This is a video that showcases some of the different ways to tune the Jello simulation that I wrote. The first is comparing a "stiffness" parameter that arises from the fact that the Jello is being modeled as a mass-spring system. So the stiffness roughly corresponds to the stiffness of the virtual springs. The second part shows the differences between integrators used to solve the differential equations. The differences in behavior are quite slight, especially between RK2 and RK4. However, on the back end, RK4 is quite a bit more stable, so that is what I use the most. However, I think that RK1 has the most "Jello-y" behavior, although that is anecdotal.
The scene itself was modeled in Maya, rendered in Mitsuba, and the entire thing composited in After Effects.
