
