Describe how you would implement a virtual set.
I.e. a system that will place live actors, recorded by a video camera, in a computer graphics environment. The visuals should match such that actors appear to actually be in the CG world.
In particular, consider doing this in real-time, either for live TV broadcast, or for pre-visualization of finished effects.

No code is expected for this assignment - just e-mail me a text document describing (at a reasonably high level) how you would do it.

Look through all of the graphics techniques that we've covered so far in the course, and identify those that you would use, and any important details in how you would use them to make the virtual set realistic.

Also identify any other technologies, or pieces of information, that would be needed.

Some things to consider:

• How to do the blue-screen compositing in the computer, rather than with special video equipment.
• What if we want to be able to have some virtual objects appear in front of the actors, and others behind them?
• Would multiple cameras (to cut between) be a problem?
