Back in the early 1990's we started producing the first
3D walk-through animated videos available. The computers
were a lot slower then and we couldn't have the detail
we have today but still these short movies were incredibly
successful in sales and architectural presentations.
The idea of a walk through is to take a viewpoint from
eye level and guide a viewer through a 3D scene. Sometimes
we may break the rules and "fly" a little, achieving angles
that you would not normally see, but generally we try to
show exactly what the viewer would see if walking through
Walk through normally refers to interiors, with exteriors
being referred to as fly-by.
