I am not sure what the scope of your question is, but in general VTK 
allows you to animate a scene by using the M key interaction. that 
combined with the endevent callback from the renderer can be used to 
continously update and display the model. Creating an illusion of a 
mass-spring would be a some application of a sinusoidal transform in 
displacement, rotation and/or scale. Google can help, 
http://www.dsprelated.com/dspbooks/filters/Mass_Spring_Oscillator_Analysis.html 
may give you some leads in simulating realistic objects.
