A 3D flythrough, also called 3D walkthrough, is a 3D rendered video or interactive video that shows the chief attributes of a building, product, or other physical items or locations. 3D flythroughs or walkthroughs are similar to 3D virtual tours, but are usually less user-driven.
3D flythroughs or walkthroughs are commonly used for marketing a development prior to completion, or to show off specific attributes of a development or product that are not immediately obvious.
