Lecture 18: Physical Simulation (45)

What does the con of "not physically based, dissipates energy (error)" mean? This is the method we used in our project and by constraining the position changes, it seemed to help realistically keep the cloth's shape at each time step?


How does the loss of energy in Verlet compare to that from implicit Euler?


I think the "not physically based" part refers to how Verlet Integration isn't really based on physics and is simply a way to get rid of excess energy. To me, the 10% thing we did in in the project seemed a lot more arbitrary than a lot of the other equations, etc we typically use.
