For an architect, a flythrough can follow the circulation through a completed project and show how one space opens into the next. For a business, it can introduce a showroom, workshop, or facility to customers who have not visited in person. Within a larger production, it can connect interior spaces in a sequence that would otherwise require several separate shots.
The route should give important features enough time on screen. Depending on the location and intended use, a slower tour or a series of shorter passes may suit the project better than one continuous flight.
