Even if you had the 3D model, wouldn't it be an insane amount of work to take an essentially static 3D model and tell the animation program how to deform it to the resonant shape? Perhaps an FEM package would be easier. Many FEM packages (Ansys and CosmosWorks to name a couple) will accept a 3D model and will create animations of modal shapes.
