Truss Test Slider
A simple point-mass / damped-spring simulation. It's not very sophisticated, just calculating spring and damping forces (per spring), then acc, vel and pos (per node). Integrator is leap-frog, running at 4000 Hz (I can reach same stiffness with RK4 @ 1000 Hz, but execution is more than 4 times slower, so it doesn't pay off).
