A new method for simulating squishy things has been developed. This technique is very impressive and can do many things like create elastic ships and detailed cloth wrinkles. However, making these simulations is challenging because the objects are squishy and every small mistake can affect the whole thing. The new technique can solve this problem by predicting how each small change will affect the whole simulation.
The old methods had limitations. They would split the problem into small pieces, but these pieces would not work well together, causing problems like overshoot. This would make the simulation unstable and potentially cause it to break. The new technique is different because it can predict how each small change will affect the whole thing. This is made possible by using a GPU to solve the problem all at once, rather than splitting it into small pieces. The technique also uses a precomputed co-rotated local perturbation subspace to predict how each small change will affect the whole thing.
The new technique is very fast and can simulate complex scenes in real time. For example, it can simulate a dragon with 100,000 elements in real time, and it can also simulate five barbarian ships with two and a half million elements at three frames per second. This is very impressive and has many potential applications. The new technique is also open science, so it can be used by anyone for free. This is a great time to be alive and to be working with simulations.
