COMPUTER AIDED DESIGN IN URBAN ARHITECTURE 3D MODELING

The gap from the PC made sketches with the help of the china ink pen and ruler to the digitised drawing boards, high diagonal monitors and 3D projecting is truly spectacular. The increasingly efficient and more specialized programs allow the architects a whole range of facilities providing drawing commands and changes very easy to use, automatic rating, operating simultaneously in multiple windows, building sections and extracts of the plan, 3D views design and even projecting in virtual reality. Applications made to date using virtual reality technologies are characterized, essentially, by generating artificial world and immerging the user into this world. Evolution and effectiveness of such systems are conditioned, first, by the increased hardware performance (computers and specialized devices for interaction) so as to ensure a full immersion of man in the virtual world and, implicitly, a real-time communication with him.
