How are fluid simulations integrated into Rigid Body physics engines?
Is there any proof that simulations that mix Rigid Body physics and fluids (say SPH) can provide modeling for real world?
How does a frame of such mix work?
Say we have a wooden swing inside a box ...

Can I guess the appropriate epsilon for RDP (Ramer-Douglas-Peucker)?
I have sets of time series data which I display as charts in mobile applications.
To make the charts clearer, I simplify the sets by applying Ramer-Douglas-Peucker.
If I apply RDP to a small set ...
