A 3D walkthrough or an animated walkthrough is a popular additional service demanded with the 3D visualizations. It is an animation of walking through the virtual space, which provides an integral and comprehensive view of the visualized area.

Technically, it concerns a simple adding of an animated camera to the scene created in advance and subsequent rendering of individual pictures of its moves in the given space. As opposed to the static image, the 3D walkthrough has the great advantage of plasticity. An animation absorbs one more and attracts one’s attention and that just predestines it for marketing use. Customers have the opportunity to walk through interiors that are scheduled for construction.

The animated walkthrough is most frequently used in construction and architecture. It is a great way of enhancing the presentation quality. At present, it is possible to include customized solutions such as a walkthrough the animated interior in which the blinds are just going down, the light conditions are changing or colours and materials in the room are altering in order to show what impression the various alternatives of the interior give.

A special type of 3D view exists in which the camera does not move on the ground as if it was linked to a person but flies over the visualized area at greater heights. This method is used for exterior visualizations in particular.
