FEA for entertainment
FEA for entertainment
(OP)
I'm starting an open-source project developing a FEA solver for visual effects work.
I'm attempting to implement this:

I don't know how to compute or store the stiffness matrix. Any tips, hints, or pointers?

was "Nastran" around in 1981?

Anyways, any ideas on how to compute or store the stiffness matrix?

There's an old FEA puzzle/game called bridgebuilder (from memory) that may give you some pointers.

I remember a version of Colin Mcrae Rally which was developed in conjunction with PTC who did all the FEA for realistic damage modelling, from which they developed algorithms which ran as the game was played to add damage to the vehicle every time it crashed. The game was a roaring success.

Not accurate at all, but, basicly, you rotate your frame of reference on a per-vertex basis.

I just have to figure out how to compute and store the stiffness matrix. at this point, I have no idea. I'd venture a guess that it's stored as a 3X3 matrix, one at every vertex of the tet-mesh, but I can't find a simple answer anywhere. hopefully the 2 books will help.
