The long term aim of the Praha4D project is to build a virtual model of the city of Prague where users could move freely both on the ground (walk or ride in a vehicle) and in the air (like flying in a helicopter). But the most significant feature is the incorporation of time - on small scale (movement of vehicles and eventually of people too), on mezzo scale (weather changes, day and night, seasons of the year) and especially on large scale (historical development of urban settlement).

The full-featured application could not be presented here. For technical reason there are only screenshots available. Few low-resolution movies could be found on the bottom of the main page too.

The first, prototype phase of the project was finished in the year 2006. A new completely re-engineered version is prepared now using the acquired experience. This new version is based on accurate maps and ortophoto-maps.
