It seems like a three dimensional spring structure might be useful for modeling something like a bouncy rubber ball. For something like fabric it seems clear how we can build a corresponding a 2d sheet spring structure to model its movement. But for a bouncy ball, some aspects of how we would model it as a 3d spring system aren't clear to me- for example, what would the internal structure of the spring system look like? It seems simple to map a piece of fabric onto a 2d sheet spring structure since a piece of fabric is structurally similar to the sheet structures we've been seeing in the slides, but a bouncy ball in reality isn't a dense object through and through like the block structure shown in the slide, it's filled with high pressure air. How do we model the effect of this pressurized air as a structure of springs?
