This day we looked at several papers regarding swimming creatures. I thought the idea of modeling both the forces of water on the characters as well as the characters on the water makes sense - there's always two sides to every interaction, and I feel like it might not look correct if you don't model that. The papers that didn't do that didn't have such great results. The characters looked like there was no resistance working against them when they were swimming, like they were just doing the motions in air.
We also looked at a paper on soft body locomotion - characters that bend and stretch and have no skeleton. I thought the way they modeled the muscles in the characters was interesting, but could potentially be limiting. They had good results some of the time, but other examples, such as jumping and rolling, looked extremely bizarre. The motions that were good were really good, but the motions that were bad were really bad. I wonder if that would be solved by adding one more type of muscle, since they only had three: longitudinal, radial, and helical. I don't know what it would be, though.
