Motion control 2004-07-13 - By Anthony Ware

James,
Well, this is usually done the opppsite way around - replicating an existing
real-life camera path in a CG package like tS so that CG elements can be
combined with the real-live footage.
There are two such motion match packages I am aware of that support
trueSpace, PFTrack (formerly known as Icarus) and SynthEyes. Neither are
cheap - motion match ability is a 'big boys' toy and comes at a cost. The
results are usually highly dependant on having suitable live footage to be
motion matched in the first place as well. Having tried both PFTrack (when
it was Icarus) and SynthEyes I found SynthEyes to be the easiest to
understand and use but others may disagree.
The PFTrack website appears to be down but the link is:

and for SynthEyes:

The cheap and dirty solution is to set up the live action shoot, measure
everything accurately - camera location, location of some markers on the
set, camera lens data etc. and then build a virtual set in tS to try and
match. There is a lot of trial and error and jiggery pokery required to get
anything like a decent result with this method, but it is cheap.
You pays your money and you takes your choice....
