To confirm this direction of our researches, we propose a sample of video clip as one of the first examples of this topic. In our opinion, it is an indisputable instance of application of computer animation. The idea is to show how one of the visualization techniques has been used for large town-planning project in Moscow. It also exploits speculative question about comparison of two different ways of space simulation: endoscopes and computer tools. This kind of comparison has been made, for example, in Conferences of the European Architectural Endoscopy Association (EAEA) [1 - 3, 5 -7]. Our line of thoughts is in this direction - for each context of problem and project a suitable instrument for space simulation must be considered. A suitability issue is a matter of understanding particular case of practical or scientific task.
