Abstract

The coordinated flight of bird flocks is a pleasant and attractive sight. Flying flocks can be classified by their formation - cluster formations or line formations.

In cluster formations, typical of small birds as well as fish and herds, the animals are organized in irregular shapes.  In line formations, on the other hand, the flocks are organized in a characteristic pattern, such as a line, 'V', or 'U'. These formations are typically two-dimensional and exhibit a high degree of regularity in spacing and alignment. They are common in flocks of large birds, such as waterfowls, cranes, and pelicans.

Most previous works have addressed the animation of cluster formations. This thesis introduces a technique for realistically animating the aggregation of flocks of birds flying in line formations.

Our contribution is threefold. First, we propose to distinguish between the formation stage and the steady flight stage. This differs from the previous approaches, in which the same rules govern the whole simulation. Second, we suggest a novel set of rules for the formation stage, appropriate for line-formation flocks. Finally, we show how steady flight patterns can be produced by combining a data-driven approach with an energy-savings model.
