MAYA实例：鸟类翅膀骨骼设定教程（英文）

　　If you have to make a wing yourself there are of course far simpler ways - the methods shown here were required specifically for the project in question.　

　　It must be stressed from the outset that it is often near impossible to create a single 'Master'　creature who performs all things for all shots. Much work on this project involved painstakinkly tailoring the structure of the bird for different shots. For the purposes of a tutorial however, it will be better to just cover this pre-vis/preparatory work which in the main, served as a template for later articulation and deformation structures within differing shots.　

　　Firstly the feathers of the wing were modelled from simple nurbs planes. The possible particle approach involving sprites was initially discarded as fine localised control was required at the single feather level both in terms of　texturing and animation. It was decided that for shots where the bird is small in frame, a proxy wing would be used - i.e. a simple flattened nurbs sphere in the shape of a wing and top projected with a matching texture of the feather arrangement.
