Verlet vs Sequential Impulses
Posted: Fri Jan 05, 2007 8:33 am
I've been wondering how Verlet compares with Sequential Impulses for cloth. To get started, I wrote a simple pendulum simulator. I noticed a few things:
- Split impulses are less energetic than Baumgarte. It seems that semi-implicit Euler is removing energy and Baumgarte is adding some back.
- Verlet damps faster than Split Impulses, but it does oscillate (contrary to my previous assumption).
- Verlet gets more energetic when there is some initial stretch. SI is more calm.
