Realistic modeling of bird flight animations

Creating Realistic Animations Using Video

Generating realistic animations of passive dynamic systems such as rigid bodies, cloth and fluids is an important problem in computer graphics. Although several techniques for animating these phenomena have been developed, achieving the level of realism exhibited by objects in the real world has proved to be incredibly hard. We argue, therefore, that an effective method for increasing the reali...

Biomechanics of bird flight.

Power output is a unifying theme for bird flight and considerable progress has been accomplished recently in measuring muscular, metabolic and aerodynamic power in birds. The primary flight muscles of birds, the pectoralis and supracoracoideus, are designed for work and power output, with large stress (force per unit cross-sectional area) and strain (relative length change) per contraction. U-s...

Anticipatory Manoeuvres in Bird Flight

It is essential for birds to be agile and aware of their immediate environment, especially when flying through dense foliage. To investigate the type of visual signals and strategies used by birds while negotiating cluttered environments, we presented budgerigars with vertically oriented apertures of different widths. We find that, when flying through narrow apertures, birds execute their maneu...

Bird Flight - Insights and Complications

A Flight Mechanics-Centric Review of Bird-Scale Flapping Flight

This paper reviews the flight mechanics and control of birds and bird-size aircraft. It is intended to fill a niche in the current survey literature which focuses primarily on the aerodynamics, flight dynamics and control of insect scale flight. We review the flight mechanics from first principles and summarize some recent results on the stability and control of birds and bird-scale aircraft. B...
