[away3d] AnimationSequence with collada or md2

[martin]

hello everybody,
how can i create an AnimationSequence with collada or md2.
i have the problem to cast the loader to an mesh/array of vertices.
what is the best way here.
currently i experiment with the as3geomexporter it is good but not
perfect, how can make an animation with collada or md2?
thx.
