"Xplodar" is tiny demo of deformation simulation using Finite Element
Modeling (FEM) technique. Done for similarly-named university course.
Nothing fancy, just simulates some deforming model and lets you
interact with it.
Basically, it's direct implementation of pretty standard stuff:
tetrahedral elements, linear shape functions, Green's tensor, explicit
integration. All this and more is nicely described in papers like Graphical
Modeling and Animation of Brittle Fracture, some nice real-time
tailored optimizations are in Real-Time Simulation
of Deformation and Fracture of Stiff Materials.
You can see that the papers are on fracture, but Xplodar doesn't have
one. Oh well, the eternal reason named "lack of time" :)
