Ancient Wings: animating the evolution of butterfly wing patterns

Biosystems, 2003
Character optimization methods can be used to reconstruct ancestral states at the internal nodes of phylogenetic trees. However, seldom are these ancestral states visualized collectively. Ancient Wings is a computer program that provides a novel method of visualizing the evolution of several morphological traits simultaneously.

The formation and maintenance of a leading-edge vortex during the forward motion of an animal wing

Journal of Fluid Mechanics, 2007
A simple model is presented to explain the observed generation of a quasi-steady vortex at the leading edge of an animal wing that rotates in a horizontal plane about a body-centred axis. Vorticity formed by separation at the leading edge is transported outwards by a spanwise velocity field generated by two sources of spanwise pressure gradient, one ...

Numerical animation of the flow over the upper surface of a butterfly's wing

1996
The objective of this study is to present an animation of numerical simulations performed on a two-dimensional model representing the cavities found on the upper surface of a typical butterfly wing. Numerical results were obtained using a mixed Eulerian-Lagrangian vortex method.
