When using the Division dV/MockUp software we much prefer to use the
former method. This means you do not need to change the projectors if
you want to create a false perspective or exagerated stereoscopic view.
The inter-view lineup if very precise, and projector configuration does
not need to be changed if you want to switch to 'fat-desktop' mode,
group-station mode, or whatever.
