    FEA for entertainment

    did you look at the paper I posted? it's all about a hack that mostly fixes the odd-looking deflected shapes. Not accurate at all, but, basicly, you rotate your frame of reference on a per-vertex basis. http://graphics.cs.yale.edu/julie/pubs/Deform.pdf I just have to figure out how to compute...

    huh. Still, I an't imagine what they would have used FEA for on it. Anyways, any ideas on how to compute or store the stiffness matrix?

    Tron was mostly done on symbolics machines, and was mostly rigid forms translating around based on hand-keyframed channels- I doubt if they used any FEA for anything in it.... was "Nastran" around in 1981?

    FEA for entertainment

    I'm starting an open-source project developing a FEA solver for visual effects work. I'm attempting to implement this: http://graphics.cs.yale.edu/julie/pubs/Deform.pdf I don't know how to compute or store the stiffness matrix. Any tips, hints, or pointers?
