Critical essay by Rodion Eremeev The world always generate new directions in Art and Architecture. It always implies new techniks and fabrication ways. During the 20th Century it were a lot of different variety of styles – functionalism, constructivism, brutalism, metabolism, etc. Nowadays is a time of a digital ways of design in Architecture. Neil Leach book  “Digital Tectonics” distinctly explains what does it mean Digital. How does it affect on architecture, design, art, live… And also explains how it were developing through the years. In chapter “Historical Perspective – Future Prospect” Mike Cook represent to our attention three key factors that were influencing on the form – material,ability,need. By this factors Mike try to explain that is fundamental determinants of what we build. On the different examples like projects and experiments of Gaudi or Frei Otto, he is showing how they used to work with modeling, simulation and fabrication without any computer tools. He is thinking that now is great ability than ever before to create a free form. That old physical methods of modeling and describing form are still relevant, but now is digital age. Digital tools and methods will help to humanity to create buildings that would conserve materials and energy. As I understand, Digital Tectonics means that you can go ahead from sketches on the paper to really difficult simulations. That means that now, computer is really relevant tool for architects to design intelligent structures. Human mind can imagine and produce a lot, but it has a limit and from that point to develop more complex things we should use computer to help us with it. From idea to paper, then to 3D model and simulation, then to digital fabrication – that all involves Digital Tectonics.
