want to build 3d set to use in multiple shots from different footage


I’m learning the 3d aspect of Nuke.

I want to construct a set..basically a room to be built with geometry. I’ve never done this before.

I’m with Nuke, Maya and Boujou.

I’d like to do this with just Nuke and would like to know if it’s possible.

I have a 2d shot that pulled greenscreen keys from.
This shot is now a 2d layer that I will comp over a 3d background set.

I want to create this 3d room that the actor will be standing in.

I know the distance the actor was standing from the camera.
I know the height of the camera.
It was a locked shot, no camera movement.

So when I create the set out of geometry I want to be able to position the actor at a relative distance to the geometry knowing how far he was standing from the camera.

The whole room will not appear in the shot as the room will be in "reality" much bigger.

So I will want to use this room for other greenscreen shots taken from the real camera and show the room at different perspectives.

I’ve never done this before so I was wondering if this is possible from Nuke, or anything you want to say based on your own perspective.

Also if it’s better to do something like this in Nuke alone or better to build the set in Maya and then import that into Nuke?
